Comprehensive Ethereum developer platform for real-time monitoring, alerting, debugging, and simulating Smart Contracts. Sort and group transactions by any parameter you want and make it easier to explore and analyze robust data. Inspect the transaction execution with a couple of clicks and instantly find the line your transaction reverted on. See the state of your contract at any point in a transaction and explore state changes in a granular view. Visualize and analyze the behavior of your Smart Contract to spot patterns and gain a deeper insight into transaction data. Any time an event triggers your custom set of rules you will receive a notification on your favorite channels like Slack, Email, PagerDuty, etc. Get a granular gas usage breakdown to help you optimize your Smart Contracts and lower the gas cost of your transactions. Know how your transactions will behave before you execute them, estimate the gas usage and test potential bug fixes.

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.

Create powerful decentralized applications with API3’s decentrally governed and quantifiably secure data feeds. API3 data feeds, dAPIs, aggregate data from first-party oracles, operated by some of the world’s premier API providers. Decentralized, trust-minimized and transparent governance. First-party oracles instead of third-party middlemen. Users insured against data feed malfunctions. Real-world data for any smart contract platform. API3 data feeds are governed by an open DAO of stakeholders, industry experts and project partners. This allows dAPIs to be operated with maximal transparency, minimal required trust in centralized operators, and no centralized attack surfaces. API token holders can take a direct part in governing the project by staking API3 tokens into the API3 insurance staking contract, which grants them shares in the API3 DAO.

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.

At Zilliqa, we leverage on our silicon-smooth, speedy and cost-effective blockchain platform to catalyze and transform digital infrastructure across all global communities and industries. We're committed to delivering a scalable and secure platform for developers and enterprises who wish to build decentralized applications. Our unique application of sharding allows the blockchain to scale in a linear fashion. This ensures that the Zilliqa platform can scale to meet the needs of a growing ecosystem of miners and applications. Zilliqa is powered by the first peer- reviewed and safe-by-design smart contract language called Scilla. Using functional programming design principles (as in OCaml) allows it to be more friendly towards static checks and formal verification. Thanks to Zilliqa's consensus mechanism, the ecological footprint of mining has considerably been reduced. Only 1 minute out of every 2-3 hours is needed to mine ZIL, allowing one to dual-mine other chains at the same time.

Darwinia Network provides an entrance to the Polkadot ecology for projects that have been deployed on public blockchains such as Ethereum and BSC. Darwinia Smart App is compatible with the Ethereum virtual machine, and supports DApps such as Defi and NFT, which can be easily migrated to Polkadot. Darwinia network can bring users a very high-quality experience, including very low transaction fees and ultra-fast transaction confirmation speed. Darwinia Network has a sound governance system where all token holders can submit proposals. Upgrades to the network are coordinated on-chain and enacted autonomously, ensuring that Darwinia’s development reflects the values of the community and avoids stagnation. The native tokens for Darwinia Network are RING, KTON. KTON is a derivative commitment token of RING, which encourages long-term involvement. Darwinia Network is a blockchain technology company, established in Singapore, 2018.

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.
