Key highlights:
Assembly backends for x64 (MASM/GAS, BMI2/ADX), ARM64, RISC-V SIMD: AVX2/AVX-512 batch operations GPU: CUDA (4.63M kG/s), OpenCL, ROCm/HIP Constant-time layer with separate namespace (no runtime flag switching) Full protocol stack: ECDSA, Schnorr BIP-340, MuSig2, FROST, Adaptor sigs, Pedersen commitments Complete Bitcoin support: Taproot, Silent Payments, BIP-32/44, all address types 27+ cryptocurrency address generation with auto-dispatch Custom generator/curve context support Runs on: x64, ARM64, RISC-V, ESP32, STM32, WASM, iOS, Android 200+ tests, fuzz harnesses Design philosophy: hot paths are allocation-free, branchless where possible, with explicit buffers and fixed-size POD types. No exceptions/RTTI/virtual calls in compute paths
