Register the Node On-Chain

Run these commands on your computer, not on the server. They use the owner key from Prepare Your Computer.

You need id and public_key from Configure the Node. public_key is the operator key; the steps call it <OPERATOR_PUBLIC_KEY>.

tip

If a command fails with 429 or rate limits exceeded, wait a few seconds and run it again.

1. Fund the operator key

The operator key pays the node's fees. Get devnet SOL for <OPERATOR_PUBLIC_KEY> from the Solana faucet, for example 0.1 SOL. Check it:

sentinel-dvpn wallet balance --owner <OPERATOR_PUBLIC_KEY>

2. Open the node

Use the same country, port, and prices as init.

sentinel-dvpn node open-node \
  --node-id <ID_FROM_INIT> \
  --country <COUNTRY_CODE> \
  --uri "https://<SERVER_IP>:8443" \
  --protocols <PROTOCOL_NUMBER> \
  --bond 10000000 \
  --prices.channel-price-per-gb 50000000 \
  --prices.channel-price-per-hour 50000000 \
  --prices.lease-price-per-hour 50000000

<PROTOCOL_NUMBER> is the number for your protocol:

Protocol	--protocols
wireguard	1
v2ray	2
openvpn	4
amneziawg	8
xray	16
hysteria2	32

--bond is in base units (10000000 = 10 tDVPN). It must be at least min_node_bond from sentinel-dvpn program params.

3. Find the node address

sentinel-dvpn node search --owner <OWNER_PUBLIC_KEY>

Copy the address of the entry whose node_id matches your id. The next steps call it <NODE_ADDRESS>.

4. Let the operator key run the node

sentinel-dvpn grant open-grant \
  --grantee <OPERATOR_PUBLIC_KEY> \
  --target <NODE_ADDRESS> \
  --permissions 6 \
  --never-expires \
  --allowance 0

6 lets the server update and list the node. --allowance 0 means it can't spend your tokens.

5. Check

sentinel-dvpn node show <NODE_ADDRESS>

Check the uri, protocols, and prices. The node lists itself for clients when you start it.

Next: start the node.
