💵 vCASH Stablecoin

New types of stablecoins are needed in order to create a more stable and secure DeFi ecosystem. That’s where vCASH comes in.

What is vCASH?

vCASH is our new kind of stablecoin introduced by MonoX, it is the glue that holds the protocol together. Our protocol solves the capital inefficiencies of liquidity pool pairs by grouping deposited tokens into a virtual pair with the vCASH stablecoin. This allows us to offer single token pools whereby the user only needs to deposit one token to the pool instead of two. vCASH is backed by all the assets in MonoX pools that have a positive vCASH balance.

When a user first deposits liquidity to create a new pool, they set a starting price for the asset. This means that every asset in MonoX pools expresses their value in vCASH. Therefore trading works by forming a similar pricing curve to Uniswap except while they use the ratio between two tokens, we have a starting price and a would be price.

Pricing

If a user sells from the starting price the asset depreciates in value, if someone buys from the starting price the asset appreciates in value. As such, we use starting price and would be price instead of the ratio between Token A and Token B in the xy=k constant product formula. Our pricing algorithm is based on Uniswap’s model found here. However in this calculation vCASH supply is equal to infinity which programs it to have no slippage and always peg to USD 1:1.

How To Get vCASH

Users can swap any ERC token directly to vCASH.

When users withdraw liquidity, they will receive vCASH if the stablecoin virtual balance is positive in an official pool.

How is vCASH Backed?

The pair is virtual. vCASH is a real stablecoin. vCASH is technically backed by all the assets in the pool. However, it’s more accurate to say that it is backed by the sell function because when a user sells into vCASH it mints the physical stablecoin. In essence, vCASH is backed by the liquidity itself, not the assets. vCASH is only backed when there is a positive vCASH balance in the pool. Trustless listing pools cannot go below 0 for vCASH balance.

How does vCASH hold its peg?

All the assets in the pools express their value in terms of vCASH. The supply of vCASH is fixed at infinity which pegs 1:1 with USD.

How would vCASH lose its peg?

If several different assets were artificially held at a price different to the market price, it would cause the vCASH to lose its peg. However, vCASH would retain its peg as arbitrageurs would step in to trade the differences if the assets are not priced similarly to what’s on the market.

Can I use vCASH?

Yes, you can mint vCASH by trading directly into it.
