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.

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.

The decentralized commerce layer of the agentic economy We have solved the hard problems of decentralized commerce, so you can easily enable any agent to exchange any asset, verifiably, with low fees. Our no-code, low-cost tools make it easy to start decentralized agentic commerce in just a few clicks. With Boson dACP you can enable any agent to exchange any asset through the decentralized commerce layer of the agent stack—providing MCP-compatible infrastructure that integrates seamlessly with existing agent frameworks. Agents can autonomously handle everything from everyday purchases to high-value transactions, giving you full control of the commerce experience.

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.

Secret Network is the first blockchain with data privacy by default, allowing you to build and use applications that are both permissionless and privacy-preserving. This unique functionality protects users, secures applications, and unlocks hundreds of never-before-possible use cases for Web3. Whether you’re a developer, an artist, an entrepreneur, or a dreamer, you can become a Secret Agent and contribute to Secret Network. Check out the many contributors, collaborators, applications, and backers that make up the Secret Network ecosystem. With blockchain technology, we have the potential to create a more empowering and inclusive internet, what is often referred to as Web3. But current blockchains are public by default, exposing all data to everyone and putting users at risk. In order to enable meaningful use cases and achieve global adoption, users and organizations need control over how their data is used and shared, a concept we call programmable privacy.

Solana is a fast, secure, and censorship resistant blockchain providing the open infrastructure required for global adoption. The best projects in DeFi, Web3, and blockchain gaming choose to build on Solana for the long-term. Solana can process 50k transactions per second. Don't believe us? Stress test the network to experience Solana's speed for yourself. Say goodbye to high fees and slow confirmations. Solana is built for speed, without trade-offs. Solana leverages Proof of History and several other breakthrough innovations to allow the network to scale at the rate of Moore's Law. Never worry about rising fees as your user base grows. Solana is designed to keep fees low for applications with billions of users. Solana's single global state ensures composability between projects. Never deal with multiple shards or layer 2 systems.

TokenScript will set a new standard for token composability in a Web3 future where tokens are as ubiquitous as web pages, and where tokens will become primary objects of ownership, identity and interaction. When dApps are used as the token interface, token utility is limited. Transaction and integration logic locked in the dApp layer brings the same composability, security and availability issues that existed in Web2. Token knowledge and smart contract logic in a portable interface dramatically increases token utility. This brings context, security, interoperability and composability to tokens - not dApps. With unlimited logic and endless composability, Smart Tokens will deliver the promise of Web3. A fully-integrated web. A truly frictionless market.

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.
