Blockchain Security Audit vs Smart Contract Audit: What’s the Difference?
It's common for startup and enterprise teams to confuse "smart contract audits" with "blockchain security audits," but here's the scoop: they’re not the same thing at all. This guide gives you the lowdown on what you need to know, covering everything from the scope and outputs to the factors you should consider when making decisions. It’s all updated for the 2025 scene, featuring new stuff like EIP‑4844 blobs, rollup “training wheels,” and some cool tweaks for account abstraction. With this info, you’ll be able to choose the best engagement option precisely when it counts the most!
When it comes to a blockchain security audit, it's all about getting a thorough look at everything happening both on-chain and off-chain. This means checking out everything from the infrastructure and keys to the bridges, rollups, and even the governance. It's a comprehensive review that covers all the bases! On the other hand, a smart contract audit really focuses on the code itself and how the protocol works. As we look ahead to 2024-2025, it’s becoming pretty clear that a lot of the losses we’re facing are linked to compromised infrastructure and keys. So, basically, a lot of teams really need to handle both audits, and it’s super important to do them in the right order!
TL;DR for decision‑makers
- Consider getting a Smart Contract Audit (SCA) to iron out any annoying code issues, double-check those protocol invariants, and ensure your upgrade paths are really dependable.
- Consider getting a Blockchain Security Audit (BSA) to really understand the complete range of risks from start to finish. You’ve got a whole range of stuff covered here, from keys like MPC and HSM to nodes and RPC. We’re also talking about those L2 and bridge assumptions, governance with timelocks, and keeping an eye on monitoring and incident response. Plus, there’s the whole MEV exposure aspect and making sure data is available. It’s a lot to wrap your head around, but it all plays a crucial role! In 2024, attackers managed to pull off around $2 million. We're talking about $2 billion in stolen funds, and a good portion of that came from attacks on infrastructure. You know, things like key and front-end attacks really did some serious damage here. So, based on different datasets, we're looking at somewhere between 60% and 80%. Hey, just a quick reminder--don’t limit yourself to just code reviews! Check out this link for some more insights: chainalysis.com. You won’t want to miss it!
Why the distinction matters more in 2025
Ethereum's Dencun (you might know it as EIP-4844) is really making waves! It introduces blob transactions, which are pretty exciting, along with a brand-new blob-gas market. Plus, it comes with KZG commitments that rely on a trusted setup. It's definitely something to keep an eye on! It's a win when it comes to fees, but it definitely introduces a new layer of complexity that you'll want to watch closely. Take a look at this: eips.ethereum.org. It's worth checking out! Hey! So, just a heads up--Optimism's OP Mainnet rolled out its permissionless fault proofs on June 10, 2024. Exciting stuff! With this update, OP Stack chains are stepping into Stage 1 of decentralization. This means it’s time to reassess how much trust you place in withdrawals and make sure to double-check those assumptions during your audits. It's all about staying on top of things! If you're looking for more info, check it out here: (docs.optimism.io). It's got all the details you need! Hey! Just a heads up - you can now keep an eye on how rollups are maturing with L2BEAT’s Stages feature, which goes from 0 to 2. It’s a neat way to follow the progress! Your risk really boils down to how your Layer 2 setup is doing, the reliability of its Security Council, and the upgrade timelines they've got in place. If you’re looking for more info, check this out: l2beat.com. You’ll find what you need over there! So, there's this new proposal for account abstraction, you know, EIP‑7702 (it's the one that people are talking about for the Pectra era), and it's really shaking things up when it comes to how externally owned accounts (EOAs) work. This could seriously throw a wrench in some of those tx.origin assumptions that a lot of people have been relying on. Auditors really have to take these edge cases into account when they’re running their tests. Dive deeper here: (eips.ethereum.org).

If you want to dive deeper, you can find all the details here.
