Testnet simulations

What is simulated on Whitechain Sepolia, and what is real.

This build runs on Whitechain Sepolia (chain 1874) and Ethereum Sepolia. Some pieces exist only on mainnet, so the testnet uses stand-ins. Everything else runs as it would in production.

Simulated

  • WB Soul. WhiteBIT's identity registry is not deployed on the testnet. A mirror contract with the same interface stands in for it: 0x9822650A99bD33F29E383345F570dAE1e4E00928. Every "Verified by WhiteBIT" label on testnet comes from this mirror. On mainnet, souls live in the soul registry at 0x…2000, and the IsVerified attribute in the attribute registry at 0x…2002.
  • Money. USDT on Whitechain Sepolia (0xcedfB56113143d55b2358b8CFbB0dEB5Ad2f55a7) is a test token with no real value. WBT for gas comes from the testnet faucet.
  • Demo companies. Names such as acme.taz0r.eth and bluejay.taz0r.eth are demo accounts, not real businesses.
The live demo payments were approved with each approver's backup signer. Passkey signing is verified separately, against Whitechain's P-256 precompile.

Real

  • The contracts, the payments and their transactions on Whitechain Sepolia.
  • ENS names and roles on Ethereum Sepolia, and their proofs onto Whitechain.
  • The Ethereum fallback through EnsGate and the OptimismPortal.
