By Sydney, Australia, 17th November 2025, Radr, a Solana native privacy and payments infrastructure protocol, today announced the launch of ShadowPay, a private payment rail that brings true transaction privacy to the Solana and Bonk ecosystems. ShadowPay is designed to make private, programmable payments a first class primitive on Solana, so users, apps, and APIs do not have to choose between speed, low fees, and privacy.
Built as a token on the Bonk platform, led by community builder and founder @solportom, Radr sits inside one of the most active and culture driven communities on Solana. At the same time, ShadowPay is rooted in the Solana base layer, founded by Toly, and takes advantage of high throughput, low fees, and parallel execution to deliver a payment experience that feels instant and reliable.
As demand grows for faster, cheaper, and more private on-chain payments, ShadowPay introduces end to end encrypted payment flows, x402 style HTTP integrations, and developer first tooling to empower wallets, dApps, merchants, and AI agents across the Solana ecosystem. The objective is to make private payments as simple to integrate as a standard web checkout, while keeping on chain activity private from casual observers and analytics firms.
“We are building a future where Solana payments feel instant, invisible, and verifiable,” said Luke, Founder of Radr. “ShadowPay brings private x402 style payment rails on-chain without trusted middlemen. Our vision is to make privacy the default at the payment layer, not an afterthought, and this launch is a key milestone toward that. With Solana as the base layer and Bonk as our home community, we are focused on powering the future of payments.”
ShadowPay gives developers a straightforward way to offer privacy preserving payments without redesigning their entire stack. Through a familiar API, merchants and builders can create private paywalls, subscriptions, and usage based billing that settle on Solana while hiding sensitive payment details.
ShadowPay: Key Features
Built on Solana, in the Bonk ecosystem
Natively deployed on Solana and aligned with the Bonk platform led by @solportom, ShadowPay brings a privacy focused payment rail directly into an ecosystem that is already pushing consumer adoption forward.
True private payment rails
ShadowPay uses modern zero knowledge proofs and encrypted balances to hide senders, amounts, and flows, while keeping settlement verifiable on chain. Users and businesses can move value without exposing their complete history to counterparties, block explorers, or data aggregators.
x402 style HTTP integration
ShadowPay brings private payments directly into web style APIs and applications. Developers can plug private Solana payments into bots, marketplaces, creator tools, and AI agents that need to charge users programmatically, without exposing who paid what to whom.
Developer first SDKs
TypeScript and server side SDKs let developers accept private payments in a few lines of code, with support for common Solana wallets and frameworks. ShadowPay is designed to feel familiar to anyone who has integrated a traditional payment processor, while adding privacy and on-chain settlement.
Composable with Solana DeFi and Bonk
ShadowPay plugs into the broader Solana and Bonk DeFi stack, enabling private paywalls, subscriptions, tipping, gated access, and machine to machine payments. Builders can route flows through private rails while still connecting to the rest of Solana liquidity.
Under the hood, ShadowPay leverages modern zero knowledge cryptography, including Groth16 proofs, ElGamal style encryption, and bitmap nullifiers, to provide strong privacy guarantees while remaining efficient enough for real world payment flows.
Token and Ecosystem
Token name: RADR
Role in the ecosystem
RADR powers the Radr privacy stack and aligns incentives across ShadowPay, future zero knowledge products, and ecosystem integrations. It is designed to strengthen the sustainability of the protocol.
Use cases
Governance over protocol upgrades, routing incentives, and potential fee or discount mechanics for high volume users and partners.

About Radr
Radr is a Solana based privacy and payments infrastructure project that focuses on bringing private, programmable money to the mainstream. Built at the intersection of zero knowledge cryptography, payments, and the Bonk ecosystem, Radr is developing tools like ShadowPay to make it simple for apps, merchants, and AI agents to send and receive private payments on Solana.
With a mission to make financial privacy a default feature rather than a luxury, Radr is committed to building secure, scalable, and developer friendly infrastructure for the next generation of on-chain applications. By combining the performance of Solana with the culture and reach of Bonk, Radr aims to power the future of payments for everyday users and advanced on-chain systems.
