Build Securely on Midnight with OpenZeppelin

OpenZeppelin brings its trusted libraries to Compact, Midnight’s TypeScript-inspired smart contract language. Built for privacy and compliance, these standards enable developers to create applications that safeguard data across DeFi, NFTs, identity, and Real-World Assets.

pragma language_version >= 0.14;

import CompactStandardLibrary;
import "openzeppelin-compact/token/FungibleToken" prefix FungibleToken_;

export ledger owner: Bytes<32>;

constructor(initialOwner: Bytes<32>) {
  owner = initialOwner;
  FungibleToken_initialize("MyToken", "MTK", 18);
}

export circuit mint(to: Either<ZswapCoinPublicKey, ContractAddress>, amount: Uint<128>): [] {
  FungibleToken__mint(to, amount);
}
