Best Smart Contract Platforms for Synapse Protocol

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.

BNB Smart Chain (BSC) is a blockchain platform developed by Binance, designed to enable decentralized applications (dApps) and smart contracts. It operates as a parallel chain to Binance Chain, combining high-speed transactions with the programmability of Ethereum-compatible smart contracts. BSC uses a Proof-of-Staked-Authority (PoSA) consensus mechanism, which enhances scalability and efficiency while reducing transaction costs. It is compatible with the Ethereum Virtual Machine (EVM), allowing developers to easily port dApps and projects from Ethereum. BSC has become a popular choice for decentralized finance (DeFi), gaming, and NFT ecosystems, offering users a fast, low-cost, and secure platform for blockchain-based innovations.

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.

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.

The new scalability stack for Ethereum. Instant transactions and scalable smart contracts. Optimism is a Public Benefit Corporation (PBC): a for-profit corporation intended to produce a public benefit and operate in a responsible and sustainable manner. This means that we are obligated to balance the pecuniary interests of our stockholders with the best interests of those materially affected by our conduct, as well as a specific "public benefit charter" we incorporated with. The specific public benefit purpose of the Company is to enhance and enshrine fair access to public goods on the internet through the development of open source software. This charter represents our pledge to the Ethereum community to uphold its values by producing infrastructure which promotes the growth and sustainability of an ecosystem of public goods.

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.
