Moonwell reports 135% rise in USDC borrowing on Ethereum after interest rate overhaul

Moonwell, the decentralized lending protocol, saw USDC borrowing on its Ethereum mainnet markets jump 135% week-over-week, with USDT borrowing climbing 87% over the same stretch. The catalyst: a governance-approved overhaul of the protocol’s interest rate model curves for both stablecoins.

The numbers are striking on their own, but they’re actually a step down from even larger spikes in earlier weeks, when USDC borrowing surged 148% and USDT borrowing rocketed 236%.

What changed under the hood

On July 29, 2026, Moonwell’s community passed a governance proposal that adjusted the interest rate model (IRM) curves for its USDC and USDT markets. The proposal also introduced borrowing rewards, meaning users now earn WELL tokens for taking out loans.

Moonwell currently supports supply, borrowing, and incentive distribution across several assets on Ethereum, including USDC, USDT, ETH, and cbBTC. WELL token incentives are active across both sides of those markets, rewarding lenders and borrowers alike.

Moonwell’s multi-chain footprint

The protocol isn’t operating exclusively on Ethereum. Moonwell runs across Ethereum, Base, and Optimism, giving it a presence on three of the more active networks in DeFi today.

One of its more notable tools is USDC Anywhere, which enables cross-network lending. The idea is to let users access USDC liquidity regardless of which chain they’re sitting on, reducing the friction that comes with having capital siloed across multiple Layer 1s and Layer 2s.

The Ethereum expansion itself is relatively recent. Moonwell launched its Ethereum mainnet lending markets in 2026, adding to its existing Base and Optimism deployments.

What this signals for DeFi lending

The fact that borrowing increases have been sustained across multiple weeks, even if the percentage gains are moderating from 236% down to 87% for USDT, suggests something beyond pure mercenary capital chasing yield.

The governance mechanism Moonwell used to implement these changes is worth noting. Rather than a core team unilaterally adjusting rate parameters, the IRM curve modifications went through a community proposal and vote.
