Send and Receive Tokens with the Openos CLI
This page describes how to receive and send BTG tokens using the command line tools with a command line wallet such as a paper wallet, a file system wallet, or a hardware wallet. Before you begin, make sure you have created a wallet and have access to its address (pubkey) and the signing keypair. Check out our conventions for entering keypairs for different wallet types.
Testing your Wallet
Before sharing your public key with others, you may want to first ensure the key is valid and that you indeed hold the corresponding private key.
In this example, we will create a second wallet in addition to your first wallet, and then transfer some tokens to it. This will confirm that you can send and receive tokens on your wallet type of choice.
This test example uses our Developer Testnet, called devnet. Tokens issued on devnet have no value, so don't worry if you lose them.
Airdrop some tokens to get started
First, airdrop yourself some play tokens on the devnet.
openos airdrop 1 <RECIPIENT_ACCOUNT_ADDRESS> --url https://api.devnet.openverse.network/
where you replace the text <RECIPIENT_ACCOUNT_ADDRESS> with your base58-encoded
public key/wallet address.
A response with the signature of the transaction will be returned. If the balance of the address does not change by the expected amount, run the following command for more information on what potentially went wrong:
openos confirm -v <TRANSACTION_SIGNATURE>
Check your balance
Confirm the airdrop was successful by checking the account's balance.
It should output 1 BTG:
openos balance <ACCOUNT_ADDRESS> --url https://api.devnet.openverse.network/
Create a second wallet address
We will need a new address to receive our tokens. Create a second keypair and record its pubkey:
openos-keygen new --no-passphrase --no-outfile
The output will contain the address after the text pubkey:. Copy the
address. We will use it in the next step.
pubkey: GKvqsuNcnwWqPzzuhLmGi4rzzh55FhJtGizkhHaEJqiV
You can also create a second (or more) wallet of any type: paper, file system, or hardware.
Transfer tokens from your first wallet to the second address
Next, prove that you own the airdropped tokens by transferring them. The Openos cluster will only accept the transfer if you sign the transaction with the private keypair corresponding to the sender's public key in the transaction.
openos transfer --from <KEYPAIR> <RECIPIENT_ACCOUNT_ADDRESS> 0.5 --allow-unfunded-recipient --url https://api.devnet.openverse.network/ --fee-payer <KEYPAIR>
where you replace <KEYPAIR> with the path to a keypair in your first wallet,
and replace <RECIPIENT_ACCOUNT_ADDRESS> with the address of your second
wallet.
Confirm the updated balances with openos balance:
openos balance <ACCOUNT_ADDRESS> --url http://api.devnet.openverse.network/
where <ACCOUNT_ADDRESS> is either the public key from your keypair or the
recipient's public key.

Receive Tokens
To receive tokens, you will need an address for others to send tokens to. In Openos, the wallet address is the public key of a keypair. There are a variety of techniques for generating keypairs. The method you choose will depend on how you choose to store keypairs. Keypairs are stored in wallets. Before receiving tokens, you will need to create a wallet. Once completed, you should have a public key for each keypair you generated. The public key is a long string of base58 characters. Its length varies from 32 to 44 characters.
Send Tokens
If you already hold BTG and want to send tokens to someone, you will need
a path to your keypair, their base58-encoded public key, and a number of
tokens to transfer. Once you have that collected, you can transfer tokens
with the openos transfer command:
openos transfer --from <KEYPAIR> <RECIPIENT_ACCOUNT_ADDRESS> <AMOUNT> --fee-payer <KEYPAIR>
Confirm the updated balances with openos balance:
openos balance <ACCOUNT_ADDRESS>
