Uport-Proxy

Proxy contracts for uPort & identity systems. Proxy contracts are a way of maintaining a persistent identifier/address on a system. The Proxy contract will interact with other smart contract and it has access control that allows the user to replace and rotate private keys while maintaining a persistent identfier.

More info on Proxy contracts

• Core Proxy contract is: Proxy.sol

Interesting Owner contracts are

OwnerWithAdmin

Owner contract with an User key that controls the proxy contract. There is also an Admin key that can unilaterally replace the User key.

OwnerWithMetaTx

Owner contract that implements Metatransactions (see the document above for more info).

IdentityFactory

The IdentityFactory creates a proxy contract with an associated controller. When a new identity is created an event is fired.

Deployed contract

The IdentityFactory is deployed on the ConsenSys testnet at the address

0xebe809bb9c515914f41e16cf500a15d31869c1e8

Example usage

You can watch the event to see when an identity has been created from a specific address.

var identityfactoryContract = web3.eth.contract([{"constant":false,"inputs":[{"name":"userKey","type":"address"},{"name":"adminKey","type":"address"}],"name":"CreateProxyWithController","outputs":[],"type":"function"},{"anonymous":false,"inputs":[{"indexed":true,"name":"creator","type":"address"},{"indexed":false,"name":"proxy","type":"address"},{"indexed":false,"name":"controller","type":"address"}],"name":"IdentityCreated","type":"event"}]);
var proxyContract = web3.eth.contract([{"constant":false,"inputs":[{"name":"_owner","type":"address"}],"name":"transfer","outputs":[],"type":"function"},{"constant":false,"inputs":[{"name":"addr","type":"address"}],"name":"isOwner","outputs":[{"name":"","type":"bool"}],"type":"function"},{"constant":true,"inputs":[],"name":"owner","outputs":[{"name":"","type":"address"}],"type":"function"},{"constant":false,"inputs":[{"name":"destination","type":"address"},{"name":"value","type":"uint256"},{"name":"data","type":"bytes"}],"name":"forward","outputs":[],"type":"function"}]);
var ownerwithadminContract = web3.eth.contract([{"constant":true,"inputs":[],"name":"userKey","outputs":[{"name":"","type":"address"}],"type":"function"},{"constant":false,"inputs":[{"name":"newUserKey","type":"address"}],"name":"updateUserKey","outputs":[],"type":"function"},{"constant":true,"inputs":[],"name":"adminKey","outputs":[{"name":"","type":"address"}],"type":"function"},{"constant":false,"inputs":[{"name":"destination","type":"address"},{"name":"value","type":"uint256"},{"name":"data","type":"bytes"}],"name":"sendTx","outputs":[],"type":"function"},{"constant":true,"inputs":[],"name":"proxy","outputs":[{"name":"","type":"address"}],"type":"function"},{"constant":false,"inputs":[{"name":"newAdminKey","type":"address"}],"name":"updateAdminKey","outputs":[],"type":"function"},{"constant":false,"inputs":[{"name":"newOwner","type":"address"}],"name":"transferOwnership","outputs":[],"type":"function"},{"inputs":[{"name":"proxyAddress","type":"address"},{"name":"_userKey","type":"address"},{"name":"_adminKey","type":"address"}],"type":"constructor"}]);

var identityFactory = identityfactoryContract.at([deployed address])

var proxyAddress;
var controllerAddress;
var creatorAddress = '0x123..';
var event = identityFactory.IdentityCreated({creator: creatorAddress}, function(error, result) {
        proxyAddress = result.args.proxy;
        controllerAddress = result.args.controller;
    });

var proxy = proxyContract.at(proxyAddress);
var controller = ownerwithadminContract.at(controllerAddress);

Testing

Tests are run using truffles framework. -install truffle and testrpc -Have testrpc running in background -Then: $ truffle test
