Claiming

At or after the unlock time, the beneficiary withdraws the tokens in one transaction. Before that time the contract rejects the attempt.

Who can claim

Only the beneficiary named when the lock was created. Not the depositor, even though they supplied the tokens, and not Arcanium. A lock can be claimed once; a second attempt reverts.

When

At the unlock second exactly, and any time after. There is no deadline and nothing expires — tokens left unclaimed stay in the contract until the beneficiary comes for them.

If the interface is unavailable

The locker is an ordinary contract and does not depend on this website. Calling claim(lockId) on 0x0aB1fbD6c01f4908f509746393DE25849aE2a9E7 from any tool that can reach Arc does the same thing. Lock pages here read the contract directly, so they also work when our indexer is behind.

Nobody can claim early and nobody can extend a lock. If a date was set wrongly, the only options are to wait for it or to abandon the tokens.
