NaPoleonX contracts

Design

Crowdsale

The entry point. Contributors send ether to this address. Depending on whether the contributor is whitelisted, the ether is transfered to PendingContributions or to WhitelistedGateway

Pending

Contributions are stored in PendingContributions. Their transfer to the gateway can be retried, succeeding if they are now whitelisted.

Gateway

The gateway is connected to the Whitelist to let Crowdsale and Pending knwo whether a contribution is valid. When it gets a contribution, it forwards the amount to the Vault and emits an event to keep track of contribution sources and amounts.

Vault

The existing NPX vault.

4. Set up the connection to an Ethereum node. Make sure you control the address at index 0.
5. Run truffle migrate
