- Create and manage tokens on Hedera (HTS). Use for: (1) Minting fungible tokens, (2) Creating NFTs (HTS), (3) Setting up token supplies, (4) Configuring token permissions.
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);
Key Points
- Supply Types:
Infinite or Finite - Token Types:
FungibleCommon or NonFungibleUnique - Royalty: Use custom fees for NFT royalties
- Token ID Format:
0.0.12345
