Open a channel. Pay it. Break it.

Everything below uses real EIP-712 signatures (secp256k1, the key type of an Ethereum wallet) made in your browser and checked by the same code the contract's tests run. No wallet, no funds, nothing sent. Time is simulated so you can wait out a dispute window in one click.

This browser cannot make random keys (crypto.getRandomValues). Use a current Chrome, Edge, Firefox or Safari.

3. Try to cheat it

Each button builds a bad ticket, for real, and the payee side refuses it with the contract's error name.
