We are looking for a few white hats to test a new trading platform (similar to Bittrex, Poloniex, etc.) which we have been developing for over a year and are close to launching. We are particularly looking to identify and correct any exploits which are known to have been used on exchanges in the past. There are many examples. (https://magoo.github.io/Blockchain-Graveyard/). In particular, vulnerabilities such as the Polo hack where two withdrawals done immediately after each other would result in both going through and a resulting negative balance for the exchange and any attack on the hot wallets.  We’re also interested in testing and hardening our customer service verification procedures.

We have a decent budget for this work so please get in touch if you have the relevant skills and this is of interest to you. I am also happy to provide more details on myself, the project and some other successful ventures we have previously done in the blockchain space. We are looking for this work to begin immediately.
