Best Smart Contract Platforms for Swarm

Connect your smart contract with the outside world. Chainlink's decentralized Oracle network provides reliable, tamperproof inputs and outgoings for complex smart contract on any blockchain. Start building your universally connected smart contracts. To connect high-quality and accessible data/APIs to any smart contracts, use decentralization, trusted data, premium data, cryptographic proofs, and trust nodes. A flexible framework can be used to retrieve data from any API, connect to existing systems, and integrate any blockchain, both now and in the future. Integrate battle-tested and proven oracle solutions that have secured billions in value for leading blockchain projects. Independently verify Chainlink's open source code, performance of its oracle network, and quality of individual node operator.
