Market makers (propAMMs)
If you operate a proprietary AMM (propAMM), stream your quote updates to BuilderNet as priority updates. Depending on the mode set for your API key, the builder places an update at the top of the block or includes it only when a transaction in the block emits a consumption event registered for your key. Updates are sent over WebSocket and go through the Priority Update Registry. API keys are issued on request; message the team on Telegram (see below).
Aggregators and solvers that route against propAMM liquidity can read the pending quote state from the quote stream. No key is needed.
Developers
Contribute to rbuilder, the open source block builder that BuilderNet's builder is derived from. Join the conversation in the Telegram group.
Researchers
Contribute to the security and design of decentralized block building through initiatives like zero trust execution environments, applications of software cryptography in MEV (eg. MPC, FHE), and more on our research forum. Apply for grants from teams like Flashbots and the PBS Foundation to research new proposals like TEE-Boost. We are interested in establishing robust benchmarks for decentralization that can be used to measure BuilderNet’s progress and bring transparency to the community, and welcome input on the forum.
