Grouped USD

Introduction

Celeris uses the Grouped USD token or $USD as its primary stablecoin for perpetual trading.

It is automatically minted 1:1 without any fees when a user deposits the underlying USD stablecoin from supported networks, regardless of the amount.

Currently, Grouped USD is backed 1:1 by USDC and axlUSDC from all major chains.

Why use the Grouped USD instead of USDC?

While the Grouped USD only contains USDC tokens as underlying at the moment, more types of stablecoins will be added in the future as more regulated stablecoins launch.

These stablecoins can then be deposited into Celeris without any slippage or fees, regardless of size, improving the onboarding experience. This is only possible because the Grouped USD acts as a basket of different regulated stablecoins.

Celeris has strict criteria for whitelisting constituents and has on-chain safety features.

Example

If Celeris only accepts native USDC from a particular network like Arbitrum, a user holding a large amount (> $1M) of USDC on Osmosis or Base may incur significant fees to bridge and swap it to native USDC on Arbitrum to deposit into Celeris.

With Grouped USD, the user can directly deposit any amount of USDC into Celeris, without swapping or bridging to other networks, and get its full value on Celeris.

Depositing & Withdrawing

Deposits

Any stablecoins from the basket of constituent assets that are deposited into Celeris are automatically converted to Grouped USD at a 1:1 rate. There are 0 fees involved in auto-conversion into Grouped USD.

Withdrawals

Grouped USD will be automatically converted back to any of the underlying tokens at a 1:1 rate. There are 0 fees involved in auto-conversion from Grouped USD.

Rebalancing

Each token has a different amount of liquidity available for withdrawals. If there is insufficient liquidity for a particular token, you may have to wait some time for the liquidity to increase.

This can happen when the liquidity is still undergoing rebalancing, or when other users just withdrew a large amount of one type of token from Celeris.
