Onyx Protocol is a decentralized finance (DeFi) platform built on the Ethereum blockchain. It enables users to lend, borrow, and provide liquidity in a transparent, secure, and immutable manner. Powered by decentralized governance, Onyx Protocol ensures community-driven decision-making and the highest standards of protocol integrity.

Capital inefficiency has hindered traditional decentralized lending protocols, limiting the potential of collateral and digital assets. Onyx Protocol is a decentralized finance platform on Ethereum that lets users lend, borrow, and provide liquidity through a fully decentralized, multi-token system, with support for assets such as ERC-20 tokens as well as NFT standards including ERC-721 and ERC-1155. These platforms often suffer from narrow token support, fragmented liquidity, or centralization, making it harder for experienced crypto users and investors to put more of their holdings to work.

Onyx Protocol addresses these challenges by introducing unified access to aggregated capital and perpetual credit lines designed to improve asset utilization across multiple token types. Powered by the native utility token, Onyxcoin (XCN), the protocol also includes staking, decentralized governance, security-focused infrastructure, the XCN Bridge for cross-chain transfers, and VUSD stablecoin functionality. For readers evaluating advanced DeFi lending and borrowing options—especially those interested in using NFTs and other digital assets as collateral—this guide explains how Onyx Protocol works and where it stands out.

Onyx Protocol is a decentralized finance platform built on the Ethereum blockchain. It offers secure and efficient lending and borrowing solutions. Beyond traditional ERC-20 tokens, Onyx supports a wider range of assets, including ERC-721 and ERC-1155 tokens. Leveraging the power of smart contracts, Onyx provides a transparent and trustless environment for users to access financial services such as lending and borrowing.

Within the Onyx Protocol ecosystem, the utilization of credit lines is a distinguished and unique feature. Offering flexible credit lines without a monthly repayment plan or predefined expiration dates tackling decentralized lending issues creatively. Once accessed and borrowed, these credit lines are perpetual as long as the collateral remains sufficient. This is an innovative approach to DeFi.

How Does Onyx Protocol Work?

Onyx Protocol operates through decentralized smart contracts deployed on the Ethereum chain. These contracts enable the deposit of digital assets, assess the value of the collateral, and issue credit lines based on the provided collateral.

Let’s explore how Onyx Protocol works:

a) Deposit: Users deposit digital assets onto the platform and enable them as collateral.

b) Evaluation: The assets are evaluated based on their aggregate value and collateral factors, determining the maximum credit line available.

c) Credit Line: An algorithmic credit line is issued based on the collateral value without the need for traditional credit checks.

d) Borrowing: Users can borrow Ether or ERC-20 tokens, with interest rates determined by the yield curve for the specific asset.

e) Governance: Governance is handled through the Onyx DAO, where XCN Onyxcoin serves as both a governance token and utility token; XCN is the native asset, and Onyxcoin operates on Ethereum as the native cryptocurrency for community-driven control. Onyxcoin holders and other onyxcoin holders support voting on protocol updates and community initiatives, with token holders participating in decision-making through staking.

Features of Onyx Protocol and Market Capitalization

The Onyx Protocol is a platform designed with a fully decentralized architecture that operates on transparent, open, and credible peer-to-peer smart contracts. Unlike traditional platforms that rely on centralized control, the Onyx Protocol leverages the decentralized nature of the blockchain to ensure that all transactions are transparent, secure, and immutable. The Onyx Protocol consists of the following features:

Onyx Protocol App

The Onyx Protocol lies at the heart of the ecosystem as a decentralized platform enabling peer-to-peer money market lending. It functions through transparent and reliable smart contracts on the Ethereum blockchain, accessible via the Onyx Web App—a user-friendly interface for accessing various services.

VUSD is a virtual USD-based stablecoin fully backed by on-chain reserves and deployed on the Ethereum blockchain. Onyx Protocol, through an approved proposal from the DAO, adds VUSD markets to its decentralized money markets. This will enable users to supply and borrow VUSD on the Onyx Web App. Onyx allocated $50 million worth of VUSD as collateral to facilitate the initial issuance of VUSD.

Onyx Protocol Architecture

A few underlying concepts and technologies help Onyx drive its decentralized finance solution.

oTokens and Total Supply

oTokens serve as the primary mechanism for interacting with the Onyx Protocol. When users engage in actions such as minting, redeeming, borrowing, repaying, liquidating assets, or transferring oTokens, these operations are executed via the oToken contract. oToken is an EIP-20-compliant representation of balances supplied to the protocol. Each asset supported by the Onyx Protocol is integrated through an oToken contract.

