STRATEGIC ADVANTAGES
Business Outcomes: Why Build Your Own Block Builder
Building a custom MEV-Boost compatible block builder with Chainscore delivers measurable infrastructure control and revenue optimization, moving you from a passive validator to an active network participant.
01
Maximize MEV Revenue Capture
Directly capture and retain 100% of MEV rewards from your validator's block proposals. Eliminate reliance on public relay fees and third-party builder commissions, increasing your staking APR by 5-15%.

Frequently Asked Questions
Get clear answers on timelines, costs, and technical details for our custom block builder development service.
A standard decentralized block builder with core MEV capture and PBS support takes 4-8 weeks from kickoff to mainnet deployment. This includes 2 weeks for architecture and specification, 3-5 weeks for core development and internal testing, and 1 week for final integration and deployment. Complex features like cross-chain support or advanced auction logic can extend the timeline, which we scope and agree upon upfront.
