Polkadot Developers Conference // sub0 is the conference for developers building at every level of the Polkadot tech stack — from custom layer-1 blockchains to dApps and smart contracts, infrastructure, tooling, cross-chain interoperability solutions, and more.

In 2023 sub0 will return to Lisbon and is seeking funding from Polkadot Treasury. The last edition took place in LX-Factory in Lisbon on November 28th and 29th, 2022, Web3 Foundation, together with the teams of Apillon, Phala Network, Astar Network and Manta Network in representation of the entire Polkadot ecosystem brought together the global Polkadot developer community.

Sub0 will again provide an open introduction to next-generation multichain networks, as well as a chance for existing Polkadot and Substrate developers to deepen their skills and connect with each other. For this year's edition we want 50% of our audience to be new developers from outside of our ecosystem. This includes people who are not building on Substrate but are curious to learn more. By opening our doors to developers who are not (or only slightly) familiar with our tech, we can bring in more potential builders and expand our market reach and visibility. 

THIS IS THE FUNDING REQUEST FOR MILESTONE 1 AS PER THE BUDGET DETAILED IN THE DOC BELOW.
