Staked Solana RPC with SWQoS – TPU TX sender

SWQoS is Solana's mechanism that gives high-stake validators priority access to the leader's TPU (Transaction Processing Unit). Validators with more stake get proportionally more bandwidth to submit transactions. This prevents network spam and ensures that staked connections land transactions even during congestion, while unstaked public RPC nodes get throttled or dropped.

During congestion (NFT mints, meme coin launches, liquidation cascades), Solana's SWQoS prioritizes transactions from staked validators. If you're using a public RPC or unstaked endpoint, your transactions compete for limited bandwidth and often fail. Staked RPC endpoints route your transactions through high-stake validator connections, bypassing the congestion that blocks regular users.

Our Staked RPC forwards your transactions through validators with significant stake, inheriting their SWQoS priority. We track the leader schedule in real-time and route directly to the current and next leaders via their TPU. Combined with sub-millisecond latency from our Frankfurt, Amsterdam, and NYC datacenters, this achieves 90%+ landing rates even in competitive slots where public endpoints fail completely.

Regular RPC nodes are unstaked and have no priority access to leaders. During congestion, transactions queue behind staked traffic and often timeout. Staked RPC uses peering agreements with high-stake validators to access the prioritized SWQoS path. Your transactions skip the public queue and land in slots where unstaked submissions fail. Essential for MEV, sniping, and trading bots.

We use pay-per-transaction pricing with transparent tip requirements. No monthly fees, no auctions, no complexity. You include a small tip (priority fee) in your transaction, and we handle the routing. You only pay for transactions that actually land. Contact us for current tip requirements based on your volume.

Any operation where transaction timing is critical: MEV arbitrage (landing in same slot as target), sniper bots (first execution on new tokens), liquidation bots (beating competition to positions), trading bots (reliable fills in volatile markets), and NFT minting (securing allocation during launches). If milliseconds matter, you need SWQoS.

Yes. Send us your signed transaction via our API endpoint. We handle leader tracking, TPU routing, and priority submission. Works with any Solana SDK (Rust, TypeScript, Python). No code changes needed beyond pointing your sendTransaction calls to our staked endpoint and including the required tip instruction.

Both solve the same problem (landing transactions in competitive slots) but differently. Jito bundles use MEV auctions where you bid against others for block inclusion, with variable costs and no guarantee of winning. Our Staked RPC uses direct SWQoS priority via validator peering: fixed per-transaction pricing, no auction complexity, predictable costs. For simple "land this fast" use cases, Staked RPC is simpler and more cost-effective. For complex MEV strategies requiring atomic bundle execution or specific transaction ordering, Jito may be more appropriate. Many teams use both depending on the operation.
