​
Understanding USDT Networks

USDT (Tether) is available on multiple blockchain networks. InventPay supports two:

​
USDT_ERC20 (Ethereum)

Advantages:
  • Most widely supported
  • High liquidity
  • Established network
Considerations:
  • Higher gas fees
  • Slower during network congestion
  • ~3 minutes for confirmations
Best for:
  • Large transactions where fees are negligible
  • Maximum compatibility
  • Users with Ethereum wallets

​
USDT_BEP20 (Binance Smart Chain)

Advantages:
  • Much lower fees
  • Faster confirmations (~45 seconds)
  • Growing ecosystem
Considerations:
  • Requires BSC-compatible wallet
  • Less universal than ERC-20
Best for:
  • Smaller transactions where fees matter
  • Frequent transactions
  • Users familiar with BSC
For most use cases, we recommend USDT_BEP20 due to lower fees and faster confirmations. However, always consider your customers’ wallet capabilities.

​
Network Selection Guide

Choosing the right network is crucial for your customers’ experience:
Recommended: USDT_BEP20 or create multi-currency invoices
  • Lower fees encourage completion
  • Fast confirmations improve UX
  • Stable value (pegged to USD)
Recommended: BTC or ETH - Network fees are negligible on large amounts
  • Most established and trusted - Better for accounting/auditing
Recommended: USDT_BEP20 - Low fees for recurring payments - Stable value simplifies pricing - Fast processing
Recommended: Multi-currency invoices
  • Let customers choose their preferred crypto
  • Maximize conversion rates
  • Accommodate different regions

​
Amount Currencies

When specifying amounts in API requests, you can denominate in different currencies:

​
Supported Amount Currencies

CurrencyCodeUse Case
US DollarUSDMost common, easy pricing
TetherUSDTCrypto-native pricing
BitcoinBTCBTC-denominated pricing
EthereumETHETH-denominated pricing
LitecoinLTCLTC-denominated pricing

​
Example: USD-based Pricing

{
  "amount": 29.99,
  "amountCurrency": "USD",
  "currency": "USDT_BEP20"
}
Result: Customer pays equivalent of $29.99 in USDT on BSC

​
Example: Crypto-based Pricing

{
  "amount": 0.001,
  "amountCurrency": "BTC",
  "currency": "BTC"
}
Result: Customer pays exactly 0.001 BTC (no conversion)
Using USD as amountCurrency is recommended for most businesses as it provides stable, predictable pricing regardless of crypto volatility.

​
Real-Time Exchange Rates

InventPay uses real-time exchange rates from multiple sources to ensure accurate conversions.

​
How Rates Work

  1. Rate Fetching: Aggregated from multiple exchanges
  2. Rate Locking: Locked when payment is created
  3. Rate Duration: Valid until payment expiration
  4. No Slippage: Customer pays exact amount shown

​
Rate Sources

  • Binance
  • Coinbase
  • Kraken
  • Additional aggregators
Exchange rates are locked at payment creation, protecting both you and your customers from volatility during the payment window.

​
Minimum Payment Amounts

Each cryptocurrency has minimum payment amounts to ensure economic viability:
CurrencyMinimum AmountReason
BTC0.001 BTC (~$40)Network fee considerations
ETH0.01 ETH (~$20)Gas fee considerations
LTC0.1 LTC (~$7)Network fee considerations
USDT_ERC2010 USDTGas fee considerations
USDT_BEP2010 USDTProcessing efficiency
Payments below minimum amounts will be rejected at creation. Always validate amounts before creating payment requests.

​
Network Fees

Understanding network fees helps you choose the right cryptocurrency:

​
Comparative Fee Structure

CurrencyTypical FeeFee Type
BTC$2-10Variable (network demand)
ETH$1-20Variable (gas price)
LTC$0.01-0.10Low and stable
USDT_ERC20$1-20Variable (gas price)
USDT_BEP20$0.10-0.50Low and stable
Customer pays network fees when sending payment. You pay network fees when withdrawing funds. Choose networks wisely to minimize costs.

​
Blockchain Confirmations

Each network requires different confirmation counts:

​
Confirmation Requirements

​
Why Different Confirmation Counts?

  • Security: More confirmations = more secure
  • Block Time: Faster blocks need more confirmations
  • Network Risk: Risk of chain reorganization
  • Industry Standards: Based on exchange best practices

​
Address Formats

Each cryptocurrency uses different address formats:

​
Format Examples

CRITICAL: USDT_ERC20 and USDT_BEP20 use similar address formats but are on different networks. Sending to the wrong network will result in loss of funds!

​
Best Practices

1

Always Specify Network

When accepting USDT, clearly communicate which network (ERC-20 or BEP-20)
2

Consider Your Audience

Choose currencies your customers are likely to have
3

Balance Fees and Speed

Higher fees often mean faster confirmations
4

Use Multi-Currency for Consumers

Let customers choose their preferred cryptocurrency
5

Test Both Networks

Test USDT on both ERC-20 and BEP-20 before going live
