# EthContract
A set of helper methods to help query ETH smart contracts
## Installation
If [available in Hex](https://hex.pm/docs/publish), the package can be installed
by adding `eth_contract` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:eth_contract, "~> 0.1.0"}
]
end
```
Documentation can be generated with [ExDoc](https://github.com/elixir-lang/ex_doc)
and published on [HexDocs](https://hexdocs.pm). Once published, the docs can
be found at [https://hexdocs.pm/eth_contract](https://hexdocs.pm/eth_contract).
## Configuration
Add your JSON RPC provider URL in config.exs
```elixir
config :ethereumex,
url: "http://"
```
## Usage
Load and parse the ABI
```
abi = EthContract.parse_abi("crypto_kitties.json")
```
Get meta given a token_id and method name
```
EthContract.meta(%{token_id: 45, method: "getKitty", contract: "0x06012c8cf97BEaD5deAe237070F9587f8E7A266d", abi: abi})
```
This will return a map with all the meta:
```
%{ "birthTime" => 1511417999,
"cooldownIndex" => 0,
"generation" => 0,
"genes" => 626837621154801616088980922659877168609154386318304496692374110716999053,
"isGestating" => false,
"isReady" => true,
"matronId" => 0,
"nextActionAt" => 0,
"sireId" => 0,
"siringWithId" => 0
}
```
