Prerequisites

• Rust (stable)
• wasm32v1-none target: rustup target add wasm32v1-none
• Stellar CLI: cargo install --locked stellar-cli

---

Build and Optimization

To build all contracts and optimize the generated WASM files, run the provided script:

./build-all.sh

This requires stellar-cli to be installed for the stellar contract optimize command.

---

Deploying to Testnet

1. Deploy the Launchpad contract:

stellar contract deploy \
  --wasm target/wasm32v1-none/release/soroban_launchpad.wasm \
  --source <YOUR_ACCOUNT> \
  --network testnet

2. Deploy the desired collection WASM (e.g., ERC-721) to get its WASM hash:

stellar contract install \
  --wasm target/wasm32v1-none/release/collection_nft_erc721.wasm \
  --source <YOUR_ACCOUNT> \
  --network testnet

3. Initialize the Launchpad with the returned WASM hash.
4. Invoke the launchpad contract to deploy a new collection, and it will return the address of the newly deployed collection.
