This is primarily a set of foundry scripts that are designed to make it very easy to get quotes for a particular payload using a variety of routes, completely offchain. It supports performing quotes from a specific source chain to N destination chains, or performing full mesh enumeration for a set of chains so you can identify the cheapest routes.

LayerZeroQuoter was designed using Foundry, so I recommend familiarizing yourself with that if required.

• Install Foundry

  curl -L https://foundry.paradigm.xyz | bash
  foundryup

1. Clone this repo:

   git clone https://github.com/Zodomo/LayerZeroQuoter
   cd LayerZeroQuoter
   

2. Install LayerZeroQuoter:

   forge install
   

3. Install LayerZero-v2 dependencies

   cd lib/LayerZero-v2
   yarn
   yarn build
   cd ../..
   

4. Copy .env.example into .env:

   cp ./.env.example ./.env
   

5. Populate the RPC URLs for the chains you want to test in .env, save it, and then run:

   source .env

1. Pick any of the scripts in ./scripts/ and modify the variables near the top of the script you want to run.
   MeshQuote.s.sol:

   uint128 internal gas = 50_000; // Must be in units of gas, not in gwei
   uint128 internal msgValue = 0.01 ether;
   bytes internal message = abi.encode("Zodomo");
   bool internal payInLzToken = false;

   OutboundQuote.s.sol:

   uint32 internal srcEid = EID_MAINNET; // Source this in src/LZConfig.sol
   uint128 internal gas = 50_000; // Must be in units of gas, not in gwei
   uint128 internal msgValue = 0.01 ether;
   bytes internal message = abi.encode("Zodomo");
   bool internal payInLzToken = false;

   InboundQuote.s.sol:

   uint32 internal dstEid = EID_MAINNET; // Source this in src/LZConfig.sol
   uint128 internal gas = 50_000; // Must be in units of gas, not in gwei
   uint128 internal msgValue = 0.01 ether;
   bytes internal message = abi.encode("Zodomo");
   bool internal payInLzToken = false;

2. Comment and/or uncomment each _deploy() call in the specified script's setUp() function to configure which chains you are testing.
   Example:

   _deploy("Ethereum", vm.envString("ETHEREUM_RPC_URL"), EID_ETHEREUM);
   //_deploy("BNB Chain", vm.envString("BNB_RPC_URL"), EID_BNB);
   //_deploy("Avalanche", vm.envString("AVALANCHE_RPC_URL"), EID_AVALANCHE);
   _deploy("Polygon", vm.envString("POLYGON_RPC_URL"), EID_POLYGON);
   _deploy("Arbitrum", vm.envString("ARBITRUM_RPC_URL"), EID_ARBITRUM);
   _deploy("Optimism", vm.envString("OPTIMISM_RPC_URL"), EID_OPTIMISM);

3. Lastly, execute your preferred script using one of the following commands (be careful not to broadcast, as that is not necessary).
   

   forge script script/InboundQuote.s.sol --sig "run()" -vvv

   forge script script/OutboundQuote.s.sol --sig "run()" -vvv

   forge script script/MeshQuote.s.sol --sig "run()" -vvv
