Clone the source code from our git repository.
Build the node binary.
Copy and edit the configuration file.
Start the node to get its P2P public key.
Send the staking transaction from your Binance Chain wallet.
Enter the staking transaction into your node's configuration.
Start the node with the valid stake.
Note: Please make sure that you have the latest stable version of the Go language runtime installed. At the time of writing this is version 1.13.7.
Step 1. Clone the source code from our git repository: https://github.com/SwingbyProtocol/swapd-go
$ git clone https://github.com/SwingbyProtocol/swapd-go && cd swapd-go
Step 2. Build the node binary.
$ make build
Step 3. Copy and edit the configuration file.
$ cp -a ./configs/dist ./configs/prod$ nano ./configs/prod/config.toml
You should set the
moniker of your node to a name that is unique to your node, and check all of the other parameters in the file. Most importantly, you should check that the coins, endpoint URLs and
keygen_until match up with the rest of the nodes on the network that you are trying to join.
For now, there is no need to edit the staking TXID or address. Once you are ready, you can proceed to start the node.
Step 4. Start the node.
$ ./build/swapd --home ./configs/prod --p2p.port 12121
You should see some output similar to this:

This output indicates that your stake has not yet been established. We will do that next. Find this line in the output and copy the hex string of the P2P public key:
INFO 14:58:05.945 main The stored p2p public key is: 39cba7f80c263c3f872646e0b039bd4be0c031b50f11b6e1cb36e70a96dbefb5
In this example, the P2P public key is
39cba7f80c263c3f872646e0b039bd4be0c031b50f11b6e1cb36e70a96dbefb5. Copy this to your clipboard for later.
Step 5. Send the staking transaction from your Binance Chain wallet. Follow these steps:
Step 5.1. Create or unlock your Binance Chain wallet on the Binance Chain web wallet: https://binance.org/unlock.
You can unlock your wallet with any of the methods allowed, including Trust Wallet, Ledger device, Trezor device or Keystore file.
Step 5.2. Once you have unlocked your wallet, navigate to the Balances page to find your wallet address. This is the address where you will send your SWINGBY tokens to.
Step 5.3. Send the SWINGBY tokens that you would like to stake to your wallet address (as above).
Note: At the moment the required stake to run a full node is 100,000 SWINGBY. Sending more tokens than this will not give your node extra privileges nor generate extra income from swaps.
Step 5.4. Send the staking transaction.
The staking transaction is a self-send for the amount of tokens that you would like to stake. Click the Send button next your SWINGBY token balance row and enter the details.
Enter your own staking address in the To Address box. This is what is known as a self-send.
In the Memo box, you should paste your node's P2P public key that you copied in Step 4. After that, you should enter a comma (
,) followed by your BTC address to which you would like to receive reward payments.
Note: The BTC address for rewards should not be an exchange address as those addresses may change at any point in time. You should enter an address that you control the keys for such as from a Trust Wallet or Ledger device.
Click Next and finally confirm the transaction, which will send it to the blockchain.
Step 6. Enter the staking transaction into your node's configuration. Back in your terminal:
$ nano ./configs/prod/config.toml
Find the following lines in your configuration file:
[bnb]...stake_tx = ""stake_addr = ""reward_addr = ""[btc]...reward_addr = ""
stake_addr field you should enter the address that you are using to hold your stake. In this example the address is
stake_tx field you should add the TXID of your staking transaction. This is displayed in the Transactions page in the Binance Chain web wallet and is a long string like this:
reward_addr can be the same as your staking address or a new Binance Chain address that you would like to use for receiving swap rewards.
reward_addr should be the same as the one that you entered for the staking transaction memo in Step 5.4. In this example that address was
Step 7. Start your node.
Note: Stakes take 72 hours to mature. You should wait for this period of time before starting your node or else you will see the same failure message as in Step 4.
$ ./build/swapd --home ./configs/prod --p2p.port 12121
You should now see the node running with the valid stake.
