EXIT will likely be available through a token swap process, details are TBD.
Minting, burning and monetary policy are still in the research phase. EXIT issuance will likely occur in several phases.
Not through any centralized exchanges, but EXIT will be available to swap on decentralized exchanges (DEXs) as the market determines the value of this.
The amount of soft ETH in the reward contract provides the backing to support a stable valuation. For every $1 USD of EXIT that is minted, $2 USD worth of soft ETH is also added. The provides a large cushion to support fluctuating ETH prices.
Soft Ether provides a virtual overcollateralization method for creating the Stable EXIT coin. Since it is always at a 2:1 ratio (there is 200% of soft Ether relative to EXIT in the reward contract) the price of Ether can rise or fall dramatically without impacting the price of EXIT. When the price does rise or fall, the rebalancing feature maintains the ratio.
On an daily (configurable) basis, the contract calls an oracle which provides the current ETH price, and this price is inherited by soft ETH. If the price has dropped, more soft ETH is minted to match the 2:1 ratio. If the price has increased, the excess soft ETH is burned to maintain the same ratio.
EXIT is an algorithmically derived commodity, it's value and usage will be determined by the marketplace.
As an ERC20 token, EXIT can be traded on DEXs, sent to wallets, used as a means of trade, and accommodate any other ERC20 functionality.
