A decentralized stock trading platform.
The Gamestop and Robinhood incident showed financial investors that they don't have full control on their financial assets. Middlemen could change the rules as they wish. We could not use our funds deposited to the platform to buy whatever we want. Selling assets was also temporarily disabled on many other platforms.
This is a problem that could be solved by Decentralized Finance (deFi). Snow Finance is a stock trading platform executing solely through smart contracts. This makes it the first stock trading platform you could 100% trust. Buying and selling stocks is automatically handled, with no middle man, no conflicts of interest, no changed rules
The buy function could always be called, as well as all other functions.
All data regarding commissions and your trade history is always publically visible.
Snow Finance also demonstrates other aspects of deFi through its Snow Vault and Snowmen NFTs
- Contracts For Difference on the Polygon Blockchain
- All trades are executed through smart contracts
- Users have full control over assets in the Snow Finance Ecosystem
- 100% Uptime
- Stock trading platform with zero rules changed
- Transparent fees and orders
- Limited supply Snowmen NFTs provide commission free trading
- Circular Liquidity flow through SNOW Coin, Snow Vault and the Stock Trading Platform
The stock trading platform is based on the contracts for difference (CFD) model. The trader places an order at a given price, and when closing the trade, the price difference is settled. If the trade is profitable for the trader, funds are sent to his wallet.
If the trade is not profitable, funds are sent to the Snow Vault.
transferValue = priceDifference * amountOfSharesThe trader also pays a 0.25% commission on closing a trade, which is transferred to the Snow Vault.
Snow Finance utilises ChainLink's 'Connect To Any API' to get stock price data onto the blockchain.
The Snow Vault is a way for users to provide liquidity to the stock trading platform.
A user can deposit MATIC to the Snow Vault and receive SNOW Coins in return.
Each Snow Coin represents a share of the funds in the Snow Vault.
SNOW Coins, ERC20 tokens, will be minted to his account. The percentage difference his MATIC deposit makes to the snow Vault will allow him to mint the same percentage amount of the Snow Coin Supply. Depositting 50% of the funds in the vault will result in 50% of Snow Coin's supply to be minted to your account.
Calling the 'WithdrawAndBurn(amount)' function in the smart contract will result in burning 'amount' Snow Coins and withdraws
(amount / total Snow Coin supply) * Funds In ContractIn Summary:
-
burning x% of the Snow Coin supply allows you to withdraw x% of the funds in the contract.
-
depositing y% of the funds in the liquidity pool allows you to mint y% of SNOW Coin's supply to your account
User's incentive to provide liquidity
All commissions from the trading platform are transferred to the Snow Vault. Snow Finance's trading platform works based on the Contracts For Difference (CFD) concept.
When a trader is profitable, funds are transferred from the Snow Vault to the trader's account.
When a trader is not profitable, funds are transferred from the trader to the Snow Vault.
Statistics say that 70 - 80% of traders make losing trades. This results in a surplus of funds placed into the Snow Vault, allowing the liquidity providers to withdraw more funds than depositted.
Users' commissions and Snowmen NFTs royalties are also added to the vault.
Snow Finance also demonstrates a way to use NFTs in financial products.
Snowmen NFT holders do not pay commission on the stock trading platform. This concept could be used by new financial products to integrate premium features in an efficient (and fun) way.
With a limited supply of Snowmen NFTs (Currently at 100 Snowmen on the Mumbai Testnet), these would be highly valuable assets for high frequency traders and traders trading large amounts of money.
Snowmen NFTs are transferrable and its holder has full control over it. He may hold it to enjoy commission free trading, sell it to high frequency trader or gift it to a friend.
Snowmen NFTs royalties from OpenSea also are transferred into the Snow Vault, furtherly adding liquidity to the platform.
