Can I earn interest on Ethereum in United States legally?

Yes — every venue in our fee table holds the required regulatory authorisations in United States. Always verify the venue's current registration status before signing up.

What's the cheapest way to earn interest on Ethereum in United States?

Among the venues we track, the cheapest path is typically the lowest-fee funding rail on the venue's full-trading-view interface. Simple-Buy interfaces and card-funded transactions cost materially more (1.5-3%+ all-in). See the fee comparison above for current rates.

Is disposing of Ethereum a taxable event in United States?

Yes — most disposal-class actions (sell, swap, send-as-payment) trigger a taxable disposal at fair-market value on the action date. See the tax-primer link above for the United States framework + edge cases.

What documents do I need to earn interest on Ethereum in United States?

Standard KYC at every venue: government photo ID (driver's licence or passport), tax identification, and proof of address (utility bill or bank statement under 90 days). Verification typically completes within 5-30 minutes; manual review for edge cases takes 1-3 business days.

Fee comparison

All-in cost per venue across the most-common payment + settlement paths. Verified 2026-06-02.

Venue	Supply Apy	Min Amount	Withdrawal	Risk Profile
Aave (DeFi lending protocol)	ETH supply: 1.5-3.0% variable; wstETH supply: 1.0-2.5% on top of staking yield	Any (gas-economic threshold ~$200 on mainnet, much lower on L2)	Instant if pool liquidity available; rare delays during high-utilization spikes	Smart-contract risk + utilization/liquidity risk; no protocol insolvency event since launch 2020
Compound (DeFi lending protocol)	ETH supply: 1.0-2.5% variable; cETH receipt token earns over time	Any (gas-economic threshold similar to Aave)	Instant if pool liquidity available	Smart-contract risk; established 2018; v3 launched 2022 with single-collateral-per-market design
Morpho (DeFi optimization layer)	Generally 0.3-0.8% above Aave/Compound base rates for the same asset	Any (sits on top of Aave/Compound)	Same as underlying Aave/Compound pool	Smart-contract risk on Morpho layer + underlying base layer; younger than Aave/Compound
Curve (LP — ETH/stETH or ETH/sETH pools)	Base pool fee: 0.04-0.4% APY; +CRV token rewards 2-8% when active; LP token represents share	Any (gas-economic threshold similar)	Instant; impermanent loss possible if peg breaks (e.g., stETH depeg)	Smart-contract + impermanent-loss + LST-depeg risk; ETH/stETH pool experienced depeg stress in 2022
CeFi (US retail)	Effectively defunct: BlockFi bankrupt 2022, Celsius bankrupt 2022, Genesis bankrupt 2023; Gemini Earn settled SEC 2024 + paused; no live US-retail CeFi yield product at meaningful scale as of 2026-06-02	N/A	N/A	AVOID — the 2022-2023 bankruptcy cohort demonstrated that US CeFi crypto yield was systemically uninsured + Ponzi-adjacent

Regulatory framing — United States

The SEC has aggressively pursued CeFi crypto-yield programs as unregistered securities offerings: BlockFi 2022 ($100M settlement), Gemini Earn 2024 ($400M+ settlement + Genesis bankruptcy fallout), Celsius criminal proceedings. The CeFi US-retail yield market is effectively closed as a result. Protocol staking has softened in regulatory stance (see /how-to/stake-ethereum-us/). DeFi lending on Aave, Compound, Morpho is structurally peer-to-pool — the protocols themselves are not US-licensed entities and US users access them as non-custodial software (no KYC, no broker-dealer registration). The SEC has not pursued enforcement against DeFi lending protocols at the protocol level as of 2026-06-02, though front-end DApp interfaces have faced scrutiny. Yield earned in DeFi is ordinary income at FMV when received; the receipt token (aTokens, cTokens, LP tokens) creates its own cost-basis tracking obligation.

