Usage

```python from web3_agent_kit import Chain, ChainManager, Wallet from web3_agent_kit.defi import Uniswap chain_manager = ChainManager(chains=[Chain.BASE]) wallet = Wallet.from_env("PRIVATE_KEY", chain_manager=chain_manager) uniswap = Uniswap(chain_manager=chain_manager, slippage=0.5)

Get quote

quote = uniswap.get_quote("ETH", "USDC", 0.1, chain=Chain.BASE) print(f"0.1 ETH = {quote['amount_out']:.2f} USDC")

Execute swap

result = uniswap.execute( wallet=wallet, token_in="ETH", token_out="0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913", amount=0.1, chain=Chain.BASE, ) print(f"TX: {result.tx_hash}") ```

Aerodrome

  show_root_heading: true
  show_source: true

Aerodrome is a DEX on Base that uses a Uniswap V2-compatible router. python from web3_agent_kit.defi import Aerodrome aerodrome = Aerodrome(chain_manager=chain_manager) result = aerodrome.execute(wallet, "ETH", "USDC", 0.1)

Aave

  show_root_heading: true
  show_source: true

Aave V3 lending/borrowing integration — deposit, withdraw, borrow, repay, and liquidation.

from web3_agent_kit.defi import Aave

aave = Aave(chain_manager=chain_manager)

# Deposit tokens

    action="deposit",
    token="0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48",
    amount=1000,
)

# Get user data
data = aave.get_user_data(wallet.address)
print(f"Health factor: {data.health_factor}")

Curve

  show_root_heading: true
  show_source: true

Curve Finance stableswap integration — swap stablecoins across all pool types, gauge deposits.

from web3_agent_kit.defi import Curve

curve = Curve(chain_manager=chain_manager)
swap_result = curve.execute(
    wallet=wallet,
    pool="0x...",
    token_in="USDC",
    token_out="USDT",
    amount=1000,
)
print(f"Swapped: {swap_result.amount_in} → {swap_result.amount_out}")
