**Major retail adoption milestone**: Hyungji, one of Korea's largest fashion retail groups, is implementing stablecoin payments across its network of over 2,000 locations throughout Asia. **Why Arbitrum**: The company selected Arbitrum as its settlement layer due to its fast transaction speeds, low costs, and reliability - essential requirements for serving millions of customers across a massive retail footprint. **Growing enterprise trend**: This deployment follows Arbitrum's track record in cross-border payments, where Rise Pay has already processed over $340M in USDC and USDT payouts on the network. The move signals increasing enterprise confidence in blockchain rails as a viable alternative to traditional payment networks for real-world commerce.

**DualMint has launched Seasoned Assets**, bringing real-world business tokenization to Arbitrum. The platform tokenizes community infrastructure including: - Laundromats - EV charging stations - Other local businesses **Chainlink integration** enables performance-based pricing, providing transparent data feeds for DualMint's tokenized machines. This marks another step in bringing tangible assets on-chain through Arbitrum's L2 infrastructure.

**PYUSD has emerged as the leading tokenized asset by market cap growth on Arbitrum.** The stablecoin's expansion follows PayPal and Paxos leveraging Arbitrum's infrastructure. **Key factors driving adoption:** - Deep shared liquidity pools - Fast settlement times - Low transaction costs This follows a pattern seen with Spiko's tokenized products (EUTBL and USTBL), which reached $273M+ in total value locked on the platform.
