Every action on a blockchain — a transfer, a token swap, a contract call — is a transaction. OpenScan.AI lets you inspect every detail of any transaction.
Anatomy of a Transaction
Each transaction on an EVM chain includes:
- Hash — the unique identifier (e.g.
0x…) you use to look the transaction up. - From / To — the sender and recipient addresses. The recipient may be a user wallet or a smart contract.
- Value — the amount of the native coin transferred.
- Input data — the encoded function call when interacting with a contract.
- Nonce — the sender’s transaction counter, which orders transactions per account.
- Gas — the fee paid for execution (see Gas & Fees).
Transaction Status
A transaction ends in one of two states:
- Success — the transaction executed and its state changes are final.
- Failed — execution reverted (for example, out of gas or a failed contract condition). The fee is still consumed because validators performed the work.
OpenScan.AI shows the status prominently on every transaction page, along with the block it was included in and the number of confirmations.
The Receipt
Executing a transaction produces a receipt containing:
- Gas used — the actual computational cost.
- Logs / events — structured events emitted by contracts, such as token
Transferevents (see Logs & Events). - Internal transactions — value movements triggered inside contract execution.
Token Transfers
A single transaction can trigger many token movements. OpenScan.AI decodes ERC-20, ERC-721, and ERC-1155 transfer events so you can see every token that changed hands without reading raw logs.
Tips for Using the Explorer
- Paste any transaction hash into the search bar at xdcscan.io to open its full detail page.
- Use the AI summary on a transaction page for a plain-English explanation of what the transaction did.
- Check confirmations before considering a high-value payment final.
