We are proud to announce support for Base, a secure, low-cost, developer-friendly, and Ethereum Virtual Machine (EVM) compatible suite of Ethereum scaling solutions.

OnFinality will provide easy to use, reliable and scalable API endpoints for builders to deploy and run their dApps on Base quickly and easily!

“With the rapid rise of Base, OnFinality is excited to be able to provide this to existing partners and new web3 builders as soon as possible.”

What is Base?

Base is a new Ethereum Layer 2 (L2) chain that offers a safe, low-cost, developer-friendly way to build on-chain. The Base blockchain is build on the OP Stack (Optimism) and is a project incubated by Coinbase, yet will not have a network token.

  • Secured by Ethereum: Base leverages the underlying security of Ethereum, along with Coinbase’s best practices, to enable developers to confidently onramp into Base from Coinbase, Ethereum L1, and other interoperable chains.
  • Empowered by Coinbase: Base makes it easy to build decentralized apps with access to Coinbase’s products, users, and tools. Seamless Coinbase product integrations, easy fiat onramps, and powerful acquisition tools enable developers to serve the 110m verified users and $80B+ assets in the Coinbase ecosystem.
  • Big features, small fees: Base offers full EVM compatibility at a fraction of the cost and is committed to pushing forward the developer platform. Set up gasless transactions for your dapps with easy developer APIs for account abstraction, and securely build multichain applications with easy-to-use bridges.
  • Open source: Base aims to be decentralized, permissionless, and open to anyone with the vision of creating a standard, modular, rollup agnostic Superchain powered by Optimism.

By connecting to Base with OnFinality’s API endpoints, builders will be able to:

  • Access the Base network quickly in minutes without having to set up or manage infrastructure
  • Enjoy global performance, automated scalability and high availability of up to 99.99% uptime per year!
  • Gain valuable API Insights for you to spot issues on your apps and quickly implement rectifications for a bug-free user experience
