How Does Crypto Lending Work? The Process Explained

Crypto lending represents an innovative financial activity within the digital asset ecosystem, allowing individuals to engage in borrowing and lending using cryptocurrencies. It functions much like traditional lending, where one party provides assets to another with the expectation of repayment and interest. This mechanism enables cryptocurrency holders to generate income from their digital assets that might otherwise remain idle, or access funds without liquidating their holdings. Instead of selling digital assets, which could incur tax implications or forfeit potential future gains, individuals can use their crypto as collateral to obtain a loan. This financial innovation leverages blockchain technology to facilitate transactions outside conventional systems.

Fundamental Principles of Crypto Lending

Crypto lending operates on several foundational concepts that define its structure and participant roles. The transaction involves a lender who provides digital assets and a borrower who receives them, agreeing to repay the principal amount along with an additional charge, known as interest. The principal refers to the initial amount of cryptocurrency or fiat currency borrowed. Lenders are motivated by the opportunity to earn passive income or “yield” on their digital holdings, transforming otherwise static assets into revenue-generating ones. This yield is typically paid in the same cryptocurrency lent or in stablecoins, which are digital assets pegged to a stable asset like the U.S. dollar.

Borrowers, on the other hand, seek to access liquidity without selling their cryptocurrency, often to fund other investments, cover expenses, or leverage positions. They use their digital assets as collateral, which is a form of security pledged to the lender to mitigate the risk of default. This collateral is typically valued more than the loan amount, a practice known as overcollateralization. For instance, a borrower might need to deposit $2,000 to $3,000 worth of cryptocurrency to secure a $1,000 loan. This excess collateral serves as a primary risk management strategy for lenders, protecting them against potential price volatility of the collateralized assets.

The Lending and Borrowing Process

For lenders, the process begins by depositing cryptocurrency assets into a chosen platform. These assets are often pooled and made available for borrowers. Once deposited, the lender’s assets start accruing interest, paid periodically based on platform terms.

For borrowers, the process starts with requesting a loan amount. Unlike traditional loans, this typically avoids lengthy applications or credit checks. The platform calculates required collateral based on the desired loan and a predetermined Loan-to-Value (LTV) ratio. The LTV ratio expresses the loan as a percentage of the collateral’s value; for example, a 50% LTV means a $5,000 loan requires $10,000 in collateral. The borrower pledges their cryptocurrency as collateral, transferring it to the platform.

Upon collateral confirmation, the loan is disbursed, often in fiat currency or stablecoins. The borrower repays the loan plus interest over a set timeframe, typically 12 months or less. Once repaid, the collateral is returned. If the collateral’s value decreases significantly, the borrower may need to deposit additional assets to maintain the LTV ratio and avoid liquidation.

Collateral Management and Interest Mechanics

Collateral, which secures the loan, is held in custodial wallets by centralized platforms or within smart contracts on decentralized protocols. For decentralized finance (DeFi) platforms, smart contracts automatically manage collateral, releasing it upon full repayment or initiating liquidation if terms are breached. These smart contracts ensure collateral is securely held and loan terms are programmatically enforced.

A liquidation threshold is a specific LTV ratio at which a borrower’s collateral may be automatically sold to cover the outstanding loan. This occurs if the collateral’s market value drops, causing the LTV to exceed the threshold. To ensure accurate, real-time collateral valuation, especially in decentralized environments, oracles are used. Oracles are data feeds providing smart contracts with external information, like current cryptocurrency prices, enabling precise LTV calculations and triggering liquidations.

Interest rates are determined by factors including market supply and demand, the platform’s business model, and overall market conditions. Rates are often algorithmically determined, fluctuating based on asset utilization in the lending pool, leading to variable interest rates. Some platforms offer fixed interest rates for a set loan term. Interest typically accrues continuously or block by block on the blockchain, paid to lenders according to the platform’s schedule, often in the same cryptocurrency lent.

Centralized Versus Decentralized Lending

Crypto lending is categorized into centralized (CeFi) and decentralized (DeFi) models, each with distinct frameworks. Centralized platforms operate like traditional financial institutions, taking custody of users’ funds and acting as intermediaries. Trust in CeFi relies on the entity’s ability to manage funds securely and adhere to terms, often incorporating Know Your Customer (KYC) and Anti-Money Laundering (AML) protocols.

In contrast, decentralized crypto lending operates on blockchain-based protocols using smart contracts. These self-executing contracts automate the lending and borrowing process, removing the need for a central intermediary. A key characteristic of DeFi lending is self-custody, where users retain control over their assets in their own wallets. All transactions and loan terms are transparently recorded on the blockchain, with execution governed by immutable code.
