Edge Subscriber Connection

By connecting to DoubleZero I agree to the DoubleZero Terms of Use. Please note that the data is for your internal purposes only and may not be retransmitted (see Section 2(e)).

Already on the CLI subscription?

If you subscribed through the CLI (doublezero-solana shreds pay / escrow seats), use the CLI subscription page for those commands. That system is being decommissioned on August 30, 2026. New subscriptions follow this page.

Step 1: DoubleZero Setup

Complete Setup

Install the Solana CLI.

Follow the setup instructions to install and configure the DoubleZero client.

If you have previously set up DoubleZero, ensure you have the latest Doublezero-Solana CLI with sudo apt update && sudo apt install doublezero-solana

Configure the Firewall

Allow GRE, BGP, PIM, and shred traffic.

iptables:

sudo iptables -A OUTPUT -p gre -j ACCEPT
sudo iptables -A INPUT -i doublezero1 -s 169.254.0.0/16 -d 169.254.0.0/16 -p tcp --dport 179 -j ACCEPT
sudo iptables -A OUTPUT -o doublezero1 -s 169.254.0.0/16 -d 169.254.0.0/16 -p tcp --dport 179 -j ACCEPT
sudo iptables -A OUTPUT -o doublezero1 -p pim -j ACCEPT
sudo iptables -A INPUT -i doublezero1 -p udp --dport 7733 -j ACCEPT
sudo iptables -A INPUT -i doublezero0 -p udp --dport 44880 -j ACCEPT

UFW:

sudo ufw allow proto gre from any to any
sudo ufw allow in on doublezero1 from 169.254.0.0/16 to 169.254.0.0/16 port 179 proto tcp
sudo ufw allow out on doublezero1 from 169.254.0.0/16 to 169.254.0.0/16 port 179 proto tcp
sudo ufw allow out on doublezero1 proto pim from any to any
sudo ufw allow in on doublezero1 to any port 7733 proto udp
sudo ufw allow in on doublezero0 to any port 44880 proto udp

Step 2: Choose a metro

Identify the lowest-latency location from the machine that will receive shreds:

doublezero latency

Note the metro / city from the lowest-latency result. You will select that city on the application form. See the topology map for how metros are grouped.

Pricing

Seats are billed per month, per machine, in the metro you select:

Metros Price
Frankfurt, Amsterdam $1,500 / month
London, New York, Singapore, Tokyo $900 / month
All other locations $450 / month

Step 3: Submit Request

  1. Go to https://doublezero.xyz/edge/subscribe.
  2. Select Solana Shreds.
  3. Select the city (metro) you need. Use the table above and doublezero latency to choose.
  4. Finish the application form.

You will assign a DoubleZero ID (existing key, or generate a new one) to each feed request on the accounts page. The matching private key must be present on the machine that will receive shreds — do not assign a pubkey whose private key you cannot move to that host.

You pick a metro and a pubkey. You do not bind a public IP at application time. During the subscription you can move access between IPs within the chosen metros.

Our team reviews applications and contacts you in a timely manner (expect 2 business days).

Step 4: Connect after approval

After we contact you, you receive an invoice, and that invoice is paid, connect on each approved machine:

doublezero connect multicast --subscribe-feed solana-shreds-full

Access is enabled on your chosen start date, after access is provisioned you may check the tunnel status with:

doublezero status

Billing

Seats are charged monthly. Watch the seat expiration date.

You will be invoiced a few days before the seat expires. Not paying leads to removal of the seat.

Shred Addresses (IP vs Port)

Leader Shreds and high-stake Retransmit Shreds will arrive over port 7733, over the doublezero1 interface. The doublezero0 interface is for unicast traffic. Port 5765 is a heartbeat monitor from the shred publishers — this will not contain shreds.

For shred consumption, IP address identifies the multicast stream and port identifies the UDP service on that stream.
All shred streams below use UDP port 7733 on doublezero1.

You examine any multicast group's IPs with:

doublezero multicast group list

Leader Shreds

  • edge-solana-shreds: 233.84.178.1:7733

Root Shreds

  • edge-solana-root: 233.84.178.16:7733

Retransmit Shreds

  • edge-solana-retrans-eu: 233.84.178.12:7733
  • edge-solana-retrans-apac: 233.84.178.13:7733
  • edge-solana-retrans-amer: 233.84.178.14:7733

GRE Tunnel Header — XDP

Shred traffic delivered over the network is GRE-encapsulated. You may need to strip the GRE header before feeding data into your existing pipeline (e.g. an XDP-based deshredder).

Tools and Dashboards

Edge Scoreboard

Scoreboard benchmarks shred delivery speed across DoubleZero Edge and other providers, using slot-level data to compare performance in real time. Use this dashboard to see a view of Edge shreds win rates against other providers. You can view results for leader shreds only, in addition to full feed comparison. You can also drill down by region to see expected performance.

Edge Publishers

The "Publishing Shreds" metric at the top left of the dashboard shows the total percent of stake weight of all Solana validators publishing leader shreds on DoubleZero Edge. You can see details for each publisher on the network.

Edge Subscribers, Devices and Activity

You can search your Client IP on this page for subscribed seats and view status. You can also view available devices on the Devices page and all recent activity on the Activity page.

Data API Docs

For programmatic access to data endpoints, see the API documentation: https://data.doublezero.xyz/api/v1/docs.

Troubleshooting

If you run into an issue not covered here, please reach out over your existing channel before working around it. If you do not have a channel, please search Discord and open a ticket if required.

Ensure your Client is up to date:

Run: sudo apt update && sudo apt install doublezero-solana

Tunnel not coming up

  1. Verify the daemon is running: sudo systemctl status doublezerod
  2. Verify firewall rules are in place (GRE, BGP, PIM, shred traffic on doublezero1, port 44880 on doublezero0)
  3. Confirm the invoice for this seat is paid and the start date has passed
  4. Run doublezero connect multicast --subscribe-feed solana-shreds-full on the machine that holds the assigned private key
  5. Check your connection status: doublezero status

The DoubleZero ID used on the accounts page must match the key on this host.

Seat expired or removed

Seats are monthly. If the invoice sent before expiry is not paid, the seat is removed and the tunnel will not stay up.

"Multicast user already exists"

You already have an active subscription through a different path. Disconnect first with doublezero disconnect, then retry doublezero connect multicast --subscribe-feed solana-shreds-full.
