1. Dfyn Network LP tokens

   $18 · 1 position

   Dfyn Network is a closed exchange. Your liquidity-pool (LP) tokens still give a share of the tokens in the pair contract. The website is gone, so you use the contracts directly.

   1. Find the pair contract in the 'pair' column of your row. If your LP tokens are staked in a farm, withdraw them there first.
   2. Approve the LP tokens to this exchange's old router contract, then call removeLiquidity on it in the explorer's Write tab.
   3. Never send LP tokens to the pair by hand: anyone can call burn first and take them. If no router works, ask a developer.

2. MATIC never swapped to POL

   Polygon

   $12 · 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. Iron Finance IS3USD LP tokens

   Iron Finance (IronSwap IS3USD, Polygon)

   $1 · 1 position

   Iron Finance IS3USD is closed, but its stable-coin pool contract still works. Your LP tokens give you a share of the coins in the pool.

   1. If your LP is staked in IronChef 0x1fd1259fa8cdc60c6e8c86cfa592ca1b8403dfad, call withdraw(0, amount, to) there first (Polygon explorer, Write tab).
   2. Then on the pool 0x837503e8a8753ae17fb8c8151b8e6f586defcb57 call removeLiquidity(amount, minAmounts, deadline) or removeLiquidityOneToken(amount, index, minAmount, deadline).
   3. Set minimum amounts you accept. Pay the network fee in POL.
