Checks 1–7

Autonomous agent that stacks Bitcoin for people who want to buy BTC and forget about it. Users set a plan once (from $0.10 USDT per installment, hourly to 12h); the agent executes every purchase on-chain on Celo: it pays its execution API via x402 micropayments and swaps USDT to WBTC on Uniswap v3, delivering Bitcoin straight to the user's wallet. Non-custodial: funds stay in the user's wallet; fees ($0.005 + 1%) are hard-capped in the verified contract 0xd03ffeBBCaaA8aA21053eEB0EeAde39EFC504189. Agent-usable: any wallet can create a plan on-chain and any x402 client can pay POST /api/execute to trigger a purchase — permissionless.
