Summary: Come 2025, say hello to “bridgeless deposits”! This means you’ll be able to accept funds from just about any blockchain out there and have them automatically credited and settled wherever your treasury is. Plus, your users won’t have to worry about navigating any bridges--they can keep it simple! This playbook takes a closer look at the engineering patterns, frameworks, and controls that 7Block Labs employs for their Any‑Chain In, Any‑Chain Out accounts. It’s a deep dive into the strategies we use to make everything work smoothly. You’ll discover some really detailed designs, along with easy-to-follow build instructions and smart risk controls that you can put into action this quarter.

Bridgeless Deposits: Engineering ‘Any‑Chain In, Any‑Chain Out’ Accounts

With liquidity becoming fragmented and new Layer 2 solutions emerging almost weekly, the need to be able to “move value anywhere” is now a big deal for boards. Plus, the rising trend of intent-based execution is only adding to this urgency. It’s definitely something that’s on everyone’s radar these days! What’s the goal here? It’s all about making it super easy for customers to deposit value on any chain they want and get access to their spending balance right where they’re using your product. Forget about needing browser extensions or dealing with those complicated bridge interfaces. And definitely no more headaches like “refuel gas first.” We're making things simple!

In this post, I’m going to really dig into how you can actually make this happen. We're going to dive into all the key elements you need to know. We’ll chat about when to pick certain rails, share tips to steer clear of routing mistakes, and go over some solid ways to double-check your settlements. Let’s get started!.

Let me give you a quick recap of what went down in 2025. I've also got a reference architecture that you can customize to make it work for you. Plus, I’ve included some real-world examples that should come in handy when you’re planning your sprints.

What changed in 2025 (why bridgeless UX is now feasible)

• USDC has seriously upped its game with some lightning-fast cross-chain features! Thanks to Circle’s CCTP v2, sending USDC is now a breeze--it can go from taking minutes to just seconds! The “Fast Transfer” option and those clever smart-contract “Hooks” make all the difference. Pretty cool, right? "Hey, just a heads up! The old version (v1) is going to be phased out starting on July 31, 2026. So mark your calendars!" What this means is that you can pretty much deposit USDC across different chains in no time. Plus, you can even automate some actions right after you make that transfer. How convenient is that? Check it out here.
• The intent rails have really hit their stride! So, ERC‑7683, which is all about cross-chain intents, has made the leap from being just a concept to something you can actually use with the Open Intents Framework (OIF). Pretty cool, right? Basically, this lets apps connect through a common network and a standardized order system, so they can handle trades in any direction without having to set up those complicated market-making processes. Also, Across V4 has really upped the game with a ZK-verified universal verifier, which speeds up chain expansion even more! Feel free to check out all the details here. It's a great read if you're curious!

Great news! The clearing and settlement layers are officially up and running! Everclear, which you might remember as Connext, is now live on the mainnet. This means it’s going to be way easier to handle liquidity flows and cut down on those pesky rebalancing delays for intent bridges. Exciting times ahead! Wow, this is a total game changer for dealing with big deposits! If you're curious to learn more about it, check out the details here. You won't want to miss it!

Multi-chain token standards have really hit their stride at last! Chainlink CCIP has just launched Cross-Chain Tokens (CCT), which allow for some pretty cool programmable token transfers! In the meantime, Axelar’s Interchain Token Service (ITS) and Wormhole’s Native Token Transfers (NTT) have rolled out some official ways to handle burn-and-mint for native distribution. LayerZero’s OFT has really taken off as a popular standard for omnichain tokens. This is awesome news! It’s going to really help cut down on wrapped-asset fragmentation--not just for your tokens, but also for the tokens of your major partners. Learn more here.

• With permissionless interoperability, it's become really effortless to add new chains. Thanks to Hyperlane’s permissionless deployments and modular security (ISMs), spinning up new app chains and rollups is a breeze. Just take a look at Celestia’s plans for 2025 - they’re a perfect example of what’s possible! Find out more here.

