Token Transfer

The tokenTransfer() function creates a user operation for transferring tokens. This function initiates the process of transferring a token by encoding the necessary parameters into a User Operation, which can then be signed and executed using the OktoClient.

There are two ways to implement token transfers:

Abstracted Flow: A simplified approach where the user operation is automatically created, signed, and executed in a single step. Perfect for most applications.
UserOp Flow: A granular approach where you manually control the creation, signing, and execution of the user operation. Useful for custom implementations or advanced use cases.

Example

import { tokenTransfer } from "@okto_web3/core-js-sdk"; 
 
async function handleTokenTransfer() {
    try {
        const transferParams = { 
            amount: BigInt("1000000000000000000"), // 1 token with 18 decimals 
            recipient: "0x742d35Cc6634C0532925a3b844Bc454e4438f44e", 
            token: "0x2170ed0880ac9a755fd29b2688956bd959f933f8", // Token contract address 
            caip2Id: "eip155:1"
        }; 
 
        // Execute the transfer
        const jobId = await tokenTransfer(oktoClient, transferParams); 
        console.log('Transfer jobId:', jobId);
    } catch (error) {
        console.error('Error in token transfer:', error);
    }
}
