Unbound Finance: The Cross-Chain Aggregator Layer For AMMs

The decentralized Finance (DeFi) sector has been growing higher since October. Recent charts have shown the values reaching all-time highs in terms of liquidity kept on these protocols. According to Defi Llama, Total Value Locked (USD) has reached a new high, surpassing $276 billion on December 2, 2021. Automated Market Makers (AMMs) have revolutionized the DeFi sector. Liquidity Provider (LP) tokens are used to redeem the underlying liquidity tokens and represent a portion of the liquidity. But users can still not fully utilize the true potential of their capital. Unbound Finance is creating the next money lego by assisting liquidity providers in making better use of their LP tokens to enhance the capital efficiency of AMMs. In this article, we will get a complete understanding of Unbound Finance.


Unbound Finance is a decentralized, cross-chain liquidity protocol that is building the next money lego by unlocking the liquidity from AMMs.

Unbound Finance
Unbound Finance
  • It is the First-Ever-Debt-Free Liquidity Provision System that collateralizes LPTs to generate synthetic assets.
  • It charges no interest and is liquidation-free.
  • It is building the next money lego through unlocking the TVL (Total Value Locked) within the DeFi.
  • It is building a derivative layer on top of AMMs such as Uniswap, Balancer, etc. and unlocking locked liquidity from existing AMM pools and giving loans on existing Liquidity Pool Tokens (LPTs) as collateral.

Problems in Present Defi Ecosystem

  1. Locked Liquidity in AMM Pools
  2. High Demand for a Decentralized Stablecoin
  3. Users’ Collateral is being Liquidated due to extreme Price Wicks caused by Market Volatility.

Solutions by Unbound

  • Synthetic assets such as a Stablecoin (UND), uETH, etc.
  • AMM Pools that are cross derived from multiple AMMs.
  • Oracle Price Feeds based on free markets and path independent value discovery.
  • Building Financial Instruments for compounding yields and margin trades.

Unbound has developed a robust architecture that does not involve a Liquidation Engine. Instead, it includes a combination of collateral ratio, risk control via chosen stablecoin-ERC20 LPT pairings, and SAFU fund offering a far more resilient support system than traditional crypto assets under identical conditions.

Key Highlights

In this section, we will understand the key highlights of Unbound Finance.

  1. Debt-Free: Borrowed funds are interest-free, resulting in a debt-free situation for users.
  2. Liquidation-Free: It does not have a Liquidation Engine. As a result, users are not at risk of liquidating their collateral.
  3. Perpetual Borrowing: Unbound loans do not mature. As a result, users can unlock the underlying collateral at any time by repaying the loan.
  4. Stablecoin UND: UND is a cross-chain stablecoin that is soft pegged to the US dollar.
  5. Factory Smart Contracts: It uses Liquidity Lock contracts designed to be permissionless and supports EVM-based AMMs like Uniswap, Balancer, etc. Unbound will launch support for Non-EVM-based AMMs soon.
Unbound Finance: The Cross-Chain Aggregator Layer For Amms
Key Highlights
  1. Minting Cross Chain Synthetic Assets: Unbound will employ oracles and native bridges to execute UND and other synthetic assets cross-chain transfers.
  2. Secured Price Oracles: Unbound employs Uniswap’s TWAP and Chainlink to receive highly secured price feed, which protects the platform against flash attacks and lowers the reliance on a single price oracle. To know more about Price Oracle Solutions for Unbound Finance, Click here.

How does Unbound Work?

Unbound adds a treasury layer on top of existing AMM platforms by using LPT’s as collateral. The platform provides liquidity to AMM LPTs and issues a Stablecoin (UND) in the form of a minted token. When the UND is returned, the platform unlocks the LPTs, regardless of time.

How Does Unbound Works?
How does Unbound Works?
  • Unlock LPT Liquidity: LPTs are the ideal collateral and are great for funding but are not unsuitable for trading. Unbound will use smart contracts to collateralize LPTs, providing more liquidity while maintaining security.
  • Mint Stablecoin by Locking LPTs: Contracts will lock LPTs and mint a stablecoin (UND).
  • No Liquidation Engine for LargeCap Pairs (Eth/Dai, USDT/USDC, etc.): Smart contracts unlock collaterals whenever the minted UND is returned. Unbound does not charge any penalties if the collateral value falls below a particular amount.
  • SAFU fund: In the event of a very sharp decrease in collateral value, the SAFU fund will absorb some or all of the losses without liquidating the user collateral.

Unbound Finance Core Features

Unbound offers three major services in the form of completely automated Smart Contracts that do not require the participation of a third party. In this section, we will understand the core features of Unbound Finance.

Unbound Finance Core Features
Unbound Finance Core Features


  • When users offer their LPT as collateral, UND tokens and other synthetic assets, including uETH, are minted. UND token is a stablecoin that is pegged to the USD value.
  • Unbound will initially issue UND loans to its users. With the inclusion of new collateral categories, Unbound will give uETH and other synthetic assets as loan issuance tokens.


  • UND is burned during the unlocking process when users give back their minted funds (including the minting fees). This process removes the minted UND from circulation, and the user receives their collateralized LPT back. There will be no additional fees charged to users when they unlock their LPT.
  • Unbound smart contracts are perpetual, which means they do not have a maturity date on the money that has been minted. Hence, there is no deadline to return funds, and users can continue to benefit from their LPT.
  • Unbound users have the option of repaying the entire loan amount in installments over time. Users can unlock assets worth the amount they have paid back. Smart contract estimates the amount of collateral freed at each instance by recalculating the collateralization ratio based on price feed from oracles.


