Frequently asked questions
What is a transaction hash?+
A transaction hash is a unique ID for a completed blockchain transaction. It usually starts with 0x and is 66 characters long. You can copy it from a wallet or a block explorer.
Which networks are supported?+
Version 0.1 supports Ethereum, Base, Arbitrum, Polygon, BNB Chain, Optimism, and Avalanche.
Do I need to connect my wallet?+
No. Transaction Explainer only analyzes completed on-chain transactions. There is no wallet connection or signing.
Does Transaction Explainer determine whether a transaction is safe?+
No. It helps you understand activity such as transfers, approvals, and fees. It does not score risk or detect scams.
What transactions can it explain?+
Native transfers, token transfers, approvals, swaps, claims, contract interactions, gas fees, and wallet impact — based on what is visible on-chain.
Do you collect transaction hashes or wallet addresses?+
No. Explanations are generated on demand from public blockchain data. Analytics events never include transaction hashes or wallet addresses.
Transaction Explainer helps make blockchain activity easier to understand. It does not determine whether a transaction, token, contract, or protocol is safe.
