Minting Tokens

Minting creates new native tokens on Cardano. Every mint requires a minting policy — either a Plutus script or a native script — that authorizes which tokens can be created and under what conditions.

How It Works

Define the tokens to mint (policy ID + asset name + quantity)
Attach the minting policy script
Provide a redeemer (for Plutus policies)
Build, sign, submit — the builder handles the rest

Positive quantities mint tokens. Negative quantities burn them.

Mint with a Plutus Policy

import { , , ,  } from "@evolution-sdk/evolution"

const  = .()
  .({
    : "https://cardano-preprod.blockfrost.io/api/v0",
    : ..!
  })
  .({ : ..!, : 0 })

declare const : any // compiled Plutus minting policy (from Aiken build or Blueprint codegen)

// Mint 1000 tokens
const  = "7edb7a2d9fbc4d2a68e4c9e9d3d7a5c8f2d1e9f8a7b6c5d4e3f2a1b0"
const  = "4d79546f6b656e" // "MyToken" in hex
let  = .(0n)
 = .(, , , 1000n)

const  = await 
  .()
  .({
    ,
    : .(0n, []), // Minting action
    : "mint-my-token"
  })
  .({ :  })
  .()

const  = await .()
await .()

Mint and Send in One Transaction

Mint tokens and immediately send them to a recipient:

import { , , , ,  } from "@evolution-sdk/evolution"

const  = .()
  .({
    : "https://cardano-preprod.blockfrost.io/api/v0",
    : ..!
  })
  .({ : ..!, : 0 })

declare const : any // compiled Plutus minting policy (from Aiken build or Blueprint codegen)

const  = "7edb7a2d9fbc4d2a68e4c9e9d3d7a5c8f2d1e9f8a7b6c5d4e3f2a1b0"
const  = "4d79546f6b656e"

let  = .(0n)
 = .(, , , 1n)

let  = .(2_000_000n) // Min ADA for UTxO
 = .(, , , 1n)

const  = await 
  .()
  .({
    : ,
    : .(0n, []),
  })
  .({ :  })
  .({
    : .("addr_test1vrm9x2dgvdau8vckj4duc89m638t8djmluqw5pdrFollw8qd9k63"),
    : 
  })
  .()

const  = await .()
await .()

Burn Tokens

Use negative quantities to burn tokens you hold:

import { , , ,  } from "@evolution-sdk/evolution"

const  = .()
  .({
    : "https://cardano-preprod.blockfrost.io/api/v0",
    : ..!
  })
  .({ : ..!, : 0 })

declare const : any // compiled Plutus minting policy (from Aiken build or Blueprint codegen)

const  = "7edb7a2d9fbc4d2a68e4c9e9d3d7a5c8f2d1e9f8a7b6c5d4e3f2a1b0"
const  = "4d79546f6b656e"

// Negative quantity = burn
let  = .(0n)
 = .(, , , -500n)

const  = await 
  .()
  .({
    : ,
    : .(1n, []), // Burn action
    : "burn-tokens"
  })
  .({ :  })
  .()

const  = await .()
await .()

What the Builder Handles

When minting, Evolution SDK automatically:

Tracks the minting policy via its policy ID
Indexes mint redeemers correctly after coin selection
Includes the minting policy in the script data hash
Evaluates the minting policy to compute execution units
Calculates fees including script execution costs

Next Steps

Locking to Script — Lock minted tokens to a script address
Asset Units — Understanding policy IDs and asset names
Asset Metadata — Attach CIP-25 NFT metadata
Reference Scripts — Store minting policies on-chain
