Notes for zkSync Era API

zkSync Era nodes employ a JSON-RPC specification, a standard communication protocol enabling remote operations to function as if they were local. However, due to their alpha status, they may sometimes experience issues or downtime.
Developers like yourself can use the zkSync Era API to interact with the zkSync blockchain and develop applications for it. To interact most effectively with the zkSync Era API, developers are encouraged to use Web3 libraries—web3.js for those utilizing JavaScript, and web3.py for Python users.
If you come across any discrepancies from the main node API, please report them directly to Matter Labs.
