Where are the asset opportunities on BASE, BSC, and Solana during x402 carnival?

Written by: David, Deep Tide TechFlow

Now, when you open the on-chain data of x402, you will see an interesting phenomenon: all Base blue labels.

In the past 24 hours, tens of thousands of transactions have all occurred on Base. There is no Ethereum mainnet, nor any sign of BSC or Solana.

This is very normal, after all, x402 is a protocol proposed by Coinbase, so it naturally needs to run on its own Base chain first. Previously, $PING surged, and various similar imitation trading activities also emerged. With this trump card, Base's daily active users and attention are skyrocketing.

However, x402, can it only be played on Base?

From a technical perspective, the core of x402 is the HTTP 402 status code combined with on-chain stablecoin payments. In simple terms, any chain that can run smart contracts, has affordable gas fees, and stablecoin liquidity can implement it.

(If you are not familiar with the technology of x402 and its associated protocols, please refer to: x402 is gradually becoming competitive, uncovering new asset opportunities in ERC-8004.)

The reason x402 is only on Base is not due to technical limitations, but rather Coinbase's home-field advantage. However, technology is open source, and protocols can be forked, which also means that other chains still have opportunities.

Currently, there is an interesting situation in the x402 narrative:

There are two chains with core technological standards in hand (Ethereum and Base), holding ERC-8004 and x402 respectively, but lacking speculative traffic and liquidity; while the two chains with the most traffic (BNB Chain and Solana) lack relevant technical orthodoxy and projects.

In the uneven development mentioned above, absence is sometimes not a bad thing; rather, it provides space for new projects to develop.

We reviewed the current market on BNB Chain and Solana related x402 projects to help everyone better identify assets in this round of narrative.

BNB Chain Ecosystem Project Overview

The actions of BNB Chain in Perp DEX and meme launches have been well noted, and it has produced assets like $Aster and $BinanceLife; now x402 has arrived, and the entire chain ecosystem seems too calm.

However, from infrastructure to applications, some projects are quietly brewing and building.

b402, Payment Protocol Standard (No Token Available)

Just look at the on-chain data of x402 now, and you'll see that almost all the Facilitators are on Base and Solana.

If you don't know what a Facilitator is, a simple explanation is:

The payment processing center in the x402 ecosystem is responsible for verifying AI's payment requests and handling on-chain settlements. Without it, the Agent's payment requests cannot be transformed into actual on-chain transactions.

What does this mean? If an AI Agent on BSC wants to charge a fee, it either needs to cross-chain to Base or build a payment system from scratch.

Among all the infrastructure that BSC may need, the payment layer is the most critical. Without payment, there is no economic activity; without economic activity, an Agent is just a toy.

This is what b402 is doing, the first AI Agent payment standard on the BNB Chain.

In simple terms, b402 has fully brought the capabilities of x402 to BSC, but with a different technical approach.

Because BSC tokens (such as USDT) do not support EIP-3009, and 3009 is a standard that allows tokens to support “delegated Gas payment”. With it, users can sign an authorization, and then someone else (like a service provider) can help you pay the Gas fee to complete the transfer.

Why can't BSC's USDT function without this feature?

Imagine an AI Agent needing to pay for API calls. On Base, it just signs an authorization, and the facilitator x402 will help it pay the Gas. But on BSC, USDT does not have EIP-3009, so the Agent must hold BNB to pay for the Gas fees.

Therefore, B402 achieves the above functions through a series of mechanisms, allowing users to pay by signing without needing to hold BNB to pay Gas.

By examining the documentation of B402 closely, we can find that it mainly addresses three issues:

Allow all BEP-20 tokens on BSC to be used for Agent payments, not just a specific token;

By integrating ERC-8004, Agent authentication and payment can be completed within the same system;

Millisecond-level processing speed is crucial for high-frequency agent interactions.

