Atomic execution: All operations happen in one transaction. If any step fails, the entire payment reverts. Buyer funds are never at risk.
Built for Web3, Designed for Simplicity
Enterprise-grade payment infrastructure on Solana. The Stripe model, but for on-chain communities.
Instant Settlement
No 3-day holds. Funds arrive in your wallet the moment the transaction confirms on Solana's 400ms block time. Real-time settlement, not promises.
Traditional payment processors hold funds for 3-7 days. Qantara settles instantly because payments are on-chain and final. Lower your cost of capital and eliminate liquidity constraints.
Non-Custodial Architecture
You control your keys, wallets, and configurations. We never touch your funds. No intermediary custody, no approval required for withdrawals.
Unlike centralized processors, Qantara never holds your funds. Every payout goes directly to your configured wallet address. Complete sovereignty over your payment infrastructure.
Deflationary Tokenomics
Every payment reduces token supply. Transparent, verifiable, automatic. Create sustainable value for your community token holders.
Each transaction automatically burns a configurable percentage of acquired tokens. Watch your token supply decrease with every sale. Commerce-driven deflation, not speculation.
Zero Chargebacks
On-chain payments are final. Say goodbye to fraud, disputes, and chargeback fees. Payments are as final as cash.
Blockchain transactions are irreversible. Once confirmed, funds are yours. No chargebacks, no disputes, no fraud. Reduce operational overhead and risk.

Solution: Accept payments for your services, products, or subscriptions. Every payment automatically buys back and burns your token. Watch your chart move with every sale as supply decreases and demand increases.
A Solana developer offers consulting services. Clients pay in USDC. 20% automatically buys back and burns the project token. Every client payment creates measurable deflationary pressure, giving holders a reason to stay.
Business That Adds Value to Your Community
Your community has a token, but it's struggling. You run a business and want every sale to strengthen your community—not just generate revenue. You need payments that create value for holders.
Solution: Turn every sale into community value. Configure your payment split so a portion automatically buys back and burns your community token. Your business success becomes your token's success.
