Critical Implementation Questions

1. Deposit Address Generation

Solution: Exchanges can use a single XRP address with destination tags for user identification.

Important Consideration: Enable RequireDestinationTag setting to mandate tag inclusion for all incoming transactions (XRPL Documentation).

2. Node Infrastructure Options

Self-hosted node: For transaction broadcasting and ledger operations
Public API: Alternative for querying transactions and broadcasting

3. Deposit Monitoring System

Key implementation steps:

Configure address monitoring
Implement transaction scanning
Set up tag-based user identification

Technical Implementation Details

Transaction Processing Workflow

Balance Check: GET /v2/accounts/{address}/balances
Fee Calculation: /v2/network/fees?interval=day&limit=3&descending=true
Account Info Retrieval: Query account_info for sequence numbers

XRP Sequence Mechanism

Unlike Ethereum, XRP transactions must use the exact next sequence number. Transactions with incorrect sequence values will fail with terPRE_SEQ error.

Offline Signing Solutions

Recommended Implementation Approaches

Python Service Integration (Preferred)
- Handle transaction serialization server-side
- Client only performs signing operations
Custom Serialization Library
- Implement Payment-type specific serialization
- Reference existing implementations in ripple-lib
Rippled Signing API
- Enable signing_support in config
- Requires compiled rippled executable

Example Signing Request

{
  "method": "sign",
  "params": [{
    "secret": "your_secret_key",
    "offline": true,
    "tx_json": {
      "TransactionType": "Payment",
      "Account": "your_address",
      "Destination": "recipient",
      "Amount": "1000000",
      "Sequence": 123,
      "Fee": "12"
    }
  }]
}

Frequently Asked Questions

Q: How do I handle untagged deposits?

A: Implement RequireDestinationTag account setting to reject untagged transactions automatically.

Q: What's the minimum XRP balance requirement?

A: Accounts must maintain a 20 XRP reserve (10 XRP for testnet).

Q: How often should I query for new deposits?

A: Poll every 3-5 seconds for high-volume exchanges, or use webhooks if available.

Q: Can I reuse destination tags?

A: Yes, but implement a system to track active/expired tags for security.

Q: What transaction fee should I use?

A: Current network median fee plus 20% buffer for priority (typically 10-15 drops).

Q: How do I test my integration?

A: Use the XRP Testnet and testnet faucets for free XRP to validate your implementation.
