# oTANGO
The oTANGO interface lets you exercise your oTANGO airdrop to purchase TANGO at a discount. This page is geared towards early users of the protocol who have accrued oTANGO by using both Contano v1 and v2.
* The airdrop was designed to align incentives between the protocol and early users, and disincentivize short-term farmers. All rules were made public [here](https://medium.com/contango-xyz/tangonomics-1baadca23e81).
* The oTANGO airdrop initially allocated 18.3% of the total supply to early users who used v1 and v2 *up until the 29th of October 2024*. Since some users didn't end up claiming their share, around 3% of the supply went back to the treasury, so the final supply allocation for oTANGO is 15.3%.
oTANGO is a perpetual option token that allows you to purchase TANGO at a discount. The discount is determined by the ongoing TANGO price.
