# usdGG

## Overview

usdGG is a fully backed USD stablecoin (1 usdGG = 1 USDC in reserves) that accrues real yield from cross-chain swap fees on the Genius Bridge Protocol (GBP). Unlike a typical passive USDC holding (which yields 0% when held in a wallet that is not backed by Coinbase), usdGG allows liquidity providers (LPs) to earn a share of protocol fees whenever users swap assets across chains.

The Genius Protocol converts user deposits into USDC (or USDT on certain chains) and holds them in vaults. As cross-chain swaps occur, the protocol collects fees (tiered by swap size) and automatically distributes 90% of those fees to usdGG holders. In essence, usdGG = USDC + continuous fee income, achieved without lending out funds or relying on price oracles (the yield comes solely from swap activity). **To amplify yield without introducing credit risk, Genius integrates** [**M0**](https://docs.m0.org/home/overview/) **as a base-layer for reserve optimization—earning a baseline yield equivalent to the prevailing T-bill rate (\~4%). All swap-based yield is passed back on top of this, allowing usdGG to stack protocol-native income on a risk-free floor.**

Insurance fees are added to the backed USDC to protect against re-orgs and to account for rebalancing fees. This design eliminates traditional counterparty risk from lending, and usdGG's value remains anchored to its USDC reserves at all times. A minimum 25% of each vault's liquidity is kept on-hand to facilitate instant redemptions, ensuring 1:1 convertibility even under heavy usage.
