Latch

Latch is a non-custodial on-chain bank for programmable money on Arbitrum

Sepolia. An owner sets spending rules (daily USD budget, max per payment,

approved destinations and actions) and a separate AI agent wallet can only

spend inside them. The contracts enforce every rule with live Chainlink

prices: anything outside reverts on-chain with a named reason and moves

nothing. The owner can pause, revoke, or pull all funds out at any time.

Frontend is a static app with no backend; a companion bot pays through the

account inside its plan.
