TEAM
Security people who build products.
EX5 was founded by engineers from cybersecurity and software security. The team is small on purpose, works across all five products, and puts its names on the door — not an anonymous protocol.

HOW WE WORK
One team, five products.
Engineers move between the exchange, the wallet, payments and the GPU platform. Ownership is by product, standards are shared.
01
Security is everyone's job
Threat modelling in every design review; nothing ships without a security pass.
02
Own the stack
Our matching engine, our GPUs, our models. Fewer vendors, fewer surprises.
03
Publish receipts
Burns on-chain, invoices public, status page honest. Internally the same: written decisions, open metrics.
04
Remote-first, four languages
EN · TR · RU across engineering and support; async by default.
