Busan · Solana Learning Library
Read how Solana transactions actually move, settle, and confirm
Smart FieldBase publishes plain-language guides on transaction anatomy, priority fees, and confirmation levels — plus small-group workshops for builders and analysts who want to trace real on-chain activity.
What we cover
From instruction layout to finality — explained in order
Our library focuses on the mechanics readers ask about most: how a Solana transaction is built, what each account slot does, why fees spike, and which confirmation level matters for a given use case.
Transaction structure
Signatures, message headers, account keys, and instruction data — mapped to what you see in an explorer.
Fee mechanics
Base fees, compute units, priority fees, and when a higher bid actually changes inclusion order.
Confirmation levels
Processed, confirmed, and finalized — what each stage means for transfers, swaps, and program calls.
Live walkthroughs
Small-group sessions where an instructor traces real transactions step by step on screen.
Sessions
Learning sessions you can reserve
Each session is led by a Smart FieldBase instructor and limited to eight participants so everyone can ask about their own transaction examples.
Fee Estimation Clinic
90-minute clinic on reading compute budgets, setting priority fees, and interpreting failed transactions caused by insufficient fees.

Confirmation Levels Briefing
One-hour briefing on when to wait for finalized status, how reorgs affect reads, and what RPC methods return at each stage.

What participants say after a session
After the anatomy workshop I could finally explain to our compliance team why a failed token transfer showed a specific program error — not just "transaction failed."— Hye-jin K., operations lead at a Busan fintech team
The fee clinic was dense but well paced. I wished we had one more worked example on compute unit limits, though the follow-up email with links helped.— Marcus L., independent validator operator
