Development of multi-currency light wallets, wallets for Dapps, as well as exchange services, market analytics tools. Web, desktop, mobile applications.
This project is a tool inside the Guarda Wallet cryptocurrency wallet allowing you to manage coins and Binance Chain tokens via a cold Ledger wallet.
The main task is to provide users with the capability to manage BNB cryptocurrency and bip-2 standard tokens from a cold Ledger wallet via the Web Guarda Wallet interface. Another related task is to solve the problem with a limited number of requests to the block explorer.
At the initial stage of the project, we had to deal with the features of the Binance Chain block explorer. With several simultaneous requests to the Binance Chain block explorer, temporary blocking problems may occur. This is the protection of the explorer to avoid DDoS attacks and reduce the load.
We improved the architecture of Guarda Wallet. This was made possible owing to the optimization of the query system - we increased the amount of information in a single query. Thus, it became possible to add tokens faster and improve the wallet’s speed as a whole.
In this fashion, Guarda and Ledger can now provide full support for the Binance Chain mainnet (including Binance Chain tokens), as well as benefit from the security and expanded functionality.
