# SwissDLT Explorer

> Read-only, static block explorer for SwissDLT, a Swiss consortium chain (chain ID 94, go-ethereum Clique proof of authority, four-second blocks, native coin BCTS with 18 decimals). The browser reads blocks, transactions, addresses and contract code directly from the public RPC endpoints https://rpc.swissdlt.ch and https://rpc2.swissdlt.ch and compares both endpoints on the same block hash. An hourly indexer publishes GOG voucher-transfer activity and an Urstamm candidate registry as open JSON and Atom files. Nothing in the explorer signs or sends transactions.

Explorer views are client-side routes in the URL fragment (`#/...`), so they need JavaScript. For machine use, read the data files below or call the public JSON-RPC endpoints directly. `https://explorer.swissdlt.tech/?q=<block number, hash or address>` opens the matching lookup in a browser.

## Explorer views

- [Network dashboard](https://explorer.swissdlt.tech/): live head, block cadence, consensus health of both RPCs, recent blocks, GOG activity patterns and exports
- [Block lookup](https://explorer.swissdlt.tech/#/block/27317100): `#/block/<decimal number or 0x block hash>`; header fields, UTC timestamp, gas, Clique vote field, transaction list
- [Transaction lookup](https://explorer.swissdlt.tech/#/tx/0xbda8499f42d4528a7dc00316e20587917c5349fa28b73364e41e730c6d47959a): `#/tx/<0x hash>`; status, block, from, to, value, nonce, gas, event-log count
- [Address lookup](https://explorer.swissdlt.tech/#/address/0x43cf6bfb19422e5a9ae2a411929f7e48d7e7106f): `#/address/<0x address>`; BCTS balance, nonce, code size, reference token balances
- [GOG voucher activity](https://explorer.swissdlt.tech/#/app/gog): acrevis / Gossau voucher token transfers with filters, metrics, CSV export and browser alerts
- [Urstamm product passports](https://explorer.swissdlt.tech/#/app/urstamm): candidate registry, certificate views, local SHA-256 checks and QR verification links
- [Certificate view](https://explorer.swissdlt.tech/#/certificate/0x395a77b43a352890018f7f76694b175e4fe5555e): `#/certificate/<0x contract address>`

## Data files and feeds

- [GOG activity JSON](https://explorer.swissdlt.tech/data/gog.json): Transfer events of the GOG token with block timestamps and coverage metadata (`coverageStart`, `lastIndexedBlock`); event identity is `transactionHash:logIndex`; values are raw integer strings with 18 decimals
- [GOG Atom feed](https://explorer.swissdlt.tech/data/gog-feed.xml): latest 25 GOG events, for feed readers and alerts
- [Urstamm registry JSON](https://explorer.swissdlt.tech/data/urstamm-registry.json): Urstamm identity, candidate contracts and verification status (unofficial candidates)
- Files under `/data/` allow cross-origin reads (`Access-Control-Allow-Origin: *`) and are cached for five minutes

## Machine-readable files

- [Contracts the Explorer tracks](https://explorer.swissdlt.tech/.well-known/contracts.json): chain 94; GOG token, Urstamm identity and candidates, reference tokens and ChainBridge, each with its explorer link, observed code size and the code or data file it comes from
- [Minimal ERC-20 ABI](https://explorer.swissdlt.tech/.well-known/abis/erc20-minimal.json): the balanceOf, name, symbol, totalSupply calls and the Transfer event the Explorer uses; not verified source
- [Thirdfy app manifest](https://explorer.swissdlt.tech/thirdfy-app.json): appId `swissdlt_explorer`, kind `data`, `rest` upstream, two read actions (`get_swissdlt_gog_activity`, `get_swissdlt_urstamm_registry`); mirrored at `/.well-known/thirdfy-app.json`; prepared for submission, not submitted or listed
- [Thirdfy readiness](https://explorer.swissdlt.tech/.well-known/thirdfy-readiness.json): validation results and open gates; the Explorer has no MCP endpoint
