Processing & Retries

When a payin comes due, Loop checks the wallet’s balance and authorization every 10 minutes until the auto-cancellation window is hit (typically set at 7 days). Companies can change the auto-cancellation window to any number of days. Once sufficient funds and approval are confirmed, the transaction is sent on-chain. This process virtually eliminates transaction failures.

​
Potential Failures

Transactions can only fail if someone maliciously moves funds or changes approvals between our balance check and transaction submission. This requires:
  • Developer-level blockchain knowledge
  • Active monitoring of our pending transactions
  • Submitting competing transactions with higher fees
On fast blockchains like Solana (millisecond confirmation times), this window is extremely narrow. If someone acts maliciously in this way, you’ll notice the failure immediately and may want to reconsider them as a customer.
