Learnings on El Salvador Chivo app functionality so far:

- You can use the original $30 BTC to send off-chain, but you have to send it back and forth in Chivo 3-5 times
- You CAN send #Lightning to Chivo
- You CAN send Lightning FROM Chivo
- on-chain are NOT being batched

Native Segwit is being used.

The lightning invoices generated by Chivo contain the full legal name of the creator of the invoice. This to me seems like a privacy issue that should be dealt with.

Name is whited out but is in the "description" field.

According to this thread this morning, the Huawei verison of the app may have access to microphone and contact list. The iPhone and Android apps were slow to deploy this morning, maybe because of these concerns.

More clarity would be helpful.

Potential bug: When pasting in a lightning invoice which already has the number of sats required, the Chivo app asks the user to manually input the amount being sent. And when the it is inputted manually the payment throws error "No se pudo realizar esta operacion undefined."

Another bug: Chivo app appears to have a minimum send amount for both on-chain and lightning. We feel that this was created for on-chain BTC but was mistakenly applied to lightning as well.

Another bug: Chivo tends to scan LN QR codes correctly but when pasting in an LN invoice to the app it tends to bug out. This may be an format mismatch between Chivo and Bitrefill but I would suspect it is happening with other LN wallets as well.

Another bug: When sending on-chain BTC, Bitrefill asks the user to send a certain amount (.0001 BTC) and the user in Chivo inputs that number, but then afterwards Chivo takes the fee from that .0001 BTC and so Bitrefill receives less (.00095 BTC) than what was expected.

This is non-standard behavior with Bitcoin wallets. The fee should instead be deducted from the remaining balance in the Chivo user's app, not the amount being sent.
