Get paid in stablecoins, straight to your wallet.
Sadaya gives every order its own smart contract. It can only send 99% to you and 1% to us, so nobody can hold or redirect your money, not even Sadaya. USDT, USDC and more on Ethereum and BNB Chain.

How it works
Three steps, and the money never stops at Sadaya.
You charge the way that suits your business. The payment goes to a contract that exists only for that order, and the contract pays you.
Create the order
From your server with the API, from a payment link you share by chat or email, or with the checkout embedded in your store.
Your customer pays
Every order has its own address and QR code. The checkout shows the payment as it arrives and confirms it on-chain.
You get paid
The order's contract splits the payment: 99% to your wallet and 1% fee. Instantly, daily, weekly or monthly, as you choose.
Everything you need to charge
Built for businesses that sell for real.
From the first test payment to your monthly statement, with your brand on everything your customer sees.
A contract per order
What a customer sends can only go to your wallet and the fee. Nobody can redirect it.
Payouts on your schedule
Instant, daily, weekly, monthly or manual, in batches, with a statement for every payout.
Payment links
Products and links you share anywhere, for teams that don't have a developer.
Embedded checkout
Customers pay without leaving your store, with a script pinned by its integrity hash.
API, webhooks and libraries
A REST API, signed webhooks, and Node and PHP libraries that verify every order's address.
Refunds
Your customer leaves their wallet through a link, you refund from yours, and Sadaya verifies it on-chain.
Wrong network, wrong token
Payments sent on another network or with another token stay at the order's address, ready to recover.
Payer screening
Every payer is checked against sanctions lists and AML risk before the money reaches your wallet.
Your team, safely
Roles for owners, finance and support, two-step verification and a tamper-evident activity log.
Security
Built so that we can't touch your money.
Sadaya never holds a balance for you. The rules live in code on a public blockchain, where you can check them yourself.
No custody
Every payment lands in a contract made for that order, not in a Sadaya account.
Two destinations, sealed
The contract only knows your wallet and the fee. Changing your payout wallet needs approval and a 48-hour wait.
You get paid, whatever happens
For 30 days only Sadaya can release a payment, so risky funds can be held. After that anyone can trigger your payout, even if Sadaya were gone.
Every cent on the record
Each payment, payout and fee has a public transaction hash you can verify on any block explorer.

Questions
Frequently asked questions
Does Sadaya hold my funds?
No. Each payment goes to a smart contract made for that order, and it can only pay your wallet and the 1% fee. Sadaya never takes custody of your money.
Which coins and networks can my customers pay with?
USDT and USDC on Ethereum and BNB Chain, plus DAI, PYUSD, USDG and FDUSD, and ETH or BNB for prices set in dollars, at a rate locked for up to 60 minutes.
How fast do I get paid?
As soon as the payment is confirmed on-chain, on the schedule you choose: instantly, daily, weekly or monthly.
What if a customer pays on the wrong network or with the wrong token?
The money stays at the order's own address, never mixed with anything else. From $200 you can recover it for a 10% fee, capped at $500.
How much does it cost?
1% per payment. No setup fees, no monthly fees, and the network fees of your payouts are included.
Do I need a developer?
No. Payment links and products work without code. With a developer you get the API, signed webhooks, the embedded checkout and libraries for Node and PHP.
