README

        
ethers.objc

===========

Everything you need to write your own Ethereum wallet and interact with the blockchain.

Please note this documentation is a work in progress, with many stubs and place holders. The bulk of the documentation is being put together in a readthedocs RST document and this is just to help out a (very) little in the meantime.

**Features:**

- Simple and complete public API

- Ready-to-go; drop the framework into your project and you are off to the races

- Full testnet support

- Geth Secret Storage Wallet support

- BIP39 + BIP32 + BIP44 support (SLIP 44)

- ICAP + checksum address support

- Multiple providers and meta-providers

- Secure; all private keys are stored in self-clearing memory

- A large test suite to ensure correctness against other libraries

- Open Source (MIT Licensed)

API

===

To use the Framework, add the ethers.Framework to your project and add:

```obj-c

@import ethers;

```

Fundamentals

------------

**Account**

An account contains a private key used to sign transactions and prove ownership of an account.

- Import/Export Geth Secret storage wallets

- Generate and import BIP 39 mnemonic wallets (m/44'/60'/0'/0/0)

**Provider**

- A provider is used to connect to the blockchain.

Common Objects

--------------

**Address**

- Checksum Addresses

- IBAN/ICAP Addresses

**BigNumber**

- Explain why we need to use Bignumbers

**Hash**

- BlockHash

- TransactionHash

**Promise**

- Async

- Chainable and able to make a dependency tree

Detail Objects

--------------

**Transaction**

- Serialize and deserialize transactions

- EIP155 support

**TransactionInfo**

- Information (possibly incomplete) about a transaction

**BlockInfo**

- Information about a block

Providers

---------

**EtherscanProvider**

- Connects to the [Etherscan](https://etherscan.io) API endpoints.

**InfuraProvider**

- Connect to [INFURA](https://infura.io) with an optional API Access Token.

**JsonRpcProvider**

- Connect to any Parity, Geth, et cetera node.

**FallbackProvider**

- On error, try the next provider in the list.

**RoundRobinProvider**

- Randomly selects from a list of providers, with fallback.

**LightWalletProvider**

- Experimental

- Still a lot of issues with the iOS Geth library (and xgo)

- Makes the phone VERY hot

Utilities

---------

**SecureData**

- Create NSMutableData backed objects with a SecureAllocator to zero the memory when deallocated.

- Convenience methods for operating on hex strings

**Payment**

- Convert between ether value strings and wei

- Parse payment URI

To Do

=====

**Contract API**

Still need an equivalent to the Ethers.Contract object to parse an ABI, and generate ABI encoders/decoders.
