The tester never pays network fees. The connected wallet signs to prove control; Orru’s demo payer covers Sepolia gas and Orru’s relayer covers Creditcoin gas.

​
Start here: prepared judge wallet

This is the default judging path because its three Semuni pay cycles have already been accepted on Creditcoin. The wallets and their keys are provided with the DoraHacks submission. They are testnet accounts holding nothing of value. Exact amounts and salts are never published anywhere.
1

Import and connect

Import one of the judge accounts into MetaMask or Rabby, open orru.xyz/connect, connect it and sign the wallet ownership message. The wallet needs no ETH or CTC.
2

Review and issue

Review the three accepted Semuni pay cycles, generate the proof in the browser and issue the band-only statement.
3

Borrow and verify

Borrow from the disclosed demo pool, then copy the credential id or public link and open it in a private window. Public verification needs no wallet or Orru account.

​
Optional: full demo faucet

The faucet is open to anyone with a wallet they control. It creates three demo off-chain payment records, anchors their commitments in one Sepolia transaction, waits for Attestcoin coverage and then waits for Orru’s scheduled relayer to record the accepted commitments on Creditcoin.
  1. Open orru.xyz/try, connect a fresh wallet and sign.
  2. Select Create demo history. The wallet pays nothing.
  3. Leave the page open. It checks every 15 seconds and shows four real stages: sent to Ethereum, Ethereum confirmed, Attestcoin covered and Creditcoin accepted.
  4. When the history is ready, continue through review, proof, statement issuance, borrowing and public verification.
The normal wait is 10 to 15 minutes. Attestcoin intentionally trails the latest Ethereum block, and Orru’s relayer runs every five minutes. Polling more often cannot make either stage advance sooner. If the history is still not ready after 25 minutes, check the latest attest workflow in GitHub Actions.
The faucet spends real Sepolia gas from a testnet hot key. It is a demo service, not a source of spendable funds. Operators should keep the key minimally funded and use persistent, shared abuse controls when exposing the route from a serverless deployment.

​
What the faucet actually creates

Semuni represents the off-chain payer model. No ERC-20 salary transfer occurs on Sepolia. The three private demo records are simulated; their commitments are genuinely anchored on Ethereum, authenticated by Attestcoin and accepted on Creditcoin. The later zero-knowledge proof and issued statement are real testnet proofs and contract state.
