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.

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 from your bank, send by username, spend with a card. Privacy that just works.
