Address checksum invalid

HTTP status: 422 Retryable: No

Description

The address format is recognizable but fails checksum verification (e.g. EIP-55 for EVM addresses). The address may have been transcribed or copy-pasted incorrectly, causing a single character to differ.

Resolution

Re-encode the address with the correct EIP-55 checksum. Web3 libraries provide helpers: ethers.getAddress(), viem.getAddress(), or web3.utils.toChecksumAddress() in ethers.js, viem, and web3.js respectively.
