🦄 Cardano has joined Solana and XRP Ledger in the x402 developer stack for machine-to-machine payments. The standard turns the web’s “402 Payment Required” response into a programmable checkout, allowing apps and AI agents to pay for data or services inside an internet request without accounts or card details. Cardano’s new TypeScript tools can build payments in $ADA or Cardano-issued tokens, but the facilitator has only completed a pre-production transaction and is not yet proven on mainnet. $SOL and $XRP represent the other public networks already pursuing the same agent-payment model. The three assets are linked here through their native settlement ecosystems, not because x402 requires their tokens. The update expands competition to become a default rail for autonomous software commerce. #TrendingTopic #BTC #HotTrends #ETH #altcoins
