This is a standalone class that can be dropped into any frontend or backend Web3 project.

If you’re looking for a reliable, no-nonsense solution in this category, w3dr is definitely worth a shot.” This is a standalone class that can be
const response = await fetch(url, method: 'POST', headers: 'Content-Type': 'application/json' , body: JSON.stringify(payload), signal: controller.signal );
: In this context, w3 refers to the specific weight assigned to DR , which stands for Reliability . // Use 'race' strategy for fastest UI response
// Use 'race' strategy for fastest UI response times const w3dr = new W3DR(rpcUrls, strategy: 'race' );

/** * The main method to send RPC requests. */ public async request(method: string, params: any[]): Promise<any> const payload = jsonrpc: "2.0", id: Date.now(), method, params ;
Despite extensive research, the origins of W3DR remain unclear. There is no concrete evidence to pinpoint the creation date, author, or purpose of W3DR. It is possible that W3DR emerged as a grassroots initiative or a meme, spreading organically through online communities.
