# Separate address for windowPoSt messages
WindowPoSt is the mechanism through which storage is verified in Filecoin. It requires miners to submit proofs for all sectors every 24h, which require sending messages to the chain.
Because many other mining related actions require sending messages to the chain, and not all of those are "high value", it may be desirable to use a separate account to send PoSt messages from. This allows for setting lower GasFeeCaps on the lower value messages without creating head-of-line blocking problems for the PoSt messages in congested chain conditions
To set this up, first create a new account, and send it some funds for gas fees:
```sh
lotus wallet new bls
t3defg...
lotus send t3defg... 100
```
Next add the control address
```sh
lotus-miner actor control set t3defg...
Add t3defg...
Pass --really-do-it to actually execute this action
```
Now actually set the addresses
```sh
lotus-miner actor control set --really-do-it t3defg...
Add t3defg...
Message CID: bafy2..
```
Wait for the message to land on chain
```sh
lotus state wait-msg bafy2..
...
Exit Code: 0
...
```
Check miner control address list to make sure the address was correctly setup
```sh
lotus-miner actor control list
name ID key use balance
owner t01111 t3abcd... other 300 FIL
worker t01111 t3abcd... other 300 FIL
control-0 t02222 t3defg... post 100 FIL
```
