TrustVault generates Segwit transactions and will allow sending to native Segwit addresses.
However, at this time we do not generated native Segwit addresses in your TrustVault wallet.
Sending FROM a TrustVault wallet you can send to all three types of addresses:
Legacy: starts with a 1
Segwit: starts with a 3
Native Segwit: starts with a bc1
Sending TO a TrustVault wallet you can only generate a receive address in the Segwit format (starts with a 3)