  • Earn feature rewards users for contributing liquidity to the UND pools. Users can add their UND in the Unbound liquidity pools. In exchange, they receive UND rewards proportionate to the value of their deposit.
  • Users can withdraw the deposit made to the liquidity pools at any time, including the rewards.
  • Earn incentives are initially set to 60% of minting fees. The present yield rate is variable and subject to change in the future by community voting.

How is Liquidation Free Liquidity achieved?

In this section, we will understand Liquidation Free Liquidity is achieved in Unbound Finance. It is a 3 step process.

  1. Locking up LPT tokens from large market cap pairs (Eth/Dai,ETH/USDT,DAI/USDT, USDT/USDC, etc).
  2. LTV ratio that does not risk the collateral even during steep corrections.
  3. Maintain a SAFU Fund that with time can act as an insurance fund.

The most significant aspect of utilizing LPT tokens as collateral is calculating the impermanent or divergence loss that could decrease the collateral’s value.

To make it clearer Unbound Team has performed 3 test simulations. The goal of these video simulations is to demonstrate how we calculate impermanent loss by simulating the price drop in Ethereum ETH for an ETH-Dai pool.

  • Simulation 1: 88% Loan To Value. Click here to watch the 1st simulation.
  • Simulation 2: 75% Loan To Value. Click here to watch the 2nd simulation.
  • Simulation 3: 50% Loan To Value. Click here to watch the 3rd simulation.

To know more about complete calculations and results in these simulations, Unbound Team has compiled this docs file.

Terminologies Used in these simulations

  • Loan To Value Ratio (LTV): Loan Minted/Value of The Locked Liquidity Pool Tokens (LPTs)
  • Breakeven Price of ETH: Price at which the Impermanent Loss causes the value of the loan amount equivalent to the value of LPT tokens locked.
  • Loan Minted: Value of LPT Tokens at Breakeven Price
  • Value of The Locked Tokens: Value of LPT Tokens At Start

To know more about complete mathematics used in Liquidation Free Liquidity, Unbound Team has compiled this docs file.

SAFU fund is an insurance fund that can be beneficial in the case of any unpredictable events. The fund will expand indefinitely as a percentage of all minting fees are assigned. This fund maintains the dollar’s peg and produces constant buying pressure on UND. The percentage is initially set at 40% and will change as the ecosystem grows.

Block Limit Lock Mechanism

  • It is one of the protocol’s essential elements for protecting it from flash loans that occur during a single transaction.
  • It is a security protection measure that requires the user to wait for at least three to five blocks for confirmation before interacting with the smart contracts again.
  • The block limit lock has been implemented in Unbound’s Liquidity Lock Contracts (LLC), and the block limit can be altered or withdrawn at any moment based on market conditions.

If a user previously dealt with Mint and wishes to interact with it again at the same moment, they must wait for at least five blocks for confirmation.

Block Limit Lock Mechanism
Block Limit Lock Mechanism

Similarly, in order to unlock again, the user must wait for at least five-block confirmations.


Unbound Protocol is a dual token ecosystem. It uses UND as a Stablecoin and UNB as a Governance Token.

UND Token

  • It is a stablecoin pegged to USD and collateralized by LPT (Liquidity Pool Tokens).
  • Value of UND minted is based on the value of the deposited LPT.
  • Amount of UND minted when the LPT was deposited is the amount that the user must pay back to get their original LPT.
  • Minted UND will be burned once deposited in the Unlock contract before the user returns the original collateral.
  • Arbitrageurs in AMM pools ensure that the Dollar peg is maintained.

UNB Token

  • It encourages token holders to participate in decision-making to address concerns.
  • Token holders will be able to vote on proposed policy changes and implementations and boost the protocol’s efficiency.
  • After two years, a perpetual inflation rate of 4% per year will begin, ensuring continued engagement and contribution to Unbound.
  • Total Supply: 10,000,000,000 UNB
  • Fees collected from minting is distributed as follows:
    • SAFU Fund (40%)
    • UND-DAI Liquidity Pool (40%)
    • Team Fund (20%)

Unbound Finance Upgrades

Till the end of 2021, Unbound Finance has completed all the steps of its 2020-2021 Roadmap. We can see the image below.

In this section, we will understand the New Developments in Unbound Protocol that are coming in the next few years.

Unbound V1

This version will focus on:

  1. Creation of a First-Ever Debt-Free Liquidity Provision System.
  2. Unlocking Liquidity from existing largecap AMM Pools for the UND stablecoin.
  3. Production of Fee-Earning, Non-Tradeable Collateral
  4. Implementation of a SAFU fund.

Unbound V2

This version will focus on:

  1. Unbound Virtual AMM (vAMM): It will introduce a Vault mechanism that will work autonomously, providing automatic liquidity algorithmically.
  2. Unbound Price Oracles: Unbound will develop an on-chain price oracle to query other Smart Contracts to find the latest and most accurate prices to minimize the risk of losses to users.
  3. Unbound Liquidation Engine (for Volatile Pairs): When a specific token value falls below a threshold, Unbound will initiate the liquidation process. Unbound’s community governance will decide which volatile assets will be subject to the liquidation protocols.

Unbound Governance Model

In this section, we will see how Unbound will implement its DAO (Decentralized Autonomous Organization) in the future.

  • This Model allows UNB token holders to vote on platform policies and protocols.
  • A user’s holdings of UNB tokens are proportionate to their voting power on the platform. A user’s voting power grants them the right to engage in policy making, suggestions, and a say in the platform’s future direction.
  • DAO keeps track of the transaction records and regulations that must be executed on the blockchain for Unbound’s protocols to work.
  • DAO stores UNB tokens and releases them when new policies and community improvement ideas are approved. These will be used to fund platform developments.

How to Use the Unbound Finance Testnet?

The protocol has been live on testnet since December 2020. It launched its final Zeta testnet in April 2021. In this section, we will understand how to use its Testnet and use core features.
