FREEBLOCK / SMART CONTRACTS
DeFi lending
platform development
We build protocols and interfaces for loans backed by digital assets. Positions, interest, price sources and liquidation rules are designed as one consistent system.
A custom protocol or an existing integration — chosen after reviewing your requirements.
01 / PRODUCT CAPABILITIES
A position users can understand
Users should see more than their loan amount: collateral value, repayment conditions and the margin before liquidation.
Pools and positions
Deposits, available liquidity, borrowing and repayments. Define accounting for lenders and borrowers.
Collateral and debt
Collateral rules, interest accrual and limits. Show how a proposed operation changes the position.
Risk controls
Price sources, liquidation thresholds and operation limits. Plan for unavailable or stale data.
02 / DELIVERY SCOPE
Model first, contracts second
Before implementation, agree on assets, economic parameters and exceptional scenarios. They shape both the code and interface.
-
Protocol model
Define markets, collateral assets, interest, limits and management authorities. Model insufficient liquidity.
-
Contracts and oracles
Implement deposits, borrowing, repayment and liquidation. Validate prices, calculation precision and data freshness.
-
User dashboard
Positions, history, operation previews and liquidation-risk explanations. Connect wallets and indexing.
-
Test launch
Test invariants and stress scenarios. Prepare monitoring, initial limits and materials for independent auditing.
03 / ARCHITECTURE
Conditions that shape the protocol
- Custom protocol or integration
- Compare a new implementation with an existing protocol integration. Consider restrictions, dependencies and control over parameters.
- Prices and liquidations
- Choose price sources, freshness rules and thresholds for each asset. Check sharp price movements and failed liquidation attempts.
- Governance and launch
- Agree on roles, limits, operation pauses and parameter changes. Launching the software does not automatically supply liquidity.

04 / FREEBLOCK EXPERIENCE
Real projects behind the work
Tokensale demonstrates related DeFi experience: wallets, a user dashboard, Uniswap and PancakeSwap integrations, liquidity pools, farming and staking. It is not presented as a delivered lending protocol.

Test beyond the normal journey
Independent auditing and risk modelling are planned separately. Software development cannot guarantee returns or the preservation of asset value.
- Accounting invariants, interest accrual and rounding.
- Stale prices, sudden market changes and oracle outages.
- Liquidations, repayments and insufficient liquidity.
- Parameter changes, team permissions and event monitoring.
06 / COST AND TIMING
An estimate for your scope
First we define the initial release and its dependencies. Then we estimate the delivery phases and identify external costs separately.
Product model
Markets, assets, interest and collateral rules.
Implementation
Custom protocol or integration, interface and indexing.
Validation and launch
Modelling, tests, independent auditing and monitoring.

08 / FAQ
Before we start
What is a DeFi lending platform?
It is a product for supplying and borrowing assets through smart contracts. In a collateralised model, contracts account for assets, debt, interest and liquidation conditions.
Can you integrate an existing protocol?
Yes. First we check whether it supports the required networks, assets and workflows. Then we estimate the integration and explain restrictions and external dependencies.
How is the borrowing limit determined?
It depends on collateral valuation and agreed risk parameters. These rules are defined before development and checked in calculations, tests and the user interface.
Why does the platform need an oracle?
Operations that depend on asset value need a price source. We validate data freshness as well as the price and define behaviour when the source fails.
Is an independent audit included?
Its scope and provider are agreed separately. We prepare code, tests and architecture documentation; a launch with real funds is planned around the assessment results.
How can I get a development estimate?
Describe the networks, assets, lending model and preference for a custom protocol or integration. We will separate research, implementation and validation phases.
FREEBLOCK / LET’S TALK
Let’s discuss your lending model
Which assets and networks do you need? Who supplies liquidity? Do you want a custom protocol or an integration? Which lending rules are already defined?
