**Cosmos and x402** x402 is the latest proven development for the enablement of payment and AI infrastructure. With CosmWasm coming to Cosmos, the narrative for Cosmos to support DApps requires an equivalent, if not more, infrastructure and building blocks for developers. The first wave of Open Source projects in x402 were infrastructure projects, which allowed developers to leverage and build upon their applications. For Cosmos to be lucrative enough for developers who give a thought to build upon their DApps on the chain or launch a connected appchain, there needs to be a directed effort to support strong teams that build this infrastructure. **This post is to start a discussion around the same.** In the following, I cover 1. X402 overview 2. Data around x402 3. Different chains pushing towards x402 4. What Cosmos ecosystem lacks 5. How x402 can help $ATOM in the long term **1.** **X402** x402 is an open, internet-native payment protocol primarily developed by Coinbase, designed to enable autonomous payments using stablecoins and other crypto assets. It facilitates machine-to-machine (M2M) transactions, particularly for AI agents, allowing them to pay for services like API calls, data access, and infrastructure without traditional payment rails. **2. Market Size and Ecosystem Valuation** In just ~9 months since launch (May 2025), x402 has exploded into a multi-chain ecosystem with dozens of projects and tokens. - Total market capitalization of x402 ecosystem tokens exceeds $9.26 billion at the time of writing (1/02/26) - **Payment following x402 is expected to reach 30% of the Base Daily Transaction** - 24-hour trading volume across the ecosystem is approximately $767 million. - McKinsey predicts that agentic commerce is projected to generate $3-5 trillion in B2C revenue by 2030, with x402 positioned as a foundational rail for AI-crypto collaboration. - Active users: Up to 94,000 in recent peaks; total unique buyers: 550,000; sellers: 205,000. **Breakdown by Network** : - 35Mn$ + Volume processed - 127Mn+ Transactions **3. Different chains pushing towards x402:** Chains foresee a future where **API calls, AI model queries, IoT services, etc., all use crypto microtransactions under the hood**. 1. **Base (Coinbase’s L2):** As the birthplace of x402, Base dominates early usage. Coinbase’s own facilitator service on Base processed **~75 million x402 transactions (worth $24M)** in the protocol’s first 7 months. 2. **Solana:** Solana’s ecosystem and foundation are **actively promoting x402**. For example, a dedicated Solana x402 Hackathon in late 2025 drew builders to create x402-based tools, agents, and dApps. Solana even briefly _surpassed Base_ in daily x402 transaction count on some days. 3. **Celo:** The mobile-oriented Celo network recently **integrated the x402 agent payment framework at a protocol level**. This allowed Celo-based dApps to accept HTTP-402 microtransactions in any token. They’ve even discussed **tiered fee models for agent payments** (capturing tiny fees from each bot transaction). Celo’s proactive support shows an attempt to carve out a niche (mobile AI agents) in the x402 landscape. 4. **Other Chains:** Many EVM chains are x402-compatible by default. For example, Polygon, BNB Chain, and even Ethereum L1 have seen small but growing x402 usage. 5. On BNB Chain, an independent project (AEON) launched an x402 facilitator in Oct 2025 to enable agent payments with Binance Smart Chain and even generate on-chain **receipts with agent IDs** for auditability. 6. Cloudflare is backing the x402 Foundation and plans to support it in its network services, and **Google** is integrating x402 with its Agent Payment Protocol (AP2) standard for AI services. **Emerging Use Cases** : API monetization (e.g., trading data from Nansen), infrastructure (e.g., Nous Research’s models), and e-commerce integrations. **Future Outlook** : Gradual adoption with hybrid permissioned/permissionless systems; potential for x402 to reshape SaaS and payments invisibly. **4. Tools and Infrastructure in x402 Absent or Underdeveloped in Cosmos** - **Facilitators (Payment Intermediaries)**: A developer building an API on Cosmos today cannot easily plug into an equivalent