Murmur — Autonomous DeFi Agent
Murmur's Team
Problem Statement
Autonomous trading agents today operate as black boxes — users hand over funds with no visibility into decision-making, no onchain enforcement of risk limits, and no verifiable record of what happened or why. Trust is assumed, not proven. If the agent makes a bad trade, there's no receipt, no audit trail, and no way to verify the reasoning. Users have no control over position sizing, daily exposure, or risk profiles once they delegate. Murmur solves this by making every layer transparent and verifiable: decisions are attested on Filecoin with cryptographic receipts, trade execution is gated by onchain-enforced limits in per-user non-custodial vaults, and the agent's reasoning (via private Venice AI inference) produces structured decisions that pass through a deterministic 14-check risk gate before any swap executes. Users set the bounds. The agent operates within them. Every action has a hash. Every hash is onchain.
Murmur is an autonomous DeFi trading agent that converts real-time social sentiment and onchain signals into permission-gated trade execution on Base. It ingests 9 Santiment metrics across social and onchain dimensions, normalizes them into z-scores, scores candidates across 3 strategy playbooks, deliberates via Venice AI (llama-3.3-70b) for private inference, enforces a 14-check deterministic risk gate, and executes swaps through per-user non-custodial TradeVaults via Uniswap V3 on Base Sepolia. Every decision is cryptographically attested — receipts are stored on Filecoin via Lighthouse, linked to the agent's ERC-8004 onchain identity, and exposed as pay-per-request endpoints via the x402 protocol (Merit). The agent's capabilities are also registered as an OpenServ multi-agent service. Users connect their wallet, deposit USDC into a non-custodial TradeVault (deployed per-user via VaultFactory), and set trading limits that are enforced onchain. The agent trades autonomously within those bounds. No custody. No trust assumptions. Full audit trail.

Interested in continuing development if there's traction — particularly expanding the signal stack beyond Santiment and adding more DEX venues beyond Uniswap V3.
