Payment infrastructure that never sits between you and your money
Most crypto gateways collect into their own wallets and pay you out later. SwychRamp routes each payment straight to you.
Non-custodial by design
Payments settle to wallets you own. SwychRamp never holds merchant funds, so there is no platform balance to freeze, lose or wait for.
- Your keys, your wallet
- No withdrawal queue
- Nothing pooled with other merchants
Settlement in one transaction
Our payment contract splits every payment on-chain: your share and the platform fee move together, atomically, and anyone can verify it.
- Signed quotes, exact amounts
- Verifiable on a block explorer
- No end-of-day batch
Built for operations
Multiple merchants, team roles, approvals on sensitive changes and an audit trail — the controls finance and security teams ask for first.
- Roles and permissions
- Payout-address change protection
- Append-only audit log
From checkout to settled funds in four steps
Every payment follows the same auditable path, and every step can be checked on-chain.
Step 1
Create a payment
An invoice from the API, a shareable payment link, or the embedded widget. The crypto amount is locked when it is created.
Step 2
Customer pays
From any wallet — connect and approve in one tap, or scan a QR code and send to a unique deposit address.
Step 3
Split on-chain
The payment contract sends your share to your settlement wallet and the platform fee to ours, in the same transaction.
Step 4
You are notified
A signed webhook fires on confirmation and the payment appears in your dashboard, ready to reconcile.
Everything you need to accept, operate and integrate
One platform from the first payment link to thousands of API-driven invoices a day.
Accept
Every way your customers want to pay.
Hosted checkout
A mobile-ready payment page with live status, so you have nothing to build.
Payment links
Share a link by email or chat and get paid, no code required.

Pay with wallet
Customers connect MetaMask, TronLink and more, then approve in one tap.
QR and address payments
Every invoice has a unique deposit address and a QR code for any wallet.
Locked pricing
The crypto amount is fixed when the invoice is created, so volatility can’t shortchange you.

The controls a payments team runs on.

}'Security your risk team will sign off on
The safest balance is the one we never hold. Everything else is defence in depth.
No custody
Funds settle to merchant-owned wallets, so there is no pooled balance to attack.
Signed payment quotes
Every on-chain payment carries a server-signed quote with an expiry; tampered amounts are rejected by the contract.
Payout-address lock
Changing where you get paid needs 2FA, sends an email alert, and waits 24 hours.
Two-factor authentication
TOTP 2FA for every account, with session and device controls.
Role-based access
Platform and merchant-scoped roles keep every user to the least privilege they need.
Encryption at rest
Sensitive fields are encrypted separately from database access, and secrets live in a managed vault.
Signed webhooks
HMAC-SHA256 signatures let you verify every event really came from us.
Rate limiting
Per-key and per-IP limits protect your account and the API.
Append-only audit log
Security-relevant actions are recorded in a log that cannot be edited or deleted.
Address screening
Counterparties are checked against sanctions and risk lists.
