The claim was accurate when written but events since have overtaken it.

   “Matcha is a decentralized exchange (DEX) aggregator developed by 0x Labs, a blockchain infrastructure company founded in 2016 by Will Warren (co-founder and CEO) and Amir Bandeali (co-founder and CTO).”

   reviewer0x Labs was founded in 2016 by Will Warren (co-founder and CEO) and Amir Bandeali (co-founder and CTO).The 2016 founding year and the identity of the two founders are correct, but by the page's own 'as of May 2026' timeframe the titles are outdated: Bandeali had already moved from CTO to Co-CEO, and around May 14-15, 2026 Warren stepped down from the CEO/Co-CEO role entirely to join the board while Bandeali became sole CEO.

   “Warren previously conducted research at Los Alamos National Laboratory and held a partial PhD in Structural Engineering from UC San Diego.”

   reviewerWill Warren conducted research at Los Alamos and held a partial PhD in Structural Engineering from UC San Diego.This sentence is true as far as it goes but omits Warren's completed B.S., which the page states elsewhere. Read against sections[3], which mentions only the B.S. and omits the PhD attempt, the two sections give an inconsistent and each incomplete picture of the same credential history.
