What is Auto-Compounding?
Auto-compounding is a DeFi mechanism that automatically reinvests earned rewards back into the principal position. Instead of manually claiming and redepositing rewards, smart contracts or protocols handle this process, maximizing the compound interest effect.
Manual vs Auto-Compounding
Manual Compounding
- User must claim rewards periodically
- Pay gas for each claim and deposit
- Often forget or delay, losing returns
- Time-consuming for multiple positions
Auto-Compounding
- Protocol handles harvesting automatically
- Gas costs shared across all users
- Optimal frequency determined by strategy
- Truly passive yield generation
Compound Interest Impact
Example at 50% APR:
- No compounding: 50% return
- Annual compounding: 50% return
- Monthly compounding: 63.2% return (APY)
- Daily compounding: 64.8% return (APY)
How Auto-Compounders Work
- Harvest: Bot or keeper claims rewards
- Swap: Rewards converted to deposit asset
- Deposit: Funds added back to position
- Repeat: Process runs continuously
Platforms with Auto-Compounding
- Beefy Finance: Wide range of auto-compounding vaults
- Yearn Finance: Built into vault strategies
- Convex Finance: Auto-compounds CRV rewards
- Autocompound: Dedicated compounding service
Optimal Harvest Frequency
Balances:
- More frequent = better compounding
- Less frequent = lower gas costs
Optimal frequency depends on:
- Reward rate
- Gas costs
- Total value locked
Fee Considerations
- Compounders charge fees for service
- Usually 0.5-5% performance fee
- Still beneficial if yields are high
- Compare net APY after fees
Benefits
- Maximized compound interest
- Truly passive investment
- Gas cost efficiency
- No manual intervention needed
