Privacy-First Burner Wallets(Security Onchain)
The problem GhostWallet solves
Most on-chain activities are traceable, linking a user’s wallet history and identity across dApps. Even simple transfers or testing smart contracts leave permanent on-chain footprints that compromise privacy.
Ghost Wallet solves this by creating temporary, unlinkable burner wallets that use zero-knowledge proofs, privacy pools, and paymaster-sponsored transactions to completely detach a user’s main wallet from their on-chain activities.
In short: it lets users transact, test, and explore the blockchain without exposing their main wallet identity or paying gas directly.
Challenges we ran into
- Integration complexity — tying together Account Abstraction (ERC-4337), Paymaster logic, and privacy pools required deep coordination across contracts.
2. Deployment hurdles on Hardhat — managing multiple contracts and ensuring deterministic deployment addresses (for factory + wallets) was challenging.
3. ZK proof setup — ensuring proofs were lightweight enough for frontend generation while still secure took significant tuning.
4. Session management — maintaining ephemeral key validity across both frontend memory and smart contracts.

What is your product’s unique value proposition?
Ghost Wallet uniquely merges privacy, usability, and security into one burner wallet system.
Unlike typical privacy tools that are complex or require trusted mixers, Ghost Wallet:
• Uses Account Abstraction to make every action gasless and smooth.
• Employs zero-knowledge proofs to ensure no link between main and burner wallets.
• Keeps all keys client-side — full user control, zero backend custody.
• Allows temporary, self-destructible wallets for maximum anonymity.
Essentially, it’s the first wallet that’s both fully private and user-friendly.
Who is your target customer?
• Developers testing dApps or deploying smart contracts. • Privacy-focused DeFi users who want unlinkable wallets. • Hackathon and event organizers needing temporary wallets for participants. • Blockchain explorers who don’t want their activities tied to one public address. • Users in restrictive environments who need privacy for financial interactions.
Who are your closest competitors and how are you different?
Competitors:
• Tornado Cash / Railgun — provide privacy but not temporary wallets or session-based control.
• Safe (Gnosis Safe) — allows multi-sig and session keys but not anonymity or privacy.
• Burner Wallet 2.0 — focuses on UX, not privacy or unlinkability.
Our Difference:
• Ghost Wallet combines privacy + session-based wallets + gas abstraction.
• Unlike mixers, no central custody or fund pooling risk.
• Unlike typical AA wallets, ZK integration ensures unlinkability.
• Fully client-side key management and no recovery = maximum privacy.
What is your distribution strategy and why?
Strategy:
1. Developer adoption first:
• Launch SDK and demo dApp integrations (allowing others to plug in Ghost Wallet easily).
2. Hackathon and Web3 event distribution:
• Partner with organizers to provide burner wallets for participants.
3. Privacy-first communities:
• Collaborate with DAOs, DeFi projects, and privacy networks.
4. Content and social education:
• Tutorials, GitHub templates, and short explainer videos on using privacy-enabled AA wallets.
Why:
Because developer and community adoption drives credibility in Web3. The more builders integrate Ghost Wallet into their dApps, the faster it becomes a standard for private, gasless sessions.
