10/Bottom line: Strong institutional backing (Upbit + Optimism), clear focus on identity + compliance, and real speed. One of the more purposeful L2s launching right now. What do you think- does the identity layer make GIWA interesting, or is it still just another OP Stack chain?

9/GIWA is still on testnet (GIWA Sepolia), but activity is already high. Mainnet is expected in H2 2026. It’s not trying to be the next degen playground. It’s trying to be infrastructure that actually connects everyday finance with Web3.

8/Who is GIWA for? Korean market - strict regulation, active retail, upcoming KRW stablecoin plans. Global builders - low barrier, familiar tools, and GASOK grants (up to $100k).

7/Why this matters: Apps can simply check if an address is “verified” and open features only for those users. Perfect for financial products that need compliance but don’t want users uploading passports to every dApp.

6/The most interesting part is Dojang. Dojang is an on-chain attestation layer built on Ethereum Attestation Service (EAS). It lets trusted issuers (currently mainly Upbit) confirm that a wallet has completed KYC - without putting any personal data on-chain.

5/Technical core: • Built on OP Stack • Fully EVM-compatible • 1-second block times • ETH as gas token (no native GIWA token planned) • Future Paymaster support for stablecoin gas fees (ERC-4337)

4/What that means in practice: Upbit runs the primary sequencer and controls key network decisions. Optimism provides monitoring, engineering support, and a backup sequencer. Full operational control + Ethereum security.

3/Why did Upbit need its own L2? By 2025–2026 every major exchange was building one: • Coinbase → Base • Binance → BNB Chain • OKX → X Layer Upbit followed. In May 2026 they signed an MoU with the Optimism Foundation and became the first Self-Managed OP Enterprise chain.

2/GIWA stands for Global Infrastructure for Web3 Access. The name also references traditional Korean roof tiles (“giwa”) - small pieces that together form a strong structure. That’s the vision: make blockchain infrastructure simple and usable for regular people.

1/GIWA is not just another OP Stack L2. It’s Upbit’s (Dunamu) attempt to build an Ethereum Layer 2 that prioritizes real accessibility, regulatory friendliness, and trust - not just speed and hype. Here’s a full breakdown.
