What is Starknet.js?

Starknet.js is a way to connect your website or your Digital Application (DAPP) to the blockchain-based Starknet network, using Javascript/Typescript language.

Overview :

Some important topics that have to be understood:

• You can connect your DAPP to several networks :

  • Starknet mainnet (Layer 2 of Ethereum network ).
  • Starknet testnet 1 & testnet 2 (Layer 2 of Goerli network (testnet of Ethereum)).
  • Starknet-devnet (your local Starknet network, for developers).

  and also to some more specific solutions :

  • a private customized version of Starknet.
  • local Starknet node (connected to mainnet or testnet).

• Only the Provider object is talking directly to the network; your DAPP will talk mainly to Account and Contract objects. You will define with the Provider which network you want to work. You can ask the Provider for some low-level data of the network (block, timestamp, ...).

• Signer and Utils objects contain many useful functions for the interaction with Starknet.js.

• The Contract object is mainly used to read the memory of a blockchain contract.

• The Account object is the most useful :

  • as a wallet, to store your tokens.
  • as a way to pay the fees to the network, to be able to write in its memory.
