You have a wallet and some stablecoins, and you keep hearing that DeFi yield farming only makes sense on a Layer 2 because the fees on Ethereum itself eat small positions alive. That part is true, and it is why fees stopped being the main question. This page takes you from a wallet on Ethereum to a first deposit earning interest on a Layer 2, and tells you what the second move should be.

Know where the yield comes from

A Layer 2 (L2) is a separate network that runs on top of Ethereum and does the same work far more cheaply. Base, Arbitrum, Optimism and zkSync are the ones you will hear about most. Yield farming means putting tokens into a DeFi protocol so it can use them, for example lending them to borrowers, and being paid for it.

The L2 sorts out the cost. By September 2026 median transaction fees had converged to $0.02 on Base, $0.03 on Optimism, $0.04 on Arbitrum and $0.05 on zkSync, according to a market report published that month. At those prices gas is no longer what decides whether a farm is worth it.

What decides it is the source of the yield, and there are only two kinds. One is organic yield: interest paid by borrowers, or fees paid by traders. The other is incentive yield: tokens or points the protocol or chain hands out to attract deposits, often ahead of a TGE (token generation event, the day a project's token is created and starts trading). Incentive yield can be large, but it stops when the incentives stop.

Blast is the example worth keeping in your head. Its total value locked (TVL, the dollar value of everything deposited) peaked at $2.2 billion in June 2024 and fell to about $55 million by December 2025, a 97% decline that EarnPark and SpotedCrypto both tie to its airdrop incentives running out. The Block found the same pattern across the sector:

many emerging L2s have followed similar trajectories with heavy, incentive-driven activity ahead of a token generation event, resulting in a points-fueled surge in usage, followed by a rapid post-TGE decline

So the rule for a first farm is this: start where the yield is organic and the chain is big, and treat incentive yield as a separate, later decision you make on purpose.

What you need before you start

  • A self-custody wallet that supports Ethereum L2 networks

    The same address works on Ethereum and on EVM-compatible L2s like Base and Arbitrum. Free.

  • Stablecoins you can afford to lock up, such as USDC

    Any amount works on an L2. The worked example below uses $500.

  • A small amount of the token the chain charges fees in

    Check the chain's own documentation for which token that is. At $0.02 to $0.05 a transaction, a few dollars' worth covers many interactions.

  • A way onto the L2

    Either an exchange account that lets you withdraw directly on the L2 network, or the chain's official bridge.

  • About an hour for the first time

    Most of it is reading what each signature request asks for before you approve it.

That is the whole list. You do not need a points tracker, an eligibility checker or a second wallet yet.

The wallet is the one item worth spending money on. Funds sitting in an exchange account are the exchange's to freeze or pause, and the Base upgrade on September 30, 2026 showed it plainly: Binance paused Base deposits and withdrawals an hour before the fork. A wallet whose keys sit on a device you own means the keys signing your farm's transactions never touch a browser extension's storage or an exchange's servers.

Your first deposit on Base or Arbitrum

Pick Base or Arbitrum, and I'd pick Base for a first run. Both are where the money is. Base ranked first on DefiLlama's DeFi TVL at $4.41 billion as of May 30, 2026, while Arbitrum One held the most total value secured of any L2 at $20.50 billion, per CoinLaw's roundup of L2BEAT data. The two measure different things, which is why they disagree on the ranking. Both are classed by L2BEAT as Stage 1, meaning users can exit without the operator's permission, where zkSync Era and Linea were still Stage 0, operator-controlled, in SpotedCrypto's comparison. Base gets the nod for its lower median fee and because its lending market is the one with a track record: Morpho deposits on Base grew from $354 million to over $2 billion through 2025.

The first farm is a stablecoin deposit into a lending protocol. Borrowers pay interest on what they take out, and depositors get it. EarnPark's table put Morpho on Base at 4% to 10.8% APY on USDC and Aave V3 on Base at 4% to 7% on USDC and USDT (APY is annual percentage yield, the yearly return including compounding). Those were the rates when that piece was written. Rates move with borrowing demand, so read the live figure on the protocol itself.

From Ethereum wallet to earning interest

  1. Add the L2 network to your wallet

    Select or add Base (or Arbitrum) in your wallet's network list. You should see: the network name in the selector and a balance of zero at your usual address.

    2 minutes
  2. Get the fee token onto the L2

    Withdraw a few dollars of the chain's fee token from an exchange, choosing the L2 as the withdrawal network, or send it through the chain's official bridge. You should see: a small balance on the L2 in your wallet.

    Minutes from an exchange; bridge times vary by chain
  3. Move your stablecoins the same way

    Send the USDC by the same route. Double-check the network on the exchange's withdrawal screen before confirming. You should see: your USDC balance on the L2.

    Exchange withdrawal fees vary
  4. Open the protocol from its own address

    Type the address in yourself or use a bookmark you saved from the protocol's official channels. Never follow a link from an ad, a reply or a direct message. Connect your wallet. You should see: your USDC balance shown on the deposit screen, on the right network.

    5 minutes
  5. Approve, then deposit

    The first signature lets the protocol move your USDC; the second makes the deposit. Read the amount in the approval before signing. You should see: a supplied balance and the current APY on your position.

    Two transactions, typically cents each
  6. Write it down

    Note the date, amount, APY at deposit and fees paid. You should see, a week later: a supplied balance slightly above what you put in.

