# FAQ

### Why is the account balance not refreshed after receiving the testnet tokens?

The balance display uses the toSignificant(6) method, that is, only the first six significant digits are retained. When the amount is relatively large, the fraction is not displayed, but it does not affect the transaction.

### Why does the rate of return change?

The annualized rate of return is estimated using the data at the current moment, such as the total lock-up volume or total transaction volume, block interval, unit block reward, etc. The unit block reward will generally not change, but the total locked position or total transaction volume is always changing, and the block interval is also dynamically changing, so the rate of return is floating.

### Why can't I see the testnet token in MetaMask after receiving KYI?

In this case, you can manually add a new custom token in MetaMask. The token contract address is right, and the token symbol is KYI. Just fill in and save it.

### When users using swap, adding liquidity or removing liquidity function, why do transactions fail?

During these three operations, you need to require the current transaction price. However, when the transaction is submitted to the chain, someone else may also submit the transaction and this move will affect the price. The deviation between the two prices is called a sliding point. You can improve the sliding point through the setting interface to solve this problem, but please pay attention to the risk. Increasing the sliding point may lead to a large difference between the actual transaction price and the price when the transaction is initiated.
