Transactions on Solana — What Sending and Breaking Them Taught Me

Short summary

Author learned Solana transactions through hands-on experimentation: sending transfers, tracking confirmation stages (processed → confirmed → finalized), and deliberately triggering failures. This shifted their mental model from abstract API-like requests to concrete understanding of transactions as signed, atomic state-change operations with full lifecycle visibility and diagnostic logging that persists even on failure.

• •Hands-on experimentation revealed transaction structure beyond API-request analogy
• •Confirmation tracking clarifies settlement stages and network state changes
• •Failed transactions produce signatures, instructions, logs, and fees—revealing transaction completeness
