Sigmadex is built using the following libraries, frameworks and languages. Documentation is available for its core technical stack.

The InterPlanetary File System is a protocol and peer-to-peer network for storing and sharing data in a distributed file system. IPFS uses content-addressing to uniquely identify each file in a global namespace connecting all computing devices.
Rust is a multi-paradigm programming language designed for performance and safety, especially safe concurrency. Rust is syntactically similar to C++, but can guarantee memory safety by using a borrow checker to validate references.
Substrate is the backbone that powers Polkadot, a next generation, heterogeneous, multi-chain network. Most of the blockchains in the Polkadot ecosystem are also built on Substrate.
Solidity is a statically-typed curly-braces programming language designed for developing smart contracts that run on EVM based blockchains such as Ethereum, Binance Smart Chain and Polygon.
