RMRK Lazy Minting Proxy Contract

This is a proxy contract for RMRK to enable lazy minting.

Purpose

RMRK is designed in a way that all tokens in collection needs to be pre-minted and equipped with assets to be useful, which increases costs for a collection creators. This contract enables lazy token minting on RMRK contract. The proxy contract has single method mint which does the following:

• mints RMRK token
• adds random asset to the token
• transfers the token to the method caller

To be able to use this contract some prerequisites (see e2e test for details) must be met:

• RMRK and catalog contracts are deployed
• parts added to the catalog contract (catalog::addPartList)
• asset entries added to the RMRK contract (call multiAsset::addAssetEntry for each entry you want to add)

🏗️ How to use - Contracts

💫 Build

• Use this instructions to setup your ink!/Rust environment

cd rmrk_proxy
cargo contract build --release

💫 Run unit and integration tests

cd rmrk_proxy
cargo test --features e2e-tests -- --nocapture

💫 Deploy

First start your local node. Recommended is the latest swanky-node

./target/release/swanky-node --dev --tmp -lruntime=trace -lruntime::contracts=debug -lerror

Use

• polkadot.JS. Instructions on Astar docs
• or Contracts UI

to deploy contract on the local Swanky node
