**AltLayer x402 Suite** introduces a new payment model for agentic systems, embedding payments directly into API calls with onchain settlement verification. **Key components:** - **Gateway** - payments embedded in API calls - **Facilitator** - verified onchain settlement - **x402 for Rumour** - pay-per-signal intelligence The system operates on a **per-request payment model**, where each interaction is paid, settled, and verified at execution time. This removes trust assumptions by linking payment, execution, and outcome in a fully auditable trail. The architecture is designed for systems where value moves with each request, creating execution-level economics rather than traditional pricing models.

**8004scan introduces capability-based filtering** to help users navigate thousands of ERC-8004 agents across the ecosystem. **Key features:** - Filter agents by specific skills and capabilities - Quick discovery of agents built for exact tasks - Streamlined search from registry to deployment The tool addresses a growing need as the ERC-8004 ecosystem expands to over 75,000 registered agents across 21 integrated chains, making manual discovery increasingly impractical.

**Rollups are becoming the standard approach for scaling applications**, and AltLayer's Rollup-as-a-Service (RaaS) platform streamlines the deployment process. The platform offers: - **Custom chain design** - Select stack components that match your specific architecture - **Built-in infrastructure** - Deploy with operational support already configured - **Fast deployment** - Launch quickly with unlimited scaling potential Developers can focus on building their applications rather than managing infrastructure. The RaaS dashboard allows teams to combine execution, data availability, settlement, sequencer, and interoperability components to fit their needs. Once configured, rollups can be deployed in just a few clicks, even without coding experience. This no-code approach removes technical barriers while maintaining flexibility for custom requirements.

**AltLayer wrapped up a busy February** with significant developments across its ecosystem: - **Agent Infrastructure Expansion**: Enhanced agentic infrastructure capabilities - **8004_scan Improvements**: Major upgrades to the scanning tool - **New Builder Tooling**: Fresh developer tools released by @yq_acc - **Strategic Partnerships**: Multiple new collaborations announced The protocol continues building momentum with more updates promised for the coming months.

A new open-source security platform called **SolidityGuard** has launched to help developers identify smart contract vulnerabilities before deployment. **Key Features:** - Free and open-source security analysis tool - Catalogs 104 real-world vulnerability patterns - Integrates 8 security engines including static analysis, fuzzing, symbolic execution, fork testing, and formal verification - Accessible to all builders without cost barriers The platform addresses the reality that most smart contract exploits are predictable rather than unexpected events. By providing systematic detection capabilities, SolidityGuard aims to catch vulnerabilities before they become security incidents. Developers can access the tool at [solidityguard.org](https://solidityguard.org/) and view the source code on [GitHub](https://github.com/alt-research/SolidityGuard/releases).
