## The Problem

Every payment you make creates a permanent, visible record. Your bank sells your transaction data to advertisers. Venmo broadcasts your payments in a public feed. Your credit card statement reveals your habits to anyone with access.

Financial privacy should be the default, not the exception.

## The Senddy Difference

Senddy is the first payment platform that gives you **real privacy**, **real yield**, and **real spending power** — all in one account.

### Privacy that actually works

Every transaction on Senddy is verified using zero-knowledge proofs. This means the network can confirm your payment is valid without knowing who sent it, who received it, or how much was transferred.

- Your balance is invisible to everyone but you
- Your transaction history is cryptographically hidden
- Even Senddy cannot see your activity
- No data is sold, shared, or exposed — ever

### Earn on every dollar

Your Senddy balance earns yield automatically from DeFi protocols. No staking, no lockups, no management required.

| | Traditional Bank | Senddy |
|---|---|---|
| **APY** | 0.01% | 3-4% |
| **On $10,000** | $1/year | $300-400/year |
| **Lockup** | None | None |
| **Compounding** | Monthly | Continuous |

### Spend online with a prepaid card

- **Senddy Prepaid Card** — Non-reloadable U.S. virtual card
- **Private funding** — Create a $5–$1,000 card from your private USDC balance
- **Online checkout** — Use the supplied card details at supported U.S. merchants
- **Pay by username** — Free instant transfers to any Senddy user

## How Senddy compares

| Feature | Traditional Bank | Venmo | Senddy |
|---|---|---|---|
| **Earns Interest** | 0.01% | 0% | **3-4%** |
| **Transaction Privacy** | Bank sees all | Public feed | **Only you** |
| **International Fees** | $25-50 | 3% | **Free** |
| **Sells Your Data** | Yes | Yes | **Can't** |
| **Settlement Speed** | 1-3 days | Instant | **Instant** |

## For Developers: Cheap and instant privacy

Senddy is also a payments infrastructure platform. If you're building an app that handles money, Senddy gives you:

- **0% transaction fee** vs traditional Stablecoin infra 0.5% + $0.30*
- **Instant settlement** — no 2-day hold
- **Privacy by default** — customer data never touches your servers
- **Stripe-like DX** — React hooks, REST APIs, webhooks

See the [Developer Overview](/docs/developers) for integration details.

## Built for scale

Senddy runs on Base, a Layer 2 network built on Ethereum by Coinbase. This means:

- **Sub-second finality** — transactions confirm almost instantly
- **Negligible gas costs** — fees are fractions of a cent
- **Ethereum security** — inherits the security of the most battle-tested blockchain
- **Institutional backing** — Base is operated by Coinbase, a publicly traded company

The zero-knowledge proof system processes client-side in 2-5 seconds, and all transactions are gasless — users never need to hold ETH or understand blockchain mechanics.

## What Senddy is not

- **Not a bank.** Senddy is a non-custodial payment platform. Your funds are held in audited smart contracts, not a bank account.
- **Not crypto.** You hold digital dollars (USDC), not volatile tokens. The crypto is the engine, not the experience.
- **Not complicated.** Fund your balance, send by username, or create a prepaid card for supported online checkout.
