Matchain Contracts

L1/L2 system contracts

System contracts on Layer1 and Layer2 are an important part of the OP ecosystem. 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
