What Is the Polkadot Cloud Builder Party?
The Polkadot Builder Party is a global hackathon and community movement bringing together developers, creators, and innovators to build the next wave of Web3 apps on Polkadot.
Running from October to November 2025, it features local meetups, online workshops, and a $40,000 prize pool, all designed to help teams turn ideas into production-ready projects using Polkadot’s powerful multichain infrastructure.
At its core, the Builder Party celebrates open collaboration and the growing vision of Polkadot as a true Web3 Cloud - a network where anyone can build, connect, and scale.
Supporting Polkadot Builders From Day One
From the very beginning, OnFinality has been all-in on Polkadot. As the ecosystem’s leading infrastructure provider, we’ve powered trillions of RPC requests + hundreds of indexers and validator nodes across all parachains and Substrate-based networks.
Our mission has always been simple: make it easy for builders to launch, scale, and succeed on Polkadot. That’s why we’re proud to support every participant in this year’s Builder Party with the tools they need to go from concept to production-ready.
Free Infrastructure for Every Builder 🚀
Every Polkadot Cloud Builder Party participant can unlock $200 in free infrastructure credits to build faster with OnFinality.

Polkadot Cloud Builders Party Calendar
🗓 Thursday, October 16th
🎤 Topic: AI x Polkadot Data
At this year’s Builder Party, we’ll explore how AI is becoming an integral layer of the Polkadot ecosystem
Key topics include:
- Orchestrating complex AI pipelines made up of multiple MCPs & Tools, Consulting Agents, & RAG
- Design consulting AI Agents — autonomous assistants that reason, query, and act across the Polkadot network
You’ll also get a live look at the OnFinality AI Agent, built in collaboration with SubQuery — a powerful framework that merges infrastructure, data indexing, and AI.
This is the next chapter of Polkadot: a network where AI understands, interacts with, and enhances blockchain activity in real time.
Calling All Builders - Create Polkadot MCPs for Smarter AI
The Polkadot Builder Party is the perfect place to explore a brand-new frontier: AI Model Context Protocols (MCPs) built for Polkadot.
MCPs are specialized AI plugins that allow intelligent agents to understand, query, and interact with Polkadot data and networks - powering everything from data analysis and validator recommendations to automated on-chain actions.
Developers can create MCPs that tap into SubQuery data sources, RPC endpoints, staking rewards, XCM transfers, or oracles - helping AI agents across the ecosystem gain real, actionable intelligence about the Polkadot network.
Teams participating in the Builder Party can request early access to the OnFinality Web3 Community AI Agent,to test and showcase their MCPs in a live environment. There is even a path for commercialisation of your ideas!

Let’s Build the Future Together
The Polkadot Builder Party is more than a hackathon - it’s a celebration of what’s possible when builders, infrastructure, and innovation come together.
At OnFinality, we’re here to power that progress every step of the way.
