# Beanstalk > A permissionless fiat stablecoin protocol. Beanstalk is a decentralized stablecoin protocol using credit mechanisms to maintain a dollar peg for its native Bean token without collateral requirements. Beanstalk is a permissionless fiat stablecoin protocol built on Arbitrum that uses credit-based mechanisms to issue Bean, a stablecoin pegged to the US dollar. The protocol operates without collateral requirements, instead incentivizing independent market participants to maintain the dollar peg through native financial mechanisms including yield opportunities and debt instruments. Beanstalk migrated from Ethereum to Arbitrum following a 2022 governance exploit and subsequent community-led recovery through the Barn Raise fundraiser. - Type: Protocol - Sector: Finance - Status: Active - Founded: 2021-08-01 - Profile: https://thegrid.id/profiles/beanstalk ## Products - [Beanstalk Protocol](https://thegrid.id/profiles/beanstalk): Beanstalk Protocol is a credit-based peg maintenance mechanism for Bean stablecoin issuance through dynamic monetary policy adjustments. The system utilizes the Silo for yield-generating deposits, the Field for credit facility operations issuing Pods as debt instruments, and the Barn for distributing Bean rewards to Fertilizer token holders. The protocol executes automated peg maintenance through Season-based updates that adjust Temperature parameters, Soil issuance, and Bean minting based on price oracle data from decentralized exchanges. (Stablecoin Issuer, Live, Main Product) - [Basin](https://thegrid.id/profiles/beanstalk): Basin is a composable decentralized exchange architecture enabling composition of arbitrary exchange functions, network-native oracles called Pumps, and exchange implementations into customized liquidity pools called Wells. The protocol provides multi-block MEV resistance through specialized oracle design and supports zero-fee trading through protocol-native incentives. (Decentralised Exchange, Live) ## Assets - [Bean (BEAN)](https://thegrid.id/profiles/beanstalk): BEAN is a USD-pegged stablecoin issued by the Beanstalk protocol on Ethereum and Arbitrum. It is used for payments, as collateral in DeFi applications, and to earn yield through staking in the Silo. The protocol maintains the peg through credit-based mechanisms that attract lenders to burn Beans when the price falls below $1, and mints new Beans to distribute when the price rises above $1, operating without traditional collateral requirements. (Stablecoin) - [BeaNFT (BeaNFT)](https://thegrid.id/profiles/beanstalk): BeaNFT is an ERC-1155 governance token for the Beanstalk protocol. It is used to vote on BeaNFT Proposals that determine the direction of BeaNFT collections, including new collections and collection upgrades. BeaNFTs have historically been awarded to Farmers for interacting with Beanstalk during certain time periods. (NFT) - [Stalk (STALK)](https://thegrid.id/profiles/beanstalk): STALK is the governance token of Beanstalk. It is used to vote on Beanstalk Improvement Proposals and earn Bean seigniorage when the protocol mints new Beans during growth periods. Seeds yield 1/10000 Stalk each Season, allowing depositors to compound their governance power and share of future Bean mints over time.
