# Qash > Turn your business into a stablecoin-native company Qash is a self-custodial business banking platform for crypto companies. It combines treasury management, payroll, invoicing, and payments with on-chain privacy. Qash, formerly known as Q3x, is a self-custodial business banking platform built for crypto companies. It unifies treasury management, payroll, invoicing, bill payments, and payment links into a single workspace, replacing the combination of multisig wallets, centralized exchanges, and spreadsheets that many crypto businesses rely on to manage their finances. The platform is aimed at founders, finance teams, and operators who need to pay employees and vendors across multiple chains while keeping balances and transaction history confidential. The platform addresses a gap in how crypto companies handle money: onchain transactions are typically visible to anyone inspecting a block explorer, exposing payroll amounts and counterparty details. Qash applies zero-knowledge proofs on a rollup network to keep treasury balances, payment amounts, and transaction histories confidential onchain, visible only to authorized team members, while users retain control of their own private keys. Multi-entity account organization and multisig-based approvals support teams operating across jurisdictions and currencies. Core offerings include multi-owner accounts, payroll and invoicing tools, bill payments, and chain-agnostic transfers, alongside a companion global account product that lets users hold and convert stablecoins pegged to fiat currencies and move funds between crypto and traditional bank rails. Additional features such as fiat on- and off-ramp, corporate card issuance, and yield on idle treasury are in active development. It is used by small and mid-sized crypto companies and distributed teams looking to consolidate their financial operations into one self-custodial platform. - Type: Project - Sector: Payments - Status: Active - Founded: 2025-02-01 - Profile: https://thegrid.id/profiles/qash ## Products - [Q3x Platform](https://thegrid.id/profiles/qash): Q3x Platform implemented AI-powered account management through Starknet's account abstraction, enabling natural language financial automation and customizable workflows.
