**5. Check Snipes result onchain and enjoy the profit**

If the Open Trade / LP Transaction arrives to Alfred RPC - user bribe will be landed to Alfred Proxy Address.&#x20;

Bribe for Base is calculated in the following way:&#x20;

* *Bribe = User Extra Priority Gwei \* 150 000 Gas Limit*&#x20;

Example. If user put 10 gwei priority, the bribe will be the following:

* *10 Gwei \* 150 000 Gas Limit = 0.0015 ETH*
