Signing
Create a challenge to sign message
Generates a challenge for signing a message from a specified user-controlled wallet. This endpoint supports Ethereum-based blockchains (using EIP-191), Solana and Aptos (using Ed25519 signatures). Note that Smart Contract Accounts (SCA) are specific to Ethereum and EVM-compatible chains. The difference between Ethereum’s EOA and SCA can be found in the account types guide. You can also check the list of Ethereum Dapps that support SCA: https://eip1271.io/.
