Why TON is different for startups and enterprises in 2025

• Native distribution: Telegram’s Mini Apps (TMAs) are now running inside Telegram with some cool new updates in version 2.0. We’re talking full-screen support, homescreen pinning, tapping into device capabilities, and subscriptions using Stars. For growth teams, it’s like having a mobile super-app without the hassle of App Store installations. Check it out here: (core.telegram.org)
• Monetization that actually settles:
  • There’s a sweet 50% ad-revenue share for broadcast channels, and it’s all settled in Toncoin on TON. For brands and media outlets, this is a straightforward on-chain payout system tied right into content distribution. More info can be found here: (coindesk.com)
  • With “Telegram Stars,” TMAs can sell digital goods using standard in-app purchases on iOS and Android. Then, you can effortlessly convert those Stars to Toncoin via Fragment. This helps dodge the usual mobile policy headaches while keeping things crypto-native on the payout side. Learn more at: (finance.yahoo.com)
  • USDT made its debut on TON in April 2024 and has been growing like crazy--your app can tag prices in dollars while operating on TON. Dive deeper here: (theblock.co)
• Proven performance: TON has shown it can handle over 100,000 TPS in a public, audited stress test (thanks to dynamic sharding), which really highlights its potential for consumer-scale apps. While it’s smart to think of this as capacity rather than a guaranteed production TPS, it definitely sends a positive signal. Check it out here: (chainwire.org)

The “TON Developers Program” landscape: who funds what (and how to tap it)

You’re going to come across a bunch of overlapping initiatives; here's a breakdown of how they all connect, along with some practical timelines and ranges:

• TON Accelerator Program (TAP): You can snag up to $25M through the TONcoin Fund. They typically write checks ranging from $50k to $250k and provide mentorship along with business development support. This is a great opportunity if your team has an MVP and a solid TON-native angle--think DeFi, TMAs, or infrastructure. Check it out here.
• The Open League (TOL): This program is all about seasonal liquidity and user-growth incentives. In early 2024, they’re piloting an initiative that will distribute up to 1M TON. Later on, there will be DeFi Grants available for up to $520k per team, plus a dedicated 5M TON incentive program aimed at DEXs and liquid staking. It’s smart to align your launch with a TOL season to grab some customer acquisition cost (CAC) subsidies. More details can be found here.
• Topical incentives: Some cool opportunities like EVAA offering a 100k TON program and Storm Trade also rolling out 100k TON. Plus, there are periodic competitions in collaboration with partners like Jupiter for projects focused on aggregation and liquidity. These are fantastic for targeted product sprints where you can measure things like total value locked (TVL) and volume KPIs. Learn more here.
• Hackathons and Bootcamps: Get involved in the TON HackerHouse, where there are $1M in prizes up for grabs! They also have dedicated TON tracks at major events like ETH Belgrade. These are perfect for rapid prototyping and getting to know the ecosystem better. More info is available here.
• Grants in 2025: Keep an eye out for “Champion Grants,” which are aimed at high-impact teams that are already making strides. If you've got traction, this is definitely the opportunity you want to pursue. Dive deeper into it here.

Tip: At 7Block Labs, when we submit an application for you, we take the time to align your milestones with the scoring criteria of each program--like user growth, DeFi total value locked (TVL), and integration depth. Plus, we time your TMA launch to coincide with a TOL window, ensuring that you get the most out of those crucial first 30-60 days with some nice incentive multipliers.

