On-chain credit offers a transparent and efficient alternative to traditional credit systems that use blockchain to assess creditworthiness and facilitate loans.
Enter on-chain credit
On-chain credit refers to a decentralized lending system that operates entirely on blockchain networks. Unlike traditional credit systems that rely on centralized authorities such as banks or credit agencies, on-chain credit utilizes smart contracts, digital assets, and verifiable on-chain data to facilitate transparent, efficient, and permissionless credit transactions.
Ultimately, on-chain credit enhances accessibility without the traditional barriers requiring collateral, without compromising security, verifiability, and transparency.
Although decentralized lending has seen significant growth in recent years, we are still in the early stages of the broader evolution of DeFi into traditional credit offerings. However, with the emergence of on-chain credit protocols, there are signs of accelerated adoption and potential disruption of traditional lending models.
According to RWA.xyz, the value of tokenized private credit was over $9.68 billion in January 2025, up from approximately $900 million in 2021, representing a remarkable growth of over 930% in just three years.
How does on-chain credit work?
On-chain credit typically uses blockchain, smart contracts, and decentralized identities to facilitate loans and financing without traditional intermediaries.
In general, there are five phases:
Borrower Integration
Solvency Assessment
Loan Issuance
Disbursing Loans
Handling Defaults
Borrower Integration
Borrowers use blockchain-based identities that aggregate on-chain and off-chain data, such as transaction history, assets, and reputation. This serves as an alternative to traditional credit scores.
Anyone with a cryptocurrency wallet can apply for credit. Thus, the bureaucracy typically associated with banks is completely eliminated.
Assessing Credit Capacity
Credit assessment on DeFi platforms involves evaluating a user's profile based on their on-chain activities, such as transactions and wallet behavior. This process analyzes the overall loan history, grants, and cryptocurrency transaction patterns on DeFi platforms.
Platforms can generate a credit profile that reflects the borrower's payment history and reliability by examining detailed on-chain user data, such as token holdings and previous loan payment records. This decentralized yet transparent approach eliminates the need for traditional credit scoring and allows for more inclusive lending.
Loan Issuance
After solvency assessment, loans are issued through smart contracts, which automate the entire contracting process. Smart contracts encode the terms of the loan, such as interest rates, payment schedules, and collateral requirements, ensuring execution without the need for intermediaries.
Loans can be of two types:
Collateralized: Borrowers provide digital assets such as cryptocurrencies, NFTs, or tokenized invoices as collateral. The smart contract locks these assets, ensuring they remain inaccessible to the borrower until the loan is repaid.
Unsecured:Emerging models use decentralized reputation systems or social credit to offer unsecured loans. This relies on advanced risk modeling and community-driven trust systems.
Disbursing Loans
Once the terms of the loan are finalized and the collateral (if any) is locked, the loan amount will be automatically disbursed through the smart contract. This disbursement typically occurs in the form of stablecoins or other cryptocurrencies.
Dealing with Standards
If a borrower does not repay the loan as per the agreed schedule, the protocol initiates predefined steps to mitigate lenders' losses. These steps are entirely governed by the smart contract, ensuring fairness and transparency.
Here’s how a typical default management process looks:
Settlement: In the event of borrower default, collateral is automatically liquidated by the smart contract to repay the loan amount. This protects lenders from financial losses.
Penalty mechanisms: borrowers may incur additional penalties, such as a reduction in their trust score or higher interest rates on future loans.
Reputation impact: defaults are recorded on-chain, affecting the borrower's decentralized credit profile. This ensures that future credit assessments accurately reflect the borrower's history.
Huma Finance manages defaults by granting borrowers a grace period to settle. If not, the Assessment Agent (AA) declares default, suspending new deposits and allowing withdrawals and amortizations. Losses are first covered by reserve funds, and any unpaid profits are shared with lenders.
If borrowers pay later, the recovered money will be used to pay senior creditors first and then others. Once enough funds are recovered, the Huma Pool can be reopened for normal use, ensuring fairness for all creditors.
Technical Components in an On-Chain Credit System
An on-chain credit system incorporates various blockchain-based components to facilitate lending and borrowing. Below are the key technical components:
Decentralized Oracles
Decentralized Identifiers (DIDs)
Smart Contracts
Decentralized Oracles
On-chain credit systems rely on decentralized oracles to provide real-time data from external sources, including real-time prices, updated liquidity pool details, and current market conditions. These oracles collect off-chain information and deliver it to their smart contracts to ensure that credit assessments remain accurate and up-to-date.
