Module syscalls 

Minimal syscall shims exposed through Hopper Runtime.

Hopper-owned crates use this module instead of depending on external SDK syscall paths.

Functions

sol_alt_bn128_compression^⚠

Run a BN254 / alt_bn128 compression operation.

sol_alt_bn128_group_op^⚠

Run a BN254 / alt_bn128 group operation.
