DeFi Operations

When to Use

Swapping tokens on DEXs (Uniswap, Curve, 1inch)
Lending/borrowing (Aave, Compound, Morpho)
Staking (Lido stETH, EigenLayer restaking)
Providing/removing liquidity (Uniswap V3, Curve)
Flash loans (Aave, Balancer, dYdX)
Perpetual trading (GMX, dYdX v4)
Yield vaults (Yearn, ERC-4626 vaults)

Prerequisites

MCP: blockchain-rpc-server, defi-protocol-server, price-feed-server
Skills: skill-02 (contract calls), skill-12 (gas), skill-15 (MEV for swaps)
Guardrails: simulate all txs; screen counterparties

Workflow

1. Swap

Get quote from defi-protocol-server or 1inch API
Check price impact (< 1% for large trades; use TWAP if higher — skill-15)
Verify router address against known-good list
Set slippage tolerance (default 0.5%, max 3% without confirmation)
Approve exact amount (never unlimited without explicit user consent)
Execute swap; verify received amount ≥ minOut

2. Lend / Borrow

Protocol	Supply	Borrow	Liquidation Threshold
Aave V3	`supply()`	`borrow()`	Health factor > 1.5 recommended
Compound V3	`supply()`	N/A (Comet)	Collateral factor varies
Morpho	Optimizer bundles	Peer-matched rates	Check LLTV

Always maintain health factor buffer. Monitor oracle price feeds (skill-11).

3. Stake / Restake

Lido: submit() ETH → stETH; check rebasing vs wstETH for integrations
EigenLayer: deposit into strategy contracts; track withdrawal queues
Liquid staking: verify validator set and slashing risk

4. Liquidity Provision

Uniswap V3: select tick range; narrow ranges = higher IL risk
Calculate impermanent loss before deposit
Use defi-protocol-server for current pool APR/TVL

5. Flash Loans

Identify provider (Aave: 0.09% fee, Balancer: 0% on some pools)
Build callback contract with atomic repay logic
Simulate full transaction — revert if unprofitable
Never use flash loans for unbounded external calls

Protocol References

See knowledge-base/protocols/ for addresses, ABIs, and subgraph endpoints per chain.

Risk Checklist

Contract verified and on protocol allowlist
Slippage and deadline set
Health factor / collateral ratio safe
Token approvals scoped to exact amount
MEV protection enabled for swaps > $1,000 (skill-15)
