setIsSentinel, the function used to adjust addresses granted the Sentinel role, is owner-gated and the Owner is Uniswap governance's mainnet Timelock.Uniswap Labs launched Uniswap Earn in July 2026. Consistent with past Uniswap Labs-originated protocol launches, the ownership roles on the smart contracts that power Uniswap Earn were assigned to Uniswap Governance. In Earn, a user deposits USDC, USDT or ETH in the Uniswap app, the deposit flows into a Morpho Vaults V2 instance, and Gauntlet curates the allocation. In the run up to launch, Gauntlet deployed the three vaults and transferred ownership to DUNI's Timelock address.
Morpho Vaults V2 splits control across four roles.
| Role | Capabilities | Appointed by | Held on the Earn vaults by |
|---|---|---|---|
| Owner | Appoint the Curator, add and remove Sentinels, transfer ownership, set vault name and symbol. One address only. | Prior Owner, via setOwner | DUNI, via the mainnet Timelock |
| Curator | Set caps and risk parameters, enable yield sources, set fees, appoint allocators. Most actions timelocked. One address only. | Owner | Gauntlet |
| Allocator | Move capital between enabled yield sources, within the bounds the Curator has set. Multiple addresses allowed. | Curator | Gauntlet |
| Sentinel | Lower caps, revoke pending Curator actions, pull assets out of lending markets back into the vault. Takes effect instantly. Multiple addresses allowed. | Owner | Gauntlet |
The Owner has no claim on deposits and does not set risk parameters, allocations, or fees directly. Fee management sits with the Curator. Governance's leverage runs through its power to appoint and replace the Curator, which is why ownership was structured this way.
Performance fee is currently zero on all three vaults.
Gauntlet has upgraded the signing infrastructure it uses across the vaults it curates. Specific to Uniswap Earn vaults, this has resulted in new addresses for the Sentinel role.
The three vaults, all on Ethereum mainnet:
| Vault | Address |
|---|---|
| Uniswap USDC (uniUSDC) | 0x5B453493D2328E7F747eb2e66446eFe707728be7 |
| Uniswap USDT (uniUSDT) | 0xb8274eFADB953FE9ae052D481a3FC5B6A3ceD703 |
| Uniswap ETH (uniETH) | 0x98D2b241DA14c5dd848812708Eb8A1F3c5512f9d |
The Owner of all three is the Timelock at 0x1a9C8182C09F50C8318d769245beA52c32BE35BC.
We propose calling setIsSentinel(address,bool) six times: once to grant the role to each new Gauntlet address, and once to revoke it from each legacy address.
| Vault | New Sentinel (grant) | Legacy Sentinel (revoke) |
|---|---|---|
| uniUSDC | 0xF66b884D1906F37c1692CEa63564316FF975Cd75 | 0xc3FE37DB03B5720D1684bE2e0200E0Af07853Ad9 |
| uniUSDT | 0xD9b023059dfD00C2DC68C4d8d0c70BCaA30577Db | 0x2745513325d4Ce5724e5B6Fb663356C427AfdeCc |
| uniETH | 0x4Ff315B873d6e5Ad8ff7fF3e17D340862762cc2f | 0xc63A00De30AeB5666a8aC3478a4D119D38058c7E |
A vault can hold more than one Sentinel, so the grants and the revocations are independent actions.
For every vault, the Curator stays Gauntlet, the Owner stays the Timelock, and all parameters such as caps, adapters and fees are unchanged.
Six transactions, all sent from the Timelock, all with value = 0. Function selector 0x920ed706.