Architecture choices that matter on TON

• Sharding and message routing: TON embraces this cool "infinite sharding paradigm" where you have per-account virtual chains that are grouped into shards. Plus, they ensure cross-shard delivery is on point through Masterchain queues. So, when you're designing contracts, make sure to account for asynchronous messages and bounces. Check it out here: (docs.ton.org)
• Storage fees and account lifecycle: Contracts will rack up storage rent, and if you don’t pay up, things can get dicey. An account might freeze if it has over 0.1 TON in debt, or it could even get deleted if it hits over 1 TON in debt and has a zero balance. Just a heads-up--your operational budget should cover hot addresses that keep state, like order books and vesting contracts. More details here: (beta-docs.ton.org)
• Fee model: When it comes to transaction fees, you’ll be looking at a total fee that includes storage, import, compute, action, and forwarding. If you're keen on keeping costs in check, try to minimize cell/bit usage in your state, steer clear of unnecessary outbound messages, and consider batching your operations. Find out more: (beta-docs.ton.org)
• Address handling: It's a good idea to use bounceable addresses when sending to smart contract destinations--this way, you’re safe if something goes wrong. For funding uninitialized accounts, stick to non-bounceable addresses. Wallets will automatically toggle bounce flags based on account status, so make sure your custom senders mimic that logic. Dive deeper here: (docs.ton.org)

Production pattern we're using:

• We keep high-churn states off-chain, using Ton Storage or our app database, and just use on-chain anchors. This way, we only pay rent for the stuff that really matters. Check out more here!
• We gather value in a treasury contract and fund temporary operational contracts right when we need them. This helps minimize our rent exposure.

The modern TON dev stack (2025)

Languages and Compilers

• Tolk 1.0: This is our new main language, and it’s way more expressive than FunC, specifically crafted for TON’s actor model. If you're diving into development in 2025, we recommend using Tolk for your core contracts. Check it out here.
• Tact: Think of this as a TypeScript-like DSL that’s been audited by Trail of Bits. It’s perfect for getting up to speed quickly and handling complex app logic. By early 2025, around a third of the unique contracts on the mainnet were created using Tact. Want to learn more? Click here.
• FunC: This one's a reliable low-level language that’s been put through the wringer. It’s still hanging around for reference standards.

Tooling:

• Blueprint: You can kickstart your projects with npm create ton@latest. It sets up a sandbox chain, runs your tests, and handles deployments through TON Connect or deeplink. This is our go-to method for getting repos up and running. Check out the details here.
• TON Connect 2.0: This is all about the wallet-dApp handshake with bridge servers, SDKs, and some handy guidance for backend auth. It's a must-have for TMA and wallet flows. Dive into the specifics on GitHub.
• Client libraries and APIs:
  • @ton/core: This one's actively maintained and great for low-level primitives. You can find it on npm.
  • TonAPI: Offers REST, emulation, and streaming; Toncenter: provides JSON-RPC; and TONX: combines Supernode and SDK for production indexers with higher requests per second (RPS). We like to mix up our providers to ensure redundancy. Learn more about them here.

Quick Start Guide

• Scaffold: Run npm create ton@latest and then pick Tolk or Tact to generate your tests and deployment scripts.
• Local Test: Check out Blueprint Sandbox for fast end-to-end unit tests that run in-process. It really speeds things up! You can find more information here.

Telegram‑native product patterns that work

1. Payments and Pricing:

• Digital Goods: For things like subscriptions, boosts, and game items, you’ll want to use Stars for IAP compliance. Creators can easily convert Stars to Toncoin through Fragment, which has really helped speed up iOS review times and make SKU logic more consistent across platforms. Check out more about it here.
• Crypto Settlement: Let’s make things easier by enabling USDT on TON for dollar pricing, which cuts down on any exchange headaches. For those little fees and internal incentives, it’s best to stick with Toncoin as the default. More details can be found here.
• Merchant Checkout: With Wallet Pay, bots and TMAs can accept BTC, USDT, and TON right within Telegram. Just make sure to align your usage with your local regulations and policies. You can read more about it here.

2) Distribution and growth:

• TMAs now come packed with full-screen modes, device APIs, subscriptions, and even homescreen pinning--basically, you can treat them like top-notch mobile apps that you access through deep links. When you mix this with Telegram Ads and the sweet 50% channel revenue share (paid in TON) for creator partnerships, you’ve got a winning formula. (theverge.com)

1. Wallet Experiences:

• TON Space is a self-custody wallet that's built right into Telegram’s Wallet. Just a heads-up: during its 2023 rollout, it didn’t include the U.S. So, if you're planning to reach U.S. users, you might want to think about adding some geo-based feature flags. You can check out more details here.

