Learn, build, and connect on all things Substrate

Sub0 Online brings together Substrate developers and learners of all experience levels for two days of in-depth talks and workshops on the blockchain framework for building custom Polkadot-compatible blockchains.

Hear from Gavin Wood, the core developers behind Substrate, as well as teams building innovative Web3 projects using the blockchain framework.

The multi-track event will have something for everyone, whether you’re new to Substrate and want to understand its potential or are an experienced builder looking to take your project to the next level.

Get the latest insights into Substrate and the future of the ecosystem, improve your technical skills, and leave inspired from connecting with like-minded Web3 builders.
