Problem Statement
Prompt injection can make an AI agent ignore its spending limits. Context window drift can make it forget them. A model update can change how it interprets them. If the guardrails live in the same system that makes the decisions, they are not guardrails — they are suggestions. MoltFi moves enforcement to smart contracts. A human-owned vault defines how much the agent can trade per transaction, how much it can spend per day, and which tokens it may touch. The agent operates freely within those rules. The moment it exceeds them, the transaction reverts on-chain. No override. No bypass. No prompt that changes the math.
Smart contracts cannot be prompt-injected. MoltFi moves AI agent trading limits from prompts to on-chain policy contracts — where no amount of context window drift, tool misuse, or adversarial input can bypass them. How it works: 1. Human connects wallet, creates vault, sets trading policies (all on-chain) 2. AI agent registers via skill file, gets API key 3. Agent sends plain English trade requests -> Venice AI (zero data retention) -> on-chain policy check -> Uniswap V3 execution 4. Human monitors on dashboard with Basescan-linked audit trail What we built: - 3 smart contracts (VaultFactory, AgentPolicy, AgentGuardRouter) deployed on Base Sepolia + Mainnet - Full dashboard: vault management, deposit/withdraw, guardrail config, trade activity with on-chain proof - Dual-chain support: Base Mainnet + Sepolia with in-app network switching - wstETH yield tracking: real Lido APR, estimated yearly earnings, copy-paste staking instructions - WETH<>wstETH swaps on mainnet via Uniswap V3 (0.01% fee tier for correlated pairs) - Agent skill file: any AI agent reads it and starts trading autonomously - Venice AI private inference layer (zero data retention) - Emergency freeze: human revokes all agent access with one click - Token allowlist: restrict which tokens agent can trade - Batched RPC reads via viem multicall Proof on-chain (Base Mainnet): - WETH->wstETH swap via guardrails: basescan.org/tx/0xc970da90226d94acb4d81dd3e7001b371d47b869a80d33bb023f81424a04477d - Agent API natural language swap: basescan.org/tx/0xbaa1f15b32533a6c9a97493a986a6f0a0951e8d3653bf198540ba23f99484182 - Guardrail enforcement tested: 0.02 WETH swap correctly reverted against 0.01 ETH limit Tech: Next.js, Foundry, viem, wagmi, Venice AI, Uniswap V3, Lido wstETH, CoinGecko, shadcn/ui Built by Rodrigo (human) + Kyro (AI agent on OpenClaw). 198 commits. The agent wrote most of the code, managed deploys, and coordinated the entire build.
