Token Transfer

Send CROSS

Function to transfer native CROSS tokens.

import { useAppKitAccount, SendController } from '@to-nexus/sdk/react'

const RECEIVER_ADDRESS = "0xB09f7E5309982523310Af3eA1422Fcc2e3a9c379"
const SEND_CROSS_AMOUNT = 1

function sendCross() {
  const account = useAppKitAccount()
  if (!account?.isConnected) return

  SendController.sendNativeToken({
    receiverAddress: RECEIVER_ADDRESS,
    sendTokenAmount: SEND_CROSS_AMOUNT,
    decimals: '18'
  })
}

Send ERC20

Function to transfer ERC20 tokens.

import { useAppKitAccount, SendController, useAppKitNetwork } from '@to-nexus/sdk/react'

const ERC20_ADDRESS = "0x6892a97F4E85D45f4CaCAfBc5fc0B5186f355A1b"
const RECEIVER_ADDRESS = "0xB09f7E5309982523310Af3eA1422Fcc2e3a9c379"
const SEND_ERC20_AMOUNT = 1

function sendERC20() {
  const account = useAppKitAccount()
  const network = useAppKitNetwork()
  if (!account?.isConnected) return

  const ERC20_CAIP_ADDRESS = `${network.caipNetworkId}:${ERC20_ADDRESS}`
  SendController.sendERC20Token({
    receiverAddress: RECEIVER_ADDRESS,
    contractAddress: ERC20_CAIP_ADDRESS,
    sendTokenAmount: SEND_ERC20_AMOUNT,
    decimals: '18'
  })
}

Transaction Status

Functionality to monitor transaction status.

import { useAppKitAccount, SendController } from '@to-nexus/sdk/react'

function sendTransaction() {
  const account = useAppKitAccount()
  if (!account?.isConnected) return

  const resTx = SendController.sendNativeToken({
    receiverAddress: RECEIVER_ADDRESS,
    sendTokenAmount: 1,
    decimals: '18'
  })

  resTx.on('pending', () => console.log('Pending'))
  resTx.on('confirmed', () => console.log('Confirmed'))
  resTx.on('failed', () => console.log('Failed'))
}

Gas Estimation

Functionality to estimate gas fees before sending a transaction.

import { useAppKitAccount, ConnectionController } from '@to-nexus/sdk/react'

function GasEstimator() {
  // Get account state
  const account = useAppKitAccount()
  
  // Handle gas estimation
  async function estimateGas() {
    // Check if wallet is connected
    if (!account?.isConnected) {
      alert('Please connect wallet first.')
      return
    }

    // Estimate gas for ERC20 transfer
    const gasEstimate = await ConnectionController.estimateGas({
      contractAddress: ERC20_ADDRESS,
      method: 'transfer',
      abi: sampleErc20ABI,
      args: [RECEIVER_ADDRESS, SEND_ERC20_AMOUNT_IN_WEI]
    })

    console.log('Estimated gas:', gasEstimate)
  }

  return <button onClick={estimateGas}>Estimate Gas</button>
}
