Base builder #001 (self-described) | Creator of Base (public framing) | Coinbase




Jesse Pollak is the Coinbase engineer publicly identified as the creator of Base - the Coinbase-incubated Ethereum L2 that became one of the highest-throughput L2s and the settlement layer for a large part of the USDC / onchain-app economy. He is the public face of Base in founder circles (self-described 'Base builder #001') and is the key Coinbase-side node for Base-native products and x402-style payment rails. Address/identity edge: jesse.base.eth. This node keeps only what is publicly stated - no invented job title beyond the self-described 'Base builder #001' and the widely published 'creator of Base' framing. In the 2026-02-25 X thread he appears in the same San Francisco / Coinbase HQ frame as Geoffrey Woo and the Anti Hunter agent, with an $UM-Radar dossier promised by @alexdolbun.
