For some context, here is a related discussion from last year: Proposal: Add support for 1INCH Token.
At the time, @monet-supply brought up some risk concerns that have since been addressed by the implementation of the following:
1. 1INCH vesting contract
The Step Vesting contract allows for the on-chain distribution of vested 1INCH based on the predetermined vesting schedule – v1INCH is the token used to represent vesting 1INCH. This improves transparency to the vested 1INCH distribution.
2. 1INCH supply concentration
The total holdings of 1INCH and v1INCH by the 1inch Foundation’s mulit-sig is now only ~17 of the total supply instead of the 88% of the supply cited in the original discussion thread.
3. 1INCH mint function burned
On April 6th, 2022 the 1inch Foundation burned the mint function of 1INCH with this transaction.
