1. Unclaimed Polygon PoS withdrawal

   Polygon PoS bridge

   $998 · 1 position

   You burned tokens on Polygon to withdraw to Ethereum, and the checkpoint is done, but the exit was never run on Ethereum. The tokens wait in the bridge.

   1. Open Polygon Portal and connect the wallet that withdrew.
   2. Find the withdrawal in your transactions and press Initiate Claim.
   3. Approve in your wallet, then press Claim Tokens. Pay the Ethereum gas fee. The tokens go to the burner address.

   1. Open the Blur Pool contract on Etherscan and go to Write as Proxy or Write Contract.
   2. Connect the wallet that holds the balance.
   3. Call withdraw with the amount in wei (18 decimals), then confirm.

3. K2 (Karak) chain balance

   $26 · 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.

4. Archived L2 bridge funds

   Archived L2s

   $4 · 1 positionMay not work

   This chain shut down and its state is gone, so no one can prove a withdrawal now. The Ethereum bridge still holds the money; only the chain team can release it.

   1. Use the official bridge of the chain you withdrew from (linked next to each of your positions).
   2. Check that chain's official site for a refund or recovery notice.
   3. Without the chain's final state nobody can prove a withdrawal. Only the chain team can release the bridge funds.

5. Splits or Zora rewards not withdrawn

   0xSplits, Zora

   $1 · 1 position

   Money was sent to you through 0xSplits, or you earned Zora creator or referral rewards, and it is still inside the contract waiting for you to withdraw.

   1. Splits: open SplitMain 0x2ed6c4B5dA6378c7897AC67Ba9e43102Feb694EE on Etherscan and call withdraw(account, withdrawETH, tokens[]) with your address. Anyone can call it.
   2. Zora: call withdraw(to, amount) on ProtocolRewards 0x7777777F279eba3d3Ad8F4E708545291A6fDBA8B (same address on Base and other Zora chains), from the account that earned the rewards.
   3. The Splits app (app.splits.org) can also help.

6. Funds in old Ethereum contracts (2015-2021)

   <$1 · 1 position

   You have a balance in an old Ethereum contract (The DAO, EtherDelta, IDEX, the 2017 ENS registrar, DigixDAO and others). Each contract has its own withdraw call. Use the wallet that owns the position.

   1. The DAO: on the DAO token 0xbb9bc244d798123fde783fcc1c72d3bb8c189413 call approve(0xbf4ed7b27f1d666546e30d74d50d173d20bca754, yourBalance). Then call withdraw() on the WithdrawDAO contract 0xbf4ed7b27f1d666546e30d74d50d173d20bca754. It pays 1 ETH per 100 DAO.
   2. EtherDelta 0x8d12a197cb00d4747a1fe03395095ce2a5cc6819: from the wallet that deposited, call withdraw(amount) for ETH or withdrawToken(token, amount) for a token. Amounts are in the token's smallest unit.
   3. IDEX v1 0x2a0c0dbecc7e4d658f48e01e3fa353f44050c208: call withdraw(token, amount). Use token 0x0000000000000000000000000000000000000000 for ETH. It reverts if your last IDEX activity was fewer than 240 blocks ago.
   4. 2017 ENS registrar 0x6090a6e47849629b7245dfa1ca21d94cd15878ef: call releaseDeed(labelhash) for the name. The labelhash is keccak256 of the name without .eth. The deposit goes back to the deed owner.
   5. Other contracts (DigixDAO, Neufund and more): use the contract's own withdraw or refund function on Etherscan from the owner wallet. Check the contract's code first.

7. MKR never converted to SKY

   Maker / Sky

   <$1 · 1 position

   You hold MKR, or MKR in the old DSChief voting contract, that was never converted to SKY. The converter still works. Its fee is 5% now (read on-chain 2026-10-01) and rises 1 point every 3 months.

   1. Open the Sky app and connect your wallet.
   2. If your MKR is in the old DSChief voting contract, first call free(amount) on that contract.
   3. Approve MKR, then convert it to SKY. You get 24,000 SKY per MKR minus the fee.
   4. Without the app: call mkrToSky(usr, mkrAmt) on the converter 0xA1Ea1bA18E88C381C724a75F23a130420C403f9a.
