SRD Exchange supports two INR payment methods: UPI (Unified Payments Interface) and CDM (Cash Deposit Machine). Both methods allow you to trade USDT for INR directly with other users, without involving any exchange-managed bank account. The right choice depends on your priorities — UPI offers instant digital convenience, while CDM provides maximum privacy and eliminates any risk of bank account freeze. Sellers specify which methods they accept when listing, so you can filter orders by the method that suits you.
How UPI works
UPI is a real-time digital payments system operated by the National Payments Corporation of India (NPCI). When you pay via UPI on SRD Exchange, you transfer INR directly from your bank account to the seller’s UPI ID using any compatible app.Compatible apps
- Google Pay
- PhonePe
- Paytm
- BHIM
- Any UPI-enabled banking app
How to pay
- The seller’s UPI ID is displayed on the trade page after you confirm the order.
- Open your UPI app, enter the UPI ID, and enter the exact INR amount shown on the trade page.
- Complete the transfer and return to the platform to mark payment as sent.
Pros
- Instant transfer — funds typically arrive within seconds.
- Familiar and easy to use for most Indian users.
- No need to visit a physical location.
Cons
- Frequent or large crypto-related transfers may attract scrutiny from your bank.
- Some banks flag accounts used for P2P crypto activity, which can lead to temporary holds or account reviews.
When to use UPI
UPI is a good choice for smaller amounts and users who are comfortable with the low but nonzero risk of bank scrutiny. It is the fastest option for completing a trade quickly.How CDM works
CDM (Cash Deposit Machine) allows you to deposit physical cash directly into the seller’s bank account using an ATM-style machine available at most bank branches. The deposit is credited to the account number you enter — no UPI app or internet banking required.How to pay
- The seller provides their bank account number and IFSC code on the trade page.
- Visit any CDM at a bank branch that supports cash deposits to that account.
- Insert cash and enter the seller’s account details. Keep your deposit receipt.
- Return to the platform and mark payment as sent once the deposit is complete.
Pros
- No digital trail linking your bank account to any crypto activity — the deposit appears as an ordinary cash transaction.
- Eliminates the risk of bank account freeze entirely.
- No UPI app, smartphone, or internet banking required at the point of payment.
- Preferred for larger amounts where bank scrutiny is a greater concern.
Cons
- Requires a physical visit to a CDM during banking hours.
- Bank processing time can add a short delay (typically under 30 minutes, but varies by bank).
- Less convenient for small or time-sensitive trades.
The no-freeze guarantee
Because the cash deposit carries no metadata connecting it to a cryptocurrency exchange, your bank has no automated way to associate the transaction with crypto activity. This makes CDM the safest payment method for users who want to protect their bank accounts from any crypto-related scrutiny.When to use CDM
Use CDM for larger transactions, for frequent trading, or any time you want to eliminate bank-freeze risk entirely.Method comparison
| Feature | UPI | CDM |
|---|
| Speed | Instant (seconds) | Slight delay (up to ~30 min) |
| Freeze risk | Low–moderate | None |
| Digital trail | Yes — bank transfer record | No — appears as cash deposit |
| Best for | Small amounts, fast trades | Large amounts, privacy-conscious users |
Use CDM for larger transactions or if you have any concern about bank account freezes. The extra step of visiting a CDM branch is a small trade-off for the complete removal of crypto-related transaction risk from your banking history.