Blockchain Security Audit (BSA)
Let's take a step back and look at these key areas from a broader perspective:
- Let’s talk about key management! This includes all the stuff like custody, wallets, and signers. Plus, I’ll give you a peek into how our node and RPC infrastructure works, along with our CI/CD processes. Oh, and I'll also cover how we keep an eye on everything and handle any incidents that pop up. Let's dive into some key points about Layer 2s, bridges, and data availability layers. We’ll also chat about sequencer roles, how we handle fault and validity proofs, and the importance of exit windows. For more info, swing by l2beat.com! It's a great resource if you're looking to dive deeper into the details. Let’s talk about governance stuff. This includes things like multisigs, Security Councils, and how we handle upgrades with those handy timelocks. Plus, we need to think about ways to keep end-users safe from MEV. If you want to explore this further, just head over to openzeppelin.com. There’s a ton of great info waiting for you there!
Main Goal: We’re aiming to create a handy risk register along with a remediation plan. This will include strategies for fixing issues on the blockchain itself as well as some off-chain controls to keep everything secure.
2024-2025 breach data: why “code‑only” is not enough
So, in 2024, hacks ended up costing about $2.
We're talking about a whopping 2 billion in losses, and a big chunk of these incidents are linked to some serious infrastructure problems--things like compromised private keys or seed phrases, and even front-end hijacking. It's a pretty big deal!
So, both TRM and Chainalysis are highlighting that infrastructure attacks are really the key players when it comes to these losses.
In the early part of 2025, a staggering 80% of all stolen funds came from these kinds of attacks. Can you believe that? It really highlights how big of a problem this is becoming.
(chainalysis.com).
So, here's the deal: even if your contract code is perfect and squeaky clean, it's still vulnerable to a few sneaky risks. We're talking about stuff like hacked deployer or admin keys, dodgy upgrades, DNS hijacking, or even compromised RPC front-ends. It's a bit of a minefield out there! It's super important to make sure your audit scope considers these risks.
Scope: what each audit type actually checks
Smart Contract Audit: concrete scope checklist
- Logic/Invariant correctness: We're diving into the math behind ERC-20, ERC-721, and AMMs to ensure everything's on point. This means checking that there's enough liquidity, all the fees are in check, and that those important invariants are staying solid. Don't worry, we've got everything sorted out with fuzzing and invariant suites--big thanks to Foundry for that! Plus, we've also incorporated some important formal rules from Certora to keep things on track. (foundry-book.zksync.io).
- What we cover: We’ve got a solid handle on SWC categories. We're addressing issues like reentrancy, authentication missteps, and unchecked calls, all while making sure we stay in the loop on SCSVS controls. (github.com).
- Upgrades: We’re totally on top of our upgrade game! We’ve nailed down our strategy, which involves choosing the best proxy patterns, keeping an eye on any changes to our storage layout, and making sure we’ve got UUPS _authorizeUpgrade access all sorted. Plus, we’re mapping out our timelock strategy, and we’ve got solid rollback and rehearsal plans in place, just to be safe. (docs.openzeppelin.com).
- External dependencies: We're on top of things like oracles, L2 messaging, router approvals, and token permit flows. And just to be safe, we do some failure-mode tests to sniff out any potential issues before they become real headaches.
- Gas/DoS limits: We’ve put some solid limits in place for loops to keep everything running smoothly. We've also taken measures to protect against potential griefing issues, added reentrancy guards, and established our emergency pause protocols just in case.
- Chain‑specific:
- Ethereum AA readiness: We're keeping a close eye on those tx.origin anti-patterns, particularly when it comes to EIP-7702-style flows. (eips.ethereum.org).
- Solana programs: Hey, just a quick tip! If you’re aiming for immutability, don’t forget to properly remove the upgrade authority. It’s an important step! (solana.com).
Tools You Might Encounter
Let’s take a peek at some of the tools you’ll probably run into:
- Foundry: This is a great tool for fuzzing and checking invariants.
