Fantom – RPC Documentation | Blockchain Gateway

The Fantom RPC documentation provides developers with detailed instructions to interact programmatically with the Fantom blockchain. Through its API endpoints, developers can query blockchain data, submit transactions, and manage smart contracts using the Fantom network. Leveraging its asynchronous Byzantine Fault Tolerance (aBFT) consensus mechanism, Fantom delivers near-instant finality and high throughput, making it an ideal blockchain for decentralized finance (DeFi) and scalable decentralized applications (dApps).
