Avoid wallet address errors - no more copying long strings of characters or risking sending funds to the wrong address. Use human-readable usernames like @jaycode or @john instead of crypto addresses. Link multiple wallets to one username, for flexibility and easy management. Streamline payroll setup - when scheduling or streaming payments, employers can simply type a username, and Paynest automatically routes funds to the correct wallet. Maintain privacy and consistency - even if an employee changes their wallet, their username remains the same, keeping payroll records intact.
