libblsct-bindings

libblsct-bindings provides multi-language bindings for navio-core's BLS Confidential Transactions (BLSCT) library.

BLSCT enables confidential transactions on the Navio blockchain - amounts and recipient addresses are hidden on-chain using BLS12-381 elliptic curve cryptography and range proofs. These bindings expose the key derivation, sub-address generation, address encoding, and transaction construction primitives needed to build wallets and integrations in your language of choice.

Requirements

All language bindings require the native libblsct shared library to be available on your system:

• Linux: libblsct.so
• macOS: libblsct.dylib
• Windows: blsct.dll

See navio-core for build instructions.

Contributing

Contributions are welcome. Each language binding lives under ffi/<lang>/ and has its own README with build and test instructions. Before submitting a PR:

• Run the test suite for the language you changed
• Ensure the SWIG interface files (blsct.i) stay in sync across Python and TypeScript (checked by CI)
• Follow the existing code style for that language
