South Korea’s largest cryptocurrency exchange, Upbit, has partnered with the Optimism Foundation to build Giwa Chain, a new Ethereum-based Layer 2 blockchain network.

 

Giwa Chain, which will be built on Optimism’s open source OP Stack, will be the first of its kind built on the self-managed tier of Optimism’s OP Enterprise and stems from the growing need for exchanges to build their own blockchains.

 

 

While crypto exchanges using shared chains are not inherently problematic, issues arise as usage increases, making it difficult for these networks to handle the growing workloads of exchanges, including institutional transaction volumes, compliance requirements, and fee economics, which often compound as an exchange scales. For a global exchange like Upbit, which serves more than 13 million users and ranks among the top exchanges by spot trading volume, owning and managing its own blockchain is critical for performance and scalability.

 

By partnering with Optimism to build a self-managed chain, Upbit allows Optimism to manage key technical aspects of the chain’s infrastructure, including tooling and engineering support, while still retaining sovereignty over the chain’s control and overseeing key functions such as the primary sequencer, chain configuration, and operational authority.

 

“Operating our own Giwa Chain is a strategic move for Upbit. Our goal is to provide institutional and retail users with a level of performance and compliance consistent with our existing platform,” said Minseok Jung, Chief Operating Officer of Dunamu Inc.

 

“The Optimism Foundation’s self-managed tier provides a suitable framework, allowing us to maintain operational control while building on established infrastructure. This approach aligns with our requirements for scalability and oversight.”

 

Giwa Chain is currently live on testnet, with mainnet deployment to follow. Dunamu, the parent company of Upbit, has also signed a memorandum of understanding with the Optimism Foundation on May 4, outlining key aspects of Giwa Chain, including its architecture reviews, performance benchmarking, and security audits.

 

Crypto Exchanges Building Their Own Chains

There has been an increase in the number of cryptocurrency exchanges building their own layer 2 blockchains, with many doing so for improved infrastructural performance and to gain control over fees, transaction sequencing, user experience, and compliance.

 

The OP Stack has been instrumental in this development, with the Optimism Foundation stating that its OP Stack currently houses over 32 layer 2 blockchain networks, including Binance’s opBNB chain, Kraken’s Ink chain, Gate.io’s Gate Layer, and OKX’s X Layer.