More ambitiously, B402 is not content with just being a protocol. You can understand it by looking at its architecture diagram:

The bottom layer is the protocol (smart contracts), the middle layer is the service layer (Facilitator and b402scan), and the top layer is the developer tools (SDK).

Among them, b402scan is particularly noteworthy. It is not just a simple blockchain explorer like x402scan, but rather an AI service “seller launchpad,” more akin to a crypto version of Alibaba and Shopify.

To put it simply, b402scan aims to solve the problem of how to quickly launch AI services and get them noticed by the market. Suppose you have a weather data API and want to charge AI Agents for its use.

In the traditional model, you need to build your own payment system, handle on-chain transactions, and find ways to get people to discover you. But with b402scan, you only need a few steps: upload your API information, set the price, and deploy on-chain.

The remaining payment verification, on-chain settlement, and curation, etc., are all handled by b402.

This is somewhat like the early days of Taobao. Before Taobao, individuals wanting to open an online store had to handle payment, logistics, and promotion themselves. Taobao provided a one-stop platform that allowed anyone to easily start.

b402scan is such an existence for AI service providers on the BNB Chain. Buyers who need to purchase services can directly explore what services are available on b402scan.

Unibase, AI Memory Layer +x402 Facilitator ($UB)

What Unibase does is actually different from B402. B402 is a payment protocol redesigned for BSC (because BSC tokens do not support EIP-3009), while Unibase directly moves Coinbase's x402 protocol to BSC.

According to the information on its official website x402.unibase.com, Unibase is the “first x402 Facilitator on BSC,” supporting the EIP-3009 standard and providing standard x402 interfaces such as verify and settle.

It did not forcibly make BSC's USDT support x402, but instead created XUSD, a wrapped stablecoin specifically designed for x402 that supports EIP-3009. Users can wrap USDC into XUSD at a 1:1 ratio and exchange it back after use.

Any x402 application running on Base theoretically only needs to change the Facilitator address and token address (USDC→XUSD) on Unibase, and the code logic does not need to be changed at all, to run on BSC.

In addition to Facilitator, Unibase has also developed a BitAgent platform that allows developers to quickly issue AI Agents, in conjunction with Unibase Memory (memory storage layer), forming a complete ecosystem of “payment + issuance + memory.” It's somewhat like a mini version of the Base AI ecosystem replicated on BSC.

Pieverse, the Facilitator that solves compliance issues ($PIEVERSE, Pre-TGE event is currently ongoing)

For traditional enterprises using AI Agents, the biggest headache is probably not the technology, but financial compliance. Every payment requires an invoice, needs audit evidence, and must comply with local tax laws.

The original x402 protocol did not take these into account, but Pieverse's x402b did.

Pieverse's Facilitator will automatically generate “jurisdiction-compliant receipts” during each payment settlement and permanently store them on BNB Greenfield (the decentralized storage layer of BSC).

This means that businesses can retrieve the full documentation of any AI Agent transaction at any time to meet auditing requirements.

From an investment perspective, if you believe that the enterprise-level AI Agent market will explode, Pieverse might be an interesting target. Previously, Pieverse was also a graduate of Binance's MVB Season 9 project incubation, securing $7M in strategic financing led by Animoca Brands.

Currently, Pieverse is also conducting Pre-TGE activities in the Binance wallet. Participating in this activity requires spending 15 points, and in addition, various tasks such as following, retweeting, and using services must be completed to obtain airdrop opportunities.

AEON, which itself does cryptocurrency payments and integrates x402 (no tokens available)

AEON is a larger AI payment framework, and x402 is just one of the protocols it integrates.

What AEON is truly doing is connecting cryptocurrency with real-world payments. According to their data, AEON has already connected with over 20 million merchants, mainly distributed in emerging markets such as Southeast Asia, Latin America, and Africa.

On October 27, AEON launched x402 Facilitator on the BNB Chain, enabling AI Agents to utilize AEON's payment network.

