IDO auction explained

IDO contracts follow the model of dutch auction. There are two versions of IDO contracts — one runs “daily” auctions, the other runs “weekly” ones. In fact, these auctions are expected to last 1 day or 1 week, but they can last longer or shorter if some special criteria are met (see the max_price and min_price criteria below).

  • 30% of “weekly” rewards become available after the end of a round immediately and 70% are locked for 1 year.
  • max_price of 0.186 * 1.6 = $0.297

Description/Documentation mismatch explained

At the moment of the IDO launch we had multiple variations of the contract discussed.
