Fill in a few fields and put a contract on the TCC test chain (chain 91339). No Rust, no CLI — audited template programs, your wallet signs in this page. Every action is checked against the chain before you sign.
Enter the 24-word recovery phrase of your TCC wallet (or the raw seed it was created from). It derives the same address as the TCC wallet, is used only in this tab to sign, and is never sent anywhere.
