# ERC20 Vault Mechanism | ERC20 保险库机制

The ERC20 platform provides an advanced vault infrastructure that we will leverage to strengthen the token economy. Each buy or sell transaction of $YWAI on a DEX will incur a small fee (e.g., 5%). This fee will be collected in a smart vault. Revenue from this fee will be automatically used for:

* **Buyback & Burn:** A portion of the funds will be used to buy back $YWAI from the market and burn them, reducing the circulating supply and potentially increasing the token's value in the long term.
* **Liquidity Injection:** Another portion will be added to the liquidity pool to ensure healthy market depth and reduce slippage for traders.
