There's no mint to mint transfers in any way. Mints don't communicate with other mints, ever. Mints don't care if another mints tokens are valid or not.

Mints only do two things. They mint tokens after receiving a lightning payment. They melt tokens after paying a lightning invoice. The mint doesn't care where the lightning invoice has come from. And the mint isn't actually paying the invoice, the lightning node providing the collateral does. The mint only gets confirmation that the invoice has been paid, then it melts the tokens.

It doesn't matter to the mint if the lightning invoice you give it to pay is from bitrefill or another mint. It's just a lightning invoice, nothing more.

It also doesn't matter to the mint what you do with the tokens, it doesn't track them. The mint only knows if they've been redeemed, not who redeemed them.

When you redeem an ecash token, the mint just confirms that the tokens are valid, it doesn't know who they came from. Whereas a lightning payment, always discloses the node ID where the payment came from.
