🧩 The Problem

Every Solana wallet address is fully public. The moment you share your address to receive payment, you hand the sender — and anyone with internet access — a permanent window into your entire financial life.

What gets exposed	Who can see it
Every payment you received	Anyone with your address
Who paid you and how much	The sender + blockchain explorers
Your current and historical balance	The public
Every wallet you ever interacted with	Anyone

This affects real people, every day:

🏢 Businesses accepting crypto — competitors can watch revenue in real time
🏠 Individuals applying for loans or visas — they must expose their entire history to prove some income
🎯 Fundraisers — every donor can see the full contributor list and amounts

⚠️ The root cause: Solana is a public ledger by design. There is no native privacy primitive for payments. Existing workarounds mixing services, centralized relayers are legally risky, require third-party trust, or are impractical for everyday users.

VeilMe fixes this at the protocol level - zero compromises on self-custody or decentralisation.

VeilMe is built on two complementary protocols:

Umbra is an on-chain stealth address protocol on Solana mainnet.
