Stablecoins solve credit card fees for AI agents making thousands of tiny daily payments, per a16zcrypto and Phil Kwok.

According to Paolo Ardoino, Tether has integrated Bitcoin support via Spark into its Wallet Development Kit (WDK), enabling seamless Satoshi micropayments. This advancement allows individuals, machines, and AI agents to transact efficiently, showcasing the potential for Bitcoin in microtransactions.

According to Lex Sokolin, crypto’s edge is enabling AI-to-AI commerce via frictionless micropayments and computational-speed value transfer, not replacing human transactions.
