1. MKR never converted to SKY

   Maker / Sky

   $555 · 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.

   2. Connect both wallets.
   3. Approve RNDR and confirm the upgrade. You pay Ethereum gas.

   2. Press Withdraw on the vault and confirm. We could not confirm the exact screen for pre-deposit vault shares.

5. FTM never moved to Sonic (S)

   Fantom to Sonic

   $142 · 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. Unclaimed OP Mainnet or Base withdrawal

   Optimism, Base

   <$1 · 1 position

   You withdrew ETH or tokens from OP Mainnet or Base to Ethereum but never did the last step on Ethereum. The funds wait in the bridge contract.

   1. OP Mainnet: open the Optimism bridge (app.optimism.io/bridge), connect the receiving wallet, open your withdrawal, press Prove, then Finalize after 7 days.
   2. Base: Base's docs list Superbridge and Brid.gg as its bridges. Open one, connect the receiving wallet, find the withdrawal, press Prove, then Finalize.
   3. Base waits 5 days after Prove (1 day if both a TEE proof and a ZK proof back it). Pay the Ethereum gas fee each time.
