   $145 · 2 positions

   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. RNDR never swapped to RENDER

   $16 · 1 position

   You hold old RNDR on Ethereum that was never upgraded. The Render upgrade portal swaps it 1 to 1 for RENDER on Solana. The swap is one-way.

   1. Open the Render upgrade portal. You need an Ethereum wallet with RNDR and a Solana wallet.
   2. Connect both wallets.
   3. Approve RNDR and confirm the upgrade. You pay Ethereum gas.

4. MKR never converted to SKY

   Maker / Sky

   $9 · 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.

5. FTM never moved to Sonic (S)

   Fantom to Sonic

   $2 · 1 position

   You hold FTM on Ethereum that was never moved to S on Sonic. Sonic's guide says the Sonic Gateway bridges it 1 to 1.

   1. Open the Sonic Gateway and connect the wallet that holds FTM on Ethereum.
   2. Select FTM (Ethereum), enter the amount, click Bridge and approve the transactions.
   3. When the Claim button appears, claim your S on Sonic. Sonic's guide is from 2024, so check the Gateway still lists FTM (Ethereum).

6. Lisk L2 balance (closing)

   <$1 · 2 positions

   Lisk's own chain closes on 2026-10-31. Lisk says withdrawing to Ethereum takes about 8 days, and unstaking LSK adds 3 days. Start now.

   1. Open the Lisk bridge (type bridge.lisk.com yourself) and connect your wallet.
   2. Withdraw your assets to Ethereum. If you staked LSK, unlock it first and wait 3 days.
   3. After the wait, prove and finalize the withdrawal on Ethereum. You pay gas on both chains.
