Issue Description

I am trying to bridge my erc20(simple erc20 token) from sepolia(0x40e3c945e37c8a3c2d1bc060ba6af9b84885463e) to base sepolia however i have not been able to successfully do this. I have an erc20 on sepolia and IOptimismMintableERC20 created using IOptimismMintableERC20Factory on base(0x86bb5ff3413f795a7a70a1ca33e2e903a41ba6b0). After approval when i am using L1Standard bridge to transfer the erc20, its giving some reverr errors which i am unable to understand and solve. This is the last one i tried today but still unsuccessful -

you used the wrong L1 standred bridge contract, 0xFBb0621E0B23b5478B630BD55a5f21f67730B0F1 is op sepolia contracts, not base sepolia https://docs.optimism.io/superchain/addresses#sepolia-l1

[opfocus]

https://sepolia.basescan.org/address/0x578aea18a73a283b9f7c702bab3e22c7ad8f5fbd#tokentxns it's successful

Awesome you are right i am seeing the balance. I triad another transaction and balance is reflected. Seems like there is 5+ minute delay. I had one more question. The transactions are showing error with revert. Is this expected if not how can this be fixed. Also how are transactions succeeding even with the error?

Below is the error from the 2 transactions which ended up updating balance on sepolia:

Although one or more Error Occurred [execution reverted] Contract Execution Completed

This is normal. This comes from historical reasons. The op team found a bug but encountered difficulties in finding the direct cause. Eventually they came up with a less than perfect solution https://blog.oplabs.co/the-highly-optimistic-dev-blog-01-the-mystery-of-the-missing-message/

Thank you. I was trying the withdraw from base sepolia to sepolia back. The transaction seems successful

L2 Bridge Address - 0x4200000000000000000000000000000000000010
L2 ERC20 Optimism Bridge Token - 0x86bb5ff3413f795a7a70a1ca33e2e903a41ba6b0
Parameters for withdraw called on L2 Bridge Token - 0x86bb5ff3413f795a7a70a1ca33e2e903a41ba6b0, 1000000000000000000, 200000, 0x

I see the token deducted from L2 base sepolia wallet however i dont see the same credited to L1 Sepolia wallet. Can you help me with what might be the issue

[opfocus]

It is recommended that you read the part about bridge in the docs, because withdrawal needs to go through several processes, and it is best to use the relevant sdk

This may take you more than 7 days at the earliest
