Sword of Secrets is a multi-stage hardware Capture the Flag (CtF) challenge designed for hackers, tinkerers, and puzzle lovers who crave hands-on problem-solving. Housed in a sleek, keychain-sized board, this open-source adventure weaves together hardware hacking, cryptographic trickery, and low-level exploitation. As you delve through the stages, your mastery of embedded systems, RISC-V assembly code, datasheets, and creative debugging will be tested. Solving it means digging into both the schematics and the source code—and truly understanding them.

Crowd Supply is a store, distributor, and crowdfunding platform. Our mission is to bring original, useful, respectful hardware to life.
