Optimism is an Ethereum optimistic rollup Layer 2 known for its governance token and strong DeFi ecosystem. Use the free checker to screen a Optimism (OP) address for an OFAC SDN match, available entity label matches and ransomware address matches where the network is covered.
How to check an Optimism wallet for AML
- Paste your OP wallet address in the input above.
- Run the Optimism check and review the risk score, sanctions hits and activity shown in the result.
- Choose the paid $1 report on the website or in @cryptoamlscan_bot, where payment is $1 in USDT or 75 Telegram Stars. A PDF is available when generation succeeds.
What is AML screening for Optimism?
AML screening for Optimism wallets compares a submitted address with sanctions address data, ransomware address lists where the network is covered, and available labels. Entity name matching uses labels rather than a complete list of sanctioned wallets.
Optimism's Superchain initiative connects it to Base and other OP Stack chains, and it shares Ethereum's exact 0x address format: this checker asks which network before pulling any data instead of guessing.
Key risk signals for Optimism wallets
Like all EVM Layer 2s, Optimism shares address formats with Ethereum. Bridge activity can transfer AML risk from Ethereum mainnet to Optimism and vice versa.
- OFAC SDN match: Direct comparison with digital currency addresses in the official SDN data copy.
- Entity name label match: Available labels are compared with UN, UK OFSI, Australia DFAT and Switzerland SECO entity names, not wallet address lists.
- Ransomware address match: BTC addresses are compared with the Ransomwhere export.
- Optional Merkle Science labels: The paid report attempts enrichment where supported; these labels are not a guaranteed sanctions source.
Optimism AML compliance: what you need to know
Optimism's Superchain architecture, where OP Mainnet, Base (operated by Coinbase), Mode, and other chains share the same underlying technical stack, means that a risk event on one chain has direct implications for all others. On June 9, 2022, Optimism handed 20 million OP tokens to market maker Wintermute for liquidity provisioning, but Wintermute supplied a multisig address that had not yet been deployed on Optimism's network. An attacker deployed that exact address first, took control of the funds, and drained the full 20 million tokens before Wintermute could recover them, later returning 17 million and keeping roughly 3 million. Velodrome, the dominant DEX on Optimism, experienced coordinated wash trading in its early liquidity mining phase where participants traded between controlled wallets to earn OP token incentives without genuine price discovery. The OP token airdrop in May 2022 was widely gamed through Sybil attacks where coordinated wallet clusters performed scripted on-chain activity across preceding months to qualify for maximum allocation. These clusters are labeled in Nansen datasets, making wallets involved in that Sybil activity persistently flagged even if subsequent transaction history appears clean.
Check an Optimism address in Telegram
To check an Optimism (OP) address, send it to @cryptoamlscan_bot. Your first check is free with no registration, and the free grant follows your Telegram user ID across all CryptoAML bots. The free result shows the OFAC result, balance, transaction count and first seen activity, with paid report fields locked. A paid check costs $1 in USDT or 75 Telegram Stars.
Optimism AML risk types: reference table
| Risk type | What it means | What to do |
|---|---|---|
| Airdrop Sybil farming | Address is part of a documented wallet cluster gaming the May 2022 OP airdrop | Elevated due diligence: labeled cluster in major analytics datasets. |
| Wintermute incident exposure | Funds traceable to the June 2022 20M OP token theft (attacker retained ~3M) | Request source-of-funds documentation. |
| Superchain bridge exposure | Funds bridged from Base, Mode, or another OP Stack chain with unclear origin | Trace back to the originating chain before clearing. |
| OFAC SDN listing | Optimism address directly on OFAC sanctions list | Do not transact. Report to compliance immediately. |
| Wash-trading liquidity pattern | Repeated trades between a small set of controlled wallets on Velodrome or similar DEXs | Treat volume/liquidity metrics as unreliable: manual review. |