- Slither
- Echidna
- Manticore/Mythril
If you’re in the mood to explore a bit, you should definitely take a look at Certora Prover. It’s perfect for digging into those high-impact properties! If you want to explore Foundry a bit more, you can check it out here.
Blockchain Security Audit: concrete scope checklist
- Managing Keys and Keeping Them Safe.
- You can either use signers in HSMs that meet FIPS 140-3 Level 3 standards or opt for MPC with some threshold policies in place. Don't forget to set up some procedures for rotation, quorum, and emergency revocation. It's really important to have those in place! If you're interested, you can find all the details right here. Take a look!
- Node/RPC and Mempool Overview.
- Set up a multi-provider RPC system that includes health checks to keep everything running smoothly, plus make sure you have reliable fallbacks in place. It’s all about ensuring you stay covered, no matter what happens! Using a private-order flow RPC like Flashbots Protect is a smart move if you want to cut down on sandwiching. If you want to dive deeper into this, check it out here.
- Helping Users with MEV Issues. Hey, have you considered looking into private routing or maybe even batch auctions? You could check out options like CoW Protocol or UniswapX--they’re pretty interesting! Also, don't forget to check out some rebate-program RPCs like MEV Blocker. They could be really helpful! If you're looking for more details, just check this out here.
- L2/Bridge Assumptions
Hey! Just a quick reminder to take a look at the rollup "Stage" (0/1/2) first. Don’t forget to check on the proof systems--make sure they’re present and that the permissions are all set. Also, keep an eye on the exit windows, the powers of the Security Council, and verify if the DA bridge can be upgraded. It’s important stuff to keep in mind! If you’re looking for more information, you can check it out here. - Solana/Cosmos Operational Posture
For Solana, take a look at how the BPF upgradeable loader is being used and make sure to check on the custody or revocation of the upgrade authority. Make sure you’ve got a validator KMS set up with either a YubiHSM or a Ledger, and don’t forget to enable double-sign protection! It’s a smart move to keep everything secure. Learn more here. - Monitoring/IR
Alright, so first things first--let's get those Forta detection bots set up for on-chain monitoring. Once we’ve got that rolling, we should definitely consider adding some operational alerting and automation. You might want to check out Defender Monitor or something similar for that. It’ll make everything run smoother! Want to see how it all works? Check it out here!
1) Ethereum + L2 rollup dApp (OP Stack or Base)
Hey, just a quick heads up--don't forget to double-check that the fault proofs are actually live on the target chain! The OP Mainnet officially launched its permissionless proofs on June 10, 2024. Exciting times ahead! Hey, just a heads-up! If you're planning on using permissioned withdrawals or setting up a Security Council, that’s a pretty significant trust assumption. Make sure to jot it down in your risk register and user documentation so everyone’s on the same page. If you're curious to dive deeper into the topic, feel free to check it out here. It's packed with some great info!
Hey there! Just a quick reminder for when you're working on policy with L2BEAT's Stages: make sure that for Stage 1 systems, any exits for non-Council upgrades should stick around for at least 7 days. It's a good rule of thumb to keep things smooth! In Stage 2, make sure you’ve got permissionless proving set up, and don’t forget about those 30-day exits. They’re key! Don't forget to check your governance contracts and timelocks to make sure they meet these requirements! It's a good idea to stay on top of this stuff. If you want to dive deeper into the details, just check this link out here. You'll find everything you need!
Hey there! Just a quick reminder: if your rollup is sending blobs to L1 thanks to EIP-4844, make sure you include those blob-gas trend dashboards and some near-DA-outage runbooks too. It’ll help keep everything running smoothly! Hey, just wanted to give you a quick reminder that blob parameters and KZG commitments aren’t the same as calldata. Just something to keep in mind! If you want to dive into the details, just click here. You’ll find everything you need!
