Answer2: That's true, it will only take as much as Arbitrum needs, which is usually around 0.05$. However, it is taking $2 for the transaction, which is still much lower than the usual transaction fees. This is because Arbitrum is designed to be a more cost-effective and secure blockchain platform. It uses a combination of advanced cryptographic techniques and off-chain scaling solutions to reduce costs and increase the speed of transactions. So, while it may not take exactly $3 for a transaction, it still provides a cost-effective and secure alternative to traditional blockchain platforms.
