RE: What does onboarding 10,000 active users look like?

It's just not worth 460k to do this. I am not sure your exact mechanism of how it operates, but we already have the beneficiaries tag, L2 through hive-engine and soon csv, and if you are merely porting a private key to multiple wallets, the source code is already public domain.
Granted Trying to code a wallet or wallet functions from scratch may be niche, but once you learn the recipe it is rinse and repeat. And most wallet devs don't go even build from scratch because of the vulnerabilities-they modify what has already been tried and tested so the niche knowledge isn't required anyways. I just don't see the value, I just see that the chain is being screwed out of half a million dollars. It may be more fruitful than "valueplan", but we are still overpaying by at least a factor of 10.

We also have to examine the cost to onboard a new user. What are you really projective porting inleo to new chain users will return in active users? I hope it would be are more than this 10000 user figure on your past proposal, as that would be $46 per user. I don't really see that as being effective, and while it might increase the traffic on hive, the rewards being paid out in different currencies would have a liquidation effect on the hive rewards.

The burden is on you to justify the proposed expense.
