Expert Answers for Builders
PBS Consulting FAQs
Get clarity on our Proposer-Builder Separation consulting process, timelines, and outcomes.
A standard PBS integration for a new validator or relay service takes 2-4 weeks from kickoff to mainnet deployment. This includes architecture design, smart contract development, integration testing, and security review. Complex multi-relay setups or custom MEV strategies may extend the timeline, which we scope and quote for individually.
