The x402 protocol is an API auto-payment protocol tailored for AI Agents and the Machine Economy, designed to resolve payment challenges when automated programs invoke API services. By extending the HTTP 402 Payment Required status code and incorporating cryptographic payment mechanisms, it allows programs to automatically execute payments and settlements upon API requests. This establishes a more native internet payment infrastructure for machine-to-machine (M2M) service transactions.

Succinct’s Prover Network is a decentralized computing power market for zero knowledge proofs, or ZK proofs. It connects proof requesters with Prover nodes around the world. Developers initiate a proof request by submitting program code and input data. The network’s Auctioneer then assigns tasks based on cost, speed, and node reputation. Prover nodes execute the program on SP1 zkVM and generate the ZK proof, which is ultimately submitted on-chain for verification and settlement.

AI Model Routing is a technical mechanism that dynamically selects the most suitable model from a pool of AI models to handle incoming requests, also commonly referred to as an AI Model Router or LLM Router. By leveraging a model routing system, AI applications can automatically choose among different large language models (LLMs) based on factors like task complexity, cost, and response time, striking a balance between performance and cost.

An AI Agent API is a mechanism that enables AI Agents to invoke AI models or external services via an Application Programming Interface (API). Through APIs, AI Agents can access large language models, data services, and blockchain applications, thereby automating complex tasks.

Gate.AI is a one-stop intelligent large model routing platform designed for AI applications and AI agents. It enables developers to access major global models—including GPT, Claude, Gemini, and DeepSeek—through a unified API, while centrally managing model call costs, permissions, stability, and data security. The platform supports both OpenAI and Anthropic protocol compatibility, intelligent routing, automatic fallback, multimodal task capabilities, and enterprise-grade governance. Additionally, it integrates Gate Pay and the x402 protocol to deliver automatic payment and machine-to-machine (M2M) settlement for AI agents.

Gate.AI and OpenRouter are both AI model routing platforms (AI Model Router) that allow developers to call multiple large language models—such as GPT, Claude, Gemini, and DeepSeek—through a unified API. However, they differ significantly in product positioning and capability direction. OpenRouter is primarily an AI model aggregation access platform, focused on helping developers quickly invoke mainstream models and switch between them via a single interface. In contrast, Gate.AI extends further into enterprise-level AI infrastructure. Beyond model aggregation, it offers intelligent routing, automatic fallback, multimodal capabilities, enterprise governance, and AI Agent auto-payment features.

Succinct is a decentralized zero knowledge proof, or ZK proof, network built on Ethereum. It is designed to give developers programmable, low barrier infrastructure for proof generation. Through its core component, SP1 zkVM, developers can write verifiable programs directly in general purpose programming languages such as Rust, without manually designing complex ZK circuits. The Succinct Prover Network connects proof requests with global computing resources through an open Prover market, enabling proof generation, verification, and settlement.

Succinct and RISC Zero both provide zero knowledge proof, or ZK proof, infrastructure, but they are designed with different goals in mind. Succinct places greater emphasis on a decentralized proof market and a general purpose verification layer. Through its SP1 zkVM and Prover Network, it supports cross chain verification, Rollups, and verifiable AI computation. RISC Zero, by contrast, focuses more on a verifiable execution environment and developer experience, using RISC-V architecture to lower the barrier to building ZK applications. The two differ significantly in zkVM architecture, proof generation flow, economic mechanisms, ecosystem positioning, and suitable use cases.

Axelar’s General Message Passing (GMP) is a cross-chain messaging mechanism that enables smart contract calls and state synchronization between different blockchains. A typical GMP message goes through several steps, including initiation on the source chain, receipt by the Gateway, validator confirmation, Axelar Network consensus, and execution on the destination chain. The entire process is coordinated by Axelar’s decentralized validator network, enabling secure communication between blockchains.

Axelar Network is a cross-chain interoperability network built for the Web3 multichain ecosystem. Through decentralized validators and General Message Passing (GMP), it enables asset transfers, data communication, and smart contract calls between different blockchains. Unlike traditional cross-chain bridges, which mainly focus on moving assets across chains, Axelar places greater emphasis on “cross-chain messaging,” allowing developers to build composable cross-chain applications across multiple blockchains.

Axelar and Wormhole are both cross-chain interoperability protocols in the Web3 multichain ecosystem, but they use different technical architectures and security models. Axelar is built on an independent PoS validator network and General Message Passing (GMP), with a focus on unified cross-chain communication and interchain smart contract calls. Wormhole, by contrast, verifies cross-chain messages through the Guardian Network and focuses on cross-chain bridging and multichain messaging.

Axelar and LayerZero are both cross-chain interoperability protocols in the Web3 multichain ecosystem, but they differ clearly in technical architecture and security model. Axelar uses an independent PoS validator network and General Message Passing (GMP) mechanism to enable cross-chain communication through decentralized validators, while LayerZero is built on the Ultra Light Node (ULN) architecture and verifies cross-chain messages through an Oracle and a Relayer.

Interchain Token Service (ITS) is a cross-chain token infrastructure launched by Axelar. It is designed for native token deployment, management, and communication across different blockchains. ITS runs on Axelar’s General Message Passing (GMP) mechanism, allowing developers to connect multiple blockchain ecosystems through a single deployment.

Alaya AI is an open, composable Web3 AI data infrastructure network that seamlessly integrates distributed data communities, automated data processing for AI training, and blockchain-powered gamification incentives, delivering accessible, customizable, and auditable data pipelines for both individual and enterprise AI applications.

World Mobile Chain is a Layer 3 blockchain network built for communication infrastructure use cases. Built on Base and compatible with the EVM smart contract environment, it is mainly used to support decentralized mobile communication, eSIM services, digital identity verification, and on-chain network settlement. Through EarthNode, AirNode, and the WMTx incentive mechanism, it moves connection, authentication, and data billing processes from traditional communication networks onto the blockchain, creating a community-driven DePIN, or decentralized physical infrastructure network, ecosystem.
