About GIWA
In September 2025, the GIWA testnet (Giwa Sepolia) launched, built on the with one-second block times, aiming to provide fast, low-cost Ethereum Layer 2 infrastructure.
In April 2026, the team announced the migration of the execution client from op-geth to op-reth, following the OP Stack ecosystem's transition, with plans to move to kona-client at the Karst hardfork, ensuring long-term node support.
Key GIWA Chain progress in the past six months: On May 4, 2026, Upbit parent Dunamu signed an MoU with the Optimism Foundation at Consensus Miami, planning GIWA Chain as the first chain on OP Enterprise's Self-Managed tier, with Upbit running the primary sequencer and the Foundation providing backup and monitoring. From May 31, op-geth support ended, requiring node migration to op-reth; the Fault Proof program shifted from op-program to kona-client. On July 6, the testnet (Sepolia) activated the Karst hardfork (Upgrade 19), introducing Osaka EVM features, the L2CM contract management mechanism, OPCMv2, and the CANNON_KONA dispute game type. The ecosystem launched Giwa Wallet, Dojang on-chain verification, Bojagi privacy protocol, UP.ID naming service, and the GASOK developer support program. Future focus: mainnet launch, Karst mainnet upgrade, interop interoperability via L2CM, and global developer ecosystem expansion.
