   Alpaca Finance

   <$1 · 2 positions

   You hold Alpaca v1 ibTokens (deposit receipts) on BNB Chain. The vault still pays out the underlying token.

   1. Open the ibToken contract (contract column) on BscScan and go to Write Contract.

5. zkSync Lite balance not claimed

   <$1 · 2 positions

   zkSync Lite was shut down on 2026-05-04. Remaining balances are claimable on Ethereum through a claim contract and a withdrawal portal. Your account is on that list and has not claimed.

   1. Open the zkSync Lite withdrawal portal and connect the wallet that owned the account.
   2. The portal finds your address in the final state, builds the proof and sends the claim. Follow its prompts.
   3. Confirm the Ethereum transaction. Tokens go to your L1 address. Matter Labs sponsors gas for the first 100,000 withdrawals.

6. Polygon zkEVM balance

   <$1 · 1 position

   Polygon zkEVM's sequencer stopped on 1 July 2026. Wallet-held funds not bridged before then can be claimed on Ethereum in a claim UI. Polygon treats unclaimed assets as abandoned after 2027-12-31.

   1. Open the Polygon zkEVM claims site and connect the wallet that held the funds.
   2. Pick your balances and send the claim transaction on Ethereum.
   3. Funds locked inside DeFi contracts are not auto-migrated. Ask Polygon through the forum post.

9. Hyphen bridge funds stuck

   Biconomy Hyphen

   <$1 · 3 positions

   Hyphen (Biconomy) is no longer supported. Liquidity provider positions may still be withdrawn from the contracts. Transfers that never arrived need the Biconomy team. We could not confirm this from official docs.

   1. If you provided liquidity, call removeLiquidity with your NFT id on the chain's LiquidityProviders contract on Etherscan (Write tab).
   2. For a farming NFT, first call withdraw(nftId, to) on the LiquidityFarming contract.
   3. If you sent a transfer that never arrived, contact Biconomy; only their executors can release it.

10. 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.

11. Ended Sablier stream (no price)

    $0 · 1 position

    An ended or canceled Sablier stream whose token has no known price. Most are airdrop vesting or spam tokens, so the value is unknown and may be zero.

    1. Open the Sablier app and connect the wallet that owns the stream.
    2. Press Withdraw on the ended stream if you want the tokens.
    3. Be careful with unknown tokens: many are spam.
