How to Read a Solana Transaction Before You Sign
A step-by-step method for inspecting instruction lists, token approvals, and program IDs on Solana before approving any DeFi interaction.
Every DeFi action on Solana begins with a transaction proposal in your wallet. Before you click approve, spend thirty seconds scanning three fields: the program IDs involved, the token accounts being touched, and the instruction order.
Program IDs tell you which on-chain programs will execute. If you expect a swap through a known AMM but see an unfamiliar program address, pause and look it up on a block explorer. Solana transactions can bundle multiple instructions — a legitimate swap might include a token account creation step, but an unexpected token transfer to an unknown address is a red flag.
Token approvals deserve equal attention. Some protocols request unlimited delegate authority on your tokens. For learning purposes on devnet this is harmless; on mainnet, prefer exact-amount approvals when the interface allows it.
We teach this inspection routine in the first hour of our foundations workshop because it prevents more mistakes than any single protocol recommendation ever could.
