5 liquid lockers listed for Poland
In ChainChoice’s published ranking order, from this category’s 5 providers: those whose terms exclude Poland are removed; naming Poland or a region that covers it counts the same, and those whose terms do not state it come last. Each chip names the basis: a dated check, a region listing, or the provider's own claim.
#1 for PolandConvex Finance (cvxCRV)#1 globallyProvider states broad availability The category's dominant wrapper — 421.5m veCRV, 54.13% of all voting escrow — issuing a receipt that has no redemption at any price and cleared 56.29% below the underlying on a $100k exit at Ethereum block 26,074,948 (28 September 2026).
Contract control and dated incident record of the wrapper itself — 8/10Who controls the votes and the bribes, and what reaches the depositor — 6/10#2 for PolandPirex (pxCVX, Redacted)#2 globallyProvider states broad availability The wrapper whose sponsor dissolved but whose contract did not: pxCVX still burns back to CVX at NAV, permissionless and exercised five times in the week checked, at a fee that on 28 September 2026 ran from 4.91% for the lock unlocking 1 October 2026 to 1.15% for the one unlocking 21 January 2027 — while its only quotable Curve venue priced a $100,000 exit 41.87% below NAV the same day.
The exit that does not exist: measured discount and any contractual redemption — 6/10Contract control and dated incident record of the wrapper itself — 6/10#3 for PolandYearn yCRV#3 globallyProvider states broad availability Yearn's veCRV liquid locker: CRV is minted 1:1 into yCRV and locked forever, the revenue split is enforced by a deployed on-chain splitter, and the only exit is a single Curve pool that priced a $100,000 exit 55.35% below the underlying on 28 September 2026.
Contract control and dated incident record of the wrapper itself — 8/10Who controls the votes and the bribes, and what reaches the depositor — 6/10#4 for PolandStake DAO (sdCRV Liquid Locker)#4 globallyProvider states broad availability The second-largest veCRV wrapper (118,470,811 veCRV, 15.21% of supply, re-read at block 26,074,948 on 28 September 2026): the only major CRV wrapper whose receipt holders actually direct the underlying vote, and 85% of harvested Curve revenue reaches them per a deployed contract getter — but the deposit is permanent, the only exit is its own Curve pool at a 54.95% haircut on $100,000, and the getter that sets that 85% answers to a 3-of-5 multisig with no timelock.
Who controls the votes and the bribes, and what reaches the depositor — 7/10What happens if the base protocol changes or dies, and whether the wrapper can unwind at all — 7/10#5 for PolandCLever (clevCVX, AladdinDAO)#5 globallyProvider states broad availability CLever locks depositors' CVX into vlCVX and lends them up to 50% of it as clevCVX — a synthetic claim on future harvest, not a receipt for the principal; the deposit is genuinely unwindable (vlCVX expires) but clevCVX itself exits only through a Curve pool holding about $50,000 of CVX on 28 September 2026 whose gauge the protocol has struck through, or a 903,245-token Furnace queue that at 528 CVX a day would take about 1,710 days to clear.
