Intro

I've wanted to have my own dashboard so I can monitor different EVM-based sanctions for certain contracts, and I've finally found some spare time on the weekend to do it!

The app steps through blocks to watch for events from certain contracts (0x40c57923924b5c5c5455c48d93317139addac8fb, 0xdAC17F958D2ee523a2206206994597C13D831ec7) and then indexes the ones that I have noted as "evm-sanction"-worthy.

• As of mainnet block 15294674 there is no overlap of sanctioned addresses in ChainAnalysis Sanctions Oracle and USDT Blacklist.

• Address 0x881d40237659c251811cec9c364ef91dc08d300c was added to the USDT blacklist twice, with 7 months apart - Tx1, Tx2
• Address 0x967bb571f0fc9ee79c892abf9f99233aa1737e31 was added to the USDT blacklist twice, with 3 minutes apart - Tx1, Tx2
• Address 0x707176b584d0ae0c77d3035da8686f8b58cda73b was added to the USDT blacklist twice, with 8 days apart - Tx1, Tx2
• Added 0xfae3ff7e05d921c1d48bbe6676ef5c902e32c801 was added to the blacklist twice, with 8 days apart - Tx1, Tx2
