Harvest
What your accepted work earned. Each closed epoch is posted to the harvest book as a Merkle root; after a one-day veto window you claim it, and the contract pays the address in the tree. Nothing expires.
No payout address yet. or paste one in wallet.
A claim is an ordinary transaction from your wallet, paid in ETH gas. Anyone can send it for any address; the contract still pays only the address in the tree, so a claim sent for a pasted address lands in that address.
