Why Senddy
Private payments that earn yield, cost less, and work everywhere.
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 |

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 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.
