DeFi UX is Broken: Moonwell Aims to Fix That

Watch on YouTube

Seed phrases, bridges, gas, price feeds, and agents that can get socially engineered. Most of it still isn’t built for the masses.

Key takeaways

  • Luke Youngblood moved from AWS principal engineer to Coinbase, where he helped launch staking networks including the Ethereum Beacon Chain, before founding Moonwell.
  • Moonwell is an open lending and borrowing app that has been live on Base since day one in August 2023, with about 250,000 users.
  • Passkey wallets, thirdweb on-ramps from 40 fiat currencies and cheap intent bridges remove the hardest parts of onboarding.
  • Momo, Moonwell's DeFi agent, runs through an audited contract that lets it optimize yield but never withdraw user funds.
  • Luke says the late-2025 oracle incidents left bad debt of about 1% of Moonwell's TVL, and the team is adding fallbacks to on-chain DEX prices.
  • Next steps include Ethereum mainnet expansion and lending against tokenized real-world assets like stocks, metals and Treasuries.

Making lending easy enough for anyone

In this remote Hodl Up episode, Luke Youngblood, founder of Moonwell, explains how he went from building cloud infrastructure to running one of Base's leading lending apps. His focus is simple: make DeFi usable for people who have never touched it, and make it safe.

"Crypto has been way too hard to use; the user experience has been way too challenging," Luke said. The conversation covers his path from AWS and Coinbase, Moonwell's onboarding design, governance and compliance, decentralization, the Momo AI agent, the oracle incidents and Moonwell's long-term goals.

From AWS to Coinbase to Moonwell

A decade before this recording, Luke was a principal engineer at Amazon Web Services helping companies adopt the cloud. With his brother, he began building proof-of-stake infrastructure around 2016 and 2017, and in 2018 helped the Tezos Foundation launch its network. Coinbase then hired him to build out staking rewards.

His biggest Coinbase project was launching the Ethereum Beacon Chain in 2020. Experimenting with Uniswap, Compound and Aave during COVID lockdowns gave him his DeFi "aha moment," and he left in early 2022 to launch Moonwell. When the Base team shared its plans in 2023, he decided Moonwell had to be there on day one.

How Moonwell onboards normies

Luke designed Moonwell around the three questions every newcomer asks: which wallet, how to back it up and how to fund it. Passkey wallets use Face ID or Touch ID, so there is no app to download or seed phrase to store. Thirdweb supports on-ramps from 40 fiat currencies, and US users can on-ramp up to $500 by Visa debit card without KYC, through a Coinbase and Visa partnership. Intent bridges move funds in from other chains for a few cents.

Governance and decentralization

The Moonwell Foundation, a Cayman foundation, runs light KYC and sanctions screening on grant recipients, while WELL token holders vote on grants and all protocol upgrades. Luke argued for "maximal decentralization at the protocol layer," ideally immutable contracts. The interface layer can be more centralized, and companies building useful front ends or agents may fairly charge fees there.

Momo, an agent that cannot lose your funds

Luke warned that many trading agents have been socially engineered into giving away private keys. Momo avoids that by design. "The agent can't control your wallet directly." It deploys a contract owned by the user's wallet, can move funds between vaults and compound rewards within a set slippage tolerance, but cannot withdraw. "Most agents need guardrails like that: 'can't lose funds' rather than 'I hope it doesn't lose funds.'"

Momo was about to become an installable web app, with borrowing, a Visa debit card and tokenized stock baskets planned. Luke sees agents becoming financial tutors and robo-advisors.

Lessons from the oracle incidents

Luke called the October and November 2025 oracle events "pretty shocking," saying more than 30 lending protocols took on small amounts of bad debt. In his account, volume-weighted prices broke on October 10 when Binance's auto-deleveraging drove prices on that venue far below DEX prices. A Balancer exploit then affected a price source in November.

Moonwell's bad debt was about 1% of TVL, and just under half had been repaid from reserves at the time of recording. The team switched some liquid staking tokens to exchange-rate feeds and is researching DEX price anchors. "We have to trust but verify a little."

Base users, regulation and the road ahead

On Moonbeam and Polkadot, Moonwell had a smaller, more European audience. On Base, about 90% of users are American and many are small depositors. Luke expects the GENIUS Act to drive US banks into stablecoins, while he is less certain about euro stablecoins. He also argued against gatekeeping: "Don't treat people like children."

Moonwell plans to expand to Ethereum mainnet and lend against tokenized stocks, precious metals, Treasuries and corporate credit. Success means "billions of dollars in collateral, billions of dollars in loans and hundreds of millions of users."

FAQ

Frequently asked questions

What is Moonwell?

Moonwell is an open lending and borrowing protocol, live on Base since August 2023. Users can lend crypto to earn yield or borrow against their assets. It is governed by WELL token holders and is planning to expand to Ethereum mainnet.

What is Momo by Moonwell?

Momo is Moonwell's DeFi agent. It moves user funds between markets to earn the best available yield and compounds rewards. It runs through an audited contract owned by the user's wallet, so it can optimize positions but cannot withdraw funds.

How do you start using Moonwell without a crypto wallet?

Moonwell supports passkey wallets created with Face ID or Touch ID, so there is no app download or seed phrase. Users can then buy crypto with fiat through a thirdweb on-ramp that supports 40 currencies.

What happened with Moonwell and the 2025 oracle issues?

Founder Luke Youngblood says faulty price feeds in October and November 2025 created bad debt of about 1% of Moonwell's TVL. The protocol is repaying it from reserves and adding safeguards such as fallbacks to on-chain DEX prices.
