# Scoring is per chain

A single global label for a wallet is the lazy version of this product, and on some chains it is actively misleading. Tachyo scores wallets **per chain**.

The same person can be S-tier on BNB Chain and barely break even on Base. Same human, same discipline, different market, different result. Memecoin flow on Solana rewards different behaviour than early EVM launches, and a track record built in one does not transfer to the other.

## What that means when you read a screen

* A tier badge is always about the wallet **on the chain you are looking at**. On a Solana token page, the tiers describe Solana performance.
* A wallet can appear strong in one part of the platform and unremarkable in another without either being wrong.
* When you follow a wallet because of one chain, check it on the chain you are about to trade before you size in.

## Which chains are scored

Tachyo scores wallets end to end on **Solana, Ethereum, BNB Chain, Base, Robinhood and Stables**.

That list is current, not final. When a new chain starts carrying real volume we add it, rather than waiting for a release cycle, so expect the set to grow as the market moves.

Coverage is not evenly deep everywhere, and the product shows that rather than smoothing it over: a token on a chain where we have thinner history will show more unrated holders. That is a coverage statement, not a verdict on the token.

{% hint style="info" %}
Tokens outside the scored chains can still appear through market data and safety checks, but do not expect a rich tier picture on them. When there is nothing to say, Tachyo would rather leave the column empty than invent a letter.
{% endhint %}

## Why this matters more than it sounds

The single most common mistake in wallet-following is importing a reputation across a boundary where it does not apply: someone was legendary on one chain in one cycle, so their moves elsewhere get treated as signal.

Per-chain scoring is how Tachyo refuses to do that on your behalf.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.tachyo.ai/concepts/per-chain-scoring.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
