FLIP #281

It is possible to also use a resource we call the Depositor for this in case you weren't aware:
https://github.com/Flowtyio/lost-and-found/blob/main/contracts/LostAndFound.cdc#L506

You can find sample transactions for its use here:
https://github.com/Flowtyio/lost-and-found/tree/main/transactions/depositor

The issue I've found with FeeEstimator is that every account on Flow is different. What works the account that does fee estimation might be too little to for another account that intends to use that estimation

Despositor is great for more advanced use cases but we're not looking to sponsor storage fees for now. We like to show the total cost of transfer to the user for payment.

Can you elaborate on whats the best way to estimate the total cost of interaction (deposit)? Can we use https://github.com/Flowtyio/lost-and-found/blob/main/scripts/lost-and-found/estimate_deposit_nft.cdc?

Probably worth mentioning here that the minimum cost for a new account is likely to increase (I think?) Which would drastically increase the minimum needed to send things using this method.

I recall doing benchmarks a very long time ago and found that you could send a few thousand NFTs (very basic ones) for 1 FLOW of storage, it should be the cheapest option by far

Yeah, the storage balance is the deal breaker for this approach. Added a comment af2cddc

We have a basic integration working live on port.flow.com now