Gas abstraction has evolved from just an interesting concept into a practical tool we can actually use now. Hey there! So, good news! The Wallet Call API (you know, EIP‑5792) and ERC‑4337 paymasters are now all set in the big SDKs. Plus, services like Bungee’s Refuel can help you fill up your gas on the target chain. Pretty cool, right? This is super important for turning “bridgeless” onboarding into a reality! You can dive into all the details here.

Here’s the deal: you can easily create accounts that accept deposits on different chains and show your settled balances on your preferred operating chain(s) in almost no time at all! On top of that, they've got some really strong security features, and users don’t have to stress over any bridging issues.

A reference architecture for “Any‑Chain In, Any‑Chain Out” accounts

Check out this solid blueprint we swear by at 7Block Labs! Don’t hesitate to switch up the component selections to better suit your assets, the chains you’re targeting, and your comfort level with risk.

1) Deposit surface (Any‑Chain In)

• Addresses
• EVM: We’ve got you covered with per-user deterministic deposit addresses, no matter if you’re using smart accounts or EOAs on the networks we support.
• Non-EVM: So, we've figured out how to handle deposit identifiers--like Solana PDAs--and we’ve also set up memo-based routing when it's a good fit.
• Watchers We've set up event listeners for each chain to keep track of deposits. They basically monitor a few key details, like the token contract, chain ID, and the amount being deposited. When it comes to classification, we’re focusing on stablecoins like USDC, well-known assets like ETH and WBTC, or hey, even your own token can fit the bill!
• Decision Engine (Choosing the Right Rail)
• USDC: If you're looking for a quick and easy option, I’d recommend checking out Circle CCTP v2 Fast Transfer! It’s pretty much the best way to go. Also, you can hook it up to a receiver on your “ledger chain,” which lets you add to your internal balance right away. Super convenient, right? Take a look at this! You can check it out here: circle.com. It’s pretty interesting stuff!
• Your Token: It's likely a good idea to go for a solid multi-chain standard that you can actually manage and have control over. If you're looking for strong security, rate limits, and the ability to make programmable transfers, definitely check out CCIP Cross-Chain Token (CCT). It's a great choice! If you're looking for more details, you can check it out here: docs.chain.link. Happy exploring! If you're looking to tap into a wide-ranging ecosystem, LayerZero OFT is definitely the way to go. It’s like having a burn/mint option or a handy adapter for existing tokens. Super versatile! Learn more here: (docs.layerzero.network). If you're looking for multi-VM compatibility--like EVM and SVM--then definitely give Wormhole NTT a look. They’ve got some great CLI tools that can really help you out! You’ve got a couple of options for your tokens: you can either go with the hub-and-spoke model or try out the burn-and-mint approach. Here’s the link: (wormhole.com).
• Finally, Axelar ITS makes it super easy to keep your custom token features in check using just one token address across all EVM chains. Details here: (axelar.network).
• Other Assets: Make sure to use an intent router or aggregator that works with ERC-7683/OIF. It's a good idea to include SLAs and have some fallback bridges ready, just in case!
• Gas Abstraction Start off strong by covering that initial deposit with an ERC-4337 paymaster. If you’re working with non-AA wallets, don’t forget to integrate the EIP-5792 Wallet Call API. It’ll let you batch those gasless calls wherever it’s available. It’s a real game-changer! Oh, and if you need to, you can easily top off your native gas at your destination with Bungee Refuel. It's super convenient! Hey, take a peek at the details over here: (docs.erc4337.io).

Here’s a streamlined "DepositIntent" that covers everything you need: it shows the source chain, the asset involved, the route you’re taking, the expected settlement chain, and the credit policy.

2) Settlement and credit (Unified account ledger)

• Settlement target First off, choose a main ledger chain. This is typically your go-to L2, you know? If you're looking to beef up your security a bit, think about adding a shadow ledger on a different chain too. It can offer that extra layer of protection!
• Programmable settlement Whenever you get the chance, make sure to use CCIP Programmable Token Transfers. They let you send tokens together with any additional info or instructions right to your ledger contract, all in one smooth cross-chain transaction. It's a pretty handy feature! This could involve tasks like adding funds to an account, sending out a receipt, or tweaking those risk counters. Take a look at this link: (blog.chain.link). It's pretty interesting! With CCTP v2, you have the option to set up a Hook on the receiver's side. This will kick in right after minting and make a call to your ledger. Pretty neat, huh? You'll get the same results in just a few seconds! It's super quick and easy. More details at (circle.com).
• Clearing If you’re juggling a bunch of intent fillers or bridges, teaming up with Everclear could really simplify things for you. It can help you maximize your flows and save you the hassle of constant rebalancing and capital lockup across various chains. If you want to dive deeper into it, check this out: (theblock.co). It has all the details you need!

