Developers on the Solana network have revealed the launch of Confidential Balances on the mainnet, presenting a new token standard that enables encrypted transfers and balances.
The Confidential Balances token extensions are now operational on the Solana (SOL) mainnet, shortly after the introduction of “token extensions.” With this mainnet support, users can utilize zero-knowledge proofs for privacy-centric transactions and features.
Quicknode, which announced the deployment on Solana, highlighted that this achievement brings ZK-enabled token transfers and concealed balances, among other benefits.
“With the launch of Confidential Balances on Solana, developers can now implement encrypted token balances and transfer amounts while preserving Solana’s speed advantages,” the platform stated on X.
The developer community can now create privacy-oriented merchant payment solutions, payroll systems, institutional transfer tools, and consumer applications, all while taking advantage of Solana’s rapid capabilities.
Quicknode mentioned that the stablecoin project Agora is the first initiative to utilize confidential transfers for its tokens. Agora Dollar, which focuses on real-world use cases, is now operational on Solana, providing its institutional-grade discreet payroll services to users.
In contrast to traditional blockchains, confidential balances empower users to manage their financial data on-chain. The technology encrypts token balances and transfers, ensuring privacy. Consequently, while user accounts and transactions remain visible, the actual balances or asset values transferred are kept confidential.
A recent blog post emphasized that confidential balances incorporate two main features – confidential transfer and confidential transfer fee.
The first feature conceals token movements, while the second ensures the confidentiality of transaction fees. Furthermore, Solana developers are exploring an additional feature called “Confidential MintBurn,” which would allow for private creation and destruction of tokens.
Ilan Gitter, the lead engineer for payments and commerce at Solana Foundation, shared insights via X:
“Confidential balances can not only provide privacy for Solana but also facilitate asset flows where balance confidentiality is crucial, such as in institutional payments. The development experience is still a bit rough, but if there’s one thing Solana excels at, it’s overcoming challenges to create impressive solutions,”