Common gotchas

DeFi receipt tokens accumulate yield in the token's redemption rate, not as separate distributions. aETH (Aave) balance grows as if rebasing; cETH (Compound v2) doesn't change supply but redeems for more ETH over time. Both are economically equivalent but produce DIFFERENT tax-event traces — talk to your crypto-tax software vendor before scaling.
Smart-contract risk is real. Aave is one of the oldest live protocols (since 2020) but has had multiple bugs found + patched + bountied. Newer protocols (Morpho, novel LP designs) carry higher latent-bug risk; budget that into your expected APY.
DEX impermanent loss on ETH/stETH or ETH/cbETH LP positions: the pools were stressed during the 2022 stETH depeg (briefly traded at 0.94 vs ETH). If you're providing LP, you're taking on the risk of the LSTs reverting from their pegs.
Gas costs eat retail yield on mainnet. A $1k supply position on Aave mainnet costs $20-$60 to deposit + $20-$60 to withdraw; at 2% APY that's ~3-4 months of yield consumed by entry/exit. L2 (Arbitrum, Base, Optimism) is the right venue for retail-size positions.
Front-end vs protocol: Aave's UI (app.aave.com) is operated by Aave Companies. The PROTOCOL is the smart contracts on-chain. If the front-end is taken down (regulatory, infrastructure), you can still interact directly with the protocol via Etherscan or alternative front-ends. Plan for this — keep a record of contract addresses.
Reward token economics: protocols sometimes incentivize lending with their native token (Aave, Compound). The native-token reward is income at FMV on receipt + a NEW cost basis. Many users misread these rewards as 'free' but they create complex tax events at distribution.

Step-by-step

Decide between staking yield + DeFi yield (or both). Staking: see /how-to/stake-ethereum-us/. DeFi lending stacks ON TOP of staking by supplying wstETH or rETH instead of plain ETH — net yield 4-5% APY combined. The combination is the most common US-retail ETH-yield strategy in 2026.
Choose an L2 for retail-size positions. Arbitrum, Base, and Optimism all have Aave v3 + Compound v3 deployed with full ETH-market coverage. Gas per transaction is $0.05-$0.50 instead of $20-$60 on mainnet. Bridge your ETH (or LST) to L2 first using the official bridge or a third-party (Across, Hop).
Connect a non-custodial wallet to the protocol's front-end. MetaMask, Rabby, or hardware-wallet-backed setup (Ledger + MetaMask). Verify the URL — phishing sites with near-identical domains are common. Bookmark the official URL after first verification.
Supply your ETH (or LST) to the pool. Approve the token if first time (gas), then supply. You'll receive the receipt token (aETH on Aave v3, cETH on Compound v3) — this represents your position and accumulates yield. Verify the supply APY shown matches the protocol's published rate.
Track yield for tax purposes. DeFi: NOT 1099-DA covered. You self-track via the receipt-token balance changes (Aave rebases) or redemption-rate changes (Compound v3). Most crypto-tax software (Koinly, CoinTracking, CoinLedger) supports Aave/Compound + auto-pulls from wallet address. Set a reminder to export annually.
Plan exit + withdrawal. Withdrawal is instant if the pool has utilization headroom. During high-utilization periods (post-stress, post-event), some withdrawals may queue. Keep your withdrawal amount sized so the pool can cover it OR be prepared to wait. After withdrawal, bridge back to L1 if you're moving to self-custody — bridging is generally not taxable but document the transaction-hash trail.

Tax summary

DeFi yield earned in any form (token-balance rebase, redemption-rate appreciation, separate reward token) is ordinary income at FMV when received. The receipt token (aToken, cToken, LP token) carries its own cost basis = supply amount. Disposal of the receipt token = capital-gain event vs that basis. NOT covered by 1099-DA as of 2026-06-02; self-report on Form 8949 + Schedule 1. CeFi yield is effectively unavailable to US retail post-2022-2023 bankruptcies + SEC settlements.
