Open developer sandbox · test SIGIL faucet

Build. Break. Build again.

Testnet is the open developer sandbox. It uses test-only SIGIL with no economic claim. Hit the faucet, deploy contracts, run T1 jobs, register validators, and exercise the same client and RPC surfaces before touching canary or mainnet.

Use the testnet endpoint and faucet for wallets, integration tests, validators, and contract rehearsals.
