Cancel / revoke

Two ways to back out of a COMMITTED exchange:

• Buyer cancels via cancelVoucher — buyer loses buyerCancelPenalty, gets the rest back. Seller keeps the cancel penalty.
• Seller revokes via revokeVoucher — buyer gets full refund; seller forfeits their sellerDeposit to the buyer.

Either ends the exchange.

await (await sdk.cancelVoucher(exchangeId)).wait()

When to use

• Buyer cancel: you changed your mind before redeeming. Accept the penalty.
• Seller revoke: you can't fulfill (out of stock, wrong info, fraud suspicion). Honor the buyer.
• Neither: don't cancel during an active dispute — the dispute machine takes over.

Common gotchas

• Cancel only works in COMMITTED. After redemption, use the dispute path.
• Revoke is a real cost to the seller. Use sparingly. Track revoke rate as a quality signal in your internal ops.

• Exchange state machine.
• Raise a dispute.
