# Changelog

Notable changes to Hexkit and to this documentation.

## 2026-08-31 — Three more known issues fixed

**Clear All no longer deletes your custom signatures.** In the Signature Database
Cache tab, `Clear All` removed the hand-authored custom library along with the three
lookup caches. Custom signatures are authored content, not cache, and now survive a
cache clear.

**Debugger keyboard shortcuts work.** The toolbar advertised `F10`, `Shift+F11`,
`F11`, `Home` and `End`, but only Escape and the arrow keys were bound. Each key now
performs the action its hint names.

**Importing contract artifacts saves on the first try.** The import dialog's primary
button closed without persisting anything; a second, unlabelled step was required.

## 2026-08-27 — Simulation Tx Fee is now computed

The results summary previously displayed `0 ETH` for **Tx Fee** on every
simulation — a hardcoded value sitting beside a correctly computed USD estimate.
The fee is now calculated from the gas the trace reports and the effective gas
price.

This closes the first item under Known Issues below, kept for the record.

## 2026-08-24 — Documentation covering the whole toolkit

The docs now cover every tool in the app rather than the Earn integration alone.

**New guides for the simulator.** [Running a simulation](/guides/simulate-a-transaction),
[reading the results](/guides/read-simulation-results),
[what moved](/guides/asset-changes), [what storage changed](/guides/state-changes),
the [execution trace](/guides/execution-trace), and the
[step debugger](/guides/debugger).

**New guides for inspection and decoding.**
[Decode calldata](/guides/decode-a-transaction),
[identify unknown functions](/guides/signature-lookup),
[add your own signatures](/guides/custom-signatures),
[read contract source](/guides/explore-contract-source),
[compare two contracts](/guides/compare-bytecode),
[inspect storage](/guides/inspect-storage), and
[call a contract](/guides/call-a-contract).

**Known limits are now documented alongside the features.** Storage layout recovery
needs Sourcify specifically; mapping keys are inferred from a 20,000-block log scan
rather than enumerated; token movements are detected only from standard `Transfer`
events; "Full Trace" is filtered for meaning rather than complete; and simulation has
no fallback if the backend is unavailable.

**API reference replaced.** The reference now documents Hexkit's actual server-side
routes — [what they are](/api/introduction) and
[how they authorise requests](/api/authentication) — instead of the sample
specification the site shipped with.

### Known issues

- ~~Tx Fee always reads `0 ETH` on the simulation summary~~ — **fixed 2026-08-27**;
  the fee is now computed from gas used and the effective gas price.
- ~~Importing contract artifacts requires a second step~~ — **fixed 2026-08-31**.
- ~~`Clear All` in the signature Cache tab also deletes your Custom Library~~ —
  **fixed 2026-08-31**; it now clears only the lookup caches.
- **Live Interaction cannot send ETH with a call.** Payable functions can be invoked
  but not funded.
- ~~Some debugger keyboard hints (`F10`, `Shift+F11`) are displayed but not bound~~ —
  **fixed 2026-08-31**; every advertised shortcut now works.

## 2026-08-23 — Documentation site published

First published version, covering the LI.FI Earn integration and the concepts behind
cross-chain vault routes.
