Announcing the Spindl on-chain referrals product
I remember when online poker was big for a while, indeed created a pretty big online economy, around referrals earning % of lifetime value. Easier to trace in Web3, to be sure -- and to put into a contract.
Also interesting to pay referrers in a native token, or any token. Can see that alone much better for incentives, and much easier to justify for a growing project than hard USDC.