By minting oTokens, users accrue interest as the oToken’s exchange rate appreciates relative to the underlying asset. Additionally, oTokens can be used as collateral to borrow assets within the Onyx Protocol.

The protocol offers two variants of oTokens: OErc20 and OEther. Both conform to the EIP-20 standard; however, OErc20 wraps an underlying ERC-20 asset, while OEther wraps Ether itself.

Comptroller

The Comptroller is the risk management layer of the Onyx protocol. It determines how much collateral a user must maintain and how much a user can be liquidated. When a user interacts with an oToken, the Comptroller is asked to approve or deny the transaction. Essentially, the Comptroller maps user balances to risk weights to make its determinations. This layer is part of the protocol’s core infrastructure. The system helps with maintaining secure operation across supported markets.

Governance and Token Holders

The Onyx Protocol is governed by the Onyx DAO, a Decentralized Autonomous Organization, through four key components: staking, the governance module (Governor Alpha), Timelock, and related administrative controls. XCN is the native cryptocurrency and governance token used by token holders for voting on proposals and upgrades through the administrative functions of oTokens or the Comptroller. This supports community-driven governance across the onyx ecosystem.

Security

Through the Onyx Protocol Bug Bounty Program, smart contract codes and balances are publicly accessible for verification. Security researchers are encouraged to participate and are eligible for rewards by identifying and reporting undiscovered vulnerabilities that could lead to asset loss, asset freezing, or user harm. Bounties are awarded based on the severity and exploitability of the vulnerabilities reported.

What is Onyxcoin (XCN)?

Onyxcoin (XCN), an ERC-20 token built on the Ethereum blockchain, serves as the native utility and governance token of the Onyx Protocol. XCN holders are automatically integrated into the Onyx Protocol Decentralized Autonomous Organization (DAO), where the token plays a crucial role in the governance and ongoing development of the protocol.

Tokenomics

The total supply of XCN tokens was initially set at 100 billion units but has been reduced to 48,470,523,779 units following the burning of unclaimed distributions and locked allocations for the team and founders. Currently, 23 billion units are in circulation, while 10 billion units have been allocated to the Decentralized Autonomous Organization (DAO) for grants, incentives, distributions, and other operations. Additionally, 15 billion units have been assigned to the Treasury and are locked in a time-locked smart contract, which will release 200 million XCN tokens monthly over a 75-month period, starting in April 2024.

XCN Token Utility

XCN’s relevance is not limited to the Onyx Protocol but also to the Web3 community. The following are the token utility of XCN:

Payments

XCN is accessible on decentralized and centralized exchanges, enabling its use for trading, bill settlements, and accessing services within the Onyx ecosystem.

Staking

Staking is a process through which holders of XCN lock up their holding to earn a specified amount of APR. Staking XCN serves as an investment opportunity and grants holders the chance to be involved in the governance of the Onyx Protocol.

Governance

The Onyx Protocol is entirely owned and governed by XCN token holders. Their staked XCN tokens are used to vote on protocol improvements and modifications. A minimum stake of 100,000,000 XCN tokens is required to propose changes to the protocol. This governance mechanism has facilitated significant proposals, such as the addition of VUSD markets to the Onyx Protocol’s decentralized money markets.

Onyx DAO App

The Onyx DAO represents the community-driven governance body that oversees the operations and maintenance of Onyx protocol. The DAO manages the Onyx Treasury and makes important decisions through on-chain voting. Onyx utilizes on-chain governance to facilitate transparent and decentralized decision-making. Additionally, Onyxcoin holders can participate in the governance process by staking their tokens and voting on proposals that affect the protocol.

Proposals may encompass a range of changes, such as modifying the interest rate model or introducing support for a new asset. Governance actions can be proposed by any wallet address holding over 100,000,000 XCN in voting power. Once a proposal is submitted, the community has a 3-day window to cast their votes. If the proposal receives a majority approval with a minimum of 200,000,000 votes cast, it is queued in the Timelock and can be executed after a 2-day waiting period.

To access the DAO portal, users must have a reliable internet connection and a supported wallet.

Here’s a detailed guide to help you get involved with the Onyx DAO:

Due to the relatively high gas fees on Ethereum, the Onyx Gas Refund Program has allocated $100,000 in ETH to reimburse users for the gas costs incurred when interacting with the protocol. This applies to gas fees spent on any Onyx smart contracts utilizing the protocol, covering actions such as supplying, borrowing, minting, staking, claiming, and repaying. Refunds are processed weekly, every Friday at 00:00 UTC.
