Starknet Snap API

When connected to the Starknet Snap, dapps can use the Starknet Snap API to interact with users' Starknet accounts (for example, to send transactions).

The examples on this page use the wallet_invokeSnap JSON-RPC method, which supports all Starknet Snap API methods.

note

We recommend using EIP-6963 for detecting the MetaMask wallet when using the wallet_invokeSnap approach. This ensures better interoperability and improved wallet integration.

note

You can also communicate with the Starknet network using the Starknet API.

Supported networks

Starknet currently supports two public networks. Use these networks' chain IDs with the Starknet Snap API methods.

Network	Chain ID (Hexadecimal)
Mainnet	0x534e5f4d41494e
Testnet (Sepolia)	0x534e5f5345504f4c4941
