If you are looking for specific chain support that is not listed, we can accommodate most EVM requests.
Address format
For EVM networks, token contract addresses must be provided as a hex 0x address.
- Lowercase addresses are accepted.
- Checksummed addresses are recommended for human review.
Providing an EOA (wallet) address instead of a contract address will typically return an error or an empty analysis.
