Contract Metadata
L1/L2 system contracts
System contracts on Layer1 and Layer2 are an important part of the OP ecosystem. Since our RaaS is using OP Stack, we're using these system contracts to do the following tasks:
- Sending messages between L1 and L2
- Sending tokens between L1 and L2
- Querying information about the current L1 data fee
- And lots more