The advantage of AEON is that it is the winner of the 10th season of the BNB Chain MVB, standing out from over 500 projects. More importantly, it has discussed cooperation with Visa and Mastercard, planning to enter the North American and European markets by 2025.

From an investment perspective, AEON is not a pure x402 concept, but rather a composite of “AI + payment + real-world implementation.”

TermiX, integrated with x402, allows every Agent to charge (no tokens available)

TermiX plays a unique role in the x402 ecosystem on BSC: it is a platform for creating Agents, but the key is that these Agents can all charge through x402.

In simple terms, TermiX provides a low-code environment that allows you to create AI Agents by dragging and dropping. But more importantly, these Agents come with “payment functionality” built-in: by integrating the x402 protocol, each Agent can charge autonomously.

For example, if you create an “On-chain Data Analysis Agent,” when other users or Agents want to use its services, it will automatically trigger an x402 payment. The TermiX SDK has already encapsulated the x402 payment process, so the creator does not need to understand the technical details of payment; they just need to set the price.

The tweet on October 26 showcased their demo: tokens can be created through simple conversations, and all on-chain operations involved can be automatically paid through x402. This means that Agents on TermiX not only can charge fees but also can actively pay to purchase other services.

From the perspective of the BSC x402 ecosystem, if B402 and Unibase are the infrastructure, then TermiX is the application layer, which allows more Agents to enter the market, and these Agents are all potential users of x402.

Zara AI, AI Development Factory Platform (No tokens available)

Zara AI is an autonomous AI development factory and agency platform that allows users to quickly build, test, deploy, and monetize AI-driven applications and agents in just a few minutes.

According to public information, Zara integrates the x402 protocol, enabling AI agents to make USDC instant payments through a single API request.

Agents can autonomously discover services at runtime, negotiate prices, and make payments through x402, deploying dApps with built-in payment functionality on Solana, Base, and BNB Chain.

Its partner Vistara Labs has also open-sourced b402 (gasless payments on BNB Chain, mentioned earlier), enabling cross-chain proxy trading.

Overview of Solana Ecosystem Projects

First of all, there is no need to elaborate on the previously risen PayAI Network. As a core facilitator of the Solana ecosystem x402, it currently also acts as a Facilitator, handling verification and settlement.

In addition to memes, some projects with stronger fundamentals are being driven by the official Solana hackathon.

Solana launched the official x402 Hackathon on October 28, in collaboration with Trends.fun, with a total prize pool of $50K, covering 5 tracks:

Best trustless proxy, best x402 API integration, best MCP server, best x402 development tools, best x402 proxy application. The event will last until November 11, and the winners will be announced on November 17.

From the themes set by these competitions, we can also see some popular or lacking directions around x402 within the Solana ecosystem:

Prior to the payment, AI verification/reputation assessment: How do I know who this AI is before we make a payment? What is its reputation?

In the middle, intermediary bridge: Similar to Payai, when AI pays to the API, the crypto for payment needs to be relayed to the chain by an intermediary.

The main character in doing things, AI: Develop some real AI applications that can use x402, rather than just pure memes like $PING .

As soon as the announcement of this hackathon was released, the comment section was already flooded with various projects actively responding from the Solana ecosystem.

Daydreams, a community-driven x402 ecosystem builder ($DREAMS)

On the Facilitator leaderboard of x402, Daydreams is currently in third place, having processed over 50,000 transactions.

On October 30, Daydreams announced an interesting gameplay: releasing 20 bounty tasks of $1,000 each, for a total of $20,000. Each bounty funds the development of a small API service, which are charged through x402. They call it “Microbusinesses that can be built in a day.”

This model is very clever. Instead of developing all services by itself, it is better to let the community build them. Each developer who receives a bounty will create a paid API x402, which will attract more AI Agents to use and pay for. Daydreams provides three core tools to support this ecosystem:

Daydreams Framework: A modular Agent building framework that supports TypeScript, allowing for quick assembly of AI Agents.

Daydreams Router: Allows Agents to access various AI models such as GPT, Claude, Groq, etc., with instant settlement of USDC through x402.

