Sponsorship
Sponsor an account, offering to pay for all transaction fees for that account.
You should only sponsor an account you trust, and/or have a legally binding agreement with. A sponsored account holder can easily drain your account through spam transactions. If the account holder is running a node, he/she can claim part of the spend tokens as mining reward. Limit the amount of tokens on the sponsoring account, adding funds when necessary.
See transaction fees with sponsored accounts for more info.
