The repository contains implementation code for all ECPDKSAP protocol versions.
All protocol variations are implemented in Go programming language and use consensys/gnark-crypto library.
Forked version: 0x3327/gnark-crypto containing custom function implementations needed by ECPDKSAP protocols.
Smart contracts are developed using Foundry framework and follow the EIP-5564 standard.
The project's dir. structure is as following:
./impl: Off-chain protocol code (used by sender and recipient to generate/scan data)./sc: On-chain contracts (used for sender - recipient "communication")./backend: Event indexers, API modules, ...
