STAGE 1

The Trading Interface

AutEx was the first — and, before the stand-down, the only — execution venue to ship against the DCC. This is a faithful recreation of its interface.

Try the BUY/SELL buttons above — they only flash. The real order lifecycle is simulated in Stage 2, below, where clearing actually happens.
The full products list — every active contract, with ticker codes and next data date — lived at autex.exchange/products. An October 2025 writeup described AutEx as "expected to be open-sourced soon so others can deploy similar exchanges" — it shipped Dec 3, 2025, publicly, as AFX (see Page 1, History).
STAGE 2

Placing an Order

Watch where AutEx's job ends and AFP's job begins. Enter a price and quantity, then place the order.

Try changing the price and quantity below, then place the order — watch the log and the DCC receipt update as it clears.
OPEN ORDERS (0)
TRADE HISTORY (0)
No open orders. Place an order above to begin the simulation.

This is where AutEx ended and AFP began. AutEx matched the order. AFP cleared it — updating the on-chain margin balance and open interest ledger. When AutEx went offline in Season 1, this bottom layer kept running. → Page 4 goes deeper on where execution ends and clearing begins.
Market making was one of Forecastathon's four officially scored competition categories — this bot mode is a facsimile of that role: quote both sides, get lifted on one, re-center and quote again.
STAGE 3

Architecture Layers

AutEx was never the whole system — only the top layer. Click each layer to see what it actually held.

AutEx is only the interface. The AFP SDK (Python, PyPI: afp-sdk) made it possible for any developer to connect a new execution venue and trading modality to the same clearing layer. The slot for Venue B was always open — and, per community accounts, it wasn't entirely unused.
Nothing above required AutEx's UI to verify. The AFP Explorer (afp.network) is a separate front end for AFP data — Products, Accounts, Trades, and Activity by address, including liquidation and bankruptcy events at the contract level, independent of any single venue. AutonityScan (autonityscan.org) covers the underlying chain itself — blocks, transactions, and contract calls. web3cdn built a second execution venue against the AFP DCC, alongside its confirmed RPC and indexing infrastructure work for Autonity — it was live, but never whitelisted for production trading (→ Page 3 covers the DCC and the AFP SDK this second venue connected to). A separate community project, the Centralized Auton Exchange (CAX), was released during the PCGC testnet rounds — a third example of the permissionless-venue slot being exercised, distinct from both AutEx and web3cdn's venue. Two other short-lived PCGC-era community dapps, for context: tknzd, an NFT trading platform (rounds 4–5), and a front-end deployment of the Perpetual Protocol project, Margined — neither connected to the AFP DCC.
STAGE 4

The Stand-Down Artifact

Same nav, same status bar, same ticking clock. Only the products disappeared.
