How transactions reach the leader, how shreds and streams move, and how we run the machines. Written by the people who build them.
Jito's ShredStream feed shuts down September 5, 2026. Here's the full migration guide to AllenHark Jito Shreds — a drop-in replacement that keeps your keypair, your shredstream-proxy binary, and your existing pipeline intact.
Step-by-step ShredStream setup: choose between shared gRPC and direct UDP, connect with Rust or TypeScript, parse entries, and avoid the common pitfalls — with real endpoints.
What Jito bundles are, how the Block Engine and tip auction work, and how to submit atomic Solana transactions over HTTPS, QUIC, or WebSocket with AllenHark Relay — with code examples.
A technical walkthrough of how Soltrace mirrors Solana traders: watching programs not wallets, attributing swaps to their signer, fanning out to your vault, and keeper-signed execution across Raydium, Orca, Meteora, Pump.fun and PumpSwap.
Soltrace is now live on Solana mainnet: mirror the on-chain trades of wallets you choose while your funds stay in your own PDA vault. Non-custodial, red-team tested, and built into the AllenHark Console.
A transparent breakdown of Soltrace pricing: a flat 0.85% per trade on every plan with no profit split or revenue share, four tiers from Free to Elite, RPC vs relay submission by tier, and accepted payment in USDC and USDT.
Most Solana copy-trading bots take custody of your funds. Soltrace doesn't. Here's what non-custodial really means — your own PDA vault, owner-only withdrawal, and a keeper that can trade but never withdraw.
An evaluation of the white-label Solana validator landscape in 2026 — Figment, Chorus One, Blockdaemon, AllenHark — with criteria, pros and cons, and how to pick for exchanges, wallets, funds, and LST issuers.
Why your QUIC client throws 'aborted by peer: the cryptographic handshake failed: error 120: peer doesn't support any known protocol' when connecting to AllenHark Relay — and the exact Rust + Python code that fixes it.

What to evaluate in a managed Solana validator provider's security posture — key management, slashing protection, sanctions screening, audit trails, change management, hardware isolation, and incident response.
Operator guide for launching a branded LST on Solana backed by a dedicated validator. Covers SPL stake pools, Sanctum integration, mint authority, fee parameters, MEV-tip distribution, and the full launch timeline.
Five-step playbook for moving a self-hosted Solana validator to a managed provider without missing a vote. Vote-key handover, slashing-protection bookkeeping, warm catchup, hot-standby cutover, and post-migration validation.
AllenHark Relay now supports persistent wss:// connections — open one socket, stream as many transactions or bundles as you want. Less handshake overhead, lower latency, browser-native, and bundle-aware.
Running a Solana validator is a full-time job. AllenHark's managed validator service lets you earn staking rewards under your own brand with zero operational burden.
AllenHark Relay now spans 4 regions with QUIC, WebSocket and HTTPS endpoints, private delivery to the current leader, and Jito bundles. Here's what it does and how to use it.
A practical breakdown of every method for landing Solana transactions — from public RPCs to direct TPU submission — and why sender-agnostic, leader-aware routing matters in 2026.

An introduction to Slipstream — a leader-proximity-aware transaction relay that picks the sender closest to the current leader for each of your Solana transactions.
A complete guide to the February 2026 PumpFun bonding curve program upgrade that broke buy/sell transactions. Covers the new bonding_curve_v2 PDA requirement, the cashback_enabled flag, and correct account layouts.

Priority fees aren't enough. Distance and public-internet routing decide when your transaction reaches the leader, and running near the leaders is the fix.
Clarifying the difference between 'Reading' and 'Writing' on Solana. Why gRPC and Shreds help you see the chain early but cannot send transactions themselves.
Why public RPCs and standard propagation land trades a slot or more late, and how a private relay to the current leader closes the gap.
