# STK

> STK is the fixed-supply Stockline token.

STK is the fixed-supply Stockline token. The constructor mints the whole supply once, to the deploy script, which then sends each slice of the published allocation table: auction, treasury, supplier emissions, backstop, and team vesting. There is no owner and no mint function. Any holder can burn, which is how `FeeCollector.buyAndBurn` shrinks supply. STK is not collateral and is not the borrow asset.

`STK` lets you:

* Hold and transfer STK as a standard 18-decimal ERC-20
* Burn your own STK, or STK you are approved to spend
* Read a supply that can only go down

Addresses per network. Every address is also on [Addresses](/resources/addresses).

| Network                 | Address                                                                                                                                       |
