Nah, walls are safe from corruption. Corruption spreads through blocks, not walls. So you can build your base without fear!
Corruption proof walls? Yes - Terraria's got you covered. Walls are immune to corruption. Just make sure the rest of your base is protected!
Actually, corruption doesn't spread through walls, but don't forget it can jump over small gaps in blocks. So while your walls are safe, the blocks they're standing on might not be if you're not careful.