3) Payout/withdrawal (Any‑Chain Out)

• Orchestrator
  So, when you have an asset and a specific chain that you need, pick the outbound rail by keeping this order in mind: first focus on canonicality, then think about latency, and finally consider cost.
• Example of Rail Policy (by Asset).
• USDC: If the destination chain has support, definitely opt for CCTP v2! If that’s not the case, you can go ahead and use an OIF/7683 solver to send it over to a USDC domain that’s compatible. Then, just wrap things up using CCTP on the last leg! (theblock.co).
• ETH and Gas Tokens: If you’re looking to make quick transfers, you might want to try out the intent layer, like Across V4 or something along those lines. It’s super convenient! You can pay back the origin whenever it works for you, just remember to keep tabs on those caps. (across.to).
• Your Token: It's best to stick with the native OFT, NTT, ITS, or CCT if you want to keep everything balanced. Try to avoid those wrapped forks! (docs.layerzero.network).
• Gas UX
• Keep it simple by giving users the choice to “withdraw with gas included.” Just throw in a little extra of the native token for the destination chain, and you’re all set! (docs.bungee.exchange).

4) Controls, risk, and observability

• Rate limits and circuit breakers: These are essential tools that help manage how much traffic a system can handle. Rate limits put a cap on the number of requests a user can make in a certain time frame, which is super helpful for keeping things running smoothly. Circuit breakers, on the other hand, are like safety nets--they kick in when a system is getting overloaded or starts failing, preventing it from crashing completely. Together, they keep everything balanced and functioning like a well-oiled machine. With CCIP, you can easily set limits for each token and lane that align with the quotas in your ledger contract. It's super convenient! Take a look at this: (docs.chain.link). Would love to hear what you think!
• Multi-bridge policy firewall Glacis is definitely the place to check out if you’re looking to gather GMPs like Axelar, Wormhole, LayerZero, CCIP, and Hyperlane. It’s a solid resource for all those! It helps you keep tabs on who can access different routes, set the rules for quorum, and streamline your adapters. With this setup, you can easily say something like, “only this specific source contract on chain X is allowed to kick off function Y across these bridges.” If you want to learn more, check out this link: docs.glacislabs.com. It’s got all the info you need!
• Proving and receipts Hey, just a quick heads-up: it’s really important to keep your cross-chain message IDs and provider receipts secure. You don’t want to lose them! Hey, you know what’s smart? Setting up a public "Proof of Credit" endpoint. It’s super handy for auditors who need to take a look and verify things.
• L2 due diligence Make sure to stay updated on the L2BEAT security stage and the decentralized application (DA) assumptions for any chains that you’re accepting deposits on. It's a good idea to keep track of those! It could be a good idea to bump up the limits for each chain until the proof systems are running smoothly. If you want to dive deeper into the specifics, check this out: (medium.com). You'll find all the juicy details you need!
• Audits and upgrades
• Just a heads up: whenever you're tweaking the bridge adapter, think of it as a high-risk deployment. Better to be safe than sorry! Make sure to follow a solid diff-audit process, similar to the one that Across uses for their OE diff audits. If you want to dive deeper into this, check it out here: blog.openzeppelin.com.

Concrete patterns you can ship

Pattern A -- Canonical USDC, seconds‑level credit

Goal:

When a customer transfers USDC on Chain A, your product jumps into action and instantly adds it to their balance on Chain B--like, really fast! Plus, they'll get an on-chain receipt right away to keep for their records.

First things first, kick things off by using CCTP v2 Fast Transfer on your source chain. Alright, so here’s the deal: once you're on the destination chain, just make sure your CCTP Hook is set up to kick off the function Ledger.credit(user, amount, srcChain, txId). That’ll take care of things nicely!

