Polkadot's cross-consensus messaging format (XCM) enables secure communication between blockchains, including the dapps built on top of them. You can not only transfer tokens and NFTs, but program advanced functionality and tap into Web3 integrations across multiple use-case optimized chains.
Choose from multiple smart contract platforms for your dapp and leverage custom functionality across multiple chains, including Ethereum. Deploy existing Solidity code or write advanced Wasm-based contracts in ink!, Polkadot's native Rust-based eDSL. Get low fees that you can predict ahead of time with Polkadot's flexible gas model.
Polkadot provides an advanced browser-based light client with an accompanying browser extension. This enables developers to build dapps in a more decentralized way, with no need to rely on third-party RPC nodes for interacting with the blockchain.
Upgrade your project to its own custom layer-1 blockchain for industry-grade optimization and scalability, and get bank-like security for your chain from day 1 thanks to Polkadot's shared security model. Customizing your own chain gives you better performance and user experience, and you can even customize your fee model and predict your production costs.
With Substrate (#PolkadotSDK), Polkdot's blockchain development framework, get unmatched time-to-market with a custom chain by leveraging pre-built modules for common functionality, so you can focus on developing your own custom business logic. Stay ahead of the curve with advanced capabilities like open governance, light clients and secure interoperability.
Upgrading a blockchain shouldn't be any more difficult than upgrading conventional software. With Polkadot, your chain gets seamless, forkless upgrades out of the box, so you can continually improve your technology and keep up with the pace of innovation. With Polkadot’s customizable on-chain governance, your upgrades get enacted automatically on-chain.
