Sequencer API

The Sequencer API enables developers to interact with RibbleChain's Layer 3 (L3) rollup sequencers, which batch and process transactions before submitting them to the Layer 1 (L1) for settlement. This guide provides detailed instructions for using the Sequencer API to manage rollup transactions, monitor performance, and integrate with dApps.

Overview​

RibbleChain's Sequencer-as-a-Service allows L3 rollups to operate custom sequencers tailored to specific use cases (e.g., GameFi, DeFi). The Sequencer API provides endpoints for:

  • Submitting transactions to the sequencer.
  • Querying rollup state and transaction status.
  • Configuring sequencer parameters (e.g., batch size, finality).

Prerequisites​

  • A deployed L3 rollup (see Getting Started with L3 Rollups).
  • RibbleChain CLI: npm install -g ribblechain-cli.
  • Access to the testnet RPC: https://testnet.ribblechain.com.

Step 1: Set Up API Access​

Authenticate with the Sequencer API using an API key:

ribblechain-cli api init --rollup my-rollup
