**Polygon PoS Bridged DAI** (DAI) is a [stablecoin](https://iq.wiki/wiki/stablecoin) that functions as a trustless, two-way transaction channel between the [Polygon](https://iq.wiki/wiki/polygon) [Proof-of-Stake (PoS)](https://iq.wiki/wiki/proof-of-stake) network and the [Ethereum](https://iq.wiki/wiki/ethereum) [blockchain](https://iq.wiki/wiki/blockchain).

## Overview

Polygon PoS Bridged [DAI](https://iq.wiki/wiki/dai) serves as a crucial component within the [Polygon](https://iq.wiki/wiki/polygon) ecosystem. The primary function of Polygon PoS Bridged [DAI](https://iq.wiki/wiki/dai) is to allow the [DAI](https://iq.wiki/wiki/dai) stablecoin, originally issued on [Ethereum](https://iq.wiki/wiki/ethereum) by [MakerDAO](https://iq.wiki/wiki/makerdao), to be utilized on the [Polygon](https://iq.wiki/wiki/polygon) network. This interoperability is vital for [decentralized finance (DeFi)](https://iq.wiki/wiki/defi) applications and other protocols operating on [Polygon](https://iq.wiki/wiki/polygon), as it provides a stable medium of exchange and a reliable store of value within that environment. By bridging [DAI](https://iq.wiki/wiki/dai), users can participate in [Polygon](https://iq.wiki/wiki/polygon)-based [DeFi](https://iq.wiki/wiki/defi) activities, such as lending, borrowing, and yield farming, without needing to convert their [stablecoin](https://iq.wiki/wiki/stablecoin) holdings into other assets, thereby reducing friction and potential slippage [\[1\]](#cite-id-ZfXaoj7AdO).