of Coinbase x402. They would have to run custom infrastructure. (Even **Sei** , a Cosmos-based chain, had to fork Coinbase’s x402 code to experiment with it.) - **Multi-Chain and Cross-Chain Tooling** : x402 supports EVM (via EIP-2612), Solana (SPL tokens), and others with SDKs for TypeScript, middleware, and extensions (e.g., Chrome plugins for testing). V2 upgrades include smart routing, modular SDKs, and fiat ramps. - **Agent-Specific Infrastructure** : x402 integrates with standards like ERC-8004 for agent identity/verifiability, enabling trustless economies (e.g., bidding, advertising). Tools like x402 Starter Kits (with Solana support, Dockerized for TEEs) allow quick API deployment. Projects like **Zauth** have sprung up to continuously **test x402 endpoints and filter out failing services** (addressing the fact that many API endpoints can be down or return errors ~50% of the time, which would confuse agents). - **Analytics and Monitoring Tools** : x402 has dedicated browsers like x402scan for tracking payments and servers, plus dashboards (e.g., onbase.dev tracking 121M tx and $35M volume in 3 months). - **Economic and Compliance Features** : x402 includes multi-token support, zero-centralization extensions, and compliance-ready demos (e.g., age-verified tx). **5. Why Cosmos Needs x402 (Benefits to $ATOM and the Ecosystem)** Integrating x402 capabilities into Cosmos Hub and the Interchain stack could yield significant strategic and economic benefits: - **Attracting Developers and Innovation:** Cosmos has always marketed itself as the “Internet of Blockchains,” appealing to builders of new app-chains. To maintain that appeal, Cosmos must offer relevant capabilities. Right now, AI agents and micropayments are a hotbed of innovation with _over $26M in x402 payments processed in Nov 2025 alone, up 10x from the month before_. By supporting x402, Cosmos could draw in teams working on **AI-driven applications, data marketplaces, IoT services, and more**. These developers could choose to launch their own Cosmos consumer chains or deploy contracts on Cosmos Hub, knowing they can easily monetize via 402 payments. - **New Use Cases on Cosmos:** With x402 infrastructure, we can expect **a wave of novel applications** leveraging Cosmos’s interoperability: - **Capturing Transaction Volume (Fee Revenue):** More transactions mean more fees burned or distributed to stakers. If Cosmos can capture even a slice of the x402 transaction flow, it could translate to meaningful on-chain activity. For perspective, x402 saw up to **2–3 million transactions _per day_** at its Q4 peak (across Base and others). These are often small value ($0.01–$0.10), but they add up in count. Cosmos Hub currently averages only on the order of tens of thousands of daily transactions (mostly governance, staking, IBC). - **Strengthening ATOM’s Value Proposition:** **ATOM’s price ultimately reflects confidence in the Cosmos Hub’s utility and economic throughput.** Right now, narratives around ATOM have been focused on Interchain Security and liquid staking but perhaps not enough to spark major new interest. The **agentic payments narrative could provide a fresh catalyst** for ATOM. - **Competitive Differentiation:** Ethereum has the core standards but is expensive per txn, Base is heavily Coinbase-run and Solana has a different programming model. Cosmos could position itself as the **neutral, interoperable settlement layer** for agent payments. - **Synergy with Interchain Stack:** **Interchain Accounts and Interchain Queries** could be used by agents to move funds or fetch data across multiple zones in one payment flow. As of now, the only x402 module that exists for Cosmos is by Vitwit, but it’s not enough. We need to do a **hard push for rapid and time bound development** with fast deployment of funds to support the teams. ---

Overall a good idea but would need for that first a dedicated stablecoin and all crypto/fiat rails payment integration A lot to be done before by the ICL but it seems it’s not at all developped unfortunately (and it takes quite a lot of time/ressource) ---

There wasn’t any infra when $USDC started The infra is build on top of the liquidity, not the opposite ---
