# Changelog — SolaceScanScout Explorer

All notable frontend and docs changes are listed here.

## [Unreleased]

### Added

- **Search results list:** When using search (Blockscout `/v2/search`), all matches are shown in a list; user can click a row to open address, tx, block, or token.
- **Tokens page:** Navigation "Tokens" opens a dedicated view that lists tokens from `/v2/tokens` when available, or prompts to use the search bar.
- **Token approval scanner link:** On address detail, a "Check token approvals" link points to revoke.cash (or similar) with the current address and chainId.
- **Contract creation and first/last tx:** Address detail shows "Contract created in tx 0x…", "First seen", and "Last seen" when the Blockscout address API returns `creation_tx_hash` / `first_transaction_at` / `last_transaction_at` (or equivalent).
- **Pagination:** Blocks list and Transactions list support Prev/Next using `page` and `page_size` (25 per page).
- **Event log decoding:** On transaction detail, event logs table has a "Decoded" column; when contract ABI is available from Blockscout, logs are decoded via ethers.js and show event name and arguments.
- **Failed tx rate in Gas & Network:** The Gas & Network card shows "Failed (recent): X%" based on the last 100 transactions.
- **i18n:** New translation keys (Back, Export CSV, Token Balances, Internal Txns, Read/Write contract, Watchlist, Check approvals, Copied) and French (FR) locale option.
- **Copy to clipboard:** Copy buttons on block hash, transaction hash, and address in detail views; toast "Copied" on success.
- **Known-address labels:** Curated labels for CCIP bridges, WETH9/10, CCIP Router/Sender; combined with user-defined labels from localStorage.
- **Address labels in tables:** Latest transactions (home), block detail (miner), transaction detail (from/to), and all-transactions list use `formatAddressWithLabel()` so labels appear consistently.
- **EXPLORER_API_REFERENCE.md:** Section on OpenAPI/Swagger link (if Blockscout exposes it) and "Recent changes" summary.
- **CHANGELOG.md:** This file.

### Changed

- Blocks and Transactions list now load with pagination (page 1 by default; Prev/Next updates the list).
- Search no longer auto-navigates to the first result only; it shows the full search results list for user selection.
- Gas & Network widget includes failed transaction rate when on Chain 138.
