Subzero Tokens (SUB) are designed to be used as a medium of exchange. The built-in stability mechanism in the protocol aims to maintain SUB's peg to 0.01 AVAX.

Note that SUB actively pegs via the algorithm, it does not mean it will be valued at 0.01 AVAX at all times, as it is not collateralized. SUB is not to be confused for a fiat-backed stablecoin.

Subzero tokens can be used to provide liquidity and earn yield or they can be frozen to Absolute Zero to earn ecosystem rewards.

ZShares (ZSHAREs) are the pinnacle token of the Subzero ecosystem. ZShares serve as the governance token of the ecosystem and are used for Regulation staking. Regulation is the highest level of yield in the protocol, while SUB is over peg (0.01 AVAX).

Subzero has a sustainable, long-term approach to share token distribution. Since the launch of the V2 contracts, the emissions were cut in half. And as of a vote in January 2023, ZShares were put on an annual halving schedule.

  • 2024 Supply: 40,008 (+11,600)

  • 2025 Supply: 45,808 (+5,800)

  • 2026 Supply: 48,708 (+2,900)

  • 2027 Supply: 50,158 (+1,450)

  • 2028 Supply: 50,883 (+725)

  • 2029 Supply: 51,245.5 (+362.5)

  • 2030 Supply: 51,426.75 (+181.25)

During epoch expansions the protocol automatically regulates it's supply. When SUB is trading above the peg (0.01 AVAX), SUB tokens are minted in order to help bring the price back to peg. The newly minted SUB tokens are distributed proportionally to all ZShare holders who have staked their tokens via Regulation.

Z Bonds (ZBONDs) main job is to help incentivize changes in the SUBZERO supply during an epoch contraction period. When the TWAP (Time Weighted Average Price) of SUB falls below 0.01 AVAX, ZBONDs are issued and can be bought with SUB at the current price. Exchanging SUB for ZBOND burns the SUB tokens, taking them out of circulation (deflation) and helping to get the price back up to 0.01 AVAX.

These ZBONDs can be redeemed for SUB when the price is above peg in the future, plus an extra incentive when the price is further above peg. This amounts to inflation and sell pressure for SUB tokens when it is above peg, helping to push it back toward 0.01 AVAX. ZBONDs do not have expiration dates.

All holders are able to redeem their ZBOND for SUB tokens as long as the treasury has a positive SUB balance, which typically happens when the protocol is in epoch expansion periods.

Absolute Zero (ABZERO) is a unique type of revenue share token in our ecosystem. It serves to control circulation, maintain the peg and benefit the most loyal and steadfast holders in the Subzero ecosystem. On top of ZBONDs, ABZERO allows a more significant portion of the total supply to be frozen, which can make reaching peg comparatively easier than in other protocols.

Absolute Zero is freely interchangeable with Subzero via The Freezer contract. The value of the ABZERO token will increase compared to SUB even without staking and this is tracked via the index. Freezing has a tax of 3% and defrosting has a tax of 17%, fully distributed to ABZERO holders.

You will always be able to remove the number of Subzero tokens you are entitled to, and the contract will never "fall short." The Freezer generates income based on a separate Rewards Pool contract which feeds SUB tokens into the Freezer on the same rebase timer as the Regulation rewards. Because of this, the Freezer does not generate any additional inflation, and it will primarily be funded by the Subzero ecosystem.

One additional benefit of The Freezer is that a Regulation contribution (of 15%) has been re-routed to this contract. The ABZERO rebase occurs both above and below peg, but the returns will be higher when above peg. ABZERO holders earn 0.25-1.00% of the Rewards Pool each day. The rewards are lower when below peg and higher when consistently above peg (APR increases when above peg for more than 4 epochs). ABZERO can also be single staked for ZSHARE rewards.
