IEUM
A Korean on-chain escrow that settles jeonse deposits, moving-day balances and gye circles in one transaction
It moves the moments when large sums change hands in Korea into escrow, starting with jeonse. Once the next tenant's deposit is locked in the contract, a single transaction on settlement day both returns the previous deposit and pays the balance. The money never passes through the landlord's hands, so the team argues there is nowhere for it to go missing.
When moving dates fall a few days apart, a bridge pool covers the gap. It only advances funds after the contract confirms the next tenant's money is already locked, making it very short-term liquidity against visible collateral, with the fee going to depositors. The same escrow primitive powers a gye circle: no organiser, an on-chain draw for the order, and missed payments deducted from the deposit. Contract documents are anchored as hashes.
The advance to GASOK Stage 3 was confirmed from the project's own post on 2026-09-10, which placed it in the DeFi and RWA sector. The site reports 40 of 40 Foundry tests passing.

Note: This is a demo on GIWA Sepolia testnet using mock won (mKRW); no real money moves through it. As checked on 2026-09-12 the jeonse contract (JeonseFactory, source verified) had one transaction and the other contract it uses had four.

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 five months or more. Phase 3 (Aug–Sep 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 slot at KBW 2026 Demo Day
- A $20K initial grant for the Demo Day winner, with more tied to later KPIs
