Context

Problem & context

Legal teams wanted agents that could negotiate, price, and settle blockchain tasks without exposing sensitive contracts.
Needed privacy-preserving document intake and deterministic on-chain execution for funds held in agent-controlled wallets.

Architecture

Next.js front-end with Framer Motion for interactive agent controls.
Coinbase AgentKit to give each agent a custodial wallet and on-chain action surface.
Nillion SecretVault for encrypted legal document processing before agent execution.
Privy for embedded wallet authentication and seamless onboarding.

Features

Agent-run task proposals that calculate cost and push transactions from delegated wallets.
Secret document ingestion pipeline guarded by Nillion; agents only see redacted hashes.
Multi-party escrow flow with milestone releases triggered by agent assertions.

Challenges

Wallet orchestration for multiple concurrent agent sessions without race conditions.
Balancing privacy (SecretVault) with verifiability for on-chain receipts.
Designing UX that reveals agent intent and costs before signing.

Impact

Won Coinbase pool prize at ETHGlobal Ethereum.
Delivered compliant agent flows for legal documents while keeping signer UX under 2 clicks.
Demonstrated autonomous wallet execution with human-in-the-loop checkpoints.