2) Upgradable EVM protocol migrating to UUPS
Don't forget to set up multi-signature and a timelock for those upgrade rights! It's super important for keeping everything secure. You really need to make sure that the storage layout works with CI, and OpenZeppelin Upgrades can help with that! Oh, and make sure you run some clear tests for downgrades and rollbacks too! It's super important not to skip that step. If you’re looking for more details, you can check it out here: docs.openzeppelin.com.
- Test out the upgrade path by running a red team exercise. How about pulling off a clever implementation swap? You’ll want to show that your defenses are rock solid--maybe by demonstrating that timelock delay right on-chain. Make sure to jot down a "break-glass" plan just in case you need it. Make sure you’re keeping tabs on the admin key custody by using HSM/MPC with a quorum setup. It’s a good idea to run through some scenarios to see what would happen if a signer goes missing or needs to be swapped out. If you’re looking for more info, take a look at this link: NIST Cryptographic Module Validation Program. It’s got all the details you need!
3) Solana program launch
If your program needs to stay unchanged, don’t forget to revoke the upgrade authority right after you deploy it. Also, make sure to jot down all the details on-chain so you have a clear record. Hey, just a heads up--most programs are set to be upgradable by default when you’re using the BPF upgradeable loader. (solana.com).
- On the other hand, if you want to keep that upgrade option available, it's a good idea to strengthen your authority. You might want to consider using something like HSM or a ledger-backed custody system. Plus, setting up a two-person control system can really help. Just make sure you have a detailed runbook ready and practice going through it together. (docs.cosmos.network).
4) Cosmos app‑chain integrating IBC + CosmWasm
You can think of IBC as being trust-minimized instead of totally trustless. If a counterparty’s validator set exceeds the BFT fault threshold, there's a chance the Tendermint light client could be deceived. Just a heads up: even though misbehavior proofs can help put the brakes on a client, they’re not a cure-all for a full-on capture situation. That’s why it's a good idea to have rate limits and a solid incident response plan ready to go. (ibc.cosmos.network).
- So, if you're using validators along with KMS tools like YubiHSM or the Ledger app, it's a good idea to set them up on different machines. Also, don’t forget to put double-sign protection in place to keep everything secure! Hey, just a quick reminder to make sure you check for ed25519 support as well! You can find more info here. Happy exploring!
Emerging best practices to add to your 2025 playbook
- Private Orderflow + MEV Rebates: Whenever it makes sense, be sure to send user transactions through Flashbots Protect or MEV Blocker. It’s a smart move! In 2024, MEV Blocker announced that it had handed out an impressive 4,079 ETH in user rebates! Honestly, this makes it a prime choice for anyone trading in retail. Take a look at it here: docs.flashbots.net. It’s got some great info!
- Batch Auctions vs. FCFS: So, if we use CoW Protocol's fair combinatorial batch auctions alongside UniswapX’s auction-style method, we can really lower the risk of those pesky sandwich attacks. This setup is a lot safer than what you’d find in traditional public mempools. You might want to consider adding these platforms to the routing logic. It could really improve things! More details here: docs.cow.fi.
- Storage-Aware Invariant Fuzzing: Make sure to enable Foundry's storage layout output--this little tweak can really boost the way you sample your invariant inputs! This gives you the ability to run long-term campaigns using afterInvariant hooks, which are super useful for wrapping up positions and making sure everything's on track. Check it out here: foundry-book.zksync.io. You'll find some really interesting stuff!
- Formal Verification for Important Rules: It’s super important to outline and confirm key rules, such as avoiding balance underflow, keeping the supply consistent, and ensuring that things accumulate in a steady way, all with the help of Certora Prover. Make sure to add this into your CI with those rule-level checks in place, okay? It’s super important! Hey, if you’re looking for the info you need, just check this out: docs.certora.com. It's got everything you’re searching for!
- Rollup Stage Gates: Make sure you set clear criteria for going live that tie in with the L2BEAT Stage 1/2 requirements. This means you should have permissionless proofs all set up and aim for at least a 7 or 30-day exit window. If you want to dive deeper into this topic, check it out over at l2beat.com! They’ve got some great info waiting for you there.
