Foundry deployment

This package includes two Foundry scripts to deploy the LSP8CustomizableTokenInit and LSP8MintableInit implementation contracts.

• scripts/DeployLSP8CustomizableTokenInit.s.sol
• scripts/DeployLSP8MintableInit.s.sol

Set your deployer key first:

export PRIVATE_KEY=0x...

Dry run against LUKSO Testnet
