Most projects put 12 month or greater lockups on tokens (which I'd recommend for both vesting considerations and protections for the protocol against dumping).
The standard YC advisor templates are fairly easy to translate to token-based compensation and are battle tested.
Just like advisor compensation in stock, both the protocol and the advisor should weight the advisory scope, how early the project is, and determine fair %s from there.
Generally what percentage of the total supply do you get?
Do you have a lockup period?
Are these primarily defi protocols?
Can you disclose what projects you worked on?
