1. MKR never converted to SKY

   Maker / Sky

   $8,683 · 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. MATIC never swapped to POL

   Polygon

   $305 · 1 position

   You hold old MATIC on Ethereum that was never swapped to POL. The swap is 1 to 1. Polygon has not announced a deadline.

   1. Open the Polygon Portal upgrade page and connect your wallet. Switch the wallet to Ethereum.
   2. Approve the upgrade contract to use your MATIC.
   3. Confirm the migrate transaction to receive POL. You pay Ethereum gas.

3. Funds in frozen StarkEx apps

   Sorare, Immutable X, ApeX Pro, edgeX v1, Myria

   $18 · 1 positionMay not work

   Some StarkEx apps keep balances off-chain. A pending withdrawal can be claimed now. A deposit-only record cannot: the app operator must first publish data.

   1. Check the row type. A pending withdrawal can be claimed now; a deposit ledger row cannot.
   2. For a pending withdrawal, call withdraw with your owner key and asset type on the app's StarkEx contract (Etherscan). Funds go to your registered address.
   3. For a frozen app, the escape hatch needs the operator or data committee to publish state first. See the StarkWare docs.
