This is a critical question  and something many developers face when building custodial wallets. Several key mistakes can cause projects to fail 


1.Poor private key management   Many developers mishandle private keys, putting user funds at serious risk.   Storing keys insecurely or without encryption makes wallets vulnerable to hacks.   Proper key storage and strong encryption are essential for user trust.


2.Ignoring compliance   Skipping KYC/AML and local regulations can lead to legal troubles.   Non-compliance can result in fines, restrictions, or project shutdown.   Integrating automated compliance processes helps keep the wallet fully legal and           trustworthy.


3.Neglecting user experience   A confusing or complicated wallet interface drives users away.   Poor UI/UX can result in transaction errors or reduced adoption.   Simple, intuitive designs improve usability and build long-term trust.


4.Skipping security audits   Unverified smart contracts and backend systems can be exploited.   Even minor vulnerabilities can lead to financial losses or reputational damage.   Regular audits and penetration testing ensure the wallet is safe for users.


5.No scalability planning  Wallets may work with small user bases but fail under heavy traffic.  Crashes or slow transactions frustrate users and harm credibility.   Planning for scalability ensures smooth performance as the platform grows.


6.Lack of post-launch support  Without updates, maintenance, or customer support, user trust declines quickly.  Technical issues or failed transactions can generate negative feedback.  Ongoing support helps maintain reliability and positive user experience.
