Bianchetto is an Ethereum Developer Framework for iOS
- Please note that it's at a very early stage, therefore there's still a lot to be done.
- It has only been tested with TestRPC running locally.
- Executions of multiple arguments functions hasn't been properly tested and it'll probably crash.
Just drop the folllowing files and folders into your project:
- Bianchetto.swift
- RPC
- Tools
Bianchetto has two main parts: the JSON RPC API interface as the defined at the JSON RPC API specification and the framework.
From this specification only the following methods are implemented:
- web3_clientVersion
- web3_sha3
- net_version
- net_peerCount
- net_listening
- eth_protocolVersion
- eth_syncing
- eth_coinbase
- eth_mining
- eth_hashrate
- eth_gasPrice
- eth_accounts
- eth_blockNumber
- eth_getBalance
- eth_getStorageAt
- eth_getTransactionCount
- eth_getCompilers
- eth_sendTransaction
- eth_newFilter
- eth_getLogs
The following improvements are pending and planned:
- Complete all the methods.
- For some of the implemented methods results can be formatted to be more friendly (e.g. eth_getStorageAt and eth_getTransactionCount)
The executeFunction
method is intended to emulate Truffle's functionality.
but it's still limited to only two ABI types: string
and uint256
, nevertheless
still can only manage values that don't exceed 32 bytes.
The following improvements are pending and planned:
- Complete all the types in the Ethereum Contract ABI specification.
- Allow for values greater than 32 bytes.
function update(string newMessage) {
message = newMessage;
}
It executes the update
function with the Test String
value for the newMessage
argument, from the 0xdbd5cc227eab854a53108dbcee38245e1582bb80
account to the contract with the 0xddee8fbd7d0c5d119d44ac1af31a8d4d7121870a
address deployed to a locally hosted testRPC.
