How To Build On The Ethereum Blockchain With OnFinality

OnFinality, a multi-chain infrastructure provider, supporting over 60 chains on Avalanche, Ethereum, Cosmos and Polkadot, delivers scalable API endpoints for web3 developers to build on the Ethereum blockchain.

OnFinality is a blockchain infrastructure platform that saves web3 builders time and makes their lives easier. We deliver easy-to-use, reliable and scalable API endpoints for the biggest blockchain networks and empower developers to automatically test, deploy, scale and monitor their own blockchain nodes in minutes.

We also support Layer-1 ecosystems such as Cosmos, Avalanche and Polkadot, and are continuously expanding these mission-critical services to other ecosystems to help developers build the decentralised future, faster!

In this OnFinality Layer-1 Introduction series, we gather resources that may be useful for builders using OnFinality infrastructure to get started on Ethereum, the home to thousands of dApps!

Why Build On Ethereum?

Ethereum is the world’s second largest cryptocurrency after Bitcoin. But more than just a digital payment method, Ethereum is also a marketplace for financial services, games, social networks and a whole slew of other decentralised applications.

“Following the merge, the Ethereum network is now more energy-efficient, scalable and secure. OnFinality’s easy to use and highly-scalable RPC API support will enable web3 builders to easily deploy dApps and introduce a host of new features to the network in a matter of clicks.”

— Daniel Vulinovich, Product Manager at OnFinality

Our Enhanced API Service has been serving over 1 Billion JSON RPC requests to its public API service every day across multiple Layer-1 ecosystems, and its 99.9% uptime is why over 60 networks rely on OnFinality.

Since our founding in 2019, we’ve served over 287 Billion requests across Layer-1 chains, including some of the largest projects on Polkadot like Astar, Kusama and Moonbeam, as well as all chains on Avalanche and chains within the Cosmos ecosystem.

What Is Ethereum? ($ETH)

Ethereum is a technology for building apps and organisations, holding assets, transacting and communicating without being controlled by a central authority.

Ethereum being programmable means that you can build apps that use the blockchain to store data or control what your app can do.

This results in a general purpose blockchain that can be programmed to do anything. As there is no limit to what Ethereum can do, it allows for great innovation to happen on the Ethereum network.

What Are Some Key Concepts About Ethereum

Open-Source With Smart Contract Functionality

‘Smart contracts’ on Ethereum are programs stored on a blockchain made to automatically run once a predetermined set of conditions are met, removing the need of a middleman for transactions, and preventing agreements from being altered/ meddled with.

Proof Of Stake Consensus Mechanism

‘The Merge’ that took place on 15 September 2022, transitioned the network from a model of Proof of Work (PoW) to Proof of Stake (PoS), with the former relying on mining to earn rewards and the latter relying on staking one’s tokens to verify new blocks and earn rewards.

ETH VS ERC20 VS Ethereum Gas

ETH (aka “Ether”) is Ethereum’s native token, used to pay for transactions on the network. ERC20 is a token standard within the Ethereum ecosystem for executing smart contracts. Gas is a fee that all users have to pay to perform any function on Ethereum.
