Transactions
Confirm transaction with password
Problem
The technical specifics of blockchain prevent the cancellation of transactions, which can be particulary painful for users in the event of errors in financial transactions.
Solution
Create artificial friction in user flow to prevent mistakes such as misclicks, approving transaction by accident, etc. Users must enter a short password (e.g. PIN) to explicitly confirm the transaction.
Connected patterns
Review transaction befre execution is a similar pattern. It also creates artificial friction in order to prevent accidents or faulty transactions.
