Hey folks, today I’m diving deep into the hardcore OpenLedger x402: the compatibility dilemma and breakthrough ideas for cross-ecosystem machine payments. It looks like the ultimate solution for AI machine payments, but when it comes to rolling it out across the broader web and heterogeneous AI systems, the compatibility hurdle is no walk in the park. From my trading experience, I’ll break down the issues neutrally and discuss potential improvements.
First, let’s talk core pain points: the initial goal of x402 was to let AI handle M2M micropayments autonomously, without human intervention. But in reality, its compatibility logic is stuck behind three major barriers: 'chain standards, token ecosystems, and system adaptation.' On the chain level, EVM chains rely on EIP-712 signatures, while Solana uses Ed25519, and the Move-based chains are entirely different. Each non-EVM chain requires separate coding, which drives up development costs. Tokens are even trickier; v1 was tightly bound to EIP-3009, but mainstream USDT doesn’t support it at all, and DAI uses EIP-2612, which directly knocked out 40% of the stablecoin market.
Now, looking at the adaptation with the broader web and heterogeneous AIs, traditional internet payments lack a blockchain concept, and each AI system has its own wallet logic. Some servers use single keys, while others operate independent wallets for each app. This leads to key fragmentation and asset dispersion, crashing both security and user experience. More critically, the authorization and billing models across different AI systems are worlds apart; the current standardized framework of x402 can’t cover all scenarios, and forcing adaptation will only lead to a mess of vulnerabilities.
That said, the team is making changes. v2 has adopted the CAIP-2 cross-chain standard, offering a unified interface that allows multi-chain integration without needing to change code.
However, to truly break through, they need to address three shortcomings:
First, create a universal signature adaptation layer that packages the signature logic of different chains, lowering the development threshold;
Second, open up token compatibility and stop fixating on EIP-3009, adapting to mainstream stablecoin standards;
Third, develop a modular wallet solution that supports user-controlled private keys, solving the key dispersion issue.
My personal take: in the short term, x402 will definitely focus on fortifying the EVM ecosystem to stabilize the foundation; mid-term, it will tackle mainstream non-EVM chains like Solana through modular adaptation; long-term success hinges on whether it can establish a 'chain-agnostic, token-compatible, system-adaptive' universal payment layer. The overall logic is solid, but the compatibility aspect needs to be refined step by step—it can’t be rushed.
