Why Use Catalyst
As a wallet or application developer, you will likely faces challenges with:
- Providing competitive pricing for cross-chain bridging and swaps
- Supporting multiple blockchains with minimal technical overhead
- Offering an industry-leading cross-chain user experience
Having a performant and seamless service for your users is fundamental to providing a memorable experience for your users.
Catalyst Advantages
The easiest way to resolve these challenges is by using an third party service like Catalyst. Compared to existing services, Catalyst provides several advantages:
Immediate Access to Competitive Pricing
By integrating with Catalyst, you gain access to our network of solvers who compete to offer the best rates for your users’ cross-chain transfers. This competition ensures your users consistently get favorable pricing without requiring you to manage liquidity sources.
Simple Integration
Catalyst is designed to work with common resource lock standards like The Compact. No custom development is required, significantly reducing the engineering effort needed to support cross-chain functionality.
Flexibility to Expand
As new blockchains emerge, you can easily expand your cross-chain support without compatibility concerns. Catalyst’s architecture allows you to add new chains without rebuilding your integration. Catalyst can be permissionlessly deployed to new chains.
Better User Experience
Your users benefit from:
- Gasless swaps
- Best-in-market fulfillment times
- A consistent experience across different blockchains
Integration Overview
Integrating with Catalyst involves three main steps:
- Implement resource locks – Use one of our supported standards (like The Compact)
- Connect to the order server – Broadcast user intents to our solver network
- Handle fulfillment callbacks – Process completed transfers
Our full integration guide provides detailed instructions, code examples, and best practices for implementing each of these steps efficiently.

Sub-Calls via Catalyst
By default, Catalyst supports calls on delivery. This allows you to schedule calldata to be executed after the delivery of assets, enabling more complex cross-chain operations.
The default output type of Catalyst, called OutputDescription, supports secondary calls through its remoteCall field, allowing for additional execution logic upon delivery.
