Functions

address(name)

Returns the current Contract GenServer's address

at(name, address)

Sets the address for the contract specified by the name argument

call(contract_name, method_name, args \\ [], timeout \\ :infinity)

Use a Contract's method with an eth_call

child_spec(init_arg)

Returns a specification to start this module under a supervisor.

deploy(name, args)

Deploys contracts with given arguments

deploy_helper(bin, abi, args)

eth_call_helper(address, abi, method_name, args)

eth_send_helper(address, abi, method_name, args, options)

filter(contract_name, event_name, event_data \\ %{})

Installs a filter on the Ethereum node. This also formats the parameters, and saves relevant information to format event logs.

from_block_helper(event_data)

get_event_attributes(state, contract_name, event_name)

get_filter_changes(filter_id)

Using saved information related to the filter id, event logs are formatted properly

init(state)

Callback implementation for GenServer.init/1.

Registers the contract with the ContractManager process. Only :abi is required field.

send(contract_name, method_name, args, options)

Use a Contract's method with an eth_sendTransaction

start_link(_ \\ :ok)

Begins the Contract process to manage all interactions with smart contracts

tx_receipt(contract_name, tx_hash)

Returns a formatted transaction receipt for the given transaction hash(id)

uninstall_filter(filter_id)

Uninstalls the filter, and deletes the data associated with the filter id
