Stablecoin Rails Maturing

A card tied to a crypto wallet now moves about $600 million a month, up from $187 million a year earlier, which means people are no longer just buying tokens and holding them. They are tapping them at ordinary payment terminals and settling the bill through the same card networks stores already use. (coinspeaker.com) Visa handled about 97% of that March 2026 crypto-card volume, so this is not a parallel checkout universe with new hardware and new merchant contracts. It is mostly existing card rails with digital dollars plugged in at the funding layer. (coinspeaker.com) At the same time, Circle minted more than $10.5 billion of USD Coin on Solana in roughly a month, including about $3.25 billion between March 31 and April 6 alone. That is the on-chain version of loading more cash onto a faster highway because more traffic is showing up. (crypto.news) A stablecoin is a digital token designed to hold a fixed price, usually $1, so companies can move dollars on internet-style rails instead of waiting for bank cutoffs and batch files. Solana is one of the blockchains being used for that job because it is built for high transaction throughput and low fees. (crypto.news) Now the older payments companies want in. Fidelity National Information Services, better known as FIS, told American Banker it plans to offer stablecoins and tokenized assets as a service for banks that are too small to build that stack themselves. (americanbanker.com) That shift changes who the customer is. Instead of a crypto startup wiring together wallets, compliance tools, and settlement logic on its own, a regional bank could buy those functions from FIS the way it already buys core banking and payments software. (americanbanker.com) FIS is not starting from zero here. Circle said in 2025 that FIS would integrate Circle’s stablecoin functionality into products including Money Movement Hub, which is the company’s platform for sending funds across different payment networks. (circle.com) Banks have also been getting a clearer rulebook. On April 7, 2026, the Federal Deposit Insurance Corporation said it approved a proposal to implement requirements for permitted payment stablecoin issuers, including rules on reserves, redemption, capital, and risk management. (fdic.gov) That is why these three datapoints fit together. Consumers are spending through crypto-funded cards, issuers are loading billions of digital dollars onto faster chains, and bank vendors are packaging the plumbing into products a normal financial institution can actually buy. (coinspeaker.com) (crypto.news) (americanbanker.com) The result is less like a new coin replacing bank money and more like a new settlement layer slipping underneath familiar apps, cards, and bank dashboards. When the infrastructure companies start selling it as a standard feature, the experiment phase is usually ending. (americanbanker.com) (fdic.gov)
