The stablecoin ecosystem on Arbitrum has already formed a substantial infrastructure. The total on-chain stablecoin market capitalization has surpassed $7.8 billion, and the total transaction transfer volume over the past 30 days has reached $74 billion, with the number of token holder addresses exceeding 7.75 million. What do these data points reflect? Arbitrum is gradually evolving into a mature stablecoin settlement layer. This liquidity aggregation effect has built a solid infrastructure foundation for payment service providers and financial institutions, and also means that more and more payment applications have the opportunity to be implemented on this chain.
