Description
TakumiPay is an all-in-one DeFi platform that lets you pay, swap, and earn across multiple chains — with an AI agent built in to do the work for you.
Instead of clicking through wallets and approving every transaction manually, you set one spending budget and let your agent act on your behalf. It can pay for services
automatically, move idle funds into yield, and handle multi-step tasks from a single voice command — always staying inside the limits you define.
The trust model is the core of the product. You approve a budget once, and that approval is enforced on-chain, not by trust in us. Under the hood, your regular
wallet is upgraded into a MetaMask Smart Account (EIP-7702), and you sign a single spending delegation (ERC-7710) with a cap and an expiry. From then on, the agent
can act autonomously — but it can never spend more than you authorized, and you can revoke it at any time.
Progress During Hackathon
Shipped the full agent-payments stack end-to-end on Base Sepolia. Users upgrade their wallet to a MetaMask Smart Account (EIP-7702) and sign a single on-chain spending budget with an expiry. From there, the in-app AI agent acts autonomously within those limits: it pays for premium services via x402 detecting the 402 challenge, settling through the 1Shot relayer with gas paid in USDC, and retrying with proof, all with no approval popup and deposits idle funds into DeFi protocols on the user's behalf. Also wired multi-agent coordination(Wallet Agent x Defi Agent) .Everything is voice-driven via built-in speech-to-text, cross-chain (EVM, Solana, Sui)
