4. Fundamentals of a Wallet
6. What is a Crypto Wallet A cryptocurrency wallet is a software program that holds your public and private keys and interacts with various blockchains enabling you to send and receive digital assets, including cryptocurrencies, stablecoins and NFTs (non-fungible tokens).

13. Hot Wallets • Connected to the internet • Web-based, desktop & mobile wallets • Free Cold Wallets • Offline • Hardware wallets • Expensive Types of Wallets
14. Non-Custodial Wallets • You have complete control of your private keys • Lose your private key/seed phrase, and you lose access to your assets • No KYC or AML processes or procedures Types of Wallets Custodial Wallets • Third-party has control of private keys • Recovery mechanisms in place so you can regain access to your wallet • KYC and AML processes and procedures
15. Understanding the Complexities
17. Browser Compatibility
18. Browser Compatibility
19. Chrome Extension Manifest V3
20. Blockchain Tooling The maturity of blockchain developer tools is still in its early stages as developers explore and experiment with different ways to build decentralised applications (dApps) on blockchain networks.
21. Blockchain Environment Cost • Pay gas fees to cover the computational effort required to execute the specific operation on the network Speed • Blocks are committed once every twelve seconds Control • No entity has control over the network
22. Browser Automation Framework
23. Release Process for Browser Extensions Review times “If your extension is pending review for more than three weeks, please contact developer support to request assistance.” Store violations Rejections and warnings.
24. Tools and Techniques
25. Communication
26. DevTools
27. Feature Flags Use feature flags as part of your build or feature release process. Feature flags help reduce risk, allowing you to do controlled testing. Build and deploy new features as part of the regular release process without having those features generally available. The development of the feature is conveniently decoupled from their exposure.
28. Controlling the Blockchain Local Blockchain • Personal Ethereum Blockchain e.g. Truffle Suite Ganache DevNets • Private environment against Mainnet data e.g. Tenderly DevNets Public Testnet • Public testnet that developers can use e.g. Sepolia
29. Keep Tools Up to Date
30. Errors: • Stack trace • Breadcrumbs • Custom context • Tracking releases • Session replay Application Performance Monitoring
