Turn Your Spare Change Into a Crypto Portfolio
Stack makes crypto investing effortless by automatically rounding up your everyday purchases and investing the spare change. Start building your digital asset portfolio with just your pocket change - no large commitments, no complex decisions, just smart, gradual growth.

Simple as Your Daily Coffee
Transform your everyday purchases into a growing crypto portfolio with three easy steps. Set it up once, then let your spare change do the work.
Connect Your Bank Account
Securely link your bank account or debit card through our encrypted connection. We use bank-level security to monitor your purchases for round-up opportunities, keeping your financial data completely protected.
Automatic Round-Ups Begin
Every purchase you make gets rounded up to the nearest dollar, and we invest that spare change into your chosen crypto portfolio. Buy coffee for $4.35? We'll invest the $0.65 difference automatically.
Watch Your Portfolio Grow
Track your investments in real-time with detailed analytics and insights. Your crypto grows gradually without you even thinking about it - no large payments, no complex decisions, just consistent wealth building.
Built for Modern Investors
Experience a new way to build wealth through cryptocurrency - designed for simplicity, security, and sustainable growth.
Your Keys, Your Crypto
Maintain complete ownership and control of your digital assets. Unlike traditional platforms, we never hold custody of your funds - your private keys remain exclusively yours, ensuring maximum security and autonomy over your investments.
Effortless Dollar-Cost Averaging
Automatically invest small amounts consistently over time, reducing the impact of market volatility. Your spare change from daily purchases builds a diversified crypto portfolio without the stress of timing the market.
Educational First Approach
Learn as you invest with guided insights, market analysis, and educational resources. We believe informed investing leads to better decisions, so we provide the knowledge and tools to help you understand your crypto journey.
