white paper

Shrew stands for SHopping REWards, an ecosystem that will aim to simplify and connect stores from all over the world. In the process, we will create a network that will allow anyone, around the globe to seamlessly earn, store and spend SHREW at any store. Opening up possibilities for both the stores and the consumer.

The platform where users can bring in existing rewards accounts, earn points using a single app for multiple stores and trade these points with others using blockchain. The SHREW token will be the single currency linking each reward scheme across a multitude of stores and will thus have deep utility and value.

Shrew2.handleTax(address,address,uint256) (#890-994) uses timestamp for comparisons
Dangerous comparisons:
- tax > 0 (#904)
- tax > 0 (#918)
- taxSum == 0 (#929)
- ethValue >= swapThreshold (#933)
- remainingTokens > 0 (#970)
- ethGained - (marketingETH + communityETH + liquidityETH + charityETH) > 0 (#978)
Avoid relying on block.timestamp.
