+The [ZKsync Era smart contracts](https://github.com/matter-labs/era-contracts/tree/main/l1-contracts/contracts)
 allow a sender to request transactions on Ethereum (L1) and pass data to a contract deployed on ZKsync Era (L2).
 
-In this example we'll send a transaction to an L2 contract from L1 using `zksync-ethers`, which provides helper methods to simplify the process.
