# MEV Shield
MEV bots actively monitor subnet alpha stake and unstake flows on Bittensor. If a bot anticipates your transaction, it can front-run it, resulting in worse execution and higher slippage.
To help protect against this, Talisman provides an "MEV Shield" option. When enabled, your staking operation is encrypted, reducing the likelihood of being front-run. You can enable MEV Shield by toggling it on - in the "Confirm Staking” page of a [subnet staking transaction](/talisman/bittensor-features/stake-tao-trade-dtao/stake-swap-on-dtao-subnets.md).
**Important:**
Even with MEV Shield enabled, if you only have one alpha position in an account, a shielded transaction can still indicate an incoming unstake. In this case, bots may act ahead of you regardless.
As an additional layer of protection, Talisman automatically applies a maximum slippage cap on every stake and unstake operation, limiting your exposure if the market moves against you during a transaction.
**Best practices:**
* Enable MEV Shield whenever possible.
* Split large stakes or unstakes into smaller chunks
* Avoid holding only one subnet position per account

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.talisman.xyz/talisman/bittensor-features/stake-tao-trade-dtao/mev-shield.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
