# Coverage

> The assets, flows, and networks TetraFi's settlement rails reach.

Coverage has two halves: **which assets** TetraFi is built to trade deep, and **which networks** its settlement rails reach. Both are listed below.

## Asset Classes

TetraFi concentrates on a narrow asset set traded at institutional size - the reasoning is on [Why TetraFi](/why-tetrafi).

### Regulated stablecoins

Where the depth is greatest. Firm LP inventory quotes these directly, at ticket sizes that would move an on-chain pool.

| Group               | Assets                                     |
| ------------------- | ------------------------------------------ |
| USD                 | USDC, USDT, PYUSD, RLUSD, USDG, AUSD, USDS |
| EUR                 | EURC, EURCV                                |
| Regional currencies | BRL, MXN, JPY, KRW, CAD, AUD, ZAR, PHP     |

Issuer mint and burn rails - CCTP, USDT0 and equivalents - compose as legs alongside the quoted liquidity, so a corridor can cross issuers as well as chains.

### Tokenized real-world assets

Quoted the same way, with the issuer's own primary rails available in the same route: subscription, redemption, and secondary trading rather than secondary alone.

* Tokenized treasuries and money-market funds
* Private credit
* Commodities
* Tokenized strategies

Investor eligibility and compliance policy attach to the issuer's capability itself, so an asset that may only be held by qualifying investors stays gated wherever it is routed.

### Everything else

Any ERC-20 an LP is willing to quote is tradeable through the [RFQ API](/rfq-api/introduction), and the [Router API](/router-api/introduction) reaches the wider token universe through DEX, bridge, and fiat sources. The depth claim above applies to the two classes named - reach beyond them is the Router's job.

## Flows

| Flow                 | What it is                                              | The rail                                                                       |
| -------------------- | ------------------------------------------------------- | ------------------------------------------------------------------------------ |
| Secondary trading    | Buying or selling an issued token at size               | RFQ firm quotes, escrow-settled                                                |
| Primary issuance     | Cash into a newly minted token                          | Issuer mint capability, composed as a route leg                                |
| Redemption           | Token back to cash or stables                           | Issuer redemption rail; [T+0 Vaults](/vaults) front the wait for instant exits |
| Cross-chain corridor | The same asset, or a paired one, moved between networks | One intent, one signature, escrowed settlement                                 |

## Networks

These are the networks TetraFi's settlement rails reach today - and the ones arriving next.

<Info>
  Asset and chain support both change over time; the deployment registry is the source of truth for networks, and your workspace's LP roster determines which assets actually quote for you.
