GameItemONFT1155

This contract implements the ONFT standard and ERC1155 so that token holders can bridge their NFTs and equip them against simulated attacks with other holders

/**
 * @title GameItemONFT1155
 * @notice A simple ERC1155 implementation with the following functionality
 * - permissioned mints
 * - token owners can equip a single NFT to represent them during a "battle" with another token owner
 * - token owners can bridge their NFT to another supported chain (via layerzero)
 */

Deploy

To deploy our GameItemONFT1155 contract on both chains:

npx hardhat deploy-onft --network mumbai

npx hardhat deploy-onft --network goerli

Set Trusted Remote

Before our GameItemONFT1155 contract on either chain can receive messages, we must set the trusted remote on both chains:

npx hardhat set-trusted-onft --network mumbai --remote goerli

npx hardhat set-trusted-onft --network goerli --remote mumbai

Simulate + Bridge

Simulate the typical user flow with a series of transactions, which involve a bridge of our GameItemONFT1155 token

npx hardhat simulate-bridge-onft --network mumbai --remote goerli

1. we mint ourselves an NFT
2. this NFT is auto-equipped for attacks
3. we estimate the fee for sending our token to another chain
4. we bridge our NFT to a destination chain, paying a native fee. this burns our NFT on the source chain
5. we can check LayerZero Scan to validate that our message was relayed
6. if we attempt to attack another player with our NFT on the source chain, we'll see that it reverts because our token was burned

on the destination chain, we can attack another player with our newly minted NFT

npx hardhat simulate-bridge-onft --network goerli --remote mumbai --attack

GameItemONFT721

This contract implements the ONFT standard and ERC721 so that token holders can bridge their NFTs and equip them against simulated attacks with other holders

/**
 * @title GameItemONFT721
 * @notice A simple ERC721 implementation with the following functionality
 * - permissioned mints
 * - token owners can equip a single NFT to represent them during a "battle" with another token owner
 * - token owners can bridge their NFT to another supported chain (via layerzero)
