Building Smart Contracts on Libre

Libre meets developers where they are at. There is no need to learn a new language as Libre supports building in almost all modern and popular programming languages including C++, Typescript, Rust, Go, and Python.

Full Turing-Complete WASM Smart Contracts

Libre's smart contract layer is built on WebAssembly (WASM), providing a full Turing-complete environment that enables developers to create complex, sophisticated applications. This is a significant advantage over other Bitcoin-focused platforms which typically offer limited or no smart contract capabilities.

With Libre's WASM implementation:

Execute any computable function or logic
Develop complex financial applications
Create custom token standards
Build decentralized applications with rich functionality
Implement advanced cryptographic operations

Interacting with Bitcoin on Libre

One of Libre's most powerful features is the ability to interact with Bitcoin in two distinct ways through smart contracts:

1. Unwrapped BTC (Vault System)

Smart contracts can interact with Bitcoin held in the CrossLink vault system without requiring the BTC to be wrapped as a token. This enables:

Direct collateralization of BTC for lending applications
Automated vault management
Liquidation protection mechanisms
Real-time BTC collateral monitoring
Withdrawal approval logic based on complex conditions

2. Wrapped BTC (Fast BTC)

Smart contracts can also interact with BTC that has been wrapped as a token on Libre, providing:

Faster transaction processing
Lower fees for frequent operations
Simplified integration with other DeFi applications
Token swaps and trading functionality
Advanced programmable escrow mechanisms

This dual approach gives developers unprecedented flexibility in how they incorporate Bitcoin into their applications, choosing the method that best suits their specific use case.

Development Tools

There are online several online IDEs you can use to build on Libre Chain - so you do not have to install any software locally to get started.

For example, any Antelope-based tools will work with Libre, for example:
