OnFinality

OnFinality is a blockchain infrastructure platform that eliminates the need for development teams to operate their own nodes. Running blockchain nodes requires specialized DevOps knowledge, constant maintenance, storage that grows endlessly, and synchronization processes that can take days or weeks. OnFinality handles all of this, providing managed services across more than 130 blockchain networks so teams can focus on building applications rather than babysitting infrastructure. For teams building wallets, dApps, DeFi platforms, gaming applications, or analytics tools, OnFinality offers the reliable blockchain connectivity they need without the burden of node maintenance, synchronization headaches, or scaling concerns. The platform reports 99.99% uptime across its infrastructure and has served billions of API requests.

The RPC API service forms the foundation of the platform and serves as the primary way most developers interact with OnFinality. It provides both shared and dedicated blockchain endpoints with features that matter for production applications: request analytics to understand usage patterns, archive node access to query historical state, and Trace API support for debugging transactions. Network coverage spans the major ecosystems: EVM chains like Ethereum, Polygon, BNB Chain, Base, Arbitrum, and Optimism; Substrate-based networks including Polkadot; Cosmos chains; Solana; Bitcoin; and many others. Featured networks include Avalanche, TON, Sui, Aptos, and Monad. The free tier offers 400,000 daily response units, enough to build and test applications without immediate cost. Paid tiers scale up capacity with guaranteed performance.

Dedicated nodes provide an alternative for teams that need their own infrastructure rather than shared endpoints. Some applications require dedicated resources for performance isolation, compliance requirements, or simply want nodes running exclusively for their traffic. OnFinality offers one-click deployment for full nodes, validator nodes, and archive nodes with complete parameter control. The standout feature here is Lightning Restore technology, which syncs nodes in seconds rather than the days or weeks typically required for archive nodes. This dramatically reduces time to production when you need a new node, and disaster recovery or scaling doesn't require painful synchronization delays. Pay-as-you-go pricing means you're not locked into capacity commitments you don't need.

Indexing services address the challenge of making blockchain data queryable for application interfaces. Raw blockchain data isn't structured for the queries that applications need to make. You can't efficiently ask a blockchain node for all transactions involving a specific address over the past year, or aggregate trading volume by day. OnFinality hosts SubQuery and The Graph subgraphs, providing production-ready GraphQL APIs that make this kind of querying possible. This is essential for any dApp that needs to display historical data, show aggregate statistics, or provide responsive user experiences without waiting for on-chain queries. The platform handles millions of daily requests from active projects.

Staking and validator infrastructure lets teams participate in proof-of-stake networks without building validator operations from scratch. Running validators requires high availability, security hardening, key management, and monitoring that never sleeps. OnFinality offers white-label validator deployment across more than 90 networks, available as fully managed or self-service depending on how much control you want to retain. The non-custodial model means users keep control of their assets; OnFinality runs the infrastructure but doesn't hold keys. This is particularly valuable for institutions wanting to stake programmatically or offer staking services to their users.

For teams building new blockchain networks, particularly Substrate-based chains, OnFinality provides network prototyping tools with automated testing and deployment. Launching a blockchain network involves significant DevOps complexity, and OnFinality's self-serve capabilities support custom network launches without requiring a dedicated infrastructure team. The platform also offers AVA, an AI agent deployable to Discord and Telegram for community support. AVA integrates documentation and on-chain data to answer common questions automatically, reducing the support burden on core team members.

OnFinality distributes infrastructure globally across data centers in Singapore, Hong Kong, Japan, Ireland, Germany, and the United States, providing low-latency access regardless of where users are located. Support varies by plan, with enterprise customers receiving 24/7 access. The pricing model follows a consumption-based approach with transparent costs and no hidden fees. For teams evaluating infrastructure options, free consultations help map requirements to the appropriate service tier. The combination of multichain coverage, managed operations, and predictable pricing makes OnFinality suited to teams that want to ship blockchain applications faster without hiring specialized infrastructure engineers.