• Lastly, create a cross-system receipt ID that includes details from both the source lane and the message. This way, customers can easily check their balance, and the backend reconciliation remains steady and trustworthy.

Why Now

With the new upgrade to v2, the time it takes for USDC cross-chain transactions has dropped dramatically--from about 13 to 19 minutes all the way down to just a few seconds. That's a huge improvement! And it also brings in Hook composability, which totally simplifies the whole crediting process.
Hey there! If you're still using v1, it might be a smart move to start thinking about migrating to v2 before v1 gets phased out on July 31, 2026. Planning ahead can really make the transition smoother! (theblock.co).

Pattern B -- Your token as a true multi‑chain asset (no wrappers)

Goal:

Make sure your utility or RWA token can be used seamlessly across different blockchains without having to divide your liquidity.

Hey there! If you’re on the hunt for a safe way to chat, backed by Oracle, and you also want a managed explorer, you should definitely consider rolling out a Chainlink CCIP Cross-Chain Token (CCT). It could be exactly what you need! You’ve got access to rate-limited pools and the ability to set up programmable transfers. This means you can start staking as soon as you arrive, manage those fees, and do a whole lot more! If you're looking to dive deeper, check out the Chainlink docs. There's a ton of information waiting for you there!

If you’re looking for robust OFT semantics and seamless integration, then LayerZero OFT is definitely a great pick! You can easily create or destroy tokens and connect them with the ones you already have!
Check out all the details over at the LayerZero documentation. You’ll find everything you need to know!

• Looking to connect with multiple VMs, such as SVM and EVM? Wormhole NTT could be just what you need! You can easily set up burn-and-mint for that native fungibility, and thanks to their NTT CLI, getting things deployed is super simple. Hey, make sure to take a look at this link for Wormhole: Wormhole. It's got some great info on how to get started with native token transfers!

Hey there! If you're into single-address EVM deployments and want to keep your custom logic just the way you like it, you might want to check out registering with Axelar ITS. It could be a great fit for you! They've got your back! Just head on over to Axelar to get rolling.

Trade-off Notes

• CCIP: Offers a robust defense-in-depth strategy along with excellent programmability.
• OFT: It's really popular and has a ton of app users, which makes it super easy to get into.
• NTT: This one really zooms in on connecting various VMs and gives you clear control over the native supply.
• ITS: It keeps the token functionality intact, all while ensuring it has the same address across different EVMs.

Pattern C -- “Invisible bridge” checkout with intents

Goal: Let Users Mint or Pay on Your Target Chain, Even if Their Funds are Stashed Elsewhere

• Take a look at how to embed a flow that's compatible with ERC‑7683/OIF! So, here’s how it works: first off, a user signs a CrossChainOrder. Then, we get fillers stepping in to throw their hats in the ring and compete. Finally, the winner takes care of the gas fees and gets things rolling on your target chain. It's a pretty smooth process! Just a heads-up: your settlement will only release the user’s escrow if everything goes according to plan on the target’s side. (erc7683.org).

One awesome example of this is Across’ “web2-like” minting process. It lets users mint on Base while being able to pay from pretty much any chain they want. The coolest part? Users never had to mess around with a bridge UI at all. (across.to).

Looking to level up your game? Connect your solvers to Everclear! This way, you can have fills net across different chains, making it easier to manage your rebalancing and reducing those annoying quote spreads. It’s a smart move to simplify things a bit! (theblock.co).

Pattern D -- “Withdraw with gas included”

Goal: Steer Clear of the Classic “I Withdrew but Can’t Transact” Bug

We definitely want to avoid that frustrating situation where users pull out funds and then find themselves unable to make any transactions. Alright, let’s jump into how we can make that happen!

