MetaMask Security Incident Triggers Sentora Vault Outflows

Sentora's Morpho vaults saw significant outflows after MetaMask disclosed an ongoing security incident tied to its staking operations on September 30, 2026. The wallet provider stated that user wallets faced no immediate risk.

The Defiant reported that depositors pulled funds from vaults curated by Sentora on Morpho, a lending protocol where third-party managers set the rules for how deposits get lent out. According to The Defiant's report, the outflows are linked to the MetaMask incident by timing, but it does not establish that Sentora's vaults were technically exposed to the problem.

Sentora curated more than $1.1 billion across Morpho Vaults (V2) as of late September 2026, placing it among the largest risk managers on the platform. Its biggest products sit on Ethereum and lean heavily on stablecoins such as PYUSD Main ($425 million), RLUSD Main ($414 million), x Spark RLUSD ($250 million), and PRIME Main ($212 million).

The outflows from Sentora's vaults show that depositors may react to the broader security climate, not just their own direct exposure. This could have a ripple effect on utilization rates, which are currently high due to the large withdrawals.
