Introduction
What Aquifer is, why it exists, and what makes it different from other yield products.
Aquifer is an AI-powered USDC yield vault on Sui. You deposit once. A Gemini AI agent reads live rates across 10 Sui DeFi protocols every few minutes and automatically moves your funds to wherever the yield is highest. You earn passively without tracking anything.
Aquifer is currently live on Sui testnet. No real money is involved. Claim free testnet USDC and try it in under two minutes.
Why Aquifer exists
DeFi yields shift constantly. The best rate on Suilend today may be beaten by NAVI tomorrow. Monitoring 10 protocols manually and moving funds between them is impractical. Aquifer solves this with an AI agent that never sleeps, never misses a rate change, and acts on every opportunity automatically.
Key properties
No lockups. Withdraw any time. Funds are available in a single transaction, even if they are currently deployed across multiple protocols.
Real yield. Actual USDC interest is injected into the vault on-chain. No points systems, no IOUs, no vesting schedules.
Fully transparent. Every rebalancing decision the AI makes is recorded on-chain and stored permanently on Walrus decentralised storage. Anyone can read the AI's reasoning, verify the allocation it chose, and check the live rates it was given.
Open source. All Move contracts and the agent code are public on GitHub.
