How Solana Transactions Are Different from REST API Calls (And Why It Matters)

Short summary

Solana transactions are fundamentally different from REST API calls: they're stateful, cryptographically signed instructions that charge fees even on failure. Unlike HTTP's immediate response, Solana transactions progress through three commitment stages (processed, confirmed, finalized) with different security guarantees. Professional developers simulate transactions before sending to catch errors and avoid wasting fees.

• •Solana charges fees for failed transactions; REST APIs don't
• •Transactions have 3 commitment stages vs HTTP's single response
• •Simulation validates transactions risk-free before sending
