Token Incentive Yields
Additional yields from network/protocol tokens:
Strongest Token Incentives:- Mode (aggressive points → MODE)
- Optimism (OP grants to protocols)
- Blast (points + native yield)
- Mantle (treasury-funded rewards)
- Arbitrum (ARB to some protocols)
- Base (none currently, Coinbase backing)
- zkSync/Scroll/Linea (potential future airdrops)
Native Yield (Unique to Blast)
Blast offers automatic yield:
- ETH: ~3-4% from Lido staking
- USDB: ~5% from MakerDAO DSR
- No action required—balances auto-increase
This is additional to any DeFi yields earned.

Migration Considerations
Moving Between L2s
When to Migrate:- Yield differential >5% APY
- New incentive programs launching
- Security concerns on current chain
- Airdrop positioning
- Bridge fees: 0-0.1%
- Gas on both chains
- Potential slippage on large moves
- Time cost of repositioning
Staying Put
Reasons to Stay:- Established positions with locked tokens
- Small yield differences (<3%)
- High migration costs relative to position
- Airdrop eligibility requirements
FAQ
Which L2 has the best yields right now?It varies by strategy. For stablecoins, Mode and Blast often offer highest total returns (including points/native yield). For ETH-based strategies, Arbitrum and Optimism have mature ecosystems with competitive yields.
Should I use one L2 or many?Diversification across 2-4 L2s reduces risk and captures more opportunities. But spreading too thin increases complexity and gas costs. Find your balance based on portfolio size.
How important are pending airdrops?Significant potential value, but speculative. Don't overweight airdrop farming at the expense of real yields. Consider airdrops as bonus potential, not primary strategy.
Will L2 yields compress over time?Likely yes. As ecosystems mature and more capital enters, competition reduces yields. Incentive-driven yields typically decrease fastest. Focus on sustainable yield sources.
Which L2 is best for beginners?Base offers the easiest onboarding via Coinbase. Polygon has the lowest fees for experimentation. Arbitrum has the most protocols to explore. All three are beginner-friendly.
How do I track yields across multiple L2s?Use aggregators like Fensory, DeBank, or Zapper. They display positions across all chains in unified dashboards. Essential for multi-chain strategies.
