Yearn prepares to launch $yPRISMA liquid locker staking system.
The current yPRISMA staking contract will be deprecated this Thursday May 16th at 00:00 UTC.

Yearn Finance is rolling out a new yPRISMA liquid locker staking system based on its YearnBoostedStaker (YBS) architecture, and will deprecate the current yPRISMA staking contract as part of a broader overhaul of how its liquid locker tokens earn yield. Users who stake yPRISMA will need to migrate to the new contract before or after the deprecation time, with the new system designed to pay out stablecoin yield and improved, time‑boosted rewards without fixed lockups. This change follows Yearn governance proposal YIP-77, which introduced a new unified staking experience for yLockers—Yearn’s “liquid locker” tokens that tokenize locked governance positions from external DeFi protocols such as Curve and Prisma Finance. yPRISMA represents Prisma’s ve-style locked governance exposure in liquid form, allowing holders to remain liquid while still sharing in governance-derived benefits like protocol fees and vote incentives. Under the revamped system, yLocker holders (including yPRISMA) stake into the YearnBoostedStaker contract and earn weekly rewards denominated in a vault‑wrapped stablecoin (mkUSD for yPRISMA) plus additional yLocker incentives, with rewards boosted the longer they stay staked and no explicit lock or early-exit penalty at the contract level. The deprecation of the existing yPRISMA staking contract and launch of the new YBS-based yPRISMA pool is part of a coordinated rollout of a new yLockers ecosystem that began in spring 2024. The updated system standardizes how revenue from protocol fees and vote-maximized bribes is collected, converted to ecosystem stablecoins, and distributed through a single staking interface for all yLocker tokens. For Prisma ecosystem participants, the migration matters because it changes the operational path to capture bribe and fee income via yPRISMA, consolidates staking under Yearn’s new architecture, and introduces a more capital-efficient, time‑boosted rewards design that is meant to be extensible to future liquid locker integrations.
