Indigo Protocol: An Overview

Indigo Protocol is a Cardano-based decentralized finance system that issues synthetic tokens referred to as iAssets. These on-chain instruments are intended to replicate the price movements of various digital or real-world assets, allowing users to gain exposure to those prices without holding the underlying items. The project seeks to expand access to financial products by making a wide array of assets available to holders of cryptocurrency wallets.

Overview

iAssets are created through an over-collateralized debt mechanism. Users place approved collateral, such as Cardano's native token ADA, into smart contracts known as Collateralized Debt Positions (CDPs) to mint the synthetic tokens. The protocol is governed by the Indigo DAO, where staked INDY token holders set parameters and steer future development.

The protocol was launched with a declared "fair launch" approach, meaning INDY tokens were not sold in private investor rounds or pre-sales before mainnet deployment. System stability is supported by coordinated components including Stability Pools that provide liquidity backstops, a liquidation procedure for under-collateralized positions, and a redemption mechanism that enforces iAsset price pegs.

Primary offerings in the Indigo suite include the stablecoin iUSD, which is soft-pegged to the U.S. Dollar, and synthetic cryptocurrency assets like iBTC and iETH that track Bitcoin and Ethereum respectively. A notable feature is CDP Liquid Staking, which permits ADA used as collateral to keep earning network staking rewards, thereby increasing users' capital efficiency.

History

Development work on Indigo spanned nearly two years prior to the public introduction of the protocol. In November 2022, the team ran an Initial Liquidity Event (ILE) in collaboration with the Minswap decentralized exchange to establish price discovery for the INDY token. As part of the community-oriented rollout, Indigo distributed an airdrop of 350,000 INDY to early supporters and to stakers from the Cardano Single Pool Alliance (CSPA).

Indigo Protocol v1 went live on the Cardano mainnet on November 23, 2022, enabling users to mint the platform's inaugural iAsset, the stablecoin iUSD, using ADA as collateral.

After the initial release, the protocol added further iAssets such as iBTC and iETH. A major upgrade, Indigo Protocol v2, introduced significant improvements including CDP Liquid Staking and a framework for interest-bearing iAssets. Proposals and discussions for the V2 design were launched by the Indigo DAO in mid-2023.

Governance

Indigo Protocol's governance is organized around a three-pillar framework intended to promote long-term decentralization and sustainability.

This governance framework is split into three distinct pillars that share responsibility for the protocol's oversight and operations.

Decision-making follows a formalized, multi-stage process. Proposals begin with open discussion on the Indigo Forum as a "Temperature Check." If a concept gains traction, any community member may stake INDY to submit an on-chain proposal; the fee to create proposals rises with the number of active proposals to deter spam. Proposals that meet quorum and majority requirements are enacted automatically on-chain.

Voting is proportional to staked INDY, with one staked INDY equaling one vote. To improve scalability and mitigate network contention, votes are spread across multiple UTXOs or "shards." The protocol also uses Adaptive Quorum Biasing (AQB), a dynamic quorum system in which the required majority is high at low turnout and decreases toward a simple majority (50% + 1) as participation increases, balancing security with voter accessibility.

• Indigo DAO: An association of INDY token holders who have staked their tokens. These members collectively own and control the protocol by voting on proposals that guide its development and risk parameters.
• Indigo Foundation: Registered as a Caymans Limited Liability Foundation Company, it serves as the legal arm of the DAO. The Foundation is responsible for executing off-chain decisions, such as entering into legal contracts or engaging with regulatory authorities, on behalf of the DAO.
• Indigo Laboratories, Inc.: A Wyoming-based development corporation contracted by the Foundation to build, maintain, and upgrade the protocol's smart contracts and applications.

Technology and Mechanics

The protocol is implemented with Plutus smart contracts on the Cardano blockchain and consists of several interrelated modules that support the issuance, exchange, and stabilization of synthetic assets.

iAssets are the protocol's primary instruments. They are fully collateral-backed tokens that aim to track the price of target assets. Indigo offers synthetic exposure to a range of assets including cryptocurrencies (iBTC, iETH), fiat-pegged stablecoins (iUSD), and economic measures such as the Consumer Price Index (iCPI). Users can obtain iAssets by minting them via a CDP or by purchasing them on decentralized exchanges.

Collateralized Debt Positions (CDPs) are the smart contracts that underlie iAsset creation. A user initiates a CDP by locking an approved collateral asset like ADA and may mint a chosen iAsset, which becomes a debt against that collateral. To release the collateral, the user must repay the debt in the identical iAsset they minted, plus any accumulated interest.

• Liquidations: When a CDP's collateralization ratio falls below the MCR, the position can be liquidated. During liquidation, the CDP's debt is extinguished and the locked collateral is seized. The owner of the CDP forfeits the collateral but retains the iAssets they previously minted. This process removes perilous debt from the system.
• Stability Pools: Each iAsset is backed by a corresponding Stability Pool that functions as the primary liquidity backstop. Stability Providers deposit iAssets (primarily iUSD) into these pools. When liquidations occur, the iAssets in the pool are burned to absorb the bad debt. In exchange, Stability Providers receive the liquidated CDP's collateral at a discount and earn INDY token rewards.
• Redemptions: As a secondary, hard-peg mechanism, any user can redeem an iAsset for an equivalent amount of underlying collateral. For instance, 1 iUSD can be redeemed for $1 worth of ADA directly from the system's riskiest CDPs. This creates an arbitrage opportunity if an iAsset trades below its peg, because arbitrageurs can acquire the underpriced iAsset and redeem it for full collateral value, which helps restore the market price and establishes a hard price floor.

Tokenomics

The protocol's economic model centers on two token types: the governance token INDY and the synthetic assets (iAssets), with iUSD being the primary synthetic product.

INDY is the native governance and utility token of the Indigo Protocol.

iUSD is Indigo's native, decentralized, crypto-backed stablecoin, designed to be soft-pegged to the US Dollar.

• Utility: INDY's primary utilities are governance and staking. Holders who stake INDY can vote on proposals in the Indigo DAO. Stakers also receive a share of the protocol's revenue, which is generated from fees for minting, redemptions, and liquidations. These rewards are paid out in real yield, predominantly in ADA.
• Supply and Allocation: INDY has a fixed maximum supply of 35 million tokens. The initial allocation was distributed as follows:
• Stability Pool Rewards: 40%
• Team (Indigo Labs): 25% (subject to a two-year vesting schedule)
• iAsset Liquidity Staking: 15%
• DAO Treasury: 13%
• Governance Participation: 5%
• Airdrop: 1%
• Protocol Owned Liquidity: 1%
