1. Polkadot 2017 sale DOT unclaimed

   Polkadot, Kusama

   $12 · 1 positionMay not work

   This Ethereum address bought DOT in the 2017 Polkadot sale, or got KSM in the 2019 Kusama drop, and never claimed it. You need the Ethereum wallet that bought it to sign one message.

   1. Follow the Polkadot wiki claims guide. In Polkadot-JS apps (Polkadot or Kusama), go to Developer > Extrinsics.
   2. Use claims.claim, or claims.claim_attest with the statement text if the row needs it.
   3. Sign the message with the Ethereum wallet that bought (personal_sign) and give a Polkadot account to receive. Part may be vesting-locked.

2. zkSync Lite balance not claimed

   $1 · 1 position

   zkSync Lite was shut down on 2026-05-04. Remaining balances are claimable on Ethereum through a claim contract and a withdrawal portal. Your account is on that list and has not claimed.

   1. Open the zkSync Lite withdrawal portal and connect the wallet that owned the account.
   2. The portal finds your address in the final state, builds the proof and sends the claim. Follow its prompts.
   3. Confirm the Ethereum transaction. Tokens go to your L1 address. Matter Labs sponsors gas for the first 100,000 withdrawals.

3. Expired Element Finance position

   <$1 · 1 position

   You hold Element v1 principal tokens (PT), yield tokens (YT) or pool shares. All tranches have ended, so they can be redeemed.

   1. Open the tranche contract (tranche_or_pool column) on Etherscan, Write Contract tab.
   2. PT: call withdrawPrincipal(amount, to). YT: call withdrawInterest(amount, to). Both only work after the tranche expiry.
   3. LP shares: exit the Balancer pool with exitPool first, then redeem as above.
