Best Smart Contract Platforms for Xircus

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.

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.

Polygon is a leading blockchain infrastructure designed to bring the speed, scalability, and efficiency of the internet to global finance. With over 5 billion transactions, 117 million active addresses, and a 99.99% uptime record, Polygon has become the trusted foundation for real-time payments, stablecoin transfers, and decentralized finance. The network enables instant settlement at near-zero cost, powering billions in digital asset movement worldwide. Its enterprise-ready infrastructure includes built-in wallets, onramps, and compliance tools that simplify blockchain adoption for businesses. Powered by POL, Polygon’s native token fuels transactions, staking, and security across its multi-chain ecosystem. Built for scalability, Polygon delivers the reliability and performance that modern financial systems demand.

Harmony is an open and fast blockchain. Our mainnet runs Ethereum applications with 2-second transaction finality and 100 times lower fees. Harmony’s secure bridges offer cross-chain asset transfers with Ethereum, Binance and other chains. Harmony serves as a platform for creators to connect with their community. Harmony’s bridges can connect any Proof-of-Work and Proof-of-Stake chains. Our FlyClient architecture are fully trustless and highly gas-efficient. Currently, our bridges for Ethereum and Binance Smart Chain secure tens of millions cross-chain assets. Developers simply change Chain ID and enjoy faster EVM executions identical at the bytecode level. They can use their familiar and standard Web3 tooling to easily migrate to Harmony. What about users? They can continue to use MetaMask or Ledger — but now pay minimal fees. Any Ethereum wallets or portals can work on Harmony without code changes or new installs.

Next generation layer 2 for Ethereum dApps. Use your favorite tools and scale your dApp at the lowest cost. An aggregator plays the same role that a node plays in Ethereum. Client software can do remote procedure calls (RPCs) to an aggregator, using the standard API, to interact with an Arbitrum chain. The aggregator will then make calls to the EthBridge and produce transaction results to the client, just as an Ethereum node would. Most clients will use an aggregator to submit their transactions to an Arbitrum chain, although this is not required. There is no limit on how many aggregators can exist, nor on who can be an aggregator. To improve efficiency, aggregators will usually package together multiple client transactions into a single message to be submitted to the Arbitrum chain. Arbitrum also supports a privileged Sequencer that can order transactions and give low latency transaction receipts.
