CoinAlpha Fund Protocol

A blockchain protocol for tokenized hedge funds.

This open-source protocol enables asset managers to create a blockchain-based vehicle that manages capital contributed by external investors. The protocol utilizes the blockchain to perform functions such as segregated asset custody, net asset value calculation, fee accounting, and management of investor in-flows and out-flows. The goal of this project is to eliminate the setup and operational costs imposed by middlemen in traditional funds, while maximizing transparency and liquidity for investors.

For more information about the project, please see the our wiki.

Installation

Geth

Ethereum client for testnet and live

brew tap ethereum/ethereum
brew install ethereum

TestRPC

Ethereum client for local testing

npm install -g ethereumjs-testrpc

Truffle

Deployment and testing framework. Use v4.0.0-beta.0 which ships with solc v0.4.15.

npm install -g truffle@4.0.0-beta.0

Libraries and dependencies

npm install

Testing

Local

1. Run TestRPC with a 1 second block time and increased block gas limit, to allow for simulation of time-based fees: testrpc -b 1 -l 7000000
2. In another Terminal window, truffle console
3. truffle test to run all tests

Testnet

1. Run geth --testnet --rpc --rpcapi eth,net,web3,personal
2. In another Terminal window, truffle console
3. web3.eth.accounts and check that you have at least 4 accounts. Each account should have more than 5 test eth.
4. Unlock your primary account: web3.personal.unlockAccount(web3.eth.accounts[0], <INSERT YOUR PASSWORD HERE>, 15000)
5. Follow manual testing workflows in js/Fund-test.js

Ethereum Bridge | Oraclize

Ethereum Bridge is used for connecting to Oraclize from a non-public blockchain instance (e.g. testrpc). This is used for testing the DataFeed contracts.

1. In a separate folder from this repo, clone the repo: git clone https://github.com/oraclize/ethereum-bridge
2. Setup: cd ethereum-bridge; npm install
3. When running testrpc, use the same mnemonic to keep the OraclizeAddrResolver address constant: testrpc -l 7000000 -p 7545 -a 50 --mnemonic "coinalpha"
4. Run: node bridge -a 49 -H localhost:7545 --dev (-a 49 uses the 49th testrpc account for deploying oraclize; the 9th account should not be used for any other purposes, and port 7545)
5. After starting the bridge, take note of this message:

Please add this line to your contract constructor:

OAR = OraclizeAddrResolverI(0x6f485C8BF6fc43eA212E93BBF8ce046C7f1cb475);

6. Add this line into DataFeel.sol
