Balance-Private

Balances proven by signature — never exposed in transit

Every transaction is signed by both parties. Every signature covers the balance transition. Every entry proves the one before it.
The chain verifies itself.

The Self-Verifying Chain

Every transaction is cryptographically chained — each entry's signature covers the balance transition, linking it to the previous entry. No consensus. No mining. The chain verifies itself.

Blockless Sequencing · 15,000+ TPS
Multi-Scheme Dual Signatures

Both sender and receiver sign every transaction. Supports EVM ECDSA (Ethereum), Ed25519 (Solana, Stellar, NEAR, Cardano), and ML-DSA-65 (NIST FIPS 204). Neither signature can be forged — not even by quantum computers.

Multi-Chain · Post-Quantum · Non-Repudiable
Balance Privacy

Balances are embedded in the signature but never transmitted. The server independently reconstructs and verifies. Your balance proves itself without being exposed.

Server-Side Reconstruction · Zero Balance Exposure

The Tadah Gift Card Maturity Journey

Trace your coin's lifecycle as it advances from a local Store Gift Card (DAH) to a Network Gift Card (DAHYM), and settles as a Universal Stablecoin (DAHLOR).

💎 Why the DAH Ecosystem Outperforms Legacy Universal Cards (Visa/Mastercard)

🏪
0% Activation Fee

Universal prepaid cards charge **$3.95 - $6.95** instantly at purchase. DAH store cards issue at **100% face value** with zero upfront activation losses.

🏙️
Merchant Flywheel

Bypasses the **3% interchange tax** of legacy cards. Merchants settle peer-to-peer, routing transaction savings back to you as **5% cashback or discount bonuses**.

🌐
Yield-Bearing Float

Visa cards sit as "dead float" in bank accounts. DAHLOR balances can earn **4% - 5% APY** while unspent—turning standard gift cards into wealth-generating assets.

🔒
Quantum Security

Protects against rack barcode theft and card copying. Secured by post-quantum **ML-DSA-65** dual-signatures and complete balance privacy.
