1. K2 (Karak) chain balance

   $22 · 1 positionNeeds the team

   The K2 team's bridge on Ethereum now pays balances by Merkle proof (a list that proves your balance). The merkle root is set and claims are not paused. After 2027-09-12 the guardian can sweep what is left.

   1. Ask the K2 team for your Merkle proof. We could not find an official page that gives proofs.
   2. On the OptimismPortal 0xeeCE9CD7Abd1CC84d9dfc7493e7e68079E47eA73 call claimETH(_amount, _proof) for ETH.
   3. For tokens, call claimTokens(_tokens, _amounts, _proof) on the L1StandardBridge 0xBA61F25dd9f2d5f02D01B1C2c1c5F0B14c4B48A3.

2. Funds on shut-down Swellchain

   $8 · 1 position

   Swell closed Swellchain: the final withdrawal deadline was 2026-06-15 and the chain was to run until 2026-06-30. Withdrawals started before 15 June can still be finalized on Ethereum.

   1. If your withdrawal was started before 15 June: after the 7-day proof wait, prove it on the Ethereum OptimismPortal2 0x758E0EE66102816F5C3Ec9ECc1188860fbb87812 (proveWithdrawalTransaction).
   2. Then call finalizeWithdrawalTransaction on the same contract. You pay ETH gas.
   3. If you never started one: Swell said contract withdrawals were possible until 30 June but are technical. Ask Swell support.

3. Prisma Finance leftover funds

   $3 · 2 positions

   Prisma was exploited in 2024 and wound down. You may have collateral left over after a redemption, Stability Pool gains or deposits, or other claimable funds. They are still in the contracts.

   1. Read the wind-down guide linked below to see which pot your row is in.
   2. Leftover collateral: on the Trove Manager contract in your row, Write tab, call claimCollateral(receiver) from your wallet.
   3. Stability Pool 0xed8b26d99834540c5013701bb3715fafd39993ba: call withdrawFromSP(0), then claimCollateralGains(recipient, collateralIndexes). Deposits: withdrawFromSP(amount).

4. Expired Element Finance position

   <$1 · 1 position

   You hold Element v1 principal tokens (PT), yield tokens (YT) or pool shares. All tranches have ended, so they can be redeemed.

   1. Open the tranche contract (tranche_or_pool column) on Etherscan, Write Contract tab.
   2. PT: call withdrawPrincipal(amount, to). YT: call withdrawInterest(amount, to). Both only work after the tranche expiry.
   3. LP shares: exit the Balancer pool with exitPool first, then redeem as above.
