Best Smart Contract Platforms for OnFinality

Polkadot is a blockchain network being built to enable Web 3.0, a decentralized and fair internet where users control their own data and markets prosper from network efficiency and security. Polkadot was founded in 2016 by Gavin Wood, former Co-Founder and CTO of Ethereum. Polkadot’s technology addresses the major issues that have stymied blockchain adoption in recent years. Polkadot’s software development toolkit, Substrate, created by Parity Technologies, makes it easy for blockchain developers to build their own custom, fit-for-use blockchains. Polkadot also enables multiple blockchains to communicate between each other, allows for easy upgradeability, and introduces “shared security”, a plug-and-play network security model that allows developers to focus on the technology and avoid spending time and resources recruiting a set of operators to run a new blockchain.

Ethereum is the community-run technology powering the cryptocurrency, ether (ETH) and thousands of decentralized applications. Ethereum is a technology that's home to digital money, global payments, and applications. The community has built a booming digital economy, bold new ways for creators to earn online, and so much more. It's open to everyone, wherever you are in the world – all you need is the internet. Today, billions of people can’t open bank accounts, others have their payments blocked. Ethereum's decentralized finance (DeFi) system never sleeps or discriminates. With just an internet connection, you can send, receive, borrow, earn interest, and even stream funds anywhere in the world. Today, we gain access to 'free' internet services by giving up control of our personal data. Ethereum services are open by default – you just need a wallet. Stake your ETH to become an Ethereum validator.

Unprecedented interoperability and scalability for blockchain developers who want to quickly push the limits of what’s possible. Built using Substrate with nearly the same codebase and industry-leading multichain infrastructure as Kusama’s cousin, Polkadot. The relationship between society and technology has deteriorated to the point where large entities routinely stretch and overstep their authority. Kusama is a network built as a risk-taking, fast-moving ‘canary in the coal mine’ for its cousin Polkadot. It's a living platform built for change agents to take back control, spark innovation and disrupt the status quo. Move fast and ship your product. Kusama’s risk-taking and nimble mentality allows developers to move swiftly through the governance and upgrade process, enabling rapid progress and growth. Build on a next-generation, sharded, multichain network, while employing the newest features before they are deployed on Polkadot.

Build on Avalanche. Build without limits. Avalanche is an open, programmable platform for decentralized finance applications. Launch Ethereum dapps that confirm transactions instantly and process thousands of transactions per second, far beyond any decentralized blockchain platform today. Deploy blockchains that fit your own application needs. Build your own virtual machine and dictate exactly how the blockchain should operate. Stake, or lock up, your AVAX to help process transactions and further secure the platform–providing security guarantees well-above the 51% standard. You probably have the hardware required to join the platform. Avalanche is Solidity-compatible. All of your favorite tools like Remix, Truffle, and Tenderly work out of the box. Deploying smart contracts on Avalanche cost just a tenth of what they cost on Ethereum. High gas fees, front-running, and other adverse effects of slow smart contract blockchains are now a thing of the past.

No need to rewrite or reconfigure your smart contracts. Moonbeam is much more than just an EVM implementation: it’s a highly specialized Layer 1.5 chain that mirrors Ethereum’s Web3 RPC, accounts, keys, subscriptions, logs, and more. The Moonbeam platform extends the base Ethereum feature set with additional features such as on-chain governance, staking, and cross-chain integrations. Address segments of your market that are out of reach on Ethereum due to gas prices. Enjoy a “first mover” advantage by deploying early to Polkadot’s rapidly expanding parachain ecosystem. Built-in integrations for assets like DOT and ERC-20s, and infrastructure services like Chainlink and The Graph. Moonbeam is much more than just an EVM implementation: it’s a highly specialized Layer 1 chain that mirrors Ethereum’s Web3 RPC, accounts, keys, subscriptions, logs, and more. The Moonbeam platform extends the base Ethereum feature set with additional features such as on-chain governance.

Moonriver is a companion network to Moonbeam and provides a permanently incentivized canary network. New code ships to Moonriver first, where it can be tested and verified under real economic conditions. Once proven, the same code ships to Moonbeam on Polkadot. Quickly deploy your new or existing Solidity DApps to the Moonriver parachain — with little or no modifications — and gain easy access to the Kusama network. By mirroring Ethereum’s Web3 RPC, accounts, keys, subscriptions, logs, and more, Moonriver minimizes the changes required to run existing Solidity smart contracts on the network. Ethereum projects can simply replicate their DApp and deploy it to Moonbeam using Hardhat, Truffle, Remix, and other popular deployment tools. Quickly deploy your new or existing Solidity DApps to the Moonriver parachain — with little or no modifications — and gain easy access to the Kusama network.

Scale your DApp to Polkadot with Acala, an Ethereum-compatible smart contract platform optimized for DeFi. Acala is the decentralized finance network and liquidity hub of Polkadot. It’s a layer-1 smart contract platform that’s scalable, Ethereum-compatible, and optimized for DeFi with built-in liquidity and ready-made financial applications. With its trustless exchange, decentralized stablecoin (aUSD), DOT Liquid Staking (LDOT), and EVM+, Acala lets developers access the best of Ethereum and the full power of substrate. Access DOT-based assets and derivatives, Polkadot-native decentralized stablecoin, Polkadot ecosystem assets, and cross-chain assets from Bitcoin, Ethereum and beyond. Acala’s chain is customized for DeFi and can continue to upgrade without forks to integrate new features requested from developers. For example, on-chain ‘keepers’ automate protocol execution to better manage risks and improve user experience, or transaction fees payable with virtually any token.

Discover a wide variety of dapps, contracts and tools, built in the Junø ecosystem by developers and contributors from across the globe. The Moneta Hacks are the largest incentivized smart contract challenge in the world. Developers from across the world may deploy smart contracts onto the permission-less interoperable smart contract base layer called Juno. Simple, secure and fast virtual machine set up to sandbox or partition your application’s actions for better testing, security, performance and speed. When the staking (delegation) transaction is complete, rewards will start to be generated immediately on a block per block basis. At any time, stakers can claim their accumulated rewards, via a non-custodial wallet. Juno is a completely community-owned and operated smart contract platform. The majority of the genesis supply was stake dropped to atom holders, committed to the locked community pool, and allocated to the vested development reserve & smart contract Hacks.
