How to Stake SUI Using the Mysten Labs SDK
Prerequisites
Node.js and npm installed.
SUI wallet with SUI tokens (testnet/mainnet).
Basic knowledge of TypeScript and web3.
The Sui blockchain has built-in functions for staking and unstaking in its Move modules. These functions can be directly called through the Mysten SDK's moveCall method. Below is an example of how to stake SUI to a validator using the Move function request_add_stake
Step 1: Staking SUI
To stake SUI to a validator:
Reference: The staking logic is defined in Sui's Move smart contract, which can be found here.
You can also refer to the Sui wallet app for an example of how it calls these functions in its code.
Step 2: Unstake SUI
Step 3: Testing
Run your dApp and ensure you have enough SUI for staking and gas fees.
Monitor the transaction on Sui Explorer for confirmation.