By utilizing decentralized oracles, DeFi platforms can dynamically adjust risk factors and collateral requirements, making the lending process more responsive to changing market conditions. This approach facilitates flexibility in on-chain credit, allowing it to better reflect actual asset price fluctuations and provide more customized lending solutions to its users.
Smart Contracts
Smart contracts are the backbone of on-chain credit systems, automating every step of the lending process, from loan issuance to repayment and settlement.
To maintain security and reliability, these contracts undergo thorough audits to identify vulnerabilities, such as reentrancy attacks or logical flaws.
Smart Contract Security Audits
The security and reliability of smart contracts are crucial for executing DeFi loans and assessing credit risk. Smart contracts, which play a crucial role in automating the lending process, must undergo rigorous audits to ensure they are free from security vulnerabilities.
A proper audit conducted by trusted companies with extensive experience in the cryptocurrency sector ensures that contracts are executed as expected, protecting both lenders and borrowers. With a secure framework, the DeFi lending ecosystem becomes more reliable, reducing the risks of exploitation or fraud that can compromise users' funds and personal data.
Decentralized Identity (DID)
Decentralized identity systems are the foundation of user verification and credit assessment in on-chain credit systems. Unlike traditional systems that rely on centralized credit agencies, DIDs aggregate on-chain data, such as transaction history, wallet activity, and staking records, as well as off-chain data through cryptographic verifications.
Borrowers can create a self-sovereign identity, maintaining full control over their personal data and selectively sharing it with lending platforms. This ensures privacy and allows lenders to assess credit capacity based on a transparent and tamper-proof data trail.
However, DIDs are not currently widespread or common. The lack of awareness and adoption among the general population makes it difficult for potential borrowers to create self-sufficient identities. Huma takes a different yet familiar approach.
Huma Finance utilizes Persona to manage its Know Your Customer (KYC) and Know Your Business (KYB) processes. Persona is a trusted compliance platform specializing in identity verification and regulatory compliance, ensuring that Huma Finance operates within legal and secure frameworks.
Benefits of On-Chain Credit
Enhanced Accessibility
One of the standout features of on-chain credits is their ability to make financial services accessible to a much broader audience, regardless of geographic location. Traditional credit systems often leave out individuals without formal credit history or those in regions with limited access to banking services.
The use of decentralized data, such as transaction history, user activity, and reputation systems, to evaluate solvency eliminates the need for traditional credit scores and the intermediaries behind them. This innovation opens the door for tens or even hundreds of millions of people who previously had no way to prove their solvency, enabling them to borrow, lend, or invest like never before.
Capital Efficiency
In traditional finance, access to capital involves complex and time-consuming bureaucracy, long approval timelines, and strict eligibility criteria that also vary from lender to lender. However, when it comes to on-chain credits, blockchain technology simplifies this process, enabling instant and transparent access to lines of credit, with secured funds remaining on-chain.
This availability of collateralized funds contributes to capital flowing more freely, with a lower risk of retention or misallocation. It allows individuals and institutions to optimize their capital usage, fostering a healthier and more dynamic ecosystem and making the entire financial system more agile and efficient.
Driving Financial Inclusion
Financial inclusion has long been a goal for governments and policymakers but has remained distant for many parts of the global population, such as developing and underdeveloped regions. On-chain credits are filling this gap by providing access to credit for those who have traditionally been excluded from the financial system, such as the unbanked population.
With the help of blockchain technology, credit can be granted based on an individual's behavior within the decentralized ecosystem, rather than solely on their traditional financial history. As a result, individuals in regions with insufficient or unbanked access can participate in the global economy, access loans for housing, education, businesses, or other personal needs, and build their credit profiles without relying on traditional banks.
Transforming Lending Markets
Centralized gatekeepers, biases in credit scoring, and processing delays have long restricted traditional financial systems. With on-chain credits, all intermediaries are eliminated, allowing the transparent and immutable nature of blockchain to ensure that credit history and loan conditions are accessible, reliable, and secure.
