Why Choose OnFinality for Avail Infrastructure?

Reliable blockchain infrastructure matters when your product depends on speed, uptime, and accurate onchain data.

High Performance Access

Support demanding Avail workloads with infrastructure designed for reliable throughput and stable performance.

Powerful RPC Analytics

Monitor RPC usage and performance with analytics that help teams manage and scale blockchain infrastructure more effectively.

99.99% Uptime

Run production applications on Avail with dependable infrastructure built for availability and consistency.

Connect via HTTPS or WebSocket

Use flexible connection options for applications that need both standard requests and real-time blockchain updates.

Decentralized Servers Hosted Globally

Access globally distributed infrastructure that improves resilience, reliability, and service reach.

Full Archive Access at No Extra Cost

Access historical Avail blockchain data for deeper querying, analytics, and advanced application needs.

Build faster with Avail RPC endpoints

Use OnFinality's Avail RPC APIs to connect wallets, dApps, dashboards, bots, and backend services without operating your own node from day one.

Public endpoint testing

Start with the Avail public RPC endpoint for lightweight checks, prototypes, and quick integration tests.

Authenticated API access

Move production traffic to authenticated endpoints when you need clearer limits, analytics, and operational visibility.

Standard RPC methods

Query Avail blocks, transactions, balances, events, and chain state through familiar HTTP and WebSocket workflows.

Operate Avail infrastructure with more control

Production teams need more than an endpoint URL. They need observability, predictable capacity, and a path from shared RPC access to isolated infrastructure.

Request visibility

Track usage patterns and response activity so your team can understand traffic growth before it becomes an incident.

Dedicated node path

Use dedicated Avail nodes when your workload needs isolated resources, custom operations, or stronger capacity planning.

Archive and historical data

Plan for archive access when analytics, audits, indexers, or advanced app features need older Avail state.

Choose the right Avail RPC setup

Different Avail products need different infrastructure. OnFinality gives teams a practical path from public RPC testing to production-grade API and node operations.
