Description

OffChain Wallet enables secure blockchain transactions through offline USSD and SMS, connecting unbanked users to Web3 without smartphones or internet. It ensures ethical inclusion through encrypted transaction proofs stored locally until connectivity resumes, maintaining privacy and trust in underserved areas.

Detailed Idea

Alignment with DF goals (BGI, Platform growth, community)

Problem description

Blockchain adoption is restricted in offline rural communities due to infrastructure deficits. Wallet solutions require full connectivity, leaving millions unable to transact safely. This deepens inequality, forcing dependence on insecure informal financial systems.

Proposed Solutions

OffChain Wallet utilizes encrypted offline transaction signing. Users initiate transfers via USSD or SMS, with proofs automatically broadcast when connected. Smart contracts reconcile pending transactions securely. This model maintains privacy, transparency, and equitable blockchain participation for offline populations.
