Owners and Admins can open Team Wallet Settings on the Team page.
Maximum wallets per wallet type defaults to 5 and accepts whole numbers from 1 to 50. The limit applies independently to each member and each family, including enabled additional chains: five EVM plus five Solana plus five Bitcoin is valid when the limit is five.
Lowering the limit preserves all existing wallets. A member with seven EVM wallets under a new limit of five still sees 7 of 5; additions stay blocked until usage falls below the limit. Removing a wallet does not remove a personal mint wallet.
