This library offers utilities for developing verifiable client executables that may run on top of Fault Proof Virtual Machine targets.

  • The alloc_heap macro allows for statically allocating a heap of a certain size, and all client programs will need to run it if they require heap allocation. The alloc crate can be used for programs targeting any FPVM, but is optional.
  • The io module provides a high-level safe interface over the read, write, and exit syscalls on all available FPVM targets. While the FPVMs support a larger set of Linux syscalls, this crate looks to support the bare-minimum required for client programs to communicate back and forth with the host and exit properly. If a consumer of the library would like to extend the functionality of the ClientIO, an extension trait can be made for the ClientIO type in the io module.
