1. MATIC never swapped to POL

   Polygon

   $71 · 1 positionMay not work

   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.

2. MKR never converted to SKY

   Maker / Sky

   $30 · 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.

3. Balancer v1 or CoW AMM pool share

   $6 · 1 position

   You hold tokens of an old Balancer v1 pool or a Balancer CoW AMM pool. There is no Balancer app for v1, but you can leave the pool through the contract.

   1. Open the pool address (pool column) on the block explorer, Write Contract tab.
   2. Call exitPool(poolAmountIn, minAmountsOut) with your pool token amount. Use zeros for the minimums only if you accept any price.
   3. If your tokens are staked elsewhere, withdraw them there first. Balancer also publishes an open-source exit tool: github.com/balancer/exit-ui (no hosted copy was online on 2026-10-01).
