# Custom Chain & Token Support

> Expand supported chains or tokens beyond the standard set.

## Custom Chain & Token Support

**Extension tier:** Premium

Rhino supports 20+ chains and a standard set of stablecoins out of the box. The Custom Chain & Token Support extension is for clients whose users hold assets on chains or in tokens not currently in the standard set.

***

## What can be added

* **New EVM chains** — any EVM-compatible chain where Rhino can deploy liquidity and operate a solver
* **New non-EVM chains** — evaluated on a case-by-case basis depending on chain tooling and liquidity availability
* **Additional tokens** — stablecoins or other fungible tokens not currently listed in the bridge config

***

## How to request

Custom chain or token additions are not self-serve. Rhino's engineering team evaluates each request based on:

* Liquidity depth on the target chain
* Security and smart contract auditability
* Operational overhead and monitoring requirements
* Client volume commitment

To request a new chain or token, contact your account representative with details of the chain/token and expected volume.

***

## Timelines

Standard evaluation and onboarding for a new EVM chain takes 1–2 days from agreement. Non-EVM chains vary depending on tooling and liquidity requirements.

Token additions for established stablecoins on already-supported chains are typically faster.
