following:
- Determine which elliptic curve is being used to create public keys
- Determine how to encode all address types
- Find how transactions are constructed
- Decode any serialized transaction data, such as ABI-encoded calldata
Our development stack includes embedded C firmware and a TypeScript SDK. Ideal applicants can contribute to both by helping engineers implement specific crypto functionality.
- For every new network we want to add the following items:
- (SDK) Request public keys -> convert to addresses
- (SDK) Receive transaction bytes, instantiate transaction and validate against reference TypeScript utils, serialize transaction and send to Lattice1
- (Firmware) Implement new curve if needed (we already support SECP256K1, SECP256R1, ED25519, and BLS12-381)
- (Firmware) Calculate public keys and add option to GetPublicKeys route
- (Firmware) Decode and validate transaction bytes; render markdown-like text to represent the transaction in as human-readable a way as possible
- (Firmware) Sign on curve and return signature
