Hedera Token Minting

Hedera Token Minting (HTS)

Setup

npm install @hashgraph/sdk

Create Fungible Token

import { 
  TokenCreateTransaction, 
  TokenSupplyType,
  TokenType 
} from '@hashgraph/sdk';
const tx = await new TokenCreateTransaction()
  .setTokenName("My Token")
  .setTokenSymbol("MTK")
  .setTokenType(TokenType.FungibleCommon)
  .setSupplyType(TokenSupplyType.Infinite)
  .setDecimals(2)
  .setInitialSupply(1000000) // Total supply = 1,000,000
  .setTreasuryAccountId(treasuryId)
  .setAdminKey(adminKey)
  .setSupplyKey(supplyKey)
  .freezeWith(client)
  .sign(treasuryKey);
const result = await tx.execute(client);
const tokenId = result.receipt.tokenId;

Create NFT Collection

const tx = await new TokenCreateTransaction()
  .setTokenName("My NFT Collection")
  .setTokenSymbol("MNFT")
  .setTokenType(TokenType.NonFungibleUnique)
  .setTreasuryAccountId(treasuryId)
  .setAdminKey(adminKey)
  .setSupplyKey(supplyKey)
  .freezeWith(client)
  .sign(treasuryKey);

Mint NFTs

import { TokenMintTransaction } from '@hashgraph/sdk';
const tx = await new TokenMintTransaction()
  .setTokenId(tokenId)
  .addMetadata(Buffer.from("NFT #1 metadata"))
  .addMetadata(Buffer.from("NFT #2 metadata"))
  .freezeWith(client)
  .sign(supplyKey);
const result = await tx.execute(client);

Token Operations

Transfer Token

import { TransferTransaction } from '@hashgraph/sdk';
await new TransferTransaction()
  .addTokenTransfer(tokenId, fromAccount, -10)
  .addTokenTransfer(tokenId, toAccount, 10)
  .execute(client);

Burn Tokens

import { TokenBurnTransaction } from '@hashgraph/sdk';
await new TokenBurnTransaction()
  .setTokenId(tokenId)
  .setAmount(100)
  .execute(client);
