OK Cashbag members, nearly half the South Korean population, transitioned onto AvaCloud-managed L1 infrastructure with no disruption to the existing experience.
How SK Planet brought Korea's largest loyalty program, 21 million members strong, onchain.

South Korea's largest information and communications technology platform didn't ask its 21 million OK Cashbag members to learn Web3. It rebuilt the loyalty program underneath them, and they kept earning points.
New users signed up in the first 48 hours after the Web3 launch, evidence that consumer-facing blockchain works when the technology stays invisible.
Retail partner stores connected to OK Cashbag, each a real-world earn-and-burn touchpoint now backed by NFT rewards and self-sovereign asset ownership.
A loyalty program of this size cannot break.
OK Cashbag is the largest e-commerce loyalty network in Korea. The members are not asking for blockchain. They are asking for the program they already use. SK Planet's job was to put the program on better rails, quietly.
UPTN, the dedicated Avalanche L1 on AvaCloud, runs the new layer. A custom Gasless Relayer absorbs the transaction costs that would otherwise leak into the user experience. The members keep earning. The infrastructure underneath them changed.
What's new on top
- NFT-based event ticketing with Dreamus, real ownership, real resale rights, real audit trail.
- Brand collectibles issued by partner brands across the OK Cashbag footprint.
- A Web3 funnel for SK Square's broader ambitions, anchored in an existing 21M-member base.
What the 48-hour signup spike showed
When you don't ask consumers to learn Web3, they sign up faster. 100,000 net-new users in the first two days of the launch was the data point that turned the Web3 program from a pilot into a permanent rail.
