OyaCheck

OyaCheck is a digital safety assistant that helps Nigerians identify warning signs in suspicious websites, phishing links and forwarded messages before sharing sensitive information or making payments.

Users can paste URLs or messages and receive understandable analysis in English or Nigerian Pidgin. OyaCheck identifies misleading domains, suspicious URL structures and common social-engineering patterns, while providing practical safety recommendations. It also offers optional voice controls with browser-dependent support.

Built for the Build with buy track, OyaCheck integrates with an independent paid browser service to retrieve official cybersecurity advisory evidence. On Celo Mainnet, its dedicated buy payment wallet successfully paid 0.003606 native USDC for a browser investigation that retrieved an NCC advisory concerning phishing sites impersonating Nigeria's device-verification portal.
