Angle Documentation Portal

Angle is a decentralized, capital efficient and over-collateralized stablecoin protocol.
Welcome to the Angle Protocol Documentation Portal! It contains essential info and key links to understand the fundamentals of the Angle protocol.
So grab a coffee ☕ and enjoy the read!

🏅 Introduction to Angle

Angle is a decentralized, capital efficient and over-collateralized stablecoin protocol composed of smart contracts running on open blockchains. The protocol was launched in November 2021 and you can start using it at
It can be used to issue stablecoins, called agTokens, that are pegged to a specific value. This means that these tokens are designed to mirror the value of the asset they are pegged to.
Angle has started with agEUR, a Euro (EUR - €) stablecoin.
On top of its stablecoin product, Angle protocol also offers to its users ways to:
  • Trade perpetual futures
  • Earn yield from strategies
  • Get leverage on a wide range of assets
Precisely speaking, the protocol consists of several different modules, or set of smart contracts, from which agTokens can be issued or minted. While Angle was launched with a single minting module (the Core module), a Borrowing module allowing to borrow Angle stablecoins against deposited collateral has been introduced.
The protocol is also engaged into Algorithmic Market Operations (AMOs) where agTokens are invested in protocols for Angle to get a yield on.
Angle Core module is deployed on Ethereum mainnet. It relies on three types of agents that form a balanced ecosystem maintaining agTokens' peg (or stability). These agents are users minting and burning the stablecoins, Hedging Agents covering the protocol collateral from price changes, and Standard Liquidity Providers helping to over-collateralize the protocol in exchange for yield.
Angle Borrowing module is deployed on multiple EVM compatible networks, including Ethereum mainnet, sidechains like Polygon and layer 2s like Optimism. It allows users to deposit collateral and borrow agTokens (debt) against this collateral. It is designed to enable getting leverage on almost any asset through an agToken loan, or to simply let people get access to stablecoins while keeping their exposure to a volatile asset or to a yield-bearing token.
Inspired from more traditional borrowing protocols (like Maker, Abracadabra, Liquity, Aave, Compound, ...), it comes with its set of new features and improvements which make it efficient. Among other things:
  • All operations are designed to be capital efficient
  • The borrowing experience is optimized with notably an improved liquidation engine which allows liquidated addresses to face minimal losses compared with what they can experience in more traditional models.

Other Aspects

Angle is not limited to these key components. It is notably involved in Algorithmic Market Operations where agTokens are invested directly by Angle in other protocols.
Angle also relies on a Governance module to manage the protocol, accessible on Ethereum mainnet.

🛣️ Roadmap

Beyond creating the first liquid and decentralized Euro stablecoin, the main goal of Angle is to create a money layer for DeFi. Angle will not only expand to multiple blockchains or open networks, it will also seek to launch stablecoins for other types of assets.

📐 Discord

Angle is currently being developed by its Core Team and community.
Angle community Discord server is where we collectively organize ourselves to build the best protocol possible, help everyone understand what Angle is about, and most of all have fun playing with DeFi!
📐 If there is anything unclear in this docs or out of date or if you feel like you have feedback on the protocol, this Discord is the best place to let us know!

⚒️ Developers Doc

Angle is an open protocol on which anyone can permissionlessly build or suggest improvements. The protocol relies on an open-source codebase available on Github.
To make things more intelligible, we have a technical doc for developers and users to understand how Angle protocol works under the hood and how to build on top of it. Check it out if you want to understand how the protocol's smart contracts are organized.
The protocol's smart contracts have been audited by Chainsecurity and Sigma Prime. You can find the audit reports here.
