Learn how to use custom EVM, SVM, or Cosmos chains in your application
Para supports a bring-your-own RPC model. This makes it easy to use Para with any network (at any stage), from internal devnets to any major mainnet network.
To use Para, you need an API key. This key authenticates your requests to Para services and is essential for integration. Before integrating Para with your application, ensure you have:
Need an API key? Visit the Developer Portal to create API keys, manage billing, teams, and more.
For Ethers, just provide the RPC URL for your desired chain
To configure a custom chain, just add a new Chain
type as follows
This chain configuration can now be passed to a viem provider
(See Docs)If you’re also already using wagmi, you can easily extend
@wagmi/chains
(Reference Docs) and automatically use Para
signers directly with your desired set of supported chains
Instantiate the Solana-Web3,js signer with your network’s RPC URL of choice
Initialize the signing client with your RPC URL of choice
Additional chains can be added by providing the relevant chain ID and RPC endpoint. See below for details:
