Your unstaked RPC submission didn’t fit in the validator’s TPU window — the leader prioritized stake-weighted traffic and your QUIC handshake was dropped or queued past the slot.
Fixed by: SWQOSSolana · the unfun parts
Your tx failed.
It got dropped.
Most Solana teams are debugging the wrong layer. The transaction never reached the bank — it died at the RPC, the QUIC handshake, the scheduler, or the blockhash window. Blockspace is the inbound path validators actually use, sold as a service.
The four places a Solana tx diesFailed on-chain is the rare case.
Failed on-chain is the rare case.
Everything else is silent.
Every dropped-tx postmortem we run hits one of four chokepoints — none of them visible from your Sentry dashboard.
Once a tx reaches banking, SWQoS no longer helps — the scheduler is fee-based. Without a direct lane through the TPU adapter that reserves a bundle slot, you compete against every other tx in the pool.
Fixed by: TPU adapterYou decided to submit based on chain state that was 200ms old. By the time you signed, the bundle had already landed without you. The opportunity expired before the tx did.
Fixed by: ShredStreamShared shred feeds carry bursty traffic from other tenants. At peak hours that jitter shows up as variance in your shred arrival — not enough to break ShredStream, enough to break HFT-class arb.
Fixed by: Direct ShredsFour chokepoints. Four products that bypass them. Most teams debug the on-chain layer when the failure was actually before banking. Our stack exists because we hit each of these running Everstake’s validator — every product on this page started as a postmortem.

15,000 SOL.
Stake-weighted QoS is the protocol-level mechanism that gives staked traffic priority through the QUIC + banking pipeline. The threshold to access it as an operator sits around 15,000 SOL — a number that gates almost every independent searcher and mid-size DeFi protocol out of the priority lane.
Everstake has the stake. We resell it as a service — pubkey-scoped, no application form, no minimum SOL of your own. You whitelist the wallets that need priority; we route them through validator-grade QoS.

Four products.
One pain each.
Every product on this page exists because we ran into the same pain operating Everstake’s validator. They aren’t features — they’re the answers.

ShredStream
Stream Solana shreds before slot confirmation
Receive raw Solana shreds before slot confirmation. Frankfurt #2 globally — the kind of latency profile node operators rarely sell. Seven regions live today.

Direct Shreds
Dedicated IP, your bandwidth alone
For workloads that can’t tolerate shared-tier jitter — a dedicated IP-isolated shred feed. Your bandwidth, your IP, zero co-tenant variance. Different product from Ultra ShredStream, different need.

When your unstaked path is deprioritized →
SWQOS
Stake-weighted priority lane
Stake-weighted priority into the validator’s TPU — the lane unstaked RPCs queue behind. Pubkey-scoped — only the wallets you whitelist get the boost. No 15k SOL minimum of your own.

Relayer + TPU adapter
MEV mempool + direct TPU submission
Two components, sold separately or together. Relayer is the MEV mempool — searchers submit bundles, auction runs, winners queue. TPU adapter ships winning bundles direct to the validator’s TPU — ~250ms priority window per leader, pay only if your bundle is profitable.

The rest of the stack is catching up.
ShredStream is live in Frankfurt, Amsterdam, New York, Tokyo, London, Dublin, and Singapore — three continents, seven POPs. SWQOS is live in all seven; Direct Shreds and Relayer + TPU are expanding region-by-region from Frankfurt. We don’t claim coverage we haven’t shipped.

FAQ
Blockspace is Everstake’s Solana MEV stack — sub-10ms shred delivery (ShredStream), dedicated shred feeds (Direct Shreds), stake-weighted priority transaction routing (SWQOS), and bundle-aware relay (Relayer/TPU) — built and operated by Everstake.
Frankfurt (FRA) is our flagship region — ranked #2 globally in shred latency benchmarks. ShredStream and Direct Shreds ship from Tier-1 carrier points; SWQOS routes through Everstake’s Solana validator stake.
Enterprise contracts include dedicated infrastructure, on-call rotation, and a signed SLA with service credits. Self-serve tiers run on best-effort. Contact sales for an SLA addendum.
