Processing mode
Each wallet's settings include a Processing mode: Fast or Secure. This parameter defines the filtering criteria for incoming on-chain transactions. The selected mode determines how quickly the service processes your transaction, imports it, and matches it to an invoice.
Keep in mind: once a transaction passes the selected mode's filter and enters the database, it is instantly matched to the corresponding invoice (if one is found) and moves it to Paid.
Fast mode
How it works: the system counts a transaction as soon as it appears on the network with the minimum number of confirmations (usually 1 block or the Confirmed status).
When to use:
- For selling low-cost goods and services (digital content, subscriptions)
- For micropayments
- When instant product delivery is critical for your business
Specifics: there is a very small risk of a blockchain reorg, where a transaction included in the first block is reversed by the network a few seconds later. In Fast mode, the system may confirm such a payment before the network rejects it.
Secure mode
How it works: the system deliberately ignores an on-chain transaction until it reaches the community-recommended number of confirmations (finality). For Bitcoin, for example, this may be 3 blocks.
When to use:
- For selling expensive goods and services
- For topping up large user balances
- For physical goods whose delivery costs money and cannot be recalled
- For any operation where the financial risk of a reversed payment outweighs the inconvenience of waiting
Specifics: the customer does not see the payment confirmed on your site right away—it appears a few minutes later (depending on the network), once the transaction is considered safe from the blockchain's perspective.
