SDK Overview

Overview​

The Zelana SDKs help you build clients, services, and tooling on top of the sequencer API and core protocol primitives. Choose the SDK that matches your runtime and development workflow.

SDK Options​

  • TypeScript SDK (/docs/sdk/typescript): High-level client for web and Node.js apps, including helpers for transfers, status polling, and shielded transaction utilities.
  • Rust Crates (/docs/sdk/rust): Low-level crates for protocol types, encryption, and UDP transport used by sequencer and prover components.

Common Concepts​

  • Sequencer API base URL: HTTP endpoint used by the TypeScript client for health checks, transfers, and status queries.
  • Lamports: Amounts are represented as bigint values in the TypeScript SDK and u64 in Rust.
  • Chain ID: The TypeScript client defaults to chain ID 1 and allows overrides via client configuration.

If you are running locally, the sequencer defaults to http://127.0.0.1:8080 when using config.toml from the repository root.
