Gas wallet

One wallet pays every wallet’s network fees, so the others can be emptied to zero.

fee

The gas wallet signs each transaction as its fee payer, so the others can send every last lamport.

Why it helps

A wallet that pays its own fee can never quite reach zero: the fee has to come from somewhere. With a gas wallet, another wallet pays it, so Consolidate, Retire and Clean up can take a wallet down to exactly nothing.

How it pays

It pays the network fee, and any rent a move needs, for every other wallet in that move.
It goes last: it stays funded until every other wallet in the move is done.

Under the hood

Fee payer: Every Solana transaction names one account that pays its fee. Raven names the gas wallet, and it signs alongside the wallet that is moving money.
Rent too: When a move opens a coin account, the gas wallet puts up the rent, so the wallet being emptied does not need any SOL at all.
