The free guide will walk you through your first steps, from buying your first cryptocurrencies to creating a software wallet and making a transaction on the blockchain. It is available by filling out the form below.
To delve deeper into these concepts, gain a thorough understanding of how the monetary system and Bitcoin work, and develop a more comprehensive grasp of the tools, finance, and legal constraints, we invite you to explore the BSM program .
It includes detailed video tutorials on centralized exchanges, software wallets, hardware wallets, and essential best practices. The program can be accessed via the header or the link above.
The entire system is managed by smart contracts that automate each transaction , from granting the loan to distributing interest and repayment. This system allows anyone to become a lender or borrower without intermediaries.
The two models of lending platforms
- Decentralized platforms (DeFi): operate directly on the blockchain via decentralized applications ( dApp ) and smart contracts . Examples: Aave , Compound, Morpho, Angle Protocol.
- Centralized platforms : managed by a company that acts as an intermediary. Examples: Coinbase , Nexo, Bitvavo, Binance .
What are the advantages of "crypto lending"?
- Generate interest on your unused assets without selling them.
- Access cash quickly without relinquishing ownership of your assets .
- Automated process, without human intervention, thanks to smart contracts .
- No mandatory identity verification on most decentralized platforms .
- Possibility of staking and participation in other products on the same platform.

What are the risks of "crypto lending"?
The main risks associated with lending and borrowing in cryptocurrencies:

How can "crypto lending" be used in practice?
Step 1: Choose a decentralized wallet
To interact with lending and borrowing platforms , you need to use a Web3 wallet
There are two categories: software portfolios and hardware portfolios.
Software wallets are simpler and faster to use but less protective; hardware wallets protect your private keys in a dedicated device but involve lower accessibility and execution speed.
If you're interested in purchasing a hardware wallet, we're affiliated with Ledger , the world leader in this field. Their wallets allow you to store your assets offline while interacting with decentralized applications Ledger 's main advantages are:
- Physical protection of private keys using a secure chip.
- Compatible with most blockchains and dApp .
- Management of multiple assets and direct access to platforms to generate interest .
For more technical details on Ledger , we invite you to read our detailed article on which Ledger to choose.
To better understand the different tools, what they entail and how to use them in practice, you have access to the BSM program in the header.
Step 2: Connect to a lending platform
After setting up your decentralized wallet , connect to a platform of your choice. The best lending/borrowing platforms offer a user-friendly interface and competitive rates.
- Access the platform dApp or website .
- Connect your wallet .
- Choose the type of loan (lending or borrowing cryptocurrencies ).
Step 3: Lending or borrowing cryptocurrencies
- To lend, select the asset to deposit and the amount.
- To borrow , choose the asset to receive and deposit sufficient collateral (often greater than the value borrowed).
- Confirm the transaction via your decentralized wallet .
Interest rates and loan terms are displayed before confirmation. You can track your balances and repay at any time, subject to the lending platform .
What types of loans are available on crypto lending platforms?
- Over-collateralized loan : the borrower must deposit more value as collateral than the loan amount.
- Sub-collateralized lending : reserved for certain users or protocols, riskier.
- Flash loan : This is a cryptocurrency loan where the borrowed amount must be repaid in the same transaction. Specifically, all the steps (borrowing, using the funds for operations like arbitrage, and then repayment with fees) are programmed to execute sequentially, in a matter of seconds. If the repayment does not occur within this same transaction, the entire operation is automatically canceled, as if nothing had happened.
Most platforms operate with over-collateralized loans to limit the risk of default.
How do lending platforms set interest rates?
Interest rates are generally dynamic, determined by supply and demand for each asset :
- If many lenders deposit an asset , the rate falls.
- If the demand for borrowing increases, the rate rises.
- Some protocols offer fixed rates , but most are variable.
The best lending and borrowing platforms display real-time interest rates for each asset and automatically adjust according to market conditions.
