GIWA denies claims that its mainnet RPC has been leaked, stating that the mainnet of this Ethereum Layer 2 network has not yet been launched.

• GIWA indicates that its mainnet has not yet been released, therefore it is impossible for any leaks to occur involving the already launched mainnet RPC.
• The official documentation only lists the GIWA Sepolia testnet and RPC endpoints; the mainnet infrastructure is still under development.
• GIWA runs on OP Stack and uses Ethereum as the transaction settlement layer.
• GIWA Wallet and stablecoin ecosystem products are still labeled as “Coming Soon” on the project website.
• Upbit previously collaborated with Optimism to build GIWA using an independently managed OP Enterprise infrastructure model.

On September 27th, the project stated on X that since the mainnet has not yet been launched, it is impossible for any RPC leaks to occur on the mainnet. GIWA also reminded users of DYOR and advised them to be vigilant against false information and scams that may circulate before the launch.

The official documentation for GIWA also supports this claim. The mainnet portion of the network is still marked as 'under development', while GIWA Sepolia can be used as a public testing environment.

GIWA The mainnet is still under development.

The documentation for GIWA does not provide access to the mainnet RPC endpoint. Instead, developers can access the GIWA Sepolia testnet through sepolia-rpc.giwa.io. There is also a Flashblocks test endpoint that can be used for faster transaction pre-confirmation.

According to the project's network guidelines, both endpoints have rate limiting and are only intended for development and testing purposes. GIWA clearly indicates that its mainnet "is still in development at present."

The same distinction can also be seen in the smart contract documentation of GIWA. The contract page lists the contracts that have been deployed on the Sepolia testnet, but the mainnet section is still marked as under development.

Another Flashblocks document lists an available test network endpoint, while marking the corresponding main network endpoint as “coming soon.”

Therefore, the existing documentation supports the statement of GIWA: the public test network already exists, while the production network has not yet been launched.

This clarification stems from claims on social media regarding the so-called "mainnet RPC leak." GIWA did not identify the accounts or websites behind these claims in the statement obtained for this report.

The information provided by GIWA does not indicate that its Sepolia test network RPC has been compromised. The project's response specifically addressed claims related to the mainnet, which has not yet been launched.

GIWA uses OP Stack to build Ethereum Layer 2

GIWA is an Ethereum Layer 2 built using OP Stack; OP Stack is an open-source software framework maintained within the Optimism ecosystem.

According to its technical documentation, the block generation time for this network is 1 second, and it is compatible with Ethereum virtual machine development tools. Developers can use common tools used in Ethereum development to deploy the Solidity contract.

This network uses a sorter for block generation, while Ethereum provides an environment known as Layer that supports the GIWA settlement architecture. The current design sets a maximum of 60 million blocks per gas, with a block interval of 1 second.

Unlike some Layer networks, GIWA is not currently promoting a separate native token. As FAQ writes, ETH is used as the underlying asset and for transaction fees, and in the future, it may be possible to pay transaction fees with stablecoins through the support of the Paymaster system.

The participation of Upbit was made public earlier in 2026. Reports stated that Upbit collaborated with Optimism to build GIWA using OP Stack according to the level of Self Managed OP Enterprise.

It is reported that this arrangement allows Upbit to autonomously manage the infrastructure, while also receiving technical support and failover services provided by Optimism. Control over the sorter means that the operator is responsible for sequencing transactions on the network.

GIWA's own documentation describes this chain as being 'supported by Upbit', and positions it as the infrastructure that connects users, developers, and liquidity with Web3 applications.

GIWA Wallet and stablecoin products are still not completed.

According to the public website of GIWA, several planned products have not yet entered the official release stage. The official website labels GIWA Wallet as “Coming Soon”. The introduction states that this is a self-managed product designed for GIWA Chain, which supports multiple chains and allows for integrated viewing of exchange assets.

The planned stablecoin ecosystem is also in the same state. GIWA indicates that support is planned for payments involving the Korean won and global stablecoins, and it includes the Paymaster infrastructure that may allow stablecoins to cover transaction fees.

Currently, the project mainly encourages developers to use its test network. Developers can obtain the test ETH and use the GIWA Sepolia before the official deployment to conduct smart contract, wallet integration, and other tests.

The smart contract development guide for GIWA supports Foundry, Hardhat, and Remix IDE. Since this network follows the Ethereum execution environment, applications can use Solidity or other tools compatible with EVM.

Node documentation also provides similar test-oriented settings. Developers can run their own GIWA nodes or use the free Sepolia RPC endpoints, although it is recommended that future production environment workloads use external node services.

Upbit Continuing to advance the construction of blockchain infrastructure

GIWA is part of Upbit's efforts to expand its business and move away from centralized exchange trading.

The project website lists on-chain identity, data oracle services, wallets, and stablecoin payments as part of its planned components. As GIWA moves towards the production network, some of these are still in the development stage.

Upbit has also previously made clarifications regarding reports on unreleased blockchain products. In July, it was reported that the exchange denied involvement in the issuance of Open USD, and the reason was that Dunamu appeared on a list related to that stablecoin project.

At that time, Upbit indicated that they did not agree to issue or launch this stablecoin denominated in US dollars. Several other Korean companies mentioned in the same plan also denied having made any formal commitments.

GIWA This time, the scope of clarification is narrower, only involving technical statements regarding the RPC endpoint, and it indicates that the GIWA mainnet has not yet been launched.

The project's public documentation does not provide a mainnet launch date. Its links, contracts, and the Flashblocks page still indicate that the mainnet features are in development or about to be launched.
