OnFinality Review (2026)

What is OnFinality?

OnFinality is a multi-chain node infrastructure provider with particularly strong support for the Polkadot/Substrate and Cosmos ecosystems, alongside EVM and other chains — filling a gap for developers in those ecosystems who are underserved by EVM-centric providers. It offers public and dedicated RPC endpoints, enhanced APIs, and node management tooling across a wide range of networks, with especially deep coverage of Substrate-based parachains and Cosmos app-chains that mainstream providers often neglect. This makes it a go-to for teams building in the Polkadot and Cosmos worlds who need reliable, specialized infrastructure. It offers free and paid tiers scaling by usage, plus dedicated nodes. The trade-offs: while multi-chain, its standout strength is the Substrate/Cosmos ecosystems, so for pure EVM work the big generalists may be more natural; its brand is smaller than Alchemy/Infura in the broader market; and advanced features sit on paid tiers. But for developers building in Polkadot, Kusama, Cosmos, or other Substrate/app-chain ecosystems — where finding quality, specialized node infrastructure is genuinely harder than on Ethereum — OnFinality is one of the leading providers, offering the ecosystem-specific depth and reliability those chains require, much as Helius does for Solana and NodeReal for BNB.
