Mamo — DeFi Yield Aggregator (Moonwell on Base)

Mamo is a DeFi yield aggregator built by Moonwell on Base chain. It deploys per-user smart contracts that split deposits between Moonwell core markets and Morpho vaults for optimized yield, with auto-compounding of rewards.

Chain: Base (8453) Strategies: USDC stablecoin, cbBTC lending, ETH lending, MAMO staking

Setup

cd ~/clawd/skills/mamo/scripts  # or wherever this skill lives
npm install
export MAMO_WALLET_KEY=0x...     # wallet private key
export MAMO_RPC_URL=https://...  # optional, defaults to Base public RPC

Commands

# Create a yield strategy (deploys your personal strategy contract via on-chain factory)
node mamo.mjs create usdc_stablecoin
node mamo.mjs create cbbtc_lending
node mamo.mjs create eth_lending

# Deposit tokens (approve + deposit to your strategy contract)
node mamo.mjs deposit 100 usdc
node mamo.mjs deposit 0.5 cbbtc

# Withdraw tokens
node mamo.mjs withdraw 50 usdc
node mamo.mjs withdraw all cbbtc

# Account overview — wallet balances + strategy positions
node mamo.mjs status

# Current APY rates
node mamo.mjs apy
node mamo.mjs apy usdc_stablecoin

How It Works

1. Create strategy → Calls the on-chain StrategyFactory to deploy a personal proxy contract owned by your wallet
2. Deposit → CLI approves token spend, then calls deposit(amount) on your strategy contract
3. Yield accrues → Strategy splits funds between Moonwell + Morpho, auto-compounds rewards via CowSwap
4. Withdraw → Only the owner (your wallet) can withdraw. Funds go directly to your wallet

Strategy addresses are stored locally in ~/.config/mamo/strategies.json (the on-chain registry may not be updated for user-created strategies).

Key Addresses

Security

• Use a dedicated hot wallet — not your main holdings
• Only deposit what you're comfortable having in a hot wallet
• Store MAMO_WALLET_KEY in env vars, never in committed files
• All transactions are simulated before sending
