# Coin Address Table

We have modified the default behaviour for accounts that have a coin address associated with them. Instead of a single column in the accounts table, all coin addresses are now stored in a `coin_addresses` table. It will allow multipool instances to access each coins coin address separately as defined by `$config['currency']`. With some modifications, running a multipool should have become a lot easier now. Would be great if someone could confirm this!

Ensure you run the upgrade script supplied to migrated all users coin_address column over to the new coin address table! If you have issue migrating, telling them to just update their account will also work.
