How to Mint More SPL Tokens Using Portal API (Solana)

✅ Step 1: Understand What “Minting” Means

In Solana, “minting” means creating new tokens under the same token contract (or “mint address”) you already created. It’s like printing more money—except digitally and with full control.

🔧 Step 2: Know What You Need

You’ll use the /blockchain/token/mint endpoint. Here’s what you need to provide:

chain: Always "SOL" for Solana

tokenAddress: The mint address of your token (the ID from when you first created the token)

to: The wallet address where the new tokens will go

amount: How many tokens to mint

from: The wallet that has authority to mint (must match the one used in creation)

fromPrivateKey: The private key to authorize the transaction

🧪 Step 3: Sample API Request

json

Copy

Edit

POST /blockchain/token/mint

{

"chain": "SOL",

"tokenAddress": "YOUR_TOKEN_MINT_ADDRESS",

"to": "USER_WALLET_ADDRESS",

"amount": "50000",

"from": "YOUR_WALLET_ADDRESS",

"fromPrivateKey": "YOUR_PRIVATE_KEY"

}

This request says:

“Mint 50,000 more tokens from my existing SPL token contract, and send them to a specific wallet.”

📦 Step 4: What You’ll Get Back

You’ll get a JSON response that includes:

Edit

{

"txId": "2t1qkN...8zH1o"

}

This is your transaction ID—you can look it up on Solana explorers to confirm the minting went through.

🛠️ Best Practices

🔐 Keep your private key safe—never expose it publicly.

💸 Make sure your wallet has SOL to pay for the transaction.

🎯 Double-check the wallet address you're minting to—no takebacks in blockchain!

🧭 What Can You Do After Minting?

Here’s what’s next:

Distribute tokens to users, partners, or DAO members

Track transactions via Solana block explorers

Update token metadata if needed

Monitor circulation for transparency
