- Observed description
- Paste a wallet address and the chain you are about to send on. SendCheck checks the EIP-55 checksum, whether the address is actually active on that network, EOA or contract, native + USDC + USDT balances — and flags the USDT-instead-of-USDC trap. Every check is shareable: the link re-verifies live in the viewer's browser. Free, client-side, no account.
