When startups begin developing a crypto wallet, setting the right foundation from the start is critical. Early decisions play a major role in how safe and adaptable the wallet will be in the long run.

Key areas startups should focus on first:

• Build a strong system design that allows future features to be added easily

• Plan clear user access control and private key handling from the beginning

• Start by supporting basic assets and transactions before moving to advanced options

• Test the wallet under real usage conditions to avoid issues after launch

By taking a step-by-step approach, the wallet stays stable and reliable. This builds user confidence over time and allows the wallet to grow naturally alongside the exchange business.
