Introduction

Welcome to the XYO Layer One Developer Documentation!

As a developer, you’re invited to build with us on the XYO Layer One Blockchain — our new infrastructure for secure, scalable, and verifiable data interactions. Whether you’re testing smart contract logic, experimenting with real-world data flows, or deploying early dApps, this documentation will guide you through connecting to our Testnet and beginning your journey with XYO.

The current version of this documentation supports the XYO Layer One Testnet, codenamed Sequence. To get started, you’ll need XL1 Testnet tokens, which allow you to interact with the network, test transactions, and validate dApp behavior in a risk-free environment. These tokens are freely available for developers participating in the early Testnet phase.

Inside, you’ll find step-by-step instructions to:

• Connect to the Testnet network

• Deploy contracts and data validators

• Use sample data from real-world Bound Witnesses

• Contribute feedback and improvements to the ecosystem

We’re building a new kind of data blockchain — one rooted in real-world verification, developer freedom, and decentralized trust. Whether you’re here to test, build, or explore, we’re excited to have you on this journey with us.

Stay tuned for upcoming features, grant programs, and tools to help accelerate your development on XYO Layer One.
