An autonomous yield and liquidity generating mechanism is SAFEMARS.
Each transaction is subject to a 4% tax under SAFEMARS. Uses for this tax include: A quick and gas-free 2% distribution is made to SAFEMARS holders. Holders will simply see that they have additional SAFEMARS tokens in their wallet; there is no need to farm or claim. By automatically pairing 2% with BNB and growing liquidity, the SAFEMARS price floor is continuously raised.
According to SAFEMARS, the SAFEMARS protocol would automatically distribute rewards to holders for each transaction and permanently lock the liquidity by burning BNB/SAFEMARS LP tokens. The firm says that by making these daily burns transparent and trackable on the blockchain, the currency is "unruggable."
