UnichainOnFinality is a blockchain infrastructure platform that helps Web3 builders save time by delivering scalable API endpoints for major networks and enabling them to test, deploy, scale and monitor their own blockchain nodes in minutes.
It provides on-demand dedicated nodes, API and network prototyping services, and a globally distributed Enhanced API for reliable, scalable endpoints.
With Lightning Restore technology and Substrate Network Prototyping, users can rapidly deploy, test and scale their projects using flexible, self-serve DevOps.
What a testnet gives you that local development cannot, and how to exercise code against real network conditions first.
Full nodes forget old state; archive nodes keep all of it. Which queries need which, and why the second costs so much more.
Rate limits explained from the provider side, with the batching and backoff changes that actually stop the errors.
