Recently I open extension of nami walle to transfer my funds but for some reasons when I transfer ADA Always says transaction failed I do know the password but previous when I send ADA to someone I just put addr and send by typing pin password now it’s not working and I don’t have access to recovery so what’s the solution?
First: Not having access to recovery is not good! You are setting yourself up for completely losing your funds with that. If you don’t have the seed phrase anymore, transfer to a new wallet as soon as possible.
There does not seem to be a general problem with Nami right now. Just sent something successfully.
Does it give you a more detailed error message?
Do you have a custom node in your network settings? Deactivate it!
Is it possible that you just don’t have enough ADA in that wallet? If there are NFTs/tokens in the wallet, some ADA have to stay if you do not send them out as well.
