What to use instead of Fireplace

The product

Fireplace was not a venue. It was a terminal over other people's venues, operated by Enclave HK Limited, whose terms of use — last modified 10 November 2025 and read on 21 September 2026 — describe a platform that lets you "discover, aggregate, and execute trades across regulated third-party prediction markets platforms", naming Kalshi and Polymarket. The same document is blunt about what that means: Enclave "does not create, host, or operate prediction markets directly", does not execute, clear or settle anything, and does not pay out market outcomes. Every trade you placed was executed with the venue underneath.

What you got for that was one screen instead of four. The navigation across the app listed Discover, Markets, Workspace, Portfolio, Wallets, News, Rewards, Watchlist, Disputes and Developer — a position blotter across both venues, a resolution-dispute view, and a news feed matched to the markets a headline moves.

The second business was data. The developer page, read on 21 September 2026, sells a REST and WebSocket API in packs: market-matched news with significance scoring at $300 a month, alternative-data feeds at $300 a month — a Ukraine–Russia control map, a Strait of Hormuz vessel tracker, VIP air-traffic tracking — and wallet tracking across a claimed 12,000-plus addresses at $100 a month, with 10 percent off two packs and a three-day trial. That is a different product from the terminal, and it is the part with no replacement here at all.

How it ended. On 10 August 2026 at 11:03 UTC the company's verified account posted: "We're shutting down Fireplace… The site stays open until the end of September so you can close positions, withdraw funds, and export your account. Please do it before September 30, 23:59 UTC." The wind-down page carries the other date: trading on Fireplace ended on 15 August 2026. No reason is given on either, and none has been given since. Press reports put the public launch at 27 January 2026 and a $1.5 million pre-seed in February — those are secondary sources, and nothing the company publishes carries either date.

This page records 15 August 2026 as the end, because that is the day it stopped being a place you could trade. The 30 September deadline is not the closure; it is the window you are standing in.

What to use instead

The shortest path is the one the wind-down page prints itself: your positions are Polymarket positions and they can be moved to a Polymarket address in one step. If the only thing you wanted from Fireplace was somewhere to click, you do not need a replacement — you need the venue you were already trading on. Everything below is for the parts of Fireplace that were not the venue.

If what you had was two venues in one blotter, Polyrama is the closest thing in the catalogue: Polymarket and Kalshi in one terminal, with wallet P&L, alerts, a strategy DSL, a token-authenticated REST API and an MCP server, on a free tier and with no identity check to look around. Synthesis is the same shape as a browser desk with copytrading and a shared portfolio — read its terms first, because they bar trading from the United States, the United Kingdom and eight other places, which Fireplace's terms did not do by name.

If what you had was the phone, Polycool is a non-custodial iOS, Android and Telegram client for Polymarket with copy trading and parlays. It charges between 1 percent and 0.5 percent per fill on top of the venue, which is a fee Fireplace did not present that way, and it does not cover Kalshi.

If what you had was the whale feed, that separates cleanly from trading. Polysights gives you a live market table, per-wallet P&L and a wallet-flagging screen for Polymarket, free, with nothing to migrate. It is Polymarket-only and its terminal sits behind an access code, so treat it as the tracking half and not the desk.

If you were on the API, take the exit the wind-down page calls "trade via API" seriously and own the layer this time. PMXT is MIT-licensed, covers fifteen venues behind one interface in Python and TypeScript, and runs hosted or self-hosted — so the day its hosted service ends, your code keeps working. polymarket-client is narrower and more direct: Polymarket's own Python SDK, from market data through order signing, with nobody in the middle at all.

If you are in the United States, note that Synthesis and Polycool are barred to you by their own terms, Polyrama is not, and the venue side of the question is Kalshi or Polymarket US rather than the Polygon Polymarket the migration button points at.

What you give up

The news and alternative-data layer, entirely. Nothing in this catalogue matches headlines to the specific markets they move, scores them for significance, or tracks vessels through the Strait of Hormuz and wires the result to a market. Adjacent sells indices and reference rates and Artemis publishes volume and open interest with a methodology, but neither is a signal feed and neither pretends to be. If that $300-a-month pack was why you were there, the honest answer is that you are not replacing it here.

Two venues in one position line. Polyrama and Synthesis both put Polymarket and Kalshi on one screen, but a dollar position on a designated contract market and a USDC position on Polygon do not net against each other in any of them, and they did not on Fireplace either. What you lose is narrower and more annoying: one login, one watchlist, one place where a resolution dispute showed up.

A wallet somebody else kept working. Fireplace provided the wallet, signed the transfers and carried the key. Three of the six picks hand that job back to you — a Polygon address you fund, gas you manage, and a key whose loss is the loss of the balance, with no support address that can help. That is more control and strictly more work, and it is the change most likely to cost somebody money in the week after 30 September.

Somebody to ask. The wind-down page says plainly that support cannot help once the app is offline. Polysights, Polyrama and PMXT are small products with no contractual duty to you either, but at least they are still answering. Anything you wanted to query about a Fireplace fill, a fee or an export has to be queried this month.

Migration notes

The deadline is 30 September 2026 at 23:59 UTC, and it is the whole of the notice. Trading already ended on 15 August. If you have not opened the app since the announcement, the thing to do first is open it and read the balance, not plan.

Cancel resting orders before you migrate. The wind-down page's own second step says so: a resting limit order locks up cash and shares, so the migration cannot move them, and a stale order is a fill you did not want after you have left.

Copy address, not Deposit address. This is the step where money is actually lost. The page asks for the address from Polymarket's profile "Copy address" — the wallet that holds your positions and balance — and warns explicitly against the deposit address. The transfer moves every open position and the entire cash balance in one transaction, it is on-chain, and it cannot be undone. Paste it, then read it back character by character before you press the button.

Export first, migrate second. The announcement lists exporting your account alongside withdrawing, and it is the only one of the three that is irrecoverable afterwards. A fill history you did not download on 29 September is a tax question you cannot answer in March, and neither the venue nor a new terminal has Fireplace's record of what you paid it.

Revoke and forget the API keys. If you were on the paid feed, the keys were scoped, rotatable and issued against a dashboard that is going away. Take the subscription off your card yourself rather than assuming the shutdown does it, and cut the API host out of any running process before it starts failing silently against a dead endpoint.

If you held anything on the Kalshi side, ask now. The published route covers Polymarket only. Kalshi is a regulated exchange where the account is in your own name, so in principle nothing there travels with Fireplace — but "in principle" is not a statement anybody has made in writing, and the only person who can make it is a support agent who stops answering after the 30th.
