BoltTx vs Alchemy — Solana RPC Comparison for Trading and dApp Workloads

If you've used Alchemy for Ethereum work, you've probably wondered if it's the right answer for Solana. Alchemy is a serious player with a polished platform and strong developer tooling — for the EVM ecosystem, it's a default choice. For Solana specifically, the answer is more nuanced. The platform that's best-in-class on Ethereum isn't automatically best-in-class on a different chain with different mechanics.

This piece is a direct comparison of BoltTx and Alchemy for Solana, with our biases on the table. We're going to be opinionated where we have a view and honest where Alchemy is the better choice for a given workload.

At a Glance

Quick read: if you're building Solana-first and your workload is transaction-sending heavy, BoltTx fits better. If you're multi-chain or your Solana traffic is read-heavy with EVM context, Alchemy is reasonable.

What Alchemy Is Good At

Honest take on Alchemy's strengths:

Multi-chain coverage. If you're building across Ethereum, L2s, and Solana, having one platform reduces operational complexity. Alchemy handles all of these.

EVM-rich API surface. Alchemy's NFT API, Token API, Webhook system, and parsed data services are mature. For Ethereum-first development, they save real work.

Mature platform. Alchemy has been around long enough that the docs, the support, and the dashboard are polished. Production-ready in a way newer providers aren't always.

Brand recognition. If you're at a company where "we use Alchemy" is comforting to non-engineers, that has value.

For multi-chain dApps where Solana is one of several chains you support, Alchemy is a defensible choice. The trade-off is that none of the chains gets a specialist's optimisation.

What BoltTx Is Built For

BoltTx is narrower on purpose:

• Solana transaction-sending workloads — trading bots, DEX UIs, anywhere transaction landing is the bottleneck
• Sub-second confirmation as a design floor with documented P95 behaviour
• Native Anti-MEV routing — every transaction protected by default, no opt-in
• SWQoS-aware delivery for inclusion under congestion
• Tip-based pricing — costs align with successful trades

If you're not doing those things, BoltTx isn't the right tool. If you are, BoltTx's specialisation matters.

Solana Transaction Sending Specifically

This is where the comparison gets specific. For Solana write traffic:

Latency profile. Both providers can deliver sub-second average confirmation under typical conditions. The question is what happens during congestion and at the P95/P99.

Anti-MEV. BoltTx routes everything through Anti-MEV by default. Alchemy doesn't have a Solana-native Anti-MEV product equivalent — sandwich exposure is the customer's responsibility.

SWQoS. BoltTx has dedicated SWQoS infrastructure with prioritised connections, ensuring your transactions land even during peak congestion. Alchemy's SWQoS support depth depends on its own investment.

Tip strategy support. Both handle priority fees correctly. BoltTx's own submission path ensures high-tip transactions get priority landing capability directly.

Pricing for write traffic. This is where the models diverge sharply. Alchemy's per-credit model charges for every send, landed or not. BoltTx's tip-based model charges only on landed transactions. For high-frequency send workloads with non-trivial failure rates, this is meaningful.

Pricing Comparison

Alchemy uses a credit-based system with monthly tiers. Reads cost credits, sends cost credits, NFT API calls cost credits. Most operations deduct from your balance regardless of outcome.

BoltTx is tip-based. You pay only on transactions that reach the chain.

For a bot doing 1,000 sendTransaction calls per day with 80% landing rate:

• On Alchemy: 1,000 daily sends each consume credits, regardless of outcome
• On BoltTx: tip on 800 landed transactions; nothing on the failed 200

For light read-heavy workloads, Alchemy's pricing is fine. For sustained transaction sending, the unit economics differ meaningfully.

API Surface Comparison

Alchemy provides (Solana-relevant subset):

• Standard JSON-RPC methods
• Some enhanced APIs (varies by chain)
• WebSocket subscriptions
• Webhook integrations
• Multi-chain support (your account works across chains)

BoltTx provides:

• Solana JSON-RPC methods (focused on the write path)
• Per-signature delivery telemetry
• Tip strategy support
• Native Anti-MEV routing as the default path

If you need parsed transaction data, NFT metadata, or token analytics on Solana, neither provider is the best fit — Helius is stronger there. Pair BoltTx for sends + Helius for reads is a common pattern.

Latency Behaviour

For typical Raydium swaps from cross-region clients, both providers can deliver sub-second median confirmation. The differentiator:

• P95 during congestion. This is where the divergence shows up.
• Tail behaviour at peak hours. Worst-case latency under load.
• Time-of-day consistency. Some providers are great during US business hours and worse outside.

The honest answer is that you won't know which is better for your specific workload without measuring. Both have free tiers; run real traffic against both for a week.

When to Pick Alchemy

Pick Alchemy if:

• You're multi-chain and want one provider for everything
• Your Solana usage is moderate and read-dominant
• You value brand maturity and polish
• Your team is already on Alchemy for Ethereum
• You need EVM-rich APIs and Solana is secondary

You'll do fine. The platform is solid for general-purpose use.

When to Pick BoltTx

Pick BoltTx if:

• You're Solana-focused and transaction-sending matters
• You need sandwich protection without separate integration
• Sub-second confirmation under congestion is non-negotiable
• Your bot or dApp economics depend on landing rate
• You want pricing aligned with successful outcomes
• You operate AI agents or trading bots on Solana

We built BoltTx for this workload. If you're it, we want to be the right answer.

Migration From Alchemy

If you're on Alchemy for Solana and want to test BoltTx:

// Before
const connection = new Connection(
  "https://solana-mainnet.g.alchemy.com/v2/YOUR_ALCHEMY_KEY",
  "processed"
);

// After
const connection = new Connection(
  "https://bolttx.io/?api-key=YOUR_BOLTTX_KEY",
  "processed"
);

One URL change. Run side-by-side for a week and compare landing rate, P95 latency, and effective fills (for trading workloads). The data will tell you.

Try BoltTx Side by Side With Alchemy

Sign up for BoltTx (free tier, pay only when transactions land). Run real workload against your existing Alchemy integration in parallel. Don't trust marketing claims — measure.

If your latency and cost profile from Alchemy fit your needs, stay there. We'd rather you make the call on data than because of this post.

FAQ

Is BoltTx an alternative to Alchemy generally? For Solana transaction sending, yes. For Alchemy's broader multi-chain platform, no — they serve different needs.

Can I use both Alchemy and BoltTx? Yes. Common pattern: Alchemy for multi-chain reads or EVM workloads, BoltTx for Solana sends.

What's Alchemy's equivalent to BoltTx's Anti-MEV? Alchemy doesn't have a Solana-native Anti-MEV product equivalent. You'd handle MEV protection separately.

Is Alchemy pricing better than BoltTx pricing? For read-heavy workloads, often yes. For send-heavy workloads, BoltTx's tip-on-landed model usually works out better.

Should I migrate just for Solana, keep Alchemy for Ethereum? Yes — this is the common pattern. Different providers for different chains, optimised for each chain's specifics.
