SendCheck

SendCheck is a browser-based tool that lets users verify an EVM crypto wallet address before sending funds. It checks the EIP-55 checksum, confirms whether the address is active on the specific network being used, identifies whether it's a wallet or contract, and shows native, USDC and USDT balances. It specifically flags the common mistake of sending USDT to an address that only holds USDC. Checks can be shared via a link that re-verifies live in the recipient's browser. The tool runs entirely client-side, stores no data, and offers a limited number of free checks per day, with a one-time payment option for unlimited use.
