Struct ERC20InsufficientBalance 

pub struct ERC20InsufficientBalance {
    pub sender: Address,
    pub balance: U256,
    pub needed: U256,
}

OpenZeppelin v5 ERC20: the spender’s balance is below the transfer amount. openPool’s safeTransferFrom bubbles this up verbatim when the node’s USDC balance cannot cover the deposit. Custom error with signature ERC20InsufficientBalance(address,uint256,uint256) and selector 0xe450d38c.

error ERC20InsufficientBalance(address sender, uint256 balance, uint256 needed);

Fields

sender: Address

balance: U256

needed: U256
