ChangeNOW.io API already integrated for crypto swaps
Existing swap flow is functional

We need additional transaction-routing functionality added.

Project Requirements
Transaction Logic

Implement custom routing logic based on transaction amount:

If transaction amount is greater than $999
Route transaction to an internal wallet system
Select the next wallet using:
round-robin rotation or
randomized selection among active wallets
Wallets should be assigned per currency
If transaction amount is less than $999
Continue using existing ChangeNOW API flow

Admin Panel Features

Create an admin interface inside WordPress for managing wallets.

Required features:

Add/remove wallets for each cryptocurrency
Enable/disable wallets
Store wallet metadata/status
Wallet validation based on currency format
Example: BTC, ETH, LTC, etc. must validate correctly
Ability to view wallet usage history
Audit & Logging

System must log:

Which wallet was used
Transaction amount
Currency
Timestamp
Transaction/reference ID

Logs should be accessible for audit purposes.
