🚀 Blast L2: The First Ethereum Layer 2 That Pays You to Hold ETH and Stablecoins
Blast is a new Ethereum Layer 2 (L2) that looks like a typical optimistic rollup—but it has a major twist:
It’s the first L2 where your ETH and stablecoins earn native yield automatically.
No staking. No farming. No extra steps. Just bridge and hold.
Imagine deposit $ETH in Mitosis L1 from Blast L2, then deposit in Mitosis Matrix Vault or EOL
Follow Mitosis on X for more updates.
But how exactly does it work? And why do some people not see the yield right away?
Let’s break it all down — for both regular users and developers.
🧠 What Does “Native Yield” on Blast Mean?
When you bridge ETH or stablecoins to Blast:
| 🔹 Asset | 🔹 What Happens | 🔹 Yield Source |
|---|---|---|
| ETH | Auto-staked in Lido | Ethereum staking rewards |
| USDC, USDT, DAI | Converted to USDB, backed by sDAI | MakerDAO's DSR (Savings Rate) |
✅ Your ETH or USDB balance increases over time, automatically.
There’s no need to interact with any DeFi protocol or staking platform.
This is what Blast calls native yield — the yield is built directly into the L2 chain itself.
💸 Yield Is Credited to Wallet Balances
If you're using a normal wallet (EOA) like MetaMask:
- Your ETH balance rebases (grows) as Lido yield flows in.
- Your USDB balance rebases based on interest from sDAI.
- The growth happens passively, on-chain, and automatically.
📈 You don’t need to claim anything. Just hold your assets on Blast.
⚠️ Why Some Users or dApps Don’t See Yield
This is where it gets important:
Blast has three Yield Modes, and they only apply to smart contracts — not regular wallets.
🧱 Yield Modes for Smart Contract Accounts:
| Mode | Balance Rebase | Yield Earned? | Notes |
|---|---|---|---|
| Void (Default) | ❌ No | ❌ No | Safe default; avoids unexpected behavior |
| Automatic | ✅ Yes | ✅ Yes | Like EOAs; balance increases over time |
| Claimable | ❌ No | ✅ Yes (manual claim) | Yield is stored separately and must be claimed |
So if a smart contract dApp is using the default Void mode, it won’t earn or display yield — even though the Blast network supports it.
➡️ Developers must set the yield mode intentionally when deploying contracts on Blast.
🧪 Example: Wallet vs Smart Contract
| User Type | Sees Yield? | Balance Grows? | Extra Steps Needed? |
|---|---|---|---|
| MetaMask user (EOA) | ✅ Yes | ✅ Yes | ❌ No |
| Smart contract (Void mode) | ❌ No | ❌ No | ✅ Must opt in |
| Smart contract (Automatic mode) | ✅ Yes | ✅ Yes | ✅ Must opt in |
| Smart contract (Claimable mode) | ✅ Yes | ❌ No (manual claim) | ✅ Must opt in |
🪂 Yield + Points = Double Rewards
Blast also runs an ongoing Points System:
- 🌉 You earn points when you bridge ETH or USDB.
- 📲 You earn more points when you use Blast dApps.
- 🪙 Points convert to $BLAST tokens in airdrops.
So on Blast, you’re getting:
- ✅ Real, on-chain yield on your ETH and stablecoins
- 🎁 Points that lead to future token rewards
🧱 Tech Stack and Ecosystem
- Built as a custom Optimistic Rollup (not based on OP Stack or Arbitrum Orbit)
- EVM-compatible
- 7-day withdrawal period (typical for optimistic rollups)
- Yield is managed at the protocol level, not through dApps
Blast has an expanding app ecosystem:
- Thruster (DEX)
- Pac Finance (lending)
- Orbit (on-chain gaming)
- Munchables (notable exploit + recovery case)
🔐 Security and the Munchables Hack
Blast was battle-tested early with a $100M exploit on the Munchables game. The result?
- 💰 All funds were recovered
- 🤝 Community + whitehat support was strong
- 🔒 Audits and security practices were improved immediately
It proved the team could handle pressure and recover fast.
🔚 Final Summary: Why Blast Stands Out
| Feature | Blast | Other L2s |
|---|---|---|
| ETH earns passive yield? | ✅ Yes | ❌ No |
| Stablecoins earn passive yield? | ✅ Yes (USDB) | ❌ No |
| Yield credited automatically? | ✅ Yes (EOAs + Auto mode) | ❌ No |
| Smart contract control over yield? | ✅ Yes (3 modes) | ❌ No |
| Airdrop + Points system? | ✅ Yes | ✅ Some |
| Withdrawals | 7 days (Optimistic) | ~7 days |
🧠 TL;DR
- Blast is the only L2 where your wallet balance increases passively.
- ETH is auto-staked via Lido, and stablecoins are converted to USDB (earning via sDAI).
- Regular wallets (EOAs) always earn.
- Smart contracts must choose a yield mode: Void (no yield), Automatic (rebase), or Claimable (manual claim).
- On top of yield, Blast gives Points for airdrops.
- It’s the most capital-efficient L2 live today.
