**USDB** is the native [stablecoin](https://iq.wiki/wiki/stablecoin) of the [Blast](https://iq.wiki/wiki/blast) Network, an [Ethereum](https://iq.wiki/wiki/ethereum) [Layer 2](https://iq.wiki/wiki/layer-2) scaling solution. USDB is designed to provide stability and yield by automatically adjusting its supply to maintain its peg to the US dollar while generating returns for its holders.

## Overview

USDB is a self-rebasing, yielding stablecoin native to the [Blast](https://iq.wiki/wiki/blast) Network. The USDB supply automatically adjusts to maintain its value and generate yield. [\[3\]](#cite-id-tp4xyw7svc) [\[4\]](#cite-id-ai1amc4zhnf)

#### Key Features

* Auto-Rebasing Mechanism: USDB’s supply automatically adjusts to keep its value pegged to the US dollar. This mechanism operates for both individual accounts and [smart contracts](https://iq.wiki/wiki/smart-contract).
* Yield Generation: USDB earns yield from [MakerDAO’s](https://iq.wiki/wiki/makerdao) on-chain T-Bill protocol. This yield is accrued automatically, providing passive income to holders.
* Integration with Blast Network: As part of the [Blast](https://iq.wiki/wiki/blast) Network, an [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm)-compatible USDB aims to benefit from faster and cheaper transactions while maintaining [Ethereum](https://iq.wiki/wiki/ethereum)-level security.

## How USDB Works

#### Bridging & Redemption

USDB is acquired by bridging [stablecoins](https://iq.wiki/wiki/stablecoin) like [DAI](https://iq.wiki/wiki/dai), [USDC](https://iq.wiki/wiki/usdc), or [USDT](https://iq.wiki/wiki/tether) from the [Ethereum](https://iq.wiki/wiki/ethereum) mainnet to the [Blast](https://iq.wiki/wiki/blast) Network, converting them into USDB. USDB can be redeemed back to DAI when needed.  [\[5\]](#cite-id-2ua0abh6c0x) [\[6\]](#cite-id-ov4m48vh2zi) [\[7\]](#cite-id-39m5k00j7gt)

#### Non-Rebasing Option

For applications requiring stability without dynamic adjustments, USDB offers a non-rebasing version, nrUSDB. This token wraps USDB at its current value and can be unwrapped later. [\[8\]](#cite-id-yare8vxm3i)

USDB combines the stability of a dollar peg with yield generation through [DeFi](https://iq.wiki/wiki/defi) protocols. Its integration with the [Blast](https://iq.wiki/wiki/blast) Network enhances scalability and reduces transaction costs, making it an asset in the DeFi landscape.
