Providers for SFA JS SDK

Providers are basically pre-configured RPC clients for different blockchains. They are used to interact with the blockchain network. Web3Auth provides you with a few common providers for the most commonly asked chains. In case of SSS-based private key providers, you can also use the private key of the user to connect to other blockchain networks.

Currently, Web3Auth supports the following private key providers:

Private Key Providers

• EIP1193 Private Key Provider for EVM Compatible Chains
• Solana Private Key Provider for Solana Blockchain
• XRPL Private Key Provider for XRPL Blockchain
• Common Private Key Provider for Connecting to any Blockchain

Base Type Reference for Web3Auth Providers

For facilitating these providers, Web3Auth exposes a IProvider which is a provider type helping you make standardized RPC calls to a blockchain.

This provider contains two functions, send and request. You can find its type reference below:

export interface IProvider extends SafeEventEmitter {
  sendAsync: <T, IProvider=> Promise<U>;
  send: <T, U>(req: JRPCRequest<T>, callback: SendCallBack<U>) => void;
  request: <T>(args: RequestArguments) => Promise<Maybe<T>>;
}

export interface JRPCRequest<T> extends JRPCBase {
  method: string;
  params?: T;
}
export interface JRPCBase {
  jsonrpc?: JRPCVersion;
  id?: JRPCId;
}
export declare type JRPCVersion = "2.0";
export declare type JRPCId = number | string | void;
export interface RequestArguments {
  method: string;
  params?: unknown[] | object;
}