---

Tokenization and standards you’ll actually use

• Jettons (which are fungible) and NFTs on TON stick to TEP‑64 metadata and TEP‑62/NFT patterns. This makes it super easy to predict how marketplaces and wallets will support them, thanks to the handy reference implementations. You can save on-chain space by using semi‑chain metadata to keep images off the chain while still having the name and symbol fields on-chain. Check it out here: (beta-docs.ton.org).
• With TON DNS and Sites, you get human-friendly .ton names that can point to wallets or services. Plus, TON Sites and Storage give you reliable hosting and let you pin app content. This feature is great for creating those cool vanity addresses and ensuring your content’s provenance is solid. Dive into the details here: (docs.ton.org).
• When it comes to DEX and staking, STON.fi and DeDust are really leading the charge in liquidity. Liquid staking through Tonstakers/Bemo (tsTON/bmTON) fits perfectly into DeFi programs like TOL. We’re working on combining LP and staking strategies to boost TVL. You can find more info here: (docs.ston.fi).
• For wallet standards, the newer W5 (also called V5) has your back with multi-send and gasless features in compatible wallets. If you're generating wallets programmatically, it's important to keep an eye on versioning. More about that here: (tonkeeper.helpscoutdocs.com).

Security, compliance, and ops: the stuff teams overlook

• Storage rent budgeting: Keep an eye on contract state growth and automatically top up accounts before hitting freeze thresholds. We've added rent alerts based on config param 18 and account stats. Check it out here.
• Bounce logic: Make sure to always manage bounced messages; never run the original payloads after a bounce. This helps avoid those sneaky replay or logic errors in asynchronous flows. You can read more about it here.
• Node vs. API: If you’re planning to run an archive node for analytics or explorers, be ready for some hefty hardware requirements--think 16 cores, 128 GB RAM, and around 12-14 TB of SSD space. For most applications, it’s better to start with TonAPI, Toncenter, or TONX, and then consider adding light or full nodes when necessary. More details are available here.
• TMA impersonation risk: When shipping, always use the official bot handles. It’s super important to educate users about not installing APKs or using clones (there have been some malware impersonations of popular games). We’ve incorporated in-app provenance banners and good link hygiene to help out. Check out the details here.
• U.S. distribution: Since TON Space initially left out U.S. users, make sure to have region-aware toggles for wallet features and to align Wallet Pay usage with local policies. Get the scoop here.

1) Quick “Dollar” Checkout in a TMA

• Here's how it works: When a user hits the Buy button, if they're purchasing a digital item on iOS or Android, we'll charge them using Stars. The server keeps a count of the Stars, and once it hits a certain limit, it automatically converts those to Toncoin through Fragment for the treasury. For non-digital items or web purchases, we'll show them Wallet Pay using the USDT-TON rail. This way, we're neatly separating policy-related stuff from the on-chain settlement. (finance.yahoo.com)

2) DeFi Launch with Incentives

• Team up your token with USDT‑TON pools on STON.fi, allocate your LP in the farms, and don’t forget to apply for an Open League DeFi grant. Aim for clear, measurable goals (like pool depth, 30‑day volume, and LST integrations) to move up to those higher tiers. Check out more details here!

3) Risk-Aware Wallet Funding

• When you're rolling out new user wallets or contracts on a larger scale, it's a smart move to kick things off with a small non-bounceable message first. This way, you can get everything initialized without risking a huge loss if something goes wrong during deployment. Make sure to stick to non-bounceable for uninitialized wallets and only switch to bounceable after activation. Check out the details here.

1. Dev scaffolding and testing

• Kick things off with npm create ton@latest and choose either Tolk or Tact. Then, go ahead and write some unit tests to check exit codes and gas usage in the Blueprint Sandbox. Don’t forget to integrate TON Connect for wallet authentication in your TMA. You can find more info here.

Emerging best practices we recommend

• Languages: Go for Tolk when you're setting up new core contracts; Tact is your buddy for speedy shipping or if you need to match team skills. And don’t forget those FunC snippets for those high-performance bits. (blog.ton.org)
• Monetization strategy:
  • In-app stuff: Stars can be swapped for Toncoin through Fragment.
  • On-chain DeFi and payouts: Think Toncoin + USDT‑TON pairs.
  • Deals with creators: Use Ads payouts in TON to set up revenue sharing with channel owners. (finance.yahoo.com)
• Infra: Use multiple indexers (TonAPI + Toncenter + TONX) and keep an eye on health checks; only spin up your own nodes if you really need that deterministic indexing or have data locality needs. (docs.tonapi.io)
• Compliance and regions: You can toggle wallets and payouts based on regions (like the U.S. and others). For merchants, Wallet Pay can work, but double-check the local regulations first. (techcrunch.com)
• Growth loops: The TMA virality, Stars promotions, and reinvesting in channel Ads create a nice closed loop within Telegram. This is basically a hands-on playbook for a “Web3 super-app” that you can kick off right now. (theverge.com)

90‑day delivery blueprint (what we do at 7Block Labs)

• Days 0-14: Product and Compliance Design
  • First things first, we need to choose our flows: decide between Stars, Wallet Pay, or using USDT on TON, and figure out those geo flags.
  • If it fits, let’s draft up some token economics, whether it's Jetton or NFT based on TEP‑64/62. Check it out here: (beta-docs.ton.org)
• Days 15-35: MVP Build
  • Time to get our hands dirty! We’ll scaffold contracts using Tolk/Tact with Blueprint, connect with TON Connect, and set up our TonAPI/Toncenter/TONX providers. Plus, we’ll build the TMA UI using the Telegram WebApps SDK. More info here: (docs.ton.org)
• Days 36-55: Liquidity and Payments
  • Let’s get listed on the STON.fi pool with a USDT pair, and if we need LST utility, we can integrate with Tonstakers/Bemo. Also, we should set up Wallet Pay if it’s on our radar. Check it out here: (docs.ston.fi)
• Days 56-75: Incentives and Partnerships
  • Now’s the time to apply for the Open League/DeFi programs and coordinate some co-marketing with channel owners--plus, we’ll need to budget for ads using TON. For more details, have a look here: (blog.ton.org)
• Days 76-90: Scale and Ops
  • Finally, we’ll add in some rent and fee monitors, load test those sharded message patterns, and come up with a plan for archive data or expanding API redundancy. Don’t forget a security review to handle bounce management, exit codes, and upgrade paths. More info here: (docs.ton.org)

When to run nodes vs. buying infra

• Kick things off with APIs like TonAPI, Toncenter, or TONX. There's really no need to run a full or archive node unless you absolutely need it for:
  • deterministic replays,
  • sub‑second internal analytics,
  • or data residency/compliance.
    If you do go for an archive node, keep in mind that you'll need some serious specs--think 16 cores, 128 GB of RAM, and around 12-14 TB of SSD. So, make sure to budget for both the hardware and the SRE. (docs.ton.org)

---

Key gotchas (and how we mitigate them)

• Unpaid storage fees are putting a hold on crucial contracts: let’s set up automated refills based on param‑18 pricing and the size of each contract; also, we should aggressively shrink the state. (beta-docs.ton.org)
• Funds ending up in uninitialized addresses: we need to stick to the bounceable/non-bounceable rules in our SDKs and send a small “init” transfer before diving into bigger ones. (docs.ton.org)
• Policy hiccups on iOS/Android: let’s monetize digital goods using Stars instead of direct crypto, and convert to TON afterwards. (finance.yahoo.com)
• Avoiding those lofty TPS promises: we should aim for realistic app-level throughput; remember, that 100k+ TPS feat was just a controlled testnet stress test, not something we can promise in production. (chainwire.org)
