# Symbol Packs

> Preset universes you can copy into config/user.yaml.

b1e55ed’s **universe** controls which symbols producers collect and the brain scores.

Config key:

```yaml theme={null}
universe:
  symbols: ["BTC", "ETH", "SOL"]
```

***

## Preset packs

### Majors

* BTC
* ETH
* SOL

```yaml theme={null}
universe:
  symbols: ["BTC", "ETH", "SOL"]
```

### Extended Majors

* BTC, ETH, SOL
* SUI, HYPE
* AVAX, LINK, MATIC

```yaml theme={null}
universe:
  symbols: ["BTC", "ETH", "SOL", "SUI", "HYPE", "AVAX", "LINK", "MATIC"]
```

### DeFi

* UNI, AAVE, CRV, SNX, COMP, MKR

```yaml theme={null}
universe:
  symbols: ["UNI", "AAVE", "CRV", "SNX", "COMP", "MKR"]
```

### L1/L2

* ETH, SOL, AVAX, NEAR, ATOM, DOT, SUI

```yaml theme={null}
universe:
  symbols: ["ETH", "SOL", "AVAX", "NEAR", "ATOM", "DOT", "SUI"]
```

### Memes

* DOGE, SHIB, PEPE, WIF, BONK

```yaml theme={null}
universe:
  symbols: ["DOGE", "SHIB", "PEPE", "WIF", "BONK"]
```

### Runtime bundle packs (wizard/API)

These packs are available in the setup wizard and `GET /api/v1/universe/packs`:

* `tradfi-infra` — direct TradFi plumbing coverage for BTC/ETH/SOL
* `hl-tradfi-perps` — Hyperliquid-perps style basket with TradFi factor overlays
* `mixed-market` — blended direct + proxy basket

#### Direct vs Proxy mappings

* **Direct**: the symbol has first-order feed coverage in current producers (higher confidence).
* **Proxy**: the symbol is mapped to an anchor symbol/factor basket (rates, dollar, vol, beta, liquidity) when direct coverage is weaker.

Proxy mappings are practical scaffolding — they improve coverage without pretending to be a full factor model.

## Custom pack

Define your own universe in `config/user.yaml`:

```yaml theme={null}
universe:
  symbols: ["BTC", "ETH", "SOL"]
```

<Tip>
  Start smaller than you think. A tight universe improves signal quality and reduces producer noise.
