In the previous update, we highlighted some of the ongoing developments for the security audit of the Trinity wallet. This post will mainly outline our progress and results.

If you have any questions about ongoing development of the Trinity wallet, please join the #trinity-discussion Discord channel.

As announced in our last update, the Trinity mobile and desktop applications are undergoing a security audit by a leading security firm. The audit will assess authentication, storage areas, configuration and validation in the applications, and will ensure that a high level of security is in place. Since submission for security audit, we have tackled the outstanding bug list for mobile reported by our beta testers.

Here is a summary of some of the recent completed and in-progress works.

After bug fixing, our focus has shifted towards completing the outstanding issues and features required for full release.

Taking into consideration advice from the security audit team, we aim to introduce deep linking into the final release. This will allow users to automatically open Trinity by clicking on a link on a vendor’s site, ready to pay the correct amount to the correct address.

We also hope to have manual sweeps ready before (or soon after) full release. Trinity does not traditionally allow spending from “previously spent addresses” for safety reasons. This new Manual Sweep feature will unblock these funds by securely transferring them to an unused address, whilst minimising the chance of attack.

Another area that we are focusing on before full release is test coverage. While Trinity already has good overall test coverage, it still misses some tests for critical areas such as the keychain and the Realm database. We also plan to add end-to-end tests, which will allow us to test changes in an environment that simulates user behavior.

To this end we actively encourage community pull requests, and our team is always ready to help you get up to speed on our Discord channels. Please do join the IOTA Discord server. We would love to see you there.
