The corporate mentioned extra protocols, currencies, and blockchain networks will likely be added sooner or later. For now, assist is targeted on $USDC on Base, which supplies stability and predictable pricing.

Business observers see the transfer as one other signal that AI, fintech, and crypto have gotten extra intently related. As an alternative of counting on month-to-month plans or pay as you go credit, companies can now be priced per motion, per second, or per request.
