Private payments. Cryptographic guarantees. No trust required.

​
Introduction

Ghost Link is a privacy-first payment routing layer built on Solana, powered by zero-knowledge proofs. It enables payments to be validated and settled without requiring users or applications to expose wallet addresses, balances, or funding structure as part of the payment flow. As blockchains scale, payments have become a major source of unnecessary information leakage. Today, initiating a payment often reveals far more context than is required to prove correctness and complete settlement. Ghost Link addresses this at the payment layer, without changing Solana’s execution model.

Private Payment Routing

Payments can be initiated without directly exposing sender wallet addresses as part of the payment process.

Multi-Wallet Private Funding

Payments can be funded from multiple wallets in a single flow, with zero-knowledge proofs verifying sufficiency and authorization without revealing the funding structure.

Zero-Knowledge Enforcement

All guarantees are enforced cryptographically using ZK proofs, not custodial or trust-based models.
Settlement remains fully on Solana. Only the minimum information required to finalize the payment is disclosed.

Why It Matters

Public execution does not require public intent.
As payments become a primary interface for users and businesses, reducing unnecessary exposure becomes a UX, security, and infrastructure requirement, not a niche feature. Ghost Link separates payment validity from wallet visibility, enabling more mature payment flows that scale with real-world usage.
