Aave V3 Yield Farming

Supply tokens into Aave V3 lending pools to earn yield, withdraw at any time, and view positions across multiple chains.

Supported Networks: Ethereum, Arbitrum, Base, Optimism, Polygon, Avalanche.

Runtime Mode

This skill is script-only. It does not register aave_* tools.

Call via Python exports:

• aave_positions(chain)
• aave_supply(chain, token, amount)
• aave_withdraw(chain, token, amount=0, max=False)

Imports: from skills.aave.exports import aave_positions, aave_supply, aave_withdraw

Wallet dependency is runtime-only via core.wallet_runtime.

Prerequisites

Before supply/withdraw, wallet policy must allow the transaction path.

Supported Tokens by Chain

Chain	USDC	USDT	DAI	WETH	WBTC
Ethereum	yes	yes	yes	yes	yes
Arbitrum	yes	yes	yes	yes	yes
Polygon	yes	yes	yes	yes	yes
Optimism	yes	yes	yes	yes	yes
Avalanche	yes	yes	yes	yes	yes
Base	yes	—	yes	yes	—

Script Examples

Read positions:

import asyncio
from skills.aave.exports import aave_positions

async def main():
    result = await aave_positions(chain="arbitrum")
    print(result)

asyncio.run(main())

Supply 100 USDC:

import asyncio
from skills.aave.exports import aave_supply

async def main():
    result = await aave_supply(chain="arbitrum", token="USDC", amount=100)
    print(result)

asyncio.run(main())

Withdraw partial / all:

import asyncio
from skills.aave.exports import aave_withdraw

async def main():
    part = await aave_withdraw(chain="arbitrum", token="USDC", amount=50)
    print(part)
    full = await aave_withdraw(chain="arbitrum", token="USDC", max=True)
    print(full)

asyncio.run(main())

Error Handling

Error	Cause	Solution
Unknown chain	Invalid chain name	Use: ethereum, arbitrum, base, optimism, polygon, avalanche
Unknown token	Token not available on that chain	Check supported tokens table
Insufficient balance	Not enough tokens in wallet	Check wallet balance before supply
Amount must be positive	Zero or negative amount	Use a positive number
Policy violation	Wallet policy blocks transaction	Update wallet policy
Not running on a Fly Machine	Local dev environment	Supply/withdraw require deployed env with wallet
