SDK
Type-safe clients for every stack.
Three first-party SDKs covering 95% of integrations. All open source, semantically versioned, and generated directly from on-chain ABIs.
Install
Works in browser, Node 20+, Bun, and Deno. Ships as ESM with `.d.ts` declarations.
MSRV 1.78. Async via Tokio. `serde`-compatible types throughout.
Python 3.11+. Sync and async APIs. Native pandas DataFrames for analytics queries.
Quickstart
import { RivrClient } from "@rivr/sdk";
const rivr = new RivrClient({
rpc: process.env.RPC_URL,
});
const apr = await rivr.staking.currentApr();
console.log(`APR: ${apr}%`);use rivr::Client;
#[tokio::main]
async fn main() -> anyhow::Result<()> {
let rivr = Client::new(&std::env::var("RPC_URL")?)?;
let apr = rivr.staking().current_apr().await?;
println!("APR: {apr}%");
Ok(())
}from rivr import RivrClient
rivr = RivrClient(rpc=os.environ["RPC_URL"])
apr = rivr.staking.current_apr()
print(f"APR: {apr}%")Modules
