@lunarbase-lab/pmm-v2-source-arbitrum

Arbitrum Nitro data source for the LunarBase client.

Status: maintenance. Updates focus on compatibility, reliability, and security fixes.

Install

npm install @lunarbase-lab/pmm-v2-math @lunarbase-lab/pmm-v2-client @lunarbase-lab/pmm-v2-source-arbitrum

Use

import { connect } from "@lunarbase-lab/pmm-v2-client";
import { ArbitrumNitroSource } from "@lunarbase-lab/pmm-v2-source-arbitrum";

const source = new ArbitrumNitroSource({
  httpRpcUrl,
  realtimeUrl,
  chainId: config.deployment.chainId,
});
const client = await connect(config, source, optionalCheckpoint);
const quote = client.quote(request);
await client.shutdown();

Behavior

• HTTP RPC provides bootstrap, backfill, and canonical recovery.
• A compatible Nitro HTTP endpoint must expose l1BlockNumber for every backfilled block.
• The realtime endpoint must include l1BlockNumber in newHeads notifications.
• Custom Fetch and WebSocket transports can be supplied by the application.
