Top 10 x402-related projects on Solana
The x402 narrative on Solana continues to expand as AI agents adopt autonomous payments. Several projects now support micropayments, agent hiring, and machine-led transactions. Market observers note rising activity as builders prepare infrastructure suited for long-term agent economies.
Growing x402 activity on Solana
Recent discussion around x402 projects on Solana gained traction after a post shared by Solana Hub. The update outlined ten projects linked to agent-based payments and automation. The post framed x402 as a technical layer enabling direct value exchange between autonomous systems.
Developers focus on use cases where AI agents operate independently. These agents can pay, trade, or hire other agents without human approval. This structure suits decentralized environments, where speed and cost control matter. As a result, x402 projects on Solana receive steady attention across trading and development circles.
The narrative also reflects higher facilitator volumes. Payment routing, enforcement, and settlement now occur within defined limits. This structure supports repeat usage rather than experimental testing. The market response reflects growing confidence in agent-to-agent payment design.
Leading facilitators and payment layers
PayAI Network appears as a leading facilitator within x402 projects on Solana. It supports autonomous agent hiring and direct payments. The platform operates as a decentralized marketplace, where agents transact using predefined payment rules. Observers note its consistent presence among high-volume performers.
Dexter AI also ranks among active facilitators. It combines AI trading tools with automated payment handling. The system executes trades while managing settlement through x402 flows. Market data often shows Dexter AI near daily gainers’ lists, reflecting strong user engagement.
X4Pay Core supports the base payment infrastructure. It focuses on seamless agent-to-agent transfers. Recent market movements placed the project among the top gainers. Together, these platforms form the backbone of x402 projects on Solana focused on execution and settlement.
Agent frameworks and collaboration tools
Daydreams Agents supports structured agent behavior with enforced x402 payments. The framework allows spending limits and cross-chain logic. This approach helps teams deploy agents with defined financial boundaries. Social data shows increasing mentions as builders test agent economies.
CollabraChain brings collaborative agent design into focus. After winning a hackathon, the project shifted development to Solana. It builds agent swarms that solve tasks together. Payments within these swarms rely on x402 integration for coordination and accountability.
Opus Universe also supports autonomous agents across blockchain and social layers. It emerged through hackathon participation. The project uses x402 for internal agent transactions. These frameworks expand the functional scope of x402 projects on Solana beyond payments alone.
Privacy, identity, and supporting infrastructure
RADR addresses privacy needs within x402 payments. It uses zero-knowledge proofs to protect transaction details. This approach supports private agent transfers without exposing identities. RADR maintains a steady presence among trending gainers.
Jatevo ID adds a verifiable identity layer for agents. It helps confirm agent authenticity during X402 payment flows. This function reduces friction where trust matters. ZAUTH also supports security testing for X402 endpoints through multimodal AI systems.
Relay AI operates as a communication and payment relay. It supports message routing alongside payments. Together, these tools complete the ecosystem around x402 projects on Solana, supporting privacy, identity, and secure agent interaction.
