RNDR never swapped to RENDER
$17,750 · 1 positionMay not work
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.

MKR never converted to SKY
Maker / Sky
$172 · 1 positionMay not work
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.

KNCL never swapped to KNC
Kyber (KNCL)
$9 · 1 positionMay not work
You hold old KNCL tokens that were never swapped to KNC. The KNC token contract still accepts them.
1. Approve first: on the old KNC token (KNCL) 0xdd974D5C2e2928deA5F71b9825b8b646686BD200 call approve(spender = 0xdeFA4e8a7bcBA345F687a2f1456F5Edd9CE97202, amount).
2. Open the KNC contract 0xdeFA4e8a7bcBA345F687a2f1456F5Edd9CE97202 on Etherscan, Write as Proxy tab, and connect your wallet.
3. Call mintWithOldKnc(amount). It burns your KNCL and mints KNC 1 to 1.

Funds in old Ethereum contracts (2015-2021)
$7 · 1 position
You have a balance in an old Ethereum contract (The DAO, EtherDelta, IDEX, the 2017 ENS registrar, DigixDAO and others). Each contract has its own withdraw call. Use the wallet that owns the position.
1. The DAO: on the DAO token 0xbb9bc244d798123fde783fcc1c72d3bb8c189413 call approve(0xbf4ed7b27f1d666546e30d74d50d173d20bca754, yourBalance). Then call withdraw() on the WithdrawDAO contract 0xbf4ed7b27f1d666546e30d74d50d173d20bca754. It pays 1 ETH per 100 DAO.
2. EtherDelta 0x8d12a197cb00d4747a1fe03395095ce2a5cc6819: from the wallet that deposited, call withdraw(amount) for ETH or withdrawToken(token, amount) for a token. Amounts are in the token's smallest unit.
3. IDEX v1 0x2a0c0dbecc7e4d658f48e01e3fa353f44050c208: call withdraw(token, amount). Use token 0x0000000000000000000000000000000000000000 for ETH. It reverts if your last IDEX activity was fewer than 240 blocks ago.
4. 2017 ENS registrar 0x6090a6e47849629b7245dfa1ca21d94cd15878ef: call releaseDeed(labelhash) for the name. The labelhash is keccak256 of the name without .eth. The deposit goes back to the deed owner.
5. Other contracts (DigixDAO, Neufund and more): use the contract's own withdraw or refund function on Etherscan from the owner wallet. Check the contract's code first.

KEEP never swapped to T
Threshold (KEEP)
$6 · 1 positionMay not work
You hold old KEEP tokens that were never wrapped into T. The Threshold VendingMachine still does the swap.
1. Open the KEEP VendingMachine 0xE47c80e8c23f6B4A1aE41c34837a0599D5D16bb0 on Etherscan, Write tab, and connect your wallet.
2. First approve: on the KEEP token 0x85eee30c52b0b379b046fb0f85f4f3dc3009afec call approve(spender = the VendingMachine, amount). Amounts use 18 decimals.
3. Then call wrap(amount) on the VendingMachine to receive T. Threshold says there is no deadline.

FTM never moved to Sonic (S)
Fantom to Sonic
<$1 · 1 positionMay not work
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).

MATIC never swapped to POL
Polygon
$0 · 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.
