# Privily > The privacy financial appchain Privily is a self-custodial privacy neobank built on a zero-knowledge appchain for private multi-chain transactions and financial services. Privily is a self-custodial privacy neobank that lets users spend, transfer, invest, and earn across multiple blockchains from a single interface. It combines a zero-knowledge appchain with fintech-style account features, so financial activity stays private by default while users retain control of their own keys. The service targets both individual users seeking privacy over their financial habits and businesses seeking private treasury and payment infrastructure. The platform addresses the transparency of public blockchains, where balances and transaction histories are visible to anyone, by shielding activity unless a user chooses to disclose it. Its privacy protocol supports cross-chain transfers, swaps, and bridging, and it offers a software developer kit and an agent plugin so third parties can integrate private transactions into their own applications. Signatures use a post-quantum scheme intended to protect transactions against future cryptographic threats. The core privacy protocol and infrastructure layer are live, supporting private transfers, exchange, and payment rails for individuals and businesses. A neobank offering, including multi-currency accounts and payment cards, and a treasury management product for businesses are in development. Privily is used by individual crypto users seeking private transactions and by businesses and payment providers looking to add private financial flows to their operations. - Type: Company - Sector: Finance - Status: Active - Founded: 2025-04-01 - Profile: https://thegrid.id/profiles/privily ## Products - [Privily](https://thegrid.id/profiles/privily): Privily is a privacy-focused neobank appchain that lets individuals and businesses spend, transfer, invest, and earn across multiple blockchains from a single self-custodial account. It settles transactions on a Starknet-based appchain using zero-knowledge cryptography, shielding balances, spending habits, and transaction history unless the user chooses to disclose them. The platform offers private cross-chain transfers and swaps, programmable privacy with selective disclosure, and account abstraction so users interact without managing seed phrases directly. Additional announced services, including physical and virtual cards, multi-currency accounts, on and off ramps, and business treasury tools, extend the same account into broader banking-style functionality. (Neobank, Open Beta, Main Product) - [Privily Developer SDK & MCP Plugin](https://thegrid.id/profiles/privily): The Privily Developer SDK and MCP Plugin are integration tools that let developers and AI agents embed Privily's private, multi-chain payment operations into their own applications, backends, or agent workflows. The SDK exposes deposit, trade, send, request, and pay operations for apps and backends, while the MCP plugin exposes the same operations through the Model Context Protocol so AI agents can move funds on a user's behalf. Both surfaces build on the same underlying appchain account and privacy infrastructure as the main application. They are distributed as separate installable packages usable independently of the consumer app. (Developer Tooling, Open Beta) ## Links - [Main](https://privily.fi) - [Documentation](https://privily.gitbook.io/privily-doc) - [Blog](https://x.com/Privily_fi/articles) - [Twitter / X](https://x.com/Privily_fi) ## Legal This data is provided under two licensing models.
