Where stealth addresses go next
Private receiving is the foundation. Here’s what it enables beyond basic payments.Upcoming use cases
Private prediction markets
Bet on outcomes without broadcasting your positions. Stealth addresses keep your participation invisible to other market participants and on-chain observers.Private payroll
Organizations pay contributors to stealth addresses. No employee can see what others earn. HR or finance holds the meta-addresses; the actual pay destinations are unique per period.Multi-chain expansion
SPECTER already supports Ethereum and Sui. Coming next:- Arbitrum - L2 stealth payments with lower gas costs
- Base - Same privacy guarantees on Coinbase’s L2
- Optimism - Expanding the rollup support
Cross-chain stealth transfers
Send from Ethereum, receive privately on Sui (or vice versa). The ML-KEM shared secret can derive valid addresses for any chain, making cross-chain private receiving possible.Private subscriptions
Recurring stealth payments where each period goes to a new address. The service provider can verify payment through the announcement system without revealing the subscriber’s identity on-chain.Technical roadmap
