Custos Finance
RWA exchange
Custos Finance says it is building a proof-first RWA exchange. Asset context and proof should be visible before any market action, rather than listing first and proving later.
On 2026-08-28 the team published a GIWA Sepolia testnet prototype video, called it the last round of testing, and said it is moving from testnet toward private mainnet.
The website announced the same day was only marked as coming soon at the time, but as of 2026-09-24 it is open as a public testnet on GIWA Sepolia. One terminal covers real-world assets, spot markets and perpetuals, with synthetic exposure to gold, silver and oil. The screens carry a note that these synthetic assets have no cash value, and no move to private mainnet has been announced.

Based on a public statement by the project itself or a credible third party. GIWA has never published an official roster. Phase 3 is also an ongoing stage, so this means admission to it rather than completion.
What is GASOK Phase 3?
GASOK is Dunamu and Upbit's builder program for GIWA, an incubation running seven months or more. Phase 3 (Aug–Nov 2026) is the "market readiness & launch" stage, aiming at testnet user metrics and a private mainnet deployment. There are five tracks: DeFi/RWA, Consumer/Social, GIWA-Native, AI/Web3, and Mass Adoption.
What teams admitted to GASOK Phase 3 receive
- Engineering and productization support from the GIWA team, plus industry advisors
- Seoul office space if needed, and press and media support
- A shot at the KBW 2026 Showcase (the top team in each track, five in all)
- A $20K grant if picked at the Finalist Demo Day (date not yet announced), then up to $80K more tied to KPIs
