About YieldBasis (YB)
YieldBasis is described as an on-chain liquidity protocol, which permits users to provide BTC as liquidity in an automated market maker (AMM) pool without facing impermanent loss (IL). This core feature aims to provide a robust platform for liquidity provision and efficient trading.
Mark Price Methodology
During the pre-market trading phase, mark prices will be calculated under a unique methodology to balance volatility and provide accurate pricing:
- The mark price during this phase derives from the average of the last 10 transaction prices sampled every second. If fewer than 21 transaction prices occur within the ten-second interval, it uses the average of the last 20 transaction prices.
Pre-Market Standard to Standard Transition
As the contract transitions into a standard perpetual futures contract, mark prices will gradually align with standard market calculations, while trading remains uninterrupted. Open orders and positions are secure throughout this transition.
Funding Rates Explained
The funding rates for this new contract consist of:
- Interest Rate: A flat fixed rate at 0.03% daily by default.
- Premium: Not applicable during the pre-market phase due to the lack of a premium index. A reduced funding rate of 0.005% will prevail during this period.
The funding rate will revert to standard practices post the pre-market trading period, adhering to established funding rate rules.
Trading Rules and Margin Tiers
The Binance Futures platform offers a structured approach to trading with distinct margin tiers based on leverage:
| Leverage | Position (Notional Value in USDT) | Maintenance Margin Rate |
