Descriptions

This is basic demo of using zksync L2 solution. This project contains 2 smart contracts. Contract on L1 (Ethereum) and contract on L2 that holds couter value and can be incremented via function. We can call increment function directly on from L1.

Contract deployed

ContractL1 (Goerli network): https://goerli.etherscan.io/address/0x2bD79B20d404F06bFF5e2Fe96E39dD65a37B7B7b

ContractL2 (zksync dev network): https://zksync2-testnet.zkscan.io/address/0xf0707436B2F9255DdCCeDbe7F3d3b735886DDBB5/transactions

Interact with contracts

Read couter value on L2

navigate to /L2 folder and run:

hh run scripts/read_value.ts

Following message should be displayed: The counter value is 1

Increment couter value via L1

navigate to /L2 folder and run:

hh run scripts/increment.ts

Following message should be displayed:
