Sigmoid launch plan(outdated)

***This plan is outdated, new launch plan involved with institutional investors will be announced soon.


A model of a competitive decentralized monetary system. In this model, the supply of the currency (SASH) is regulated by an algorithm, in consideration of the market demand, velocity, price, and exchange rate. Our model is built upon a set of economic rules, which will allow our system to always recover genuinely from recession.

  • SASH (sigmoid cash) is a new generation algorithmic sustainable stable-coin.apply for Whitelist.
  • The price of SASH has the tendencies to return to a projected price.
  • The MA value of SASH to USD will always increase. It has no upper limit.
  • SASH is Death Spiral resistant. SASH has his own economic cycle, it can always recover from recession.
  • For start SASH is only partially pledged by USD, SASH bondholders will never suffer from permanent loss.
  • The minting of SASH applies Fisher‘s quantity theory of money (MV=PT).

SASH is bond based. The only way to mint SASH, is to deposit a stable coin into a bank contract. By doing so the investor will receive SASH bond. On the redemption date, bondholders will receive their SASH reward and their principal.

We propose a new ERC(BEP) Bonds standard. Which allows all kinds of bonds to be created and traded on a secondary market. Every single bond has their own interest rate, redemption date and conditions of redemption. Bonds are printed by depositing tokens into bank contracts. Bonds can be redeemed; the bondholder will receive their principal and interest. The interest is in the form of a token (settlement token) which is associated with the bond. The redemption date is calculated from the velocity and the market demand of the settlement token. Bonds can only be traded on Sigma bond exchange.

ERC(BEP)659 standard and Sigma bonds exchange open a whole new market for investors and speculators alike. In this market of limitless potential, SIGMA protocol is the first standard maker.

Launch and Distribution

Sigmoid Protocol will be launched separately on BSC, ETH and HECO. There will be in four phases of distribution. The protocol will be first launched on BSC.

Phase zero, Whitelist+Airdrop 4th April, 2021 - 4th June,2021

(*The end phase 0 extends from 5th May, 2021 to 4th June,2021)

During Phase 0, before the distribution of SASH and SGM, a whitelist will be established. The whitelist contains a collection of the addresses that will be allowed to participate in Phase 1. Every address have a maximum deposit limit, which is decided by how much the address owner is involved during Phase 0. People who gives useful advise and helps promote Sigmoid protocol will have the first places in the list. Then, those who participated in other major DEFI projects. During this phase everyone can apply for the airdrop of SASH. The airdrop can be claimed after the start of phase 1, it will be locked from the start, and will be unlocked gradually as the total supply of SASH growth. When the total supply of SASH reach 66.6 times of the total Airdrop amount, The airdrop will be fully unlocked.

  • apply for Airdrop.
  • apply for Whitelist.
  • Learn about Sigmoid protocol and ERC-659 bonds.
  • The audit will be hosted before the start of phase 1.

Phase one, initial liquidity providing for SASH

As mentioned above, during the phase 1, the address on the whitelist will be allowed to deposit USD to earn SASH. The participant will not be requested to buy SASH in order to participate in the farming. The yield farming of SASH is single token based, which means you only need to deposit a single token to farm SASH.

  • Only the address on the whitelist can deposit once during phase 1.
  • the amount they deposit must not exceed the maximum amount that they will be allowed.
  • There will be 4 USD pools to farm SASH, BUSD, USDT, USDC, DAI.
  • Any tokens listed on Pancake swap will be allowed to participate by converting to USD.
  • If a single deposit exceed 50,000 USD, the participant will not be needed on the Whitelist.
  • During the Phase 1 everyone can buy SASH from SASH-USD LP. But it will be at least twice the price of the Whitelist participants.
  • The deposit of SASH for SGM(sigmoid governance token) will also be open during this stage.
  • The SASH reward from first liquid providing will be locked until the start of phase 3.
  • The SASH reward can be used to farm SGM. The farming of SGM is also single token based.

Phase two, initial liquidity providing opens to all

In Phase 2, the yield farming of SASH will be open to all. The minimum minting cost of SASH and SGM will grow as the total supply of SASH grows. The participants of phase 1 can collect their SGM reward. Those SGM can be used for community governance. The participation in governance will also generate SASH reward.

  • Any address can participate once during phase 1.
  • There will be 4 USD pools to farm SASH, BUSD, USDT, USDC, DAI.
  • Any tokens listed on Pancake swap will be allowed to participate by converting to USD.
  • All limits on participation will be removed (including per address and per pool).
  • Non-stablecoin pools can be created by community voting.

Phase three, fully launched

in Phase 3, the SASH reward of previous phases will be unlocked. Market will be allowed to decide the initial price of SASH and SGM.

  • All early reward will be unlocked.
  • SGM and SASH will be listed on major exchanges.
  • The launching of Sigmoid protocol on ETH and HECO will be announced.
