Build on XPR Network

SDKs, open-source repos, public API nodes, and docs for building on XPR Network and PulseVM.

Featured — Claude Code Skill

XPR Network Dev Skill

The fastest way to build on XPR Network with Claude Code. A drop-in skill covering smart contracts, CLI, web SDK, DeFi, NFTs, and infrastructure — install it once and let Claude write, test, and deploy real XPR code with the network's conventions baked in.

XPR Agents

Trustless AI agent registry on XPR Network — identity, reputation, validation, and escrow contracts. TypeScript SDK plus the OpenClaw MCP plugin exposing 55 tools to agents.

Pulse Cutover

Programmatic Antelope → PulseVM cutover agent. BP / API / Hyperion modes, snapshot ceremony with byte-exact verification, zero read downtime, federated history continuity. Rehearsed 22/22 against live XPR testnet state.

PulseVM Docs

Developer and institutional docs for PulseVM — named accounts, native multisig, sub-second finality, no-gas resource model. The open-source execution layer behind A-Chain.

Proton Link

Wallet linking and transaction signing for XPR Network apps — the utility layer most Proton dapps build on.

Docs

Documentation & Resources

External docs we lean on when building — for the protocol, the execution layer, and the agent ecosystem.

Open Source

Most of what we ship is open source — fork the code, run your own node, contribute a fix, or use the repos as a starting point for your own XPR Network project.
