Tools for Gnosis ICO:
- constracts/proxysender.sol: smart contract to collect ethers from different users and proxy ico bids
- bidProxy.js: small tool that wait for ico start and immediatelly call bidProxy() on the ProxySender contract
The tool requires an ethereum node on main network, rpc enabled, accound 0 unlocked with some ethers to pay transaction fees. Run:
./bidProxy.js <proxy_address>
where <proxy_address> is the address of an istance of the ProxySender smart contract initialized with the address of the official DutchAuction smart contract for gnosis ico.
Reminder: to start a node (geth or parity) with an unlocked account use the --unlock <address> --password <file> parameters.
The simulation works only with TestRPC node because it requires the evm_increaseTime rpc method
to skip the 1 week waiting period at the end of the auction.
Run ethereum node:
testrpc
Run ICO simulation:
truffle test test/ico_simulation.js
Before deploying the ProxySender smart contract, a DutchAuction instance is required and it must be initialized with the token address (the setup() method). ProxySender constructor requires the DutchAuction address as argument.
Steps:
- Before ICO start, users send own ethers to the ProxySender smartcontract using a normal transaction.
- Before ICO start, users can ask a refund calling the
refund()method. - After ICO start,
bidProxy()must be called to send funds to the ICO contract (the bidProxy tool can be used). - After ICO end,
claimProxy()must be called to reclaim tokens for the proxy. - After the tokens are reclaimed for the proxy, users reclaim own tokens sending a normal transaction with value 0 to the proxy address
Use the following method ids in the data field of transaction to call the contract methods:
ed9a3ac1 bidProxy()
30b66cee claimProxy()
590e1ae3 refund()