When you're all set to make a withdrawal, don’t forget to toss in a bit of native gas as a top-up for the destination wallet. It’ll help everything run smoothly! You can either use the Refuel tool for this or create your own native-token dripper that connects directly to the destination chain. It’s pretty cool how flexible it can be! Hey! If you're looking for more info, just click here. You'll find all the details you need! Hey there! So, if your wallet is compatible with EIP‑5792, guess what? You can actually merge the first action and gas sponsorship into one nifty call. Pretty convenient, right? No worries if you can't! You can just sponsor it using the ERC-4337 paymaster on your side. If you're looking for more details, check out this link. It's packed with useful info!

Build it: step‑by‑step delivery plan (8-12 weeks)

Phase 0 -- Scoping and policy

• Pick the ledger chains and assets you want to dive into: USDC, ETH, and your token v2. Alright, so here’s the plan: we need to create a trust policy and put some limits in place for each chain. For instance, we could say that “Stage 1+ Layer 2s have no restrictions,” while we’ll cap the others at a specific amount, let’s say $X. (medium.com).

Phase 1 -- USDC Fast Path (Weeks 1-3)

We’re starting things off by rolling out CCTP v2 on both the source and destination chains. We're planning to set up a cool hook that’ll not only credit the ledger but also print out receipts. First things first, we’re going to kick things off on about 2 or 3 chains. If you want to dive deeper into this, just check it out here. It's a great read!

Alright, so next on our agenda, we’re going to dive into the nitty-gritty of the migration plan from v1 to v2. We'll also get those deprecation timers plugged into our ops runbooks. Let's make sure everything's squared away! If you're looking to explore more about this topic, feel free to check out this link: blockchain.news. It's got some really interesting info!

Phase 2 -- Intent Router (Weeks 2-6)

Hey, let’s set up that ERC-7683/OIF adapter! And just a quick reminder: make sure to whitelist those fillers. Set up those SLAs, and if you're aiming for some real back-and-forth flow, definitely connect with Everclear for clearing. Take a look at the specs right here. You’ll find everything you need!

• We should also get the ledger escrow set up and do some proof-of-fill checks.

Phase 3 -- Your Token Canonicalization (Weeks 3-8)

Alright, first up, you gotta choose one of the options: CCT, OFT, ITS, or NTT. Once you've got your pick, go ahead and roll it out to your priority chains. Just remember to keep everything locked down tight with rate limits and admin keys, making sure to shard those keys securely. It’s all about keeping your stuff safe and sound! For more info, just head over here and check out the details!

Phase 4 -- UX polish + gas (Weeks 5-10)

• Start by launching those "gas included" withdrawals, then make sure to add EIP-5792 support to your front end. Finally, let's get the ball rolling with some initial actions using a paymaster. Hey, if you want to dive deeper into the details, just click here. It’s got all the info you need!

Phase 5 -- Controls and firewall (Weeks 6-12)

• Let’s get Glacis, or something similar, up and running so we can standardize the cross-chain routes and set a clear quorum policy. Hey, just a quick reminder to make sure you wire up the rate-limit telemetry for alerts. Don't want to miss anything important! Take a look at all the details here. You'll find everything you need!

---

Security and compliance guardrails that matter

Make sure to set limits on everything related to minting or unlocking as soon as it arrives. CCIP sets some lane and token-level limits, so don't forget to throw in those parallel application-level limits too. It's all about keeping things balanced! Oh, and don’t forget to set up an emergency “pause” feature for those big transfers if they go over a certain limit. It's super important for keeping everything secure! Take a look at this link: docs.chain.link. It’s worth checking out!

