Installation

$ npm install @layerzerolabs/ua-devtools-evm-hardhat

The plugin depends on @nomiclabs/hardhat-ethers, so you need to import both plugins in your hardhat.config.js:

require("@nomiclabs/hardhat-ethers");
require("@layerzerolabs/ua-devtools-evm-hardhat");

Or if you are using TypeScript, in your hardhat.config.ts:

import "@nomiclabs/hardhat-ethers";
import "@layerzerolabs/ua-devtools-evm-hardhat";

Make sure that network names in your hardhat.config.js match the following naming convention.

Tasks

The package adds the following tasks:

• getDefaultConfig returns the default configuration for the specified chains.

  Usage:

  pnpm hardhat getDefaultConfig --networks ethereum,bsc,polygon,avalanche

• getConfig returns the configuration of the specified contract.

  Parameters:

  • address - the contract address. An optional parameter. Either contract name or contract address must be specified.
  • name - the contract name. An optional parameter. It must be specified only if the contract was deployed using hardhat-deploy and the deployments information is located in the deployments folder.
  • network - the network the contract is deployed to.
  • remote-networks - a comma separated list of remote networks the contract is configured with.

  Usage:

  pnpm hardhat getConfig --network ethereum --remote-networks bsc,polygon,avalanche --name OFT

• setConfig sets the configuration of the specified contract.

  Parameters:

  • config-path - the relative path to a file containing the configuration.
  • address - the address of the deployed contracts. An optional parameter. It should be provided if the contract address is the same on all chains. For contracts with different addresses, specify the address for each chain in the config.
  • name - the name of the deployed contracts. An optional parameter. It should be provided only if the same contract deployed on all chains using hardhat-deploy and the deployment information is located in the deployments folder. For contracts with different names, specify the name for each chain in the config.
  • gnosis-config-path - the relative path to a file containing the gnosis configuration. An optional parameter. If specified, the transactions will be sent to Gnosis.

  Usage:

  pnpm hardhat setConfig --networks ethereum,bsc,avalanche --name OFT --config-path "./appConfig.json" --gnosis-config-path "./gnosisConfig.json"

      "name": "ProxyOFT"
    },
    "contractConfig": {
      "name": "OFT"
    },
    "chainConfig": {
      "avalanche": {
        "defaultFeeBp": 2,
        "useCustomAdapterParams": true,
        "remoteNetworkConfig": {
          "ethereum": {
            "feeBpConfig": {
              "feeBp": 5,
              "enabled": true
            },
            "minDstGasConfig": {
              "packetType_0": 100000,
              "packetType_1": 200000
            }
          },
          "polygon": {
            "minDstGasConfig": {
              "packetType_0": 100000,
              "packetType_1": 160000
            }
          }
        }
      }
    }
  }

  The proxyContractConfig is an optional setting, that defines the proxy chain and proxy contract name.

  • chain: An optional string, defines the proxy chain.

  • name: An optional string, defines the proxy contract name.

  • address: A optional string, defines the contract address. Used when deployments folder are not available. Uses standard LzApp/Nonblocking/OFT/ONFT abi calls such as:

    • function setFeeBp(uint16, bool, uint16)
    • function setDefaultFeeBp(uint16)
    • function setMinDstGas(uint16, uint16, uint)
    • function setUseCustomAdapterParams(bool)
    • function setTrustedRemote(uint16, bytes)

  • The contractConfig is a conditionally required setting, that defines the contract name.

    • function setFeeBp(uint16, bool, uint16)

  • The chainConfig: is required and defines the chain settings (default fees, useCustomAdapterParams) and the remote chain configs (minDstGas config based of packetType, and custom feeBP per chain)

    • name: A conditionally required string, defines the contract name. Used when contract names differ per chain.

    • address: A conditionally required string, defines the contract address. Used when deployments folder are not available. Uses standard LzApp/Nonblocking/OFT/ONFT abi calls.

    • defaultFeeBp: An optional number, defines the default fee bp for the chain. (Available in OFTV2 w/ fee.)

    • useCustomAdapterParams: An optional bool that defaults to false. Uses default 200k destination gas on all cross chain messages. When false adapter parameters must be empty. When useCustomAdapterParams is true the minDstGasLookup must be set for each packet type and each chain. This requires whoever calls the send function to provide the adapter params with a destination gas >= amount set for that packet type and that destination chain.

    • remoteNetworkConfig is a conditionally required setting, that defines the contract name. - minDstGasConfig: is an optional object that defines the minDstGas required based off packetType. So for example when the UA on Avalanche sends packet type 0 to Ethereum the minDstGas will be 100000. When the UA on Avalanche sends packet type 1 to Polygon the minDstGas will be 160000. - The feeBpConfig is an optional setting that defines custom feeBP per chain. (Note: setting custom fee per chain with enabled = TRUE, will triumph over defaultFeeBp.) - feeBp: is an optional number, defines custom feeBP per chain. - enabled: is an optional bool, defines if custom feeBP per chain is enabled

    Below is an example of the Gnosis configuration

    {
      "ethereum": {
        "safeAddress": "0xa36B7e7894aCfaa6c35A8A0EC630B71A6B8A6D22",
        "url": "https://safe-transaction.mainnet.gnosis.io/"
      },
      "bsc": {
        "safeAddress": "0x4755D44c1C196dC524848200B0556A09084D1dFD",
        "url": "https://safe-transaction.bsc.gnosis.io/"
      },
      "avalanche": {
        "safeAddress": "0x4FF2C33FD9042a76eaC920C037383E51659417Ee",
        "url": "https://safe-transaction.avalanche.gnosis.io/"
      }
    }

    For each chain you need to specify your Gnosis safe address and Gnosis Safe API url. You can find the list of supported chains and API urls in Gnosis Safe documentation.
