Gattaca × Titan Builder

Strategic Design Partner · 2023 & 2026

Made Ethereum’s block-building and relay layer legible to the traders and validators who route through it. Titan now builds 53% of blocks.

→ The system

Titan Builder and Titan Relay have almost no consumer-facing surface: the design problem was behaviour, not screens. Ethereum’s block-building and relay layer decides which transactions get included, in what order, and who gets paid, under adversarial, real-time conditions. Good UX here is trust and predictability for traders, validators, and searchers who have to route real flow through a system they can’t see inside of.

→ What I owned

Owned the interaction and systems layer for both Titan Builder and Titan Relay at foundation (2023): translating adversarial, real-time block-building infrastructure into something traders, validators, and searchers could trust.

Built Gattaca’s institutional narrative, which was key to scale and fundraise.

→ The outcome

53%

of Ethereum blocks built, nearly 2.8× the next builder
