Moonwell’s cleanup operation from one of DeFi’s more costly oracle accidents is still very much in progress. The protocol’s third round of cbETH remediation payments has completed, with 147.12137 ETH sent to wallets affected by a pricing bug that first surfaced in February 2026.
That brings the confirmed cumulative total across all three distribution rounds to approximately 390.62 ETH, a figure that represents months of treasury work, governance coordination, and pro-rata calculations across more than 200 impacted addresses.
What went wrong, and who got hurt
The incident traces back to governance proposal MIP-X43, which introduced a misconfigured Chainlink oracle for cbETH, Coinbase’s liquid staking token. The misconfiguration caused cbETH collateral to be severely mispriced within the Moonwell lending markets.
The estimated net losses fell somewhere between $1.78M and $2.68M across 181 borrowers, spread over a window of just a few days.
A public dashboard tracking 203 impacted wallets has been running throughout the remediation process, giving affected users visibility into where their compensation stands.
How the third round was funded
The primary source was approximately 310,301.6 USDC from the Moonwell treasury, which was converted into ETH for distribution. A secondary source was roughly 19.9 ETH recovered through the incident resolution process itself.
Those two pools were then allocated pro-rata across the impacted wallets, meaning each affected address received a share proportional to their documented losses. Round three’s allocation came to exactly 147.12137 ETH, with 146.5562 ETH confirmed as paid as of August 10, 2026.
