When a client sends funds to the invoice address, our system detects the transaction once it reaches the mempool.
At that point:
The client has 15 minutes to initiate payment
Once detected, the timer extends to 24 hours for confirmation
⚠️ Important Exception (ETH & ERC20):
For Ethereum and ERC20 tokens, we can’t detect mempool entries. This means the 15-minute timer is final. If the transaction isn't confirmed after that, it may be rejected.
