The “Ten Commandments” of Solon (as recorded in Diogenes Laertius’ “Lives of Eminent Philosophers”, 1.60), are as follows:

1. Trust good character more than promises.
2. Do not speak falsely.
3. Do good things.
4. Do not be hasty in making friends, but do not abandon them once made.
5. Learn to obey before you command.
6. When giving advice, do not recommend what is most pleasing, but what is most useful.
7. Make reason your supreme commander.
8. Do not associate with people who do bad things.
9. Honor the gods.
10. Have regard for your parents.

Hat-tip to Richard Carrier, from whom I learned about this list of “commandments”.
