Ripple (XRP) Improvement Proposal: Federated Sidechains for the XRP Ledger

·

Overview

On June 7, 2021, Ripple CTO David Schwartz proposed Federated Sidechains for the XRP Ledger (XRPL) to enable smart contract functionality while minimizing mainnet strain. This initiative addresses developer demand for expanded DeFi and programmable asset capabilities.

Background

To preserve XRPL’s efficiency, Ripple’s team designed a federation system linking the mainnet to independent sidechains. This architecture balances innovation with stability by isolating experimental features from the core ledger.

Key Components

Implementation Strategy

  1. Develop Federator Infrastructure: Core software enabling cross-chain communication.
  2. Minimal Mainnet Adjustments: Two minor code changes to support sidechain logic.
  3. Sidechain-Specific Features: Extended XRPL server capabilities (disabled on the mainnet).

Advantages

Developer Flexibility

Low-Risk Upgrades

Continuous Innovation


FAQs

What are Federated Sidechains?

They’re independent blockchains connected to the XRP Ledger via Federators, allowing asset transfers and experimental features.

How do smart contracts benefit XRPL?

Smart contracts (👉 self-executing agreements) enable trustless DeFi protocols, automated payments, and more—without overloading the mainnet.

Can sidechains have their own tokens?

Yes, sidechains may issue native assets traded on XRPL’s decentralized exchange.
