Token Minter (Anchor)

Note

This is the Anchor v2 copy of this example. Every anchor command on this page needs the v2 CLI: cargo install anchor-cli --version 2.0.0-rc.1 --locked (avm has no prebuilt binary for this pre-release). The Anchor v1 version of this example is in ../anchor-v1.

Mint tokens from inside your program using the Classic Token Program.

See also: Token Minter overview and the repository catalog.

Major concepts

  • Mint authority on a PDA or signer
  • Token account initialization
  • Amounts: mint_token takes amount in minor units, the raw integer the token program operates on. Clients convert from major units offchain: 1 token with 9 decimals is 1 * 10^9 minor units. The program never scales amounts onchain.

Setup

From this directory (tokens/token-minter/anchor/):

anchor build

Prerequisites: Agave CLI (version in Anchor.toml [toolchain]), Anchor.

Testing

Tests run in-process with LiteSVM. No local validator.

anchor test

This runs cargo test as configured in Anchor.toml. Tests call instruction handlers and check onchain state.

Usage

Read the program programs/ source and Anchor.toml for deployed program IDs. For deployment, use anchor build && anchor deploy against your target cluster.