Does the gas still matter at $500?

Say you deposit $500 of USDC on Base at 4% APY, the bottom of the range EarnPark gave for Aave V3 there. A plain transfer on Base had a median fee of $0.02 in September 2026, and SpotedCrypto found complex DeFi interactions cost 3 to 10 times a simple transfer. You need three of them: approve, deposit, and eventually withdraw.

Deposit$500
Interest over one year at 4%about $20
Cost per DeFi interaction (3 to 10 × $0.02)$0.06 to $0.20
Three interactions$0.18 to $0.60
Fees as a share of first-year interestabout 1% to 3%

On Base, gas takes a few percent of a small stablecoin position's yearly interest at most. Getting the money onto the chain (exchange withdrawal fees) is not counted here and can cost more than the farm itself, so move funds once rather than in dribs.

What goes wrong the first time

Chasing the biggest number. EarnPark listed Velodrome LP positions on Optimism at 5% to 25% and GMX's GLP on Arbitrum at 5% to 15%, against 4% to 7% for plain lending on Aave. The higher figures come from different positions with different risks: an LP (liquidity provider) position holds two tokens whose prices move against each other, and GLP is the other side of traders' bets. You can tell this has happened when you cannot say in one sentence who is paying you. If that's you, go back to lending until you can.

Farming on a chain or protocol that is about to empty out. Smaller L2s fell 61% on average since June 2025, EarnPark found, and Kinto and zkLend shut down entirely. In September 2026 Silicon Network's wind-down trapped roughly $9.75 million in deposits and Nostra lost $3.5 million to a manipulated price feed, as Shattered.io reported. The warning sign is TVL falling after a token launch or incentive season ends. The fix is to withdraw early, not after the exit queue fills.

Moving money during a network upgrade. Base's Cobalt hard fork activated at 18:00 UTC on September 30, 2026, and Binance stopped Base deposits and withdrawals from 17:00 UTC, CryptoTicker reported. Balances were unaffected, but a transfer sent into that window sits waiting. If an exchange shows a network as suspended, wait it out; check the chain's announcements before any large move.

Trusting the wrong link. The lending deposit, and later any airdrop claim, happens on a page you reach through a link, and that link is where wallets get drained. Real claim instructions name their own address and network. Aligned Layer's own blog, for example, sends eligible wallets to community.alignedlayer.com and says small allocations claim on Base. If a page asks you to sign an approval for a token you were not depositing, close it.

Points programs come second

The fair case against everything above is that nobody moved to L2s for 4% on stablecoins. The big payouts have come from airdrops and points, and they have. Lighter's LIT token launched on December 30, 2025 with 25% of supply airdropped fully unlocked, according to Decentralised.news. Aligned Layer's Genesis Drop set aside 8.74% of the 10 billion ALIGN supply for the community and based eligibility on having held at least $50 of tokens such as Starknet, ZKsync, Scroll or Taiko.

That is a real argument, and it is why points are the second thing rather than nothing. What it does not support is starting there. Points are an off-chain score a protocol keeps for you, which it may convert to tokens later, and the conversion is the protocol's call. Lighter's terms let it adjust, remove or reverse points even after they appear credited, KuCoin reported. Its formula is deliberately non-linear: doubling volume does not double points. And as of August 10, 2026, no Season 2 conversion rate to LIT had been published. Programs also run on fixed rhythms: AFX's Season 1 lasted eight weeks with settlement every Monday at 00:00 UTC, and its points carry across seasons to a single TGE.

Once your first deposit has sat for a week and you have withdrawn and redeposited once to see the whole cycle, you know the mechanics every points program is built on. Then pick one program, read its own announcement for the tasks, the cadence and what disqualifies a wallet, and decide if the hours are worth it. Our breakdown of bridging, protocol interactions and activity thresholds covers how that positioning works across several campaigns, and the list of L2 networks without a token yet is where to look for which ones.

Airdrop farming strategies

Questions people ask at this stage

Among the major ones, Base had the lowest median fee at $0.02 in September 2026, followed by Optimism at $0.03, Arbitrum at $0.04 and zkSync at $0.05. All were under $0.10. Complex DeFi interactions cost 3 to 10 times a simple transfer on every chain, so the gap between them is cents.

They are the two biggest, and together they held over 75% of L2 value in The Block's figures. Base led on DeFi TVL and fees; Arbitrum held more total value secured and hosts GMX, Aave and Pendle. For a first stablecoin deposit either works, and both are Stage 1 on L2BEAT's scale.

No. If your exchange lets you withdraw directly on the L2 network, that is usually simpler. The official bridges are heavily used: as of September 2026 the Base bridge held $6.26 billion and the Arbitrum Bridge $5.55 billion. Use the chain's own bridge, reached from its official site, not a link someone sent you.

Only if a protocol decides to reward it, and that is not known in advance. Aligned Layer rewarded holders of several L2 tokens, but Circle, for instance, had confirmed no Arc airdrop and no eligibility list as of mid-September 2026. Count lending interest as the return and any airdrop as a possible extra.

Usually not for a first farm. Smaller L2s fell 61% on average since June 2025 and several protocols shut down with deposits inside. A high rate on a small chain is most often incentive yield, and it ends when the incentives do.
