walletAddress

Your wallet address on the specified blockchain where payments are sent. For EVM chains (Base, Base Sepolia), provide a valid Ethereum address (42 characters including 0x prefix). For Solana chains, provide a valid Base58-encoded public key (32-44 characters).

For EVM addresses, WAF performs EIP-55 checksum validation for typo detection when the address uses a mix of lower and upper case letters. You can bypass this validation by providing the address in all lowercase or all uppercase.
