Sui RPC
What is Sui?
Sui is a high-performance layer-1 blockchain focused on low-latency transaction processing and horizontal scalability. Built around the Move programming language, it enables fast finality and high throughput for on-chain applications like gaming, finance, and real-time experiences. Developers write smart contracts in Move, a Rust-based language designed for secure and efficient execution.
Interacting With Sui APIs
Sui exposes JSON-RPC and gRPC interfaces that allow developers to interact with the blockchain programmatically. You can query objects and transactions, submit transactions, inspect Move modules, and monitor network activity.
You can connect by running your own Sui node with the appropriate interfaces enabled, or by using a hosted provider such as QuickNode, which offers reliable, low-latency access without the need to manage infrastructure.
