Analyze

aftertx fetches the data, decodes contract calls, traces every fund flow, and runs AI analysis.

One hash. Two worlds.

Same transaction. One view from a block explorer, the other from aftertx.

Everything the block explorer
didn't tell you.

Block explorers show you the data. aftertx tells you what it means.

Plain-English Explanations

Complex contract calls become readable sentences. aftertx decodes what actually happened, not just what the data looks like.

Step-by-Step Breakdown

Every transfer, contract call, and gas charge, ordered and labeled. See the full sequence, not just a summary.

Smart Labels

Each transaction gets tagged instantly, swap, mint, bridge, stake, approve. Your history makes sense at a glance.

Save & Search

Every explanation you generate is saved. Come back anytime, search by address, amount, label, or date.
