⚠️ Most important: pick the right network
Supported networks
TRC20 (TRON)
Most popular USDT network. Low fees (~$1), fast (1-3 min).
BEP20 (BSC)
Binance Smart Chain. Low fees, supported by all major wallets.
Polygon
Polygon (MATIC) network. Low fees, great for DeFi-native users.
ERC20 (Ethereum) is not supported — gas is too expensive for small top-ups. Solana and others are on the roadmap.
How to top up
Confirm the amount
The payment page shows the final amount to send. If volume discounts apply they’re already factored in.
Send USDT
A QR code and wallet address appear. Send USDT from your wallet / exchange strictly through the selected network.
If your top-up is delayed
Confirmation time depends on the network:| Network | Typical time |
|---|---|
| TRC20 | 1-3 min |
| BEP20 | 1-5 min |
| Polygon | 2-10 min |
- Check the transaction in a blockchain explorer (TronScan / BscScan / PolygonScan) — it should be confirmed (status: success).
- Confirm the network matches the one you selected on RuAPI.
- Email support@ruapi.ai with the transaction TXID.
In 99% of cases, delays are because the wallet’s network didn’t match the one selected on RuAPI. Unfortunately, USDT sent through the wrong network technically cannot be recovered — it doesn’t exist on the network we expect deposits on.
Minimum amount and discounts
- Minimum: 1 USDT per top-up.
- Maximum: no hard limit (one transaction up to ~1000 USDT is comfortable).
- Volume discounts: bigger top-up = bigger discount. Exact tiers on the top-up page.
Security
- The wallet address shown on the payment page is generated for your order — it’s tied to your user. Don’t reuse old addresses from previous payments.
- For phishing protection, always reach www.ruapi.ai via your bookmark (not from email links) and compare the wallet address against what our site displays.
