两百万账户与第三次仪表盘重构

1. 两百万

Sometime around 03:14 UTC on 2026-01-22, account number 2,000,000 finished verification. The records in the signup-svc log show their IP geolocates to Lisbon. They placed their first trade — 0.04 BTC — six hours later. We don't know who they are, and we won't go looking. But thank you, Lisbon.

2. How we got here

We launched in Q4 2022 with twelve trading pairs and a single-page web app. The first 50,000 accounts came in by word of mouth from the engineering and quant Twitter circles. The next 450,000 came from one feature: published 储备金证明 attestation, repeated quarterly, in machine-readable JSON. The next 1.5M came from referral compounding plus the launch of our institutional tier in 2024.

What did not 没奏效的是:付费获客活动。我们试过 — Google、X、播客赞助。每个新增账户的成本始终未低于 180 美元,而典型零售用户的生命周期价值大约只有 90 美元。我们在 2024 年关停了它。

3. 第三个仪表盘

Our customer dashboard has been rewritten twice — 2023 (jQuery → React) and 2024 (React → server-rendered + island components). The third rewrite ships in Q2. Two changes:

内置实时风险引擎

The current dashboard pulls position data once per minute via REST. The new one streams from the matching engine via the same WebSocket protocol our API customers use. Margin liquidation prices, P&L, and portfolio Greeks update tick-by-tick. No more "wait, is this number stale?"

声明式布局自定义

You'll be able to drag-resize the order entry panel, hide the depth chart, swap the order book for a 交易View chart, save layouts per-pair. Sounds basic — and it is, but every previous version had this glued on as an afterthought. Now it's a first-class concept in the layout engine.

4. 规模教会我们的事

Two million accounts means roughly 68,000 simultaneously connected WebSocket clients during the US session, 110,000 active API keys, and ~3 million REST requests per minute peak. The infrastructure footprint we built in 2022 was sized for ~50× this load. We've burned almost none of it on growth — the gap went into shipping more products on the same backbone.

5. 我们保持不变的事

One product team owns one product end-to-end. No "matrix" anything. Engineers respond to their own pages. Every customer-facing decision goes through one person who is on the hook if it goes wrong. As we cross 2M accounts, this is the part we're most worried about losing — but we're keeping it explicit because nothing else works as well at this scale.

6. 接下来

Q2: dashboard ships, locked-deposit terms expand to 180 days, mobile gets a redesign that brings the API trading experience to phones.

第三季度:更深入的市场数据产品 — 完整的历史逐笔归档,达到一定交易量层级以上的账户免费。

第四季度:在三个我们一直等待牌照批准的新司法管辖区进行监管拓展。

同样的文化、同样的团队,更多的产品。感谢您是这两百万分之一。
