The Jito ShredStream alternative: AllenHark Jito Shreds
Jito switched off ShredStream on September 5, 2026. AllenHark is currently the only Jito Shreds provider, and Jito Shreds is the live, maintained replacement: keep your keypair and your proxy workflow, register your pubkey, and point --block-engine-url at us. Nothing else in your pipeline changes.
What stopped on September 5, 2026
Jito posted its ShredStream deprecation notice in early July 2026 and pointed users to DoubleZero Edge. Since September 5, Jito's infrastructure no longer authenticates proxies or sends shreds, so its own shredstream-proxy has nothing to connect to. The notice reads:
“We are beginning the process of deprecating Jito ShredStream. The service will be completely shut down in 60 days (September 5, 2026), meaning you won’t have access to Jito ShredStream at that time.”
“To ensure uninterrupted access to Solana shreds, we highly recommend transitioning to DoubleZero Edge before the shutdown date.”
From Jito's ShredStream page, checked 28 October 2026. It links DoubleZero's transition guide for the move.
Shreds themselves didn't go away, only Jito's delivery of them, so moving is an endpoint change, not a rebuild. We maintain a fork of the proxy without the shutdown switch, and run the gateway it talks to. Your socket and deshredding code stay exactly as they are.
Jito Shreds has its own product page, the docs have every command, and the migration guide walks through the whole cutover.

Migrate in four steps
Install the AllenHark proxy fork
Jito's upstream shredstream-proxy refuses to start past the shutdown date. Clone and build allenhark-shredstream-proxy, a fork of Jito's shredstream-proxy that we maintain without the shutdown switch. Same CLI flags, same auth flow: challenge, JWT and heartbeat.
Register your keypair's pubkey
Sign in to the AllenHark console, open Jito Shreds, and submit your existing keypair's public key for whitelisting, never the private key. You keep the keypair your shredstream-proxy already authenticates with; there is no new key to generate. Then start the 24-hour free trial, or subscribe.
Point --block-engine-url at AllenHark
Set your proxy's --block-engine-url to https://fra.jito.allenhark.network and --desired-regions to frankfurt: the region is accepted but not used for routing, as the gateway serves from Frankfurt. --auth-keypair and --dest-ip-ports stay as they are, and your socket and deshredding code don't change.
Confirm shreds are flowing
The proxy's log shows the auth handshake (challenge signed, JWT issued) and its heartbeat, packets arrive on your --dest-ip-ports, and the console shows your subscription active and connected. Jito's own proxy stopped working on September 5, 2026; ours keeps running.

Frequently asked questions
Is there a Jito ShredStream alternative?
Yes. AllenHark Jito Shreds is a live, maintained drop-in replacement for Jito's ShredStream feed, which shut down on September 5, 2026. You keep the shredstream-proxy workflow and your keypair: register your pubkey, repoint --block-engine-url at https://fra.jito.allenhark.network, and nothing else in your pipeline changes.
When did Jito ShredStream shut down?
Jito discontinued ShredStream on September 5, 2026, after a deprecation notice in early July 2026 that recommends DoubleZero Edge. Since then Jito's own shredstream-proxy no longer authenticates or receives shreds, so you need a maintained alternative.
How do I migrate off Jito ShredStream?
Build the AllenHark shredstream-proxy fork, register your keypair's pubkey in the AllenHark console, set --block-engine-url to https://fra.jito.allenhark.network, and confirm shreds are arriving on your --dest-ip-ports. The docs have every command and flag.
I don't want to change my socket code — can I keep running shredstream-proxy?
Yes. Keep the proxy workflow and your keypair, register the keypair's pubkey in the console to be whitelisted, and set --block-engine-url to https://fra.jito.allenhark.network. Set --desired-regions to frankfurt; it is not used for routing. Shreds arrive on the same --dest-ip-ports as before.
Do I still need a keypair or proxy like Jito's ShredStream?
Yes, and that is the point: AllenHark Jito Shreds is a drop-in replacement, not a re-architecture. You run shredstream-proxy (our maintained fork) with your existing keypair; only the --block-engine-url changes. Whitelisting is by pubkey: register the public key, never the private key.
How do I know shreds are flowing?
The proxy's log shows a successful auth handshake (challenge signed, JWT issued) and an established heartbeat, packets arrive on your --dest-ip-ports, and the console shows your Jito Shreds subscription as active and connected. If nothing arrives, check that the registered pubkey matches the --auth-keypair the proxy runs with.
Which regions does AllenHark Jito Shreds serve?
Frankfurt, through one gateway at https://fra.jito.allenhark.network. Set --desired-regions to frankfurt. Additional regions will be announced as they come online.
How much does AllenHark Jito Shreds cost?
$50 a month, pubkey-whitelisted, billed monthly: one pubkey per subscription and one subscription per account. The gateway runs in Frankfurt. A 24-hour free trial lets you check the migration end to end before you pay.
Jito ShredStream was free — why pay for shreds now?
Jito's free feed ended on September 5, 2026, so it is no longer an option. Jito's recommended path, DoubleZero Edge, is a paid subscription too, sold per seat. AllenHark Jito Shreds is $50 a month, pubkey-whitelisted, with a 24-hour free trial so you can see shreds arriving before you pay.
How does AllenHark compare to DoubleZero Edge, Jito's recommended path?
DoubleZero Edge delivers raw shreds by multicast over DoubleZero's own network: you install the DoubleZero client, connect to one of its devices and subscribe to a seat, billed monthly per machine and priced by metro. AllenHark Jito Shreds keeps Jito's proxy protocol, so if you already run shredstream-proxy you change one URL instead of your setup, for one flat monthly price.
