Circle has minted an additional $500 million in USDC on the Solana blockchain, bringing the total new USDC added to the network this week to $3.25 billion. This expansion comes as the cryptocurrency market experiences significant fluctuations, with Bitcoin dropping below $76,000 amid rising oil prices and geopolitical tensions. In other developments, Visa has integrated Polygon into its global stablecoin settlement program, which has reached a quarterly volume of $7 billion. This move highlights the growing adoption of blockchain technology in traditional financial systems, offering faster and more cost-effective transaction solutions.
