🔁 Steps to Reproduce
- Open the Uniswap web UI with a fresh EOA.
- Enable Gasless transactions in settings (UI displays “Set up gasless transactions”).
- Approve the resulting transaction (UI sends a
setCode/ tx that installs code on the EOA).- Txn hash from setting EOA code: https://optimistic.etherscan.io/tx/0xc8a0ce4e2e701247fdae0a3f615fc2d26edec32dda5ca1b1ce87d16eb38e688a
- Try to perform any swap or even a 0-ETH self-transfer.
✅ Expected Behavior
- The UI should provide a clear “Disable / unset gasless transactions” button that removes the code.
- After disabling, the wallet should behave like a normal EOA again.
❌ Actual Behavior
- The UI installs code on the EOA.
- Subsequent transactions fail on multiple RPCs with
in-flight transaction limit reached for delegated accounts
- Self-call with 0 ETH (suggested fix) does not clear the code.
- Uniswap UI no longer allows swaps from this wallet; Foundry scripts (see below) also fail.

🧾 Additional Context
- I can't find any way to unset this contract code.
- First I verify the code is set:
$ cast code 0xC07E21c78d6Ad0917cfCBDe8931325C392958892 --rpc-url https://optimism.gateway.tenderly.co/xxx

uint256 pk = vm.envUint("PRIVATE_KEY");
address eoa = vm.addr(pk);
// Attempt 1: self-call to consume authority
vm.startBroadcast(pk);
eoa.call{gas: 1_000_000_000}("");
vm.stopBroadcast();
// Attempt 2: attach delegation to zero address
vm.signAndAttachDelegation(address(0), pk);
// Attempt 3: self-call again
vm.startBroadcast(pk);
(bool success, ) = eoa.call("");
require(success, "EOA code clear failed");
vm.stopBroadcast();
}
}Result:

Error: Failed to send transaction

Nothing clears the code. Please provide a supported method (or UI toggle) to unset / revert the EOA back to a plain account.
