1. dYdX v3 balance

   $40 · 1 position

   dYdX v3 was shut down and its exchange was set to 'frozen' on Ethereum. Your USDC can still be taken out through the escape hatch, or withdrawn if already released.

   1. Open dYdX's v3 sunset post and use the Escape Hatch link in its last update. It is hosted by an independent third party.
   2. Escape needs a proof for your stark key and position. The page builds it; the escape call goes to StarkPerpetual 0xD54f502e184B6B739d7D27a6410a67dc462D69c8.
   3. Then call withdraw from your registered Ethereum address to receive the USDC. You pay Ethereum gas.

2. Old Polygon Plasma bridge exit

   $2 · 1 position

   You withdrew from Polygon through the old Plasma bridge and the exit was never finished on Ethereum. Polygon's current docs no longer describe this bridge, so the route is not confirmed.

   1. Open Polygon Portal, connect the wallet that burned the tokens, and check Transactions for your exit.
   2. If Portal shows Initiate Claim or Claim Tokens, follow it and pay the Ethereum gas fee.
   3. If it is not listed, the exit must be run on the Polygon contracts directly. Ask Polygon support, with the burn transaction hash.

3. Balancer v3 pool share

   <$1 · 1 position

   You hold Balancer v3 pool tokens, in your wallet or staked. You can exit the pool. Under Balancer's wind-down proposal, the v3 Vault would pause on 30 Nov 2026, so withdraw before then.

   1. Open the Balancer app, find your pool and use Remove liquidity.
   2. If the pool is paused, anyone can call enableRecoveryMode(pool) on the v3 Vault 0xbA1333333333a1BA1108E8412f11850A5C319bA9. Then call removeLiquidityRecovery on the Router.
   3. If your tokens are staked in a gauge, Aura or Beefy, unstake there first.

4. 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.
