View Source Ethers.Contract (Ethers v0.4.5)

Dynamically creates modules for ABIs at compile time.

How to use

You can simply create a new module and call use Ethers.Contract in it with the desired parameters.

# Using an ABI file
defmodule MyProject.Contract do
  use Ethers.Contract, abi_file: "path/to/abi.json"
end

# Providing a default address
defmodule MyProject.Contract do
  use Ethers.Contract, abi_file: "path/to/abi.json", default_address: "0x1234...999"
end

# Using an ABI directly
defmodule MyProject.Contract do
  use Ethers.Contract, abi: [%{"inputs" => [], "type" => "constructor"}, ...]
end

After this, the functions in your contracts should be accessible just by calling

data = MyProject.Contract.example_function(...)

# Use data to handle eth_call
Ethers.call(data, to: "0xADDRESS", from: "0xADDRESS")
{:ok, [...]}

• skip_docs: Determines if Ethers should skip generating docs and typespecs. (Default: false)
