Simple contract interaction example

This repository reproduces an example of interaction between contracts in Etherlink which finished with error.

This repository contains two simple smart contracts written in solidity:

• Counter: which allows to setNumber to any uint256 and increment number
• Caller: which allows to setNumber for a given counter contract providing its address as one of the parameters

To use this repository, you need to install foundry: https://github.com/foundry-rs/foundry

Usage

Build

$ forge build

Test

$ forge test

Deploy in Etherlink

$ forge create --legacy --rpc-url https://evm.ghostnet-evm.tzalpha.net/ --private-key <your_private_key> src/Counter.sol:Counter --gas-limit 100000
$ forge create --legacy --rpc-url https://evm.ghostnet-evm.tzalpha.net/ --private-key <your_private_key> src/Caller.sol:Caller --gas-limit 100000

After deploy you will get your caller_address and counter_address. Here is some contracts that already deployed in Etherlink:

• Counter: 0x833696e136d0A66206615a5f84F4097F1c8802F8
• Caller: 0xc7D3B0d10151054831561B8e868467a8CFE0BaC0

Communicate

cast send <caller_address> "setNumber(address, uint256)" <counter_address> 420 --rpc-url https://evm.ghostnet-evm.tzalpha.net/ --private-key <your_private_key> --legacy --gas-limit 300000

Example with deployed caller and counter:

cast send 0xc7D3B0d10151054831561B8e868467a8CFE0BaC0 "setNumber(address, uint256)" 0x833696e136d0A66206615a5f84F4097F1c8802F8 420 --rpc-url https://evm.ghostnet-evm.tzalpha.net/ --private-key <your_private_key> --legacy --gas-limit 300000
