Asia is home to an estimated ~300 million crypto holders.
Crypto in places like Seoul, Tokyo, Singapore, and Hong Kong isn’t fringe. It’s just finance. And the biggest players in the region are choosing the OP Stack.
Asian financial institutions and crypto builders need infrastructure that:
◼️ Meets local regulatory requirements
◼️ Supports high trading volume
◼️ Plugs into Ethereum's liquidity and user base
The OP Stack lets them own the chain without building from scratch.
Who’s building on OP:
◼️ @GIWA_by_Upbit, being built by @Official_Upbit, South Korea's largest exchange with 13M+ registered users.
◼️ @mitsuiandco brought @zipangcoin, a precious metals backed token, to OP Mainnet.
◼️ @toss__official, Korea’s largest fintech super app, and @komsco, the Korea Minting, Security Printing, and ID Card Operating Corporation, just ran a full local-currency payment cycle on the OP Stack.
We’ll be on the ground at @kbwofficial and @token2049. See you there.

We’re helping small businesses get paid faster and save on transaction fees in South Korea.
@toss__official, Korea’s largest fintech super app, and @komsco, the Korea Minting, Security Printing, and ID Card Operating Corporation, just ran a full local-currency payment cycle on the OP Stack. This included loading funds onto a certificate, spending at a merchant, and settling. All in one single pass.
The Toss app bundles everything from payments to loans and insurance in one app, and has the majority of Korean adults onboard. With the help of KOMSCO, the government body that prints banknotes and coins, and the power of the OP Stack, crypto payments are coming to 🇰🇷

Enterprises need control. But that shouldn’t mean closing themselves off from the permissionless ecosystem.
At @rwasummit, VP of Sales Carlos Arena shared why staying connected to the wallets, infrastructure, and innovation happening onchain matters for what you might want to build next.