Both borrowers and lenders can interact directly without intermediaries, resulting in faster transactions, more competitive interest rates, and a broader range of opportunities. On-chain credit ratings based on decentralized and real-time data eliminate friction from traditional credit models, creating a more inclusive market.
Greater DeFi Flexibility
On-chain credits bring new flexibility to the DeFi space with their adaptable, efficient, and secure credit systems as a foundation. They enable seamless interaction with a variety of DeFi protocols, whether for lending, staking, or providing liquidity.
Unlike traditional loans, which are tied to rigid terms and conditions, on-chain credit allows for personalized adjustments, with smart contracts automatically adapting to user needs. This flexibility not only enhances user experience but also encourages innovation in the DeFi sector, enabling users to manage their assets more effectively and unlock new financial opportunities.
Why is on-chain identity important?
On-chain identity is a digital identity created, maintained, and verified directly on a blockchain. It allows individuals and entities to manage and prove their identity securely, without relying on centralized authorities, ensuring greater privacy, transparency, and control over personal data.
On-chain identity plays a crucial role in the on-chain credit system in the following ways:
Reliable credibility assessment: on-chain identity ensures that individuals' financial behaviors, transaction histories, and other digital reputations are securely linked to a verified identity.
Fraud and identity theft prevention: on-chain identities reduce fraud risks by ensuring that each digital identity is unique, verifiable, and accessible only to the rightful owner through cryptographic proofs and decentralized identifiers.
Enabling trustworthy interactions: these identities provide a level of assurance through verifiable credentials, allowing reliable interactions where participants trust the integrity of the system rather than individual trust.
Providing global accessibility: regardless of location, on-chain identity helps populations with limited or no access to banking services participate in DeFi lending and financing opportunities.
Interoperability among platforms: allows seamless interoperability between dApps and blockchain networks, simplifying credit verification and granting users easy access to financial services such as loans and lines of credit.
Simplifying risk assessment: lenders can leverage a borrower's on-chain credit profile to more accurately assess the risk of default, resulting in fairer interest rates, better loan terms, and a lower likelihood of systemic failures in the credit system.
What is on-chain credit scoring?
On-chain credit scoring tracks and analyzes user interactions with on-chain applications, such as liquidity pools, lending platforms, and transaction volumes, to assess their creditworthiness. In decentralized credit markets, this revolutionary approach eliminates traditional credit scores, enabling more inclusive, data-driven lending decisions while ensuring transparency and security for both users and institutions.
A notable example of on-chain credit scoring is the Cred Score from the Cred Protocol, a credit data infrastructure that provides credit data from 30 lending protocols across 8 blockchains. With the Cred Score, platforms can verify the credit capacity of individual or multiple account addresses on a scale of 300 to 1,000.
A credit scoring system ultimately empowers decentralized platforms to assess risks and make lending decisions based on real data. It enables a more inclusive and fair financial ecosystem, far removed from outdated credit scoring models.
Why is on-chain undercollateralized credit important?
In TradFi, collateral is key. Borrowers pledge their assets to access credit, which is liquidated in case of default.
Both in the conventional scenario and in DeFi, overcollateralization is the norm. Borrowers are required to pledge an amount greater than the loan value, which restricts liquidity as borrowers cannot access the full potential of their capital, limiting their ability to invest, consume, and grow.
On-chain undercollateralized credit fills this gap, offering a more inclusive financial model, allowing loans based on factors like income, reputation, or alternative data sources, instead of requiring excessive collateral. It enables borrowers to unlock the future value of their income or receivables to meet immediate financial needs, fostering economic dynamism.
Huma Finance offers undercollateralized credit solutions, leveraging borrowers' income and receivables to assess credit capacity. This approach allows access to funding without the need for full collateral, making it more accessible for businesses and individuals.

Conclusion
On-chain credit eliminates the need for intermediaries and allows anyone with access to a blockchain network to participate in a global, borderless credit ecosystem. Borrowers can access funds without lengthy approval processes or rigorous credit checks, and lenders can deploy their assets into lending protocols, generating interest in a trustless environment.
Using blockchain, on-chain credit eliminates barriers that have long excluded underserved communities, offering access to capital based on decentralized data instead of outdated credit scores.
With greater capital efficiency and tailored loan solutions for its users, on-chain credit is essential to how we view and manage credit in the digital age.
