# Supported Assets & Networks

> Fiber is natively EVM-based, with Ethereum serving as its base settlement layer.

Fiber’s privacy infrastructure and stablecoin rewards strategies operate on
Ethereum.

Users can still deposit and withdraw supported assets through selected EVM
networks and Solana. Fiber handles the required routing in the background, so
users do not need to bridge assets manually.

## Currently Supported

| Asset | Networks |
| --- | --- |
| USDC | Ethereum, Base, Polygon, Solana |
| USDT | Ethereum, Base, Polygon, Arbitrum |

Fiber plans to support deposits and withdrawals for additional crypto assets
and networks over time.

## How Fiber Handles Networks

Fiber’s privacy engine is built on [Railgun](https://railgun.org) and settles on
Ethereum. Supported rewards strategies also operate through Ethereum-based
infrastructure.

Deposits from other supported networks are routed into Fiber’s Ethereum-based
private environment. When withdrawing, Fiber routes the assets back to the
network selected by the user.

These steps are handled through Fiber’s interface. Users do not need to
interact directly with Railgun, manually bridge assets, or manage the underlying
network transactions.

## Before Depositing

Only send assets using the networks currently displayed as supported in the
Fiber app.

Do not send:

- An unsupported asset
- A supported asset through an unsupported network
- A different token with the same or a similar name
- Funds to an address generated for another network

Assets sent through an unsupported network or token contract may be delayed,
permanently lost, or unrecoverable.

The Fiber app should always be treated as the current source of truth for
supported assets and networks.
