Two major Wall Street players, Citibank and Western Union, are taking a leading role in the adoption of stablecoins, signaling a shift toward blockchain technology in traditional finance. Citi has partnered with Coinbase to offer on-chain payment solutions for corporate clients, leveraging USDC-based transactions for faster and more transparent transfers. Meanwhile, Western Union is developing its own stablecoin settlement system on Solana blockchain, aiming to enhance cross-border money transfers with reduced fees and accelerated processing times compared to conventional methods. These developments point to the growing influence of blockchain technology in financial infrastructure as major institutions embrace its potential for speed, cost-efficiency, and global reach.
