useAccountId()

Use it to fetch the connected account id.

INFO

You can connect an EVM account even if it's not a valid Hedera entity, but in this case, the result type will be slightly different as follows:

• Native: shardNum.realmNum.accountNum
• EVM: 0x${string}

TIP

Send some hbar to your EVM address (0x${string}) and the account will be automatically created on Hedera network.
