ETH and SOL back new payments protocol

TLDR

Ethereum (ETH) and Solana (SOL) are jointly backing a new agent payments protocol that aims to standardize how automated, onchain payments work across multiple chains.

1. OKX has launched an agent payments protocol co-signed by the Ethereum Foundation and Solana, alongside a coalition including AWS, Paxos, Uniswap, and Sui.
2. The standard targets agent use cases, where software and AI agents make continuous onchain payments, potentially positioning ETH and SOL as key settlement layers for this flow.
3. The real test will be adoption by wallets, stablecoin issuers, and merchants, and how this protocol competes or interoperates with other emerging payment standards.

Deep Dive

1. Who Is Backing What

According to recent coverage, OKX has launched an agent payments protocol that has formal backing from both the Ethereum Foundation and Solana, plus partners such as AWS, Paxos, Uniswap, and Sui here.

The protocol is framed as an open standard for how onchain agents (automated services, bots, or AI systems) initiate and settle payments, similar in spirit to how TCP/IP standardized internet data transport.

The same report notes that agent-style transactions are already meaningful, citing over 50 million such transactions on Coinbase in Q1 2026, which is why major infrastructure players are trying to lock in standards early.

2. Why This Matters For ETH And SOL

By co-signing the standard, Ethereum and Solana are signaling that they want agent and AI-driven payments to be native, multi-chain, and interoperable rather than siloed to a single ecosystem.

If the protocol gains traction, a growing share of automated payment flows, likely denominated in stablecoins, could route through ETH mainnet, its L2s, and the Solana network, reinforcing them as base layers for programmable money.

This move also fits a broader trend: for example, MoonPays Open Wallet Standard for AI agents is likewise backed by the Ethereum Foundation and Solana Foundation, alongside firms like PayPal and Circle here, and crypto payment rails already handle trillions in annual stablecoin volume relative to traditional card networks here.

3. What To Watch Next

1. Integrations: Which wallets, L2s, payment processors, and stablecoin issuers actually implement the OKX agent payments spec, and whether support is symmetrical on Ethereum and Solana.
2. Flow patterns: Whether micro, high-frequency agent payments gravitate to low-fee environments like Solana or specific Ethereum L2s, while higher-value or institutional flows favor Ethereums security.
3. Standard wars: How this protocol coexists with other efforts such as MoonPays Open Wallet Standard, Western Unions Solana-based USDPT stablecoin network, and card-based agent rails, and whether one becomes the default API for agentic payments.

Conclusion

Ethereum and Solana backing a shared agent payments protocol is a strategic attempt to shape how AI and automated systems move money onchain.

If the standard becomes widely adopted, it would reinforce both chains as core settlement layers for programmable payments, but the real signal will be concrete integrations and stable, growing transaction volume routed through the new rails.
