Standards (Vara Token Programs)

This workspace contains extended implementations of three token standards for the Vara network, built with the Sails framework.:

• extended-vft: Fungible Token with role-based access control (admins, minters, burners)
• extended-vmt: Multiple Token (semi-fungible, ERC-1155-like) with roles and per-token metadata
• extended-vnft: Non‑Fungible Token with roles and rich on-chain/off-chain metadata support

Each standard exposes a base *-service crate with core storage and logic and an app crate that composes and extends it with additional functionality and events. Clients can be generated via sails-rs for type-safe contract calls.

Workspace layout

extended-vft/          # VFT program (base + app + client)
extended-vmt/          # VMT program (base + app + client)
extended-vnft/         # VNFT program (base + app + client)
vft-service/           # Base service for VFT
vmt-service/           # Base service for VMT
vnft-service/          # Base service for VNFT

Build

Build all workspace members in release mode:

cargo build -r

Build a specific program (example: extended VFT):

cargo build -r -p extended-vft

Note: extended-* crates include the app Wasm via a build script; building the top-level crate is sufficient to produce artifacts.

Test

Unit and regular tests:

cargo test -r

Some integration tests rely on a local node and are marked ignored. To run all tests (including gclient ones), make sure a node binary is available and then:

cargo test -r -- --ignored

Roles and permissions (high level)

• Admins: Can grant/revoke admin/minter/burner roles
• Minters: Can mint tokens
• Burners: Can burn tokens

Role checks are enforced in exported methods; unauthorized calls panic with a clear message.

Deploying on Vara

For a concise end‑to‑end guide to running programs on Vara (building, uploading Wasm, instantiation), follow the official documentation: Getting started in 5 minutes.

Public CodeIds

You can instantiate your own token programs using the public CodeIds below. The instantiating account becomes the initial admin/minter/burner where applicable.

Tip: Click the corresponding [link] for Mainnet or Testnet to open the Gear IDEA portal. In IDEA → Codes, paste (or it will already be prefilled, if supported) the CodeId and click Create Program.