LUCID platform (coming soon): Combining x402 and ERC-8004, allowing Agents to have identity, payment capability, and autonomous operation.

Daydreams not only supports Solana but also covers Base and Starknet, making it a true multi-chain Facilitator.

Switchboard, supports the x402 oracle ($SWTCH)

Switchboard is a decentralized oracle protocol in the Solana ecosystem, with core products including Surge (real-time price streams with sub-100ms latency), Oracle Quotes (non-chain integration), and verifiable random number services, protecting over $5 billion in assets for more than 50 protocols.

On October 23, Switchboard achieved x402 compatibility through the Corbits SDK, becoming the current “only x402 compatible oracle.”

This integration allows AI agents to pay for data query fees on demand using SPL tokens (such as USDC), with each query costing less than $0.001.

Frego - Web3 AI Security Platform ($FREGO)

Frego's main business is to provide a unified control panel for building, deploying, and managing AI agents in blockchain environments.

Core features include FregOS (Web3 AI Agent Operating System), real-time security barriers, complete observability, and automated compliance auditing.

FregOS has built-in native x402 support, allowing agents to seamlessly handle micropayments (such as paying for cross-chain data or services using SPL tokens on Solana).

Features include trading simulations with risk assessment, execution of strategies to block unsafe payments, and one-click API integration for intermediation business.

Frego's guardrail function ensures that x402 transactions comply with security protocols, preventing unauthorized fund losses and other exploit vulnerabilities.

Foundry, AI native proxy infrastructure ($FDRY)

Foundry builds dedicated AI agents for small teams and AI-native startups, focusing on specific domain tasks rather than general-purpose tools.

The product line includes generating professional video marketing content, programming AI agents, and a feature called Unbrowse, which allows AI agents to browse the internet faster.

However, the market value of $FDRY is relatively small, and the price fluctuates wildly.

The recent catalyst is that Foundry has integrated x402 for autonomous network proxy payments, enabling real-time micropayments at the network layer through Unbrowse.

On October 30, it announced its participation in the x402 Solana hackathon, focusing on real-time AI settlement, and was also included in the x402 ecosystem token list by CoinGecko.

NICO, AI companion on the Solana chain ($NICO)

Niconico.ai is an AI-driven co-pilot tool designed specifically for the Solana blockchain, aimed at simplifying user interactions with on-chain activities.

Integrate DeepSeek (AI processing), Helius (Solana blockchain data), and Privy (wallet integration) APIs, allowing users to get started with just an email. Core features include trend analysis (identifying popular Solana tokens), token insights, on-chain execution, price forecasting, and upcoming sniping tools.

Similarly, the current market value of the NICO token is very low and needs to be approached with caution.

The project team is exploring the integration of the x402 protocol to enable USDC micropayments in the application. On October 28, their tweet confirmed that “$NICO is launching on x402, allowing users to make USDC payments via 402 HTTP requests.”

Opus Genesis, a social-driven autonomous AI agent ($OPUS)

Opus Genesis is a project on Solana that focuses on autonomous AI agents, integrating the chain with social networks to cultivate AI capable of autonomous operations.

Opus has previously integrated x402, and the AI persona can use x402 to conduct inter-agent transactions, data queries, and some small business operations.

Specific applications include pay-per-use API calls ($0.001-$0.01/request) and M2M (machine-to-machine) payments for trend analysis or community governance.

The project won third place in the Coinbase x402 hackathon (“at that time the project was named x402 OPUS Infinite Marketplace”) and is currently participating in the ongoing Solana x402 hackathon.

Due to space limitations, not all x402 ecosystem projects on Solana are fully listed here.

However, the above projects showcase the diversity of the Solana x402 ecosystem, ranging from oracle infrastructure to AI security, development frameworks, and autonomous agent platforms. We can look forward to the award-winning projects that will emerge after the conclusion of the upcoming hackathon.
