Okx Launches Agent Payments Protocol With ETH And Solana Backing

OKX has unveiled the Agent Payments Protocol (APP), an open standard enabling AI agents to manage full commerce lifecycles onchain — from escrow and negotiation to dispute resolution — with backing from AWS, Alibaba Cloud, the Ethereum Foundation, Solana, and more.

@okx has launched the Agent Payments Protocol (APP), an open standard designed to let AI agents handle the full lifecycle of commercial transactions — not just one-off payments — entirely onchain.

The move marks a significant step in OKX's evolution from trading venue to infrastructure provider, and puts it in direct competition with @coinbase's x402 protocol and @Stripe's Machine Payments Protocol in the race to define how AI agents move money.

Beyond Simple Transfers

Most existing agentic payment tools are built to execute a single transaction on a single request. OKX argues the real bottleneck has shifted from intelligence to commerce — covering quoting, negotiating, escrowing funds, metering usage, settling, and resolving disputes — and that existing solutions were designed to manage a single payment, not a relationship.

According to OKX, APP enables AI systems to handle not only payments but also quoting, negotiating, escrow, usage tracking, settlement, and dispute handling within a single framework. At the implementation layer, APP operates a Payment SDK that enables developers to roll out support for one-time payments, batch payments, and pay-as-you-go payments using OKX's X Layer blockchain, offering zero or low gas transactions.

The protocol also integrates the self-custodial, TEE-secured OKX Agentic Wallet, which supports over 20 chains. In addition, APP connects agents for communication over HTTP and XMTP protocols and messaging platforms like Telegram.

A Broad Coalition of Backers

AWS, Alibaba Cloud, the Ethereum Foundation, @solana, @Uniswap, @PaxosGlobal, and @MoonPay signed on from day one, among others. At the blockchain level, OKX said it has worked with ecosystems including @base, the @ethereumfndn, @solana, @SuiNetwork, @aptos, and Optimism to support interoperability.

OKX Global CEO Star Xu said billions of AI agents will soon operate globally and will prefer cryptocurrency wallets over traditional bank accounts. Xu described the protocol as "the key step that brings the Agent economy to real-world implementation."

APP is the third major agentic payments standard to emerge in recent months. This follows similar offerings like x402, the open protocol incubated by @coinbase, and the Machine Payments Protocol proposed by @Stripe. OKX positions APP not as a competitor to these efforts but as a layer built on top of them — one that adopts compatible wire formats where they already exist, and extends the vocabulary into territory they deliberately left out of scope.

The broader context is a rapidly crowding field. The launch arrives as competition to define standards for AI-driven commerce intensifies: @coinbase's x402 has expanded into an agent-facing marketplace, Stripe-backed infrastructure is advancing through the Tempo blockchain and its own Machine Payments Protocol, and Visa has opened card payment access to AI systems through developer tooling.
