Interoperability Between EVM-based Blockchains

This project contains "demonstration" smart contracts for defining semantics in interoperability between blockchains based on Ethereum Virtual Machine (EVM). The source code refers to the publication Interoperability Between EVM-based Blockchains

Smart contracts include use cases:

• Token Transfer (ERC20 and ERC721)
• Data synchronization
• Cross-chain execution of smart contracts

Configure truffle.js

In order to correctly deploy smart contracts, the truffle.js file must be configured by specifying the private keys of the accounts responsible for the deployments in the different chains. (privateKeyChainA, privateKeyChainB). Once this is done, you must specify the blockchains on which you want to deploy. In particular, for each blockcahin it is necessary to indicate the chain ID, the gas to be used, the connection URL and the address (it must relate to the private keys specified above).

Install node modules

After the configuration is done, it is necessary to install all node modules and dependencies. To do so type from the main directory:

$ npm install

If the installation ends correctly, it is possible to deploy all smart contracts under the contract folder by executing the compileDeployContracts.sh under the scripts folder.

NOTICE: If you want to deploy and tests the smart contracts on Remix it is necessary to update the Openzeppelin dependencies. To do so you have to modify the Initiator, Finalizer, SimpleERC20Token and SimpleERC721Token smart contracts as follows:

• Initiator and Finalizer: replace the {Strings} import with:
  • import {Strings} from "@openzeppelin/[email protected]/utils/Strings.sol";
• SimpleERC20Token: replace the ERC20 import with:
  • import "@openzeppelin/[email protected]/token/ERC20/ERC20.sol";
• SimpleERC721Token: replace the ERC721 import with:
  • import "@openzeppelin/[email protected]/token/ERC721/ERC721.sol";
  • import "@openzeppelin/[email protected]/token/ERC721/extensions/ERC721Burnable.sol";
