Conventions

• All amounts are strings in wei to avoid float precision loss.
• Signatures are EIP-191 personal messages over canonical JSON with sorted keys.
• Rate limit: 60 requests per minute per operator. Back off exponentially on 429.
• Every response includes epoch so clients can detect rollover.
