Native Transactions

You can send DEM using the Demos sdk as shown below:

1. Connect to the network

import { Demos, DemosWebAuth } from "@/websdk"

// Connect to the network
const rpc = "https://demosnode.discus.sh"
const demos = new Demos()
await demos.connect(rpc)

// Create and connect your wallet
const identity = DemosWebAuth.getInstance()
await identity.create()
await demos.connectWallet(identity.keypair.privateKey as Uint8Array)

2. Create a transaction

You can now create a transaction by passing the address and the amount to demos.transfer.

// 2. Create a transaction
const tx = await demos.transfer(
    "0x6690580a02d2da2fefa86e414e92a1146ad5357fd71d594cc561776576857ac5",
    100,
)

The transcation returned by demos.transfer is signed using the wallet connected to the demos object.

demos.transfer is an alias to demos.pay

3. Send the transaction

// Confirm the transaction
const validityData = await demos.confirm(tx)
console.log("Validity data", validityData)

// Broadcast the transaction
const broadcastRes = await demos.broadcast(validityData)
console.log("Broadcast result", broadcastRes)

Hacking

The demos.transfer method calls the main transfer function, passing the connected wallet to sign the transaction.

To sign the transaction using a different private key, you can call the tranfer function directly as shown:

import { DemosTransactions } from "@/websdk"

// Create the keypair
const identity = DemosWebAuth.getInstance()
await identity.create()

// Sign the transaction using the keypair
const tx = await DemosTransactions.transfer(
    "0x6690580a02d2da2fefa86e414e92a1146ad5357fd71d594cc561776576857ac5",
    100,
    identity.keypair,
)
