Cambio Offline Experience
Writeable Access Phrases for Analog T3 Notes
Generate a phrase-protected Cambio note with a 5-character checksum, hand it off like cash, and redeem it using the same safety net that governs T3 on-chain. No wallet or funds required—this is a guided simulation of the workflow.
Why Phrases?
Some Cambios print a QR, others stamp a phrase you can jot down. Each note’s phrase is hashed on-chain and paired with a 5-character checksum so only the holder can redeem it—even without connectivity.
Guardrails in Every Step
The demo mirrors production rules: issuance locks funds in escrow, redemption checks for phrase misuse, and every action emits audit trails for regulators.
1. Issue a Phrase-Protected Cambio Note
Create a note with a custom amount and phrase, or let T3 generate one from an approved word list. The demo mirrors the contract: keccak256 note IDs plus a 5-character checksum and shareable QR link so you can reopen this setup anywhere.

Write the phrase and 5-character checksum on paper or print the QR. Anyone holding it can redeem inside the HalfLife window once they prove knowledge of the phrase.
Validate the Phrase and Release Funds
Enter the phrase and 5-character checksum you received along with the amount you want to cash out. The demo enforces the same constraints as the smart contracts: phrase must match, amounts can only be redeemed once, and any mismatches raise descriptive errors.