- Blob-Era Observability: Make sure to create specific dashboards to keep an eye on blob gas usage and the health of data availability. Oh, and don’t forget to add alerts for any potential issues with blob-sidecar propagation that could come up after Dencun. It’s always better to stay ahead of those! Check out this link for more info: eips.ethereum.org. It’s got some great insights!
Deliverables and evidence you should demand
- For SCA
So, you're going to want to put together a threat model and then link what you discover to the SWC, SCSVS, and EthTrust controls. It’s all about making those connections clear! Don't forget to throw in some proof of concepts or demos of the exploits, along with test artifacts from Foundry that we can reproduce. That way, we’ll have some solid examples to work with! Check it out here!. - Make sure to add an invariant test suite and throw in a few fuzz harnesses to your repo! If you're looking to level up your game, you might want to think about incorporating some formal specs for those important invariants with Certora CVL. It could really make a difference! More info here!. Hey, just a quick reminder to check out the upgrade path! Make sure you look into the on-chain governance and those timelock rehearsals too. It's definitely worth your time! Check out this link for some handy tips and guidance! You can find it here. Enjoy!
- For BSA
Here's a useful key-lifecycle playbook that aligns perfectly with FIPS 140-3. It includes evidence for signer HSM/MPC and even some rotation drills to keep things running smoothly. Feel free to take a look at it here! Hey there! So, we’ve got the results from the RPC resilience test, and we’ve also put together an MEV policy. This covers things like our default private routing settings and the relays and builders we’re backing. Find the details here. I've put together a risk matrix for L2/bridge that lines up perfectly with the stages from L2BEAT. This includes everything from the current status of the proof system to details on exit windows and the powers of the Security Council. Pretty handy, right? Check it out here. - Keeping an eye on the runbooks that come with Forta and Defender setups. This includes checking out alerts, setting up auto-responses, and figuring out escalation paths. Dive into it here.
Red flags we still find (and how to fix them fast)
Hey everyone! Great news - admins can now easily upgrade UUPS proxies with just one key! Just remember to secure it with a Safe multisig and a timelock. And don’t forget to double-check those _authorizeUpgrade guards while you’re at it! (docs.openzeppelin.com). Hey, if you’re working with private order flow routing, it might be a good idea to enable Flashbots Protect or check out the MEV Blocker. Just a little tip! Oh, and don’t forget to keep an eye on those sandwich prices, both before and after! (docs.flashbots.net). So, there’s a bit of confusion when it comes to L2 dependencies and proof systems. It’s really helpful to keep track of when proofs are ready, sketch out those exit windows, and maybe put some caps or pauses in place based on the different stages of upgrades. It's all about keeping things organized and clear! (docs.optimism.io). Oops! Looks like the Solana program got left in an upgradeable state by accident. Don't forget to revoke that authority and save a record of the transaction for your own peace of mind! (solana.com).
What 7Block Labs recommends as a sequence
- Getting ready for the audit (about 1 to 2 weeks). Let's make sure we're all clear on what we're discussing here. Are we focusing on contracts, infrastructure, or maybe rollups and bridges? Let’s step up our observability game! We need to ensure our Foundry test coverage is solid. If it makes sense, let’s get some blob and DA dashboards going. And don't forget to activate those Forta bots for any key events we need to keep an eye on! (docs.forta.network).
2) Smart Contract Audit (usually takes 2-6 weeks, depends on size)
First, we start by laying out a threat model and setting a baseline with SWC/SCSVS. Next up, we’re bringing fuzzing and invariants into our continuous integration process. Plus, we’re going to get into the nitty-gritty of formal proofs, focusing on those crucial high-impact rules that really matter. Feel free to dive into the specifics right here.
3) Blockchain Security Audit (2-4 weeks)
