Abstract and Easy-to-Use Cryptographic Infrastructure Library
We created the big wallet Cryptography Basic Algorithm Library suite in C++ to make it easier to develop upper-layer cryptographic protocols, which includes the Big Number Computation Library, the Abstract Elliptic Curve Algorithm Library, the Homomorphic Encryption Algorithm Library, the Secret Sharing Scheme Algorithm Library, and the Zero-Knowledge Proof Protocol Algorithm Library.
TSS-RSA Protocol
TSS-RSA is a threshold signature algorithm for RSA that we've implemented. It has capabilities for generating key shards, signing by distributed keys,verifying signature shards, combining and verifying shards' signatures.To propel the algorithm's use cases in the Arweave ecosystem, we have been actively collaborating with the project’s developers.
MetaMask Snap & Hardware-Based Two-Party MPC Wallet POC
Big Wallet has collaborated with MetaMask and Keystone to implement a two-party MPC wallet POC between MetaMask Snap and Keystone. The POC demonstrates functions such as distributed key generation, distributed signing, transfer of assets, backup & import of key shards.

MPC Private Key Derivation Protocol
It allows for a group of MPC private key shards to be used for managing multiple wallets and supports multi-party private key derivation, i.e. the derivation of sub-private key shards and corresponding public keys from a private key shard group in accordance with BIP44. Currently, there's support for MPC-ECDSA, MPC-ED25519, and MPC-BLS protocol derivation algorithms.

Garbled-Circuit-Based Two-Party HMAC Signature Protocol
It supports two-party protocols for HMAC-SHA256, HMAC-SHA384, and HMAC-SHA512, as well as key shard generation, distributed key refresh, and distributed signatures.
