chainpeek (Tanod) read-only preflight of a USDC or USDT transfer
chainpeek (Tanod) read-only preflight of a USDC or USDT transfer: pass, warn or fail from balance, gas, pending nonce, issuer blacklist, pause, recipient checks and a simulated transfer. Use when an agent is about to send USDC or USDT and needs one pass, warn or fail with reasons first.
