Auto-translate crypto Twitter: read foreign posts in English

Quick answer: Auto-translate adds an English rendering of a non-English post inside the alert itself, so a Chinese, Korean or Russian post arrives already readable instead of sending you to a translation tab. The language check runs locally on every post before anything is sent anywhere, and the whole step is fail-open: if translation is slow or unavailable, the alert still goes out, untranslated. It never holds an alert hostage.

Why it matters more than it sounds

A meaningful share of crypto news breaks first in Chinese and Korean, and a good deal of it in Russian. If your tracker forwards the original text and nothing else, you are in a race against people who read it natively, and you lose that race by however long it takes you to notice the post is not English, select it, paste it into a translator, and read the result. That is fifteen to thirty seconds on a good day. On a launch, that is the whole opportunity.

Worse is the post you skip. A wall of characters you cannot read looks like noise, and noise gets scrolled past. Translation in the alert changes the default from "ignore unless I make an effort" to "read it".

How the language check works

Deciding whether a post needs translating happens locally, before any network call, using the script the text is written in. Any post containing non-Latin characters — Chinese, Japanese, Korean, Cyrillic, Arabic, Hebrew, Greek, Thai, Devanagari — is provably not English and goes for translation. Pure Latin text is assumed English and skipped, unless it carries letters English does not use: ñ, ç, ß, ğ, ş, ã, ø and their relatives.

The check is deliberately biased toward not translating. A redundant "translation" appended to an English post looks broken and trains you to distrust the feature, so the design accepts missing an occasional borderline case in exchange for never producing nonsense on a post you could already read.

Before the check runs, the text is stripped of the things that are not natural language — links, handles, cashtags, emoji and punctuation. Otherwise a post that is mostly a URL would be judged on the URL rather than on the sentence.

It cannot delay your alert

This is the design constraint that matters most, and it is worth being precise rather than saying "instant". Translation is an extra step, and extra steps in an alert pipeline are exactly how alerts arrive late.

So the step is bounded and fail-open. Each attempt runs against a tight timeout, the whole translation has a hard total budget of a few seconds, and any failure — timeout, error, service unavailable, rate limit — produces no translation rather than an error, and the alert is delivered unchanged. There is no path in which a translation problem makes an alert late or makes it vanish. For context on the rest of the timing, see how fast is X-Relay: we re-check a tracked account as often as every 300 ms, and our fastest measured detection was 281 ms.

Why it does not cost you rate limits

Three things keep the number of translation calls low, which is what keeps the feature reliable rather than throttled:

• Local detection first. Only text that is genuinely non-English is ever sent. English posts never leave the box.
• A cache keyed on the normalised text. Each distinct string is translated once, ever — and then reused. Copypasta, which crypto Twitter produces in industrial quantities, translates once and is free from then on.
• Duplicate collapsing. If the same string arrives on several trackers at the same moment, the concurrent requests merge into one call rather than racing each other.

What it will and will not do

• It will translate Chinese, Japanese, Korean, Russian and other non-Latin-script languages, and Latin-script languages carrying non-English letters.
• It may skip a Latin-script language written without accents — Indonesian, Malay, or Spanish typed without diacritics can read as English to a script-based check. This is the acknowledged cost of not over-translating.
• It is machine translation. Expect the gist, not the nuance. Slang, irony and community in-jokes survive badly, and crypto Twitter is mostly slang, irony and in-jokes.
• It does not read images. Text inside a screenshot is not translated, because it is not extracted in the first place.
• It does not change detection. Contract addresses and cashtags are read from the original post, so CA detection works identically whether or not the post is in English — a contract is a contract in every language.

Where it applies

Translation runs on every activity a tracker delivers, not just top-level posts. That includes replies and quote tweets, which is the case that matters most — a foreign-language reply under an announcement is both the hardest thing to notice and the most likely place for a contract to appear. It applies the same way whether the alert lands in Discord or Telegram.

Setting it up

1. Add the accounts or X Lists you want, including foreign-language KOLs, project accounts and news sources.
2. Nothing else — translation applies automatically to posts that need it.
3. The alert carries the original text and the English rendering together, so you can see what was actually written rather than only what a machine made of it.
