Why is cross-border remittance so expensive and slow? A single international transfer takes traditional banks 3-5 days, and the fees eat up 6%. However, a company called Circle is redefining international payments using a different method.

What does Circle mainly do? It issues USDC - currently the second largest dollar stablecoin in the world. But it is far more than just "printing money."

**How is stability ensured?** Each USDC is backed by a real dollar at a 1:1 peg, with custodians including institutional giants like BlackRock, and audit data is publicly released every month. This trap system makes USDC an institutional-grade on-chain dollar.

**Why is it important?** Because USDC has been deployed on more than 15 blockchains, including Ethereum and Solana. Imagine this: the USDC you have on Ethereum can be used directly in the Solana ecosystem, without the need for complex cross-chain bridging, with liquidity flowing like a highway.

**What about the impact on the real world?** Enterprises and developers can access global payment capabilities with just a few lines of code—no intermediaries, no high fees. The cost of cross-border remittances has dropped from 6% to nearly zero, and transactions have been shortened from 3 days to seconds. When wages can be settled in real-time and international trade can be automatically cleared and settled, the traditional financial system seems outdated.

USDC is not just a trading tool; it is a testing ground for programmable currency—finding a compliant and stable new path between the lengthy processes of traditional banking and the volatility risks of cryptocurrencies.
