Setup

Setup IconExtension with magic-sdk

import { Magic } from 'magic-sdk';
import { IconExtension } from '@magic-sdk/extension-icon';

const magic = new Magic('YOUR_API_KEY', {
    extensions: {
        icon: new IconExtension({

        })
    }

See the developer documentation to learn how you can master the Magic SDK in a matter of minutes.

Usage

Get account

Using getAccount function to get Icon public address for current user.

const publicAddress = await magic.icon.getAccount();
console.log('icon public address', publicAddress);

Send Transaction

Build the transaction object using builder class.

    /* Build `IcxTransaction` instance for sending ICX. */
    const txObj = new IconBuilder.IcxTransactionBuilder()
                .from("hxe4837d3b902dcaf9abe529f5584489c28d8b4621")
                .to("hxe4837d3b902dcaf9abe529f5584489c28d8b4621")
                .value(IconAmount.of(0.5, IconAmount.Unit.ICX).toLoop())
                .stepLimit(IconConverter.toBigNumber(100000))
                .nid(IconConverter.toBigNumber(3))
                .nonce(IconConverter.toBigNumber(1))
                .version(IconConverter.toBigNumber(3))
                .timestamp((new Date()).getTime() * 1000)
                .build();
    
    /* Build `MessageTransaction` instance for sending data. */
    const txObj = new IconBuilder.MessageTransactionBuilder()
                  .from('hxe4837d3b902dcaf9abe529f5584489c28d8b4621')
                  .to('hxe4837d3b902dcaf9abe529f5584489c28d8b4621')
                  .stepLimit(IconConverter.toBigNumber(1000000))
                  .nid(IconConverter.toBigNumber(3))
                  .nonce(IconConverter.toBigNumber(1))
                  .version(IconConverter.toBigNumber(3))
                  .timestamp((new Date()).getTime() * 1000)
                  .data(IconConverter.fromUtf8('Hello'))
                  .build();
           
    /* Build `DeployTransaction` instance for deploying SCORE. */
    const txObj = new DeployTransactionBuilder()
                .from('hxe4837d3b902dcaf9abe529f5584489c28d8b4621')
                .to('cx0000000000000000000000000000000000000000')
                .stepLimit(IconConverter.toBigNumber(2100000000))
                .nid(IconConverter.toBigNumber(3))
                .nonce(IconConverter.toBigNumber(1))
                .version(IconConverter.toBigNumber(3))
                .timestamp((new Date()).getTime() * 1000)
                .contentType('application/zip')
                .content(`0x${content}`)
                .params({
                    initialSupply: IconConverter.toHex('100000000000'),
                    decimals: IconConverter.toHex(18),
                    name: 'StandardToken',
                    symbol: 'ST',
                })
                .build();
    
    /* Build `CallTransaction` instance for executing SCORE function. */
    const txObj = new IconBuilder.CallTransactionBuilder()
                .from('hxe4837d3b902dcaf9abe529f5584489c28d8b4621')
                .to('cxd1602bde1d4b2b4facc8673c661c5e59e6ac20b4')
                .stepLimit(IconConverter.toBigNumber('2000000'))
                .nid(IconConverter.toBigNumber('3'))
                .nonce(IconConverter.toBigNumber('1'))
                .version(IconConverter.toBigNumber('3'))
                .timestamp((new Date()).getTime() * 1000)
                .method('hello')
                .params({})

By passing txObj instance to magic.icon.sendTransaction() method, it will automatically sign the transaction with current user and generate transaction object including signature, then send to ICON node.

    const txhash = await magic.icon.sendTransaction(txObj);

    console.log('transaction result', txhash);
    window.open(`https://bicon.tracker.solidwallet.io/transaction/${txhash}`)
