Ankr is one of the larger multi-chain RPC providers, supporting dozens of chains including Solana. If you're doing cross-chain work, Ankr is a name you'll see. For Solana specifically, the question is whether multi-chain coverage or chain-specific specialisation matters more for your use case.
This piece covers BoltTx vs Ankr for Solana — when each fits, when each doesn't.
At a Glance
| Dimension | BoltTx | Ankr |
|---|---|---|
| Focus | Solana transaction sending | Multi-chain general-purpose RPC |
| Anti-MEV | Native, default | Not Solana-native |
| SWQoS | Yes | Yes (basic) |
| Pricing | Tip-based | Per-credit / monthly tiers |
| Best for | Solana trading, MEV protection | Multi-chain dApps, broad coverage needs |
What Ankr Is Good At
Multi-chain breadth. Dozens of chains supported. If you're building cross-chain, the operational simplicity of one provider matters.
Reasonable pricing for general use. Their tiers cover small-to-mid-scale workloads at modest cost.
Standard RPC support. They cover the standard JSON-RPC methods adequately across their chains.
For multi-chain dApps where Solana is one of many supported chains, Ankr is a defensible choice. Trade-off: not chain-specifically optimised.
What BoltTx Is Built For
- Solana-focused transaction sending
- Sub-second confirmation as a design floor
- Native Anti-MEV routing by default
- SWQoS-aware delivery
- Tip-based pricing
BoltTx is narrower than Ankr by design.
Solana Send Comparison
For Solana write traffic specifically:
Anti-MEV. BoltTx routes Anti-MEV by default. Ankr doesn't have a Solana-native Anti-MEV product equivalent — sandwich protection is the customer's responsibility.
Tail latency under congestion. Both can deliver sub-second under typical conditions. Specialisation usually matters at the P95 during peak load.
Stake-weighted relationships. Both support SWQoS at a basic level. Quality varies.
Cost per landed transaction. Ankr's per-credit model charges for sends regardless of outcome. BoltTx's tip-based model charges only on landed transactions.
When to Pick Ankr
- You're multi-chain and want one provider
- Your Solana usage is a small part of overall traffic
- You value pricing simplicity across many chains
- You don't have specific Anti-MEV requirements
When to Pick BoltTx
- You're Solana-focused
- Transaction sending is your core workload
- Sandwich protection by default matters
- Your bot or dApp economics depend on landing rate

FAQ
Can I use Ankr and BoltTx together? Yes — common pattern: Ankr for multi-chain reads, BoltTx specifically for Solana sends.
Is Ankr cheaper than BoltTx? For light usage, Ankr's tier pricing can be cheaper. For high-volume sends, BoltTx's tip-only-on-landed model often comes out ahead.
Does Ankr have Anti-MEV? Not as a Solana-native marketed feature. Customers handle MEV protection separately.