• Opt for multi-rail redundancy and make sure to create clear allowlists. With a router like Glacis, you can easily pick and choose the exact source contracts, chains, and GMPs you want to whitelist. Everything else? It’ll be blocked by default. It’s a great way to keep things secure while still having control over what you allow. When it comes to those important transfers, it might be a good idea to consider having a multi-bridge quorum in place. More info here: (docs.glacislabs.com).
• When it comes to handling fiat-related processes, it's best to stick with the standard rails. When you're handling USD transactions, definitely make CCTP v2 your first choice. Only switch to the older methods if there's a solid reason or policy guiding that decision. Hey, just a quick reminder to jot down the timeline for phasing out v1. We want to make sure that teams don’t inadvertently end up using those old endpoints. Thanks! Check it out: (circle.com). Try to stick with native token standards rather than using wrapped assets. When it comes to your own tokens and those from your key partners, it's a good idea to focus on OFT, NTT, ITS, and CCT. This way, you can maintain a consistent supply and avoid any risks that come with fragmentation. More details here: (docs.layerzero.network).
• Make sure your audits are on point and pay attention to those differences! Bridges and adapters can really vary a lot, so it’s a good idea to make it a routine to check those diffs before you roll anything out into production. The Across diff audit is a great example to look at for guidance! Learn more: (blog.openzeppelin.com). If you're getting into the Cosmos ecosystem, definitely check out ICS-27 Interchain Accounts! They're super handy for triggering remote actions using IBC. The latest IBC-Go now comes with support for unordered channels, which is fantastic for boosting parallelism. This feature can really make a difference when you're trying to improve performance! Get the scoop: (docs.cosmos.network).

KPIs and SLOs we recommend

• P95 credit time (USDC CCTP v2): We're looking at a quick turnaround time of 10 seconds or less once the source has finalized, and that's across all the supported lanes. Check it out here.
• P95 Credit Time (Intent Fills via 7683 Rails): Here’s the scoop--this one clocks in at 60 seconds or less. And hey, if you throw in a bit of friendly competition from other solvers, you might even nail down some quicker times. If you’re up for it, running your own solver can help you achieve even better results! If you want to know more, just check out erc7683.org!
• Fallback success on failed routes: We’re seeing an impressive success rate of at least 99% when it comes to finding alternative routes that work within the policy. And don’t worry, you’ll also get notifications if your policy ends up denying anything.
• Reconciled vs real-time credits: You can expect a flawless match (100%) the next day, thanks to those reliable cross-chain receipt IDs!
• Security SLOs: Just a heads up, we don’t have any credits unless there's a corresponding cross-chain receipt. Plus, we can’t unlock or mint anything that goes beyond what's allowed in our policy.

Deep dive: choosing the right token rail

• USDC: If you're looking for fast and dependable transfers, CCTP v2 has got you covered! With Hooks, you can kickstart your treasury and credit operations the moment your funds come in. It's all about making your life easier and streamlining those processes! Don't forget to stay updated on chain coverage! By early 2025, you should see support for Ethereum, Avalanche, and Base, with even more chains rolling out as the year goes on. So, keep your eyes peeled for those updates! (coindesk.com).
• Chainlink CCIP (CCT + Programmable Token Transfers): This feature is awesome if you're looking to move value while also sending along specific instructions. It’s like doing two things at once--imagine “transfer + stake” or “transfer + swap.” Perfect for those times when you don’t want to juggle multiple transactions! Plus, it comes with some pretty cool features like rate-limiting and DON-secured messaging to give you that extra layer of security. (docs.chain.link).
• LayerZero OFT: This one’s really starting to make waves in the DeFi world! It offers some cool features like burn/mint and lock/unlock functions, all thanks to its different adapters. If your partners already know about OFT, you’re in a great spot! You can check out more details here.
• Wormhole NTT: This is an awesome choice for environments with multiple VMs. It provides some straightforward operational modes, such as hub-and-spoke or burn-and-mint, making it easy to navigate and decide what works best for you. On top of that, it comes packed with some really useful tools right from the NTT CLI. (wormhole.com).
• Axelar ITS: This cool solution lets you maintain the same EVM address across various chains, which means your custom token logic stays intact. It also works really well with Squid for distribution, which makes things super convenient! (axelar.network).

Hey there! If you’re working with some really high-value tokens and are looking into exchange listings, you might want to consider giving xERC20 (EIP‑7281) a try. It can help with minting and burning your tokens in a rate-limited way across different bridges. Just a little tip to keep in mind! This way, you can make sure the blast radius for each rail stays under control. Once you have that set up, you can go ahead and send it through an aggregator or a firewall. (cointelegraph.com).

Example end‑to‑end flows

1. You can get your USDC on Solana credited to your Base account in just a few seconds! It’s super quick and easy. Alright, so first things first, we spot the SPL‑USDC deposit and then we jump right into the CCTP v2 transfer. Once it’s on Base, Hook jumps in and calls credit(); and just like that, we spit out a receipt with the CCTP message ID. Pretty cool, right? You can check your balance in just a few seconds! It's super quick and easy. (circle.com).
2. Your token (just launched) → It's going to be available across multiple chains!

