Developer Overview

Developer Overview

XDEX is a Solana and X1-native decentralized exchange powered by a custom Automated Market Maker (AMM) and aggregator integration.

🔧 AMM Architecture

XDEX’s AMM smart contract is a modified and modernized fork of Raydium's swap program, adapted to include:

• A flat fee logic (0.28%) unified across AMM and aggregator swaps

• Simplified vault-based reward routing

• Native compatibility with both Solana and X1 blockchains

• Support for Swap-to-Earn and on-chain real yield tracking

We’ve retained Raydium’s proven architecture where appropriate and introduced targeted upgrades for:

• Cleaner program logic

• Flexible fee allocation

• Improved reward transparency

• DAO-controlled emission redirection after rewards end

🔀 Aggregator Routing

XDEX’s routing layer integrates directly with the Jupiter aggregator:

• Solana: via Jupiter’s open routing system

• X1: custom routing module forked and extended from Jupiter’s Metis engine

The aggregator system supports:

• Dynamic route discovery

• Best-price execution

• Revenue fee tracking (0.05%) redirected to the USDC rewards vault

💡 Why Fork Raydium?

Raydium’s battle-tested AMM structure offers deep composability and reliability. By selectively forking and extending it, XDEX ensures:

• Compatibility with existing Solana tooling

• Proven performance under load

• Easier developer onboarding

Our enhancements simplify long-term token alignment and reduce technical debt.
