Why Moonwell

Non-Custodial, Audited, Secure — Why Moonwell

The protocol handles lending logic; private keys and asset custody stay entirely on the user side.

Non-custodial — you hold the keys

Assets never touch a central server. Every interaction runs wallet-to-contract on-chain. The protocol can't move funds, freeze accounts, or block a withdrawal.

Low gas fees, instant finality

Two-second confirmations. Gas under a penny. On Base and OP Mainnet, even small positions make economic sense — the fees don't eat your returns like they do on mainnet Ethereum.

Smart contract audits & bug bounty

Halborn went through the code line by line. Certora proved it correct mathematically. Code4rena pays independent researchers to find anything those two missed. Three separate teams, three different approaches, before a single dollar enters the contracts.

Cross-chain — Base, Optimism, Moonbeam, Moonriver

One wallet works on every supported chain. Spot a better rate elsewhere? Switch networks in one click — no new sign-up, no separate account.

Automation

Mamo — Automated DeFi Compounding Engine

Mamo monitors open positions, harvests rewards, reinvests them and rebalances when rates shift — all while custody stays with the wallet owner.

🌱

What Mamo does

Set the strategy — which asset, how aggressively. Mamo compounds interest, rebalances across pools and harvests rewards. Assets remain in the connected wallet throughout.

USDC

USDC on every chain

Got stablecoins not doing anything? Put them on any of the four networks. No minimum deposit, no lock-up period — withdraw anytime.

cbXRP

XRP → cbXRP → yield

Have XRP? Bridge it to Base as cbXRP and put it to work earning lending interest. Still liquid, still yours, now productive.

FAQ

Moonwell FAQ — DeFi Lending, Swaps, Vaults & Staking

Straight answers about how the protocol works, what it costs and what to watch out for.

What is Moonwell DeFi protocol?

A set of smart contracts on the blockchain that let anyone swap tokens, lend crypto for interest, borrow against it, earn automated vault yields and stake WELL. No intermediaries, no gatekeepers. The protocol runs across four chains, and over $430 M has already been supplied.

How do I swap crypto on Moonwell?

Pick what you're selling, pick what you're buying, type the amount. The rate shows up instantly — no haggling, no order books. Hit confirm in your wallet, and the tokens land in about two seconds. Gas on Base costs less than a penny.

Which tokens and blockchains does Moonwell support?

The heavy hitters are all here — ETH, USDC, USDT, DAI, WBTC, cbBTC, AERO, WELL, EURC, MORPHO. Across four chains, that adds up to 56 different lending markets. New tokens get added through community governance votes.

How can I earn yield on Moonwell?

Three ways. Supply crypto to a lending market — USDC on Base is paying 7.3 % right now. Or toss funds into a Flagship vault and let a curator auto-compound for you (USDC vault does 6.7 %). Or stake WELL and earn up to 9.5 % APR in WELL rewards. Mix and match as you like.

What's the difference between supplying and borrowing?

Supplying = you deposit crypto and earn interest on it. That deposit also counts as collateral. Borrowing = you take a loan against that collateral and pay interest on the loan. You keep both the collateral and the borrowed funds — withdraw or repay whenever you want, no schedule.

What are Moonwell's fees?

Moonwell itself charges nothing — zero platform fees. The only cost is standard blockchain gas, which on Base and OP Mainnet runs under a cent. Borrowers pay interest on their loan, and every rate is visible in real time before the confirm button. No hidden anything.

Is Moonwell safe and non-custodial?

Moonwell is non-custodial — your crypto sits in smart contracts, not somebody's company wallet. Those contracts have been torn apart by Halborn Security auditors, mathematically verified by Certora, and there's a standing Code4rena bounty paying hackers to find bugs. Is anything in crypto 100 % safe? No. Is this about as hardened as DeFi gets? Yes.

What is WELL token staking?

WELL is Moonwell's own token. Stake it and you earn more WELL — up to 9.5 % APR on Base. You also get voting power over protocol decisions. The catch: there's a 7-day cooldown before you can unstake, and in a worst-case scenario (a protocol shortfall), some staked WELL could get slashed. Right now 932 M+ WELL is staked — about $14.65 M worth.

Do I need an account or KYC to use Moonwell?

No. No account, no email, no ID scan, no KYC. Browse everything without connecting a thing. Ready to act? Plug in a wallet and sign the transaction — that's the entire onboarding.

What are Moonwell Flagship yield vaults?

Think of them as managed funds, but on-chain and fully trustless. A professional curator takes your deposit, spreads it across the best lending pools, auto-compounds the interest and rebalances when rates shift. You sit back. Right now the USDC vault is at 6.7 % APY with $51 M in it, ETH vault at 2.3 % with $33 M, and EURC vault at 3.2 % with $9.5 M.

Moonwell DeFi Protocol — Crypto Lending, Swaps, Yield Vaults & WELL Staking

What is Moonwell?

Moonwell is an open-source DeFi protocol for crypto lending, token swaps, automated yield vaults and WELL governance staking. It operates across Base, OP Mainnet, Moonbeam and Moonriver with a fully non-custodial architecture — smart contracts hold the assets, not a company. More than $430 M has been supplied across 56 active markets, all accessible from a single wallet without registration.

Crypto lending and borrowing on Moonwell

The mechanism is straightforward. A supplier deposits USDC (or another supported asset) into a lending pool. Borrowers draw from that pool and pay interest, which flows back to suppliers — USDC on Base currently yields 7.3 % APY. Every deposit doubles as collateral, so a supplier can later borrow against it without selling. Rates are algorithmic: high utilization pushes rates up to attract more capital, low utilization brings them down. No manual rate-setting, no committees.

Automated yield vaults — USDC, ETH, EURC

Flagship vaults abstract away pool selection and rate-chasing. A depositor puts in a single asset; a professional curator allocates it across the highest-performing lending pools, auto-compounds the interest and rebalances when conditions shift. The USDC vault currently pays 6.7 % APY with $51 M deposited, the ETH vault runs at 2.3 % ($33 M), and the EURC vault targets euro-denominated yield at 3.2 % ($9.5 M). All three operate on Base.

WELL token staking and governance

WELL is Moonwell's governance token. Stakers earn additional WELL (up to 9.5 % APR on Base) and gain voting power over protocol changes — new market listings, rate model adjustments, treasury allocations. Staked WELL (stkWELL) also serves as a backstop: in a Shortfall Event, a portion can be slashed to cover protocol losses. That risk-reward trade-off is the reason the APR exists. Current stake totals 932 M WELL, roughly $14.65 M.

Security audits and self-custody design

Halborn Security performed a manual audit of the codebase. Certora added formal verification — mathematical proofs that the contracts behave correctly under every possible state. A standing Code4rena bug bounty incentivizes independent researchers to find anything the first two layers missed. Three separate review methodologies. The non-custodial design adds a fourth safeguard: even a compromised front-end cannot move funds, because only the connected wallet can authorize transactions.

Supported networks — Base, Optimism, Moonbeam, Moonriver

Base serves as the primary hub — cheapest gas, deepest liquidity, most markets. OP Mainnet taps into the Optimism Superchain ecosystem. Moonbeam operates as a Polkadot parachain for cross-ecosystem reach. Moonriver is the Kusama canary network where new features get battle-tested first. A single wallet address works on all four — no separate accounts needed.
