TL;DR: We built a WhatsApp bot that lets users supply/withdraw from Compound V3. MVP is live on Sepolia with verified transactions. Seeking community feedback before mainnet launch.

- Withdraw TX: Sepolia Transaction Hash: 0x68492bc21f... | Etherscan Sepolia
What We Built
A WhatsApp interface to Compound V3. Users text commands like:
- supply 10 USDC
- withdraw 5 USDC
- balance
- send 0.01 ETH to 0x…
Non-custodial. Encrypted key storage. Works on any phone.
Why This Matters
Compound’s interfaces assume desktop access, Web3 wallets, and DeFi familiarity.
African reality:
- 80%+ mobile-only users
- WhatsApp is the primary internet for many
- High crypto interest but DeFi feels inaccessible
Our approach: Meet users where they already are.
What’s Working (Sepolia)
- Non-custodial wallet creation
- Encrypted key storage (AES-256-GCM)
- Compound V3 supply/withdraw
- Balance checking (wallet + Compound positions)
- ETH and USDC transfers
Distribution Strategy
We’re not building infrastructure. We’re building distribution.
Target: Existing crypto holders in Africa who keep stablecoins on exchanges earning nothing, want yield but find DeFi intimidating, and already use WhatsApp daily.
Channels:
- African crypto communities (Telegram/WhatsApp groups)
- University blockchain clubs
- Local crypto influencers
- Partnerships with African exchanges for user education
Simple message: Earn 4-8% APY on your USDC via WhatsApp instead of 0% on exchanges.
What We Need
- Community feedback on the concept and UX
- Beta testers (especially in African markets)
- Guidance on mainnet deployment considerations
Team
Beacher - Cryptography and security (5+ years ZK/MPC)
Bunny - Backend and African market experience
Wisdom - Smart contract integration and DeFi tooling
We’re building this regardless of funding because we believe in financial inclusion. Would love the community’s thoughts.
