Making Bitcoin ready for inclusion into the OSS-Fuzz project should be fairly straightforward:

• Have a look at test_bitcoin_fuzzy.cpp and read the Bitcoin fuzzing documentation.
• Make test_bitcoin_fuzzy.cpp libFuzzer-friendly by implementing LLVMFuzzerTestOneInput. See the libFuzzer documentation for details.
• Create the three configuration files project.yaml, Dockerfile and build.sh as described in the OSS-Fuzz new project guide and submit an OSS-Fuzz pull request.

Today Google announced that they offer $1k to $20k in rewards for properly integrated project.

Have a nice vacation and enjoy the warm fuzzy feeling of having helped secure the Bitcoin network! :-)
