Subglow vs BullX
Two approaches to Solana copy trading. BullX wraps a Telegram UX around shared public RPC. Subglow runs on its own private Yellowstone gRPC with non-custodial wallets. Here's the honest comparison.

Latency: private gRPC vs shared public RPC
Every copy-trade bot on Solana lives or dies on how quickly it can see a target wallet's transaction and land its mirror tx in the same or adjacent slot. That time budget — from on-chain confirmation to your fill — is the difference between copying a 50x move at entry price and catching it after a 40% markup.
BullX, like most Solana copy-trade tools, consumes public RPC (generally Helius, QuickNode, or Solana Labs). Public RPC endpoints batch subscriptions across tens of thousands of users, which introduces 500–2000ms of delay between slot confirmation and when your client sees the event. Even on their fastest plans, public RPC providers do not prioritize individual customers in a way that matters for sub-second trading.
Subglow ships its own Yellowstone gRPC cluster — the exact same infrastructure we sell to institutional customers for their own trading bots. Our copy-trade executor consumes this stream directly, so wallet transactions surface within 30–80ms of slot confirmation. Combine that with Jito bundle submission (which gives us atomic same-slot inclusion) and the end-to-end wire from on-chain confirmation to our confirmed fill is typically 200–400ms.
Custody: who holds your SOL while it sits idle?
The default BullX experience is custodial: you deposit SOL to a wallet controlled by BullX, and the bot trades from that pool. You have an account balance, but you don't own the underlying on-chain wallet. If BullX is ever compromised, subpoenaed, or exit scams, those funds are gone. BullX has recently added self-custody options, but they are not the default path and most users remain in the custodial flow.
Subglow is non-custodial by design. When you open an account we generate a fresh Solana keypair for you. The encrypted key sits on our infrastructure for the executor to sign with, but it's exportable to your personal wallet in one click. If Subglow goes offline tomorrow, you sweep the wallet and your funds are safe. This is the same mental model as Phantom or Solflare, not a CEX.
Fees: 0.2% flat vs 1% + spread
BullX charges approximately 1% per copied swap, plus whatever spread they take on routing. Their Pro tier adds a monthly subscription on top of that. For active copy traders, those fees compound fast — 10 trades per day means ~10% of your capital is paid in fees per month before you even count slippage.
Subglow charges 0.2% flat per trade, paid transparently to our on-chain treasury in the same signed transaction as the swap. There's no subscription, no routing spread, and no hidden markup. The only other cost is the Jito tip (dynamic, typically 0.001–0.005 SOL) and Solana's priority fee (a few thousand lamports) — both of which you can see in your Solscan trace.
When BullX is still the right choice
We're not going to pretend BullX doesn't have advantages. If you live in Telegram and prefer not to leave your chat app to trade, BullX's bot flow is extremely polished. If you need features that go beyond copy trading — advanced limit orders, TWAP schedules, or their marketplace of sniper presets — BullX currently has a wider product surface.
Subglow is laser-focused on non-custodial, low-latency copy trading. Nothing else. That's a feature for us: fewer moving parts means less attack surface, tighter latency budgets, and a fee model that doesn't need to support sprawling infrastructure. If you want a Swiss-army-knife Telegram trading suite, BullX is a better fit. If you want the fastest, cheapest, safest copy trader, Subglow is.
For execution latency, fees, and custody, Subglow wins on every dimension that directly affects your realized PnL. Private gRPC beats shared public RPC, 0.2% flat beats 1% plus spread, and an exportable key beats a custodial pool.
For UX and feature breadth, BullX has a richer Telegram experience and more adjacent tools. If that's your priority, keep using BullX and run Subglow for your high-priority copy targets where the latency and fee difference matters most.
