0xe450d38c: ERC20InsufficientBalance

error ERC20InsufficientBalance(address,uint256,uint256)

What it means

A transaction that reverts with the raw data 0xe450d38c hit the custom error ERC20InsufficientBalance, defined in OpenZeppelin 5. The explorer shows the hex because it does not have the contract's ABI to translate it.

The token transfer needs more tokens than the sender holds. The error data carries the sender, their balance, and the amount that was needed, so the shortfall is explicit.

How to fix it

Check the token balance against the amount, remembering decimals. If a contract triggered it mid-route, rebuild the transaction with a fresh quote.
