More tagged CrimeEnjoyor contracts, retail wallet breakdowns, and an all-time high in delegations on our EIP-7702 dashboard
We’ve made several updates to our @Dune dashboard to improve accuracy, expand contract tracking, and surface clearer adoption patterns ↓
🧩 Clarification on reporting around our EIP-7702 findings
After we released the last update, some headlines misrepresented the core message. Here’s what’s actually happening:
EIP-7702 is not flawed, and it is safe to use in retail wallets. The mechanism itself works as intended.
The spike in delegations comes from multiple malicious contracts that share identical bytecode. These are not part of legitimate wallet infrastructure. In fact, it is not possible for users of trusted wallets to authorize these contracts, as wallets only delegate to their own audited contracts. These malicious contracts act as sweepers. They are deployed after a private key has already been leaked, and are used to automatically redirect any funds sent to the compromised EOA.
Attackers are quick to adopt any new mechanism that allows them to do bad things. That doesn’t mean EIP-7702 is unsafe in general.
We did not build detection tools. What we did was verify and label the most reused malicious contract so its intent is transparent, traceable, and easy to flag in tooling and dashboards.
🔐 New contract tracking
CrimeEnjoyor2 and AdvancedCrimerEnjoyor are new highly reused sweeper contracts that have been now fully verified.
Together with HardcodedCrimeEnjoyor, these contracts account for a large portion of new malicious delegation behavior.
📈 All-time high in daily delegations + multichain expansion
Last Friday marked a new ATH in EIP-7702 delegation activity, once again driven primarily by sweeper contracts. Since then, sweeper usage has expanded Ethereum to @unichain and @gnosischain.
🧹 New “Sweeps activity on Ethereum” section
We’ve added a dedicated view to track malicious delegation behavior tied to the ‘Crime’ category of delegate contracts. This section analyzes sweeps activity from authorized addresses that delegated to malicious contracts, and includes:
‣ Recent sweep transactions
‣ Total ETH swept, with breakdown by contract type
‣ Gas usage distribution by contract category
‣ Total ETH used for authorizations
‣ Leaderboard of authorizations from compromised EOAs
‣ Count of unique addresses authorized by crime-tagged contracts
🛠️ Improved data accuracy
Some authorization logic isn’t fully captured by Dune’s native functionality yet, especially around authorization validity and authority recovery.
To support more precise analysis, we pre-processed this data ourselves and published a public dataset.
→→→ Search in our dashboard: `dune.wintermute_research.dataset_pectra_authorizations`
We’ll be updating it regularly, and welcome others to use it in their own dashboards and queries.
This dataset now powers several new views in our dashboard:
‣ Daily breakdown of valid vs. invalid authorizations
‣ Distribution of valid/invalid authorizations and unique authorized addresses
‣ Cumulative and categorical charts based on valid-only authorizations
‣ Recent authorizations list with authority and validity flags (updates with delay)
👛 Retail Wallets section enhancements
‣ Daily and cumulative delegation charts now include breakdowns by retail wallet
‣ New pie chart shows delegation volume split across supported wallets
→ Currently includes @MetaMask, @wallet, @AmbireWallet, @Uniswap, and others
→ Improves visibility into actual user adoption across wallet flows
With more verified contracts, cleaner delegation data, and ongoing support from you, we’re making EIP-7702 adoption more visible, auditable, and understandable.

31.5.2025
While EIP-7702 brings new convenience, it also introduces new risks
Our Research team found that over 97% of all EIP-7702 delegations were authorized to multiple contracts using the same exact code. These are sweepers, used to automatically drain incoming ETH from compromised addresses.
More insights from our @Dune dashboard ↓
What’s the “Crime” tag in our dashboard?
These are mostly delegate contracts designed to auto-sweep funds from EOAs with leaked private keys.
We highlighted this pattern in our original post, based on behavior seen across authorizations from compromised addresses.
At that time, the bytecode was not verified. Now, we’ve reversed the EVM bytecode into Solidity and published a verified version called CrimeEnjoyor.
Why verify it?
Because verified code makes intent visible. We no longer need to infer malicious behavior from transaction patterns or metadata.
This lets us:
‣ Shows exactly what the malicious contract does
‣ Add a public warning
‣ Clearly label it for other users
The CrimeEnjoyor contract is short, simple, and widely reused. This one copy-pasted bytecode now accounts for the majority of all EIP-7702 delegations.
It’s funny, bleak, and fascinating at the same time.
It also reinforces a key point: New primitives like EIP-7702 expand what is possible, but without verification, labeling, and transparency tools, it becomes harder to tell infrastructure from exploitation, especially for new users.
New updates to our dashboard
We’ve added labels for delegate contracts used by:
‣ @TrustWallet
‣ Porto by @ithacaxyz
‣ @thirdweb
‣ v1 of @Uniswap Calibur
‣ @FireblocksHQ
and more crime-tagged contracts
With more compromised contracts tagged, more activity can be surfaced and more users can be protected.
You can now also explore detailed activity analysis of EIP-7702 users on Ethereum, including which contracts they interact with. Currently, this covers only MetaMask workflow, and we’ve excluded any approve interactions to provide additional insights for the data.
@Uniswap @JumperExchange @eulerfinance currently account for 95% of all EIP-7702 flows on Ethereum as they’re early integrators.