• Go ahead and set up those CCT or OFT contracts across various chains, and don’t forget to put some rate limits in place! So, when users make their deposits on Chain A, your router does a great job of managing those programmable transfers. It smoothly wraps everything up so that their deposits get finalized and credited on Chain B--all in a single transaction with a handy “transfer+credit” combo. Super efficient, right? Take a look at this link: docs.chain.link. You’ll find some pretty cool info there!

1. Checkout with “Pay from anywhere” option. So, here’s how it works: you start by signing an ERC-7683 order, and then a solver steps in to handle everything on whatever blockchain you’ve decided to use. Pretty straightforward! As soon as it goes through successfully, the ledger gets updated. Everclear helps keep everything running smoothly throughout the day, so you don’t have to constantly juggle your capital. (erc7683.org).
2. Move your funds to a new chain, and don’t worry - the gas fees are covered! The orchestrator finds the best route and throws in a bit of native token refuel for the destination. If your wallet supports EIP-5792, it’ll handle everything in batches. If it doesn’t, no worries! It’ll just start things off by sponsoring the first action using an ERC-4337 paymaster. (docs.bungee.exchange).

Emerging best practices we’re advising enterprise teams

• Think about using "programmable settlement" instead of just sending a message and then doing something later. It’s a more streamlined approach! With CCIP's Programmable Token Transfers, or CCTP v2 Hooks, you can get your settlements to do some cool stuff the moment they land. Whether it’s crediting, staking, or sweeping fees, you’ve got options to make it happen right away! This makes everything easier since there are fewer things to juggle, and it really helps avoid those frustrating reconciliation headaches. Take a look at this: (blog.chain.link). It’s worth checking out!

Hey, how about we make cross-chain intents a bit more uniform by using ERC-7683? This way gives you more choices and helps you steer clear of being tied down to just one vendor. Plus, by adopting OIF, you won't have to keep rebuilding the same infrastructure over and over again. That's a real time-saver! Learn more at (erc7683.org).

• Right from the start, go for a multi-rail firewall. It's a smart move! If you combine Axelar, Wormhole, LayerZero, CCIP, and Hyperlane through a policy engine like Glacis, you can easily adjust your route policy whenever you need to--no need to redeploy your app logic each time. It’s a really handy way to stay flexible! Want to dive deeper? Check it out here: docs.glacislabs.com!
• Don't forget to net your flows! When you’re increasing your deposits, that rebalancing tax can really start to pile up! Using a clearing layer like Everclear can really help reduce that liquidity churn and make for a way smoother experience for users. It's all about keeping things flowing seamlessly! Check it out for more info: (theblock.co).

Consider your L2 security measures as part of how you determine your credit limit. Alright, so here’s the deal: use the L2BEAT stages along with DA assessments to figure out your caps for each chain. Make sure everything is looking solid with your proofs and bridges before you hit the go-ahead according to your policy. Just take your time to get everything in order! More details at (medium.com).

The bottom line

"Bridgeless deposits" might seem like a fancy term at first, but really, it's all about using smart routing on the right rails. When you mix that with programmable settlement and strong policy controls, it all comes together nicely! With CCTP v2, ERC-7683/OIF, and all those cool features like CCIP Programmable Token Transfers, OFT/NTT/ITS token standards, and even permissionless interoperability (shoutout to Hyperlane for that!), you can easily handle Any-Chain In and Any-Chain Out accounts. It's like having that smooth Web2 experience, but don’t worry--you’re still keeping things secure and transparent, just the way your auditors would approve of. Pretty neat, right? (circle.com).

If you need a reliable reference implementation or a tailored integration plan that aligns with your chain mix and risk policy, 7Block Labs is here to help like a specialized strike team ready to tackle the challenge! They’ll have the USDC fast path up and running in just a few weeks, and you can expect the full multi-rail setup to be ready for you within the next three months. Pretty exciting stuff!
