Chainstack is a multi-chain RPC provider with reasonable Solana support. If you've been on Chainstack for Ethereum work and are extending to Solana, the question is whether to keep them as your Solana provider or specialise.
This piece is a focused comparison: BoltTx vs Chainstack for Solana, what each does, when each fits.
At a Glance
| Dimension | BoltTx | Chainstack |
|---|---|---|
| Focus | Solana transaction sending | Multi-chain dedicated nodes |
| Anti-MEV | Native, default | Not Solana-native |
| SWQoS | Yes | Basic |
| Pricing | Tip-based | Tiered subscription |
| Best for | Solana trading, MEV-aware dApps | Multi-chain dApps, dedicated infra needs |
What Chainstack Is Good At
Multi-chain coverage. Solana plus most major chains. One provider for everything.
Dedicated nodes. They offer dedicated infrastructure for customers who need isolation. Useful for predictable performance.
Hybrid cloud / on-prem options. Some enterprise customers value this.
Reasonable Solana support. They cover standard methods adequately.
For multi-chain teams that value dedicated infrastructure, Chainstack is reasonable. Trade-off: not Solana-specifically optimised.
What BoltTx Is Built For
- Solana transaction sending
- Sub-second confirmation as a design floor
- Native Anti-MEV routing by default
- SWQoS-aware delivery
- Tip-based pricing
BoltTx specialises where Chainstack generalises.
Solana Comparison
Anti-MEV. BoltTx routes Anti-MEV by default. Chainstack doesn't have a Solana-native Anti-MEV product equivalent.
Solana-specific optimisation. Both providers run RPC fleets, but the depth of Solana-specific tuning differs. BoltTx has dedicated SWQoS infrastructure; latency profile under congestion is the practical differentiator.
Pricing model. Chainstack uses tiered subscription. BoltTx uses tip-on-landed. Different alignment with workload economics.
Self-serve onboarding. Both have it but different posture.
When to Pick Chainstack
- Multi-chain with dedicated infrastructure needs
- Enterprise environment with infrastructure isolation requirements
- Existing Chainstack relationship for other chains
- Solana usage is a smaller portion of overall traffic
When to Pick BoltTx
- Solana-focused workload
- Transaction sending heavy
- Anti-MEV protection by default
- Trading bot or dApp economics depend on landing rate

FAQ
Can I use Chainstack and BoltTx together? Yes. Multi-chain teams sometimes use Chainstack broadly + BoltTx for Solana sends specifically.
Is Chainstack faster than BoltTx for Solana? Depends on workload. Both can deliver sub-second under typical conditions. Specialisation matters most under congestion and at P95.
