Certain aspects of the present disclosure provide techniques for building libraries for invoking smart contracts on a blockchain. The method generally includes compiling first source code in a first programming language defining a smart contract comprising a set of operations to be executed on a blockchain into bytecode for the smart contract based on one or more of information about a compiler to be used to compile the first source code or dependencies specified in the first source code. The bytecode for the smart contract is wrapped in second source code in a second programming language. The second source code is compiled into a portion of a library package through which the smart contract can be programmatically invoked, wherein the portion of the library package specifies version information associated with the smart contract. The library package is deployed for use with the blockchain.
