Avail RPC Endpoints & Dedicated Nodes | OnFinality

Avail is a modular data layer designed to unify liquidity and scalability across blockchains. Its architecture includes a data-availability layer (availDA), a cross-ecosystem verification hub (availNexus), and a unified security layer (availFusion). By leveraging KZG polynomial commitments and data availability sampling (DAS), Avail provides trust-minimized scalability for rollups and app-chains, enabling unlimited blockspace and high-assurance security. Compatible with EVM, WASM, and custom execution environments, Avail supports real-time applications in DeFi, gaming, and large-scale dApps. Light-client verification allows users to securely verify blocks in seconds without running full nodes.

Public vs Private Avail RPC

Public endpoints are suitable for lightweight testing, but they often lack rate limits, observability, and reliability guarantees. OnFinality's authenticated endpoints provide clearer usage limits, request analytics, and a path to higher-capacity infrastructure. For production workloads, dedicated nodes offer dedicated resources and full control.
