Summary

Trinity Wallet was the official desktop and mobile software wallet for the IOTA cryptocurrency, developed and maintained by the IOTA Foundation. In February 2020, a supply chain attack exploiting a compromised MoonPay SDK delivered via CDN resulted in the theft of approximately 8.55 Ti (teraIOTA) worth roughly $2 million from 50 user seeds, forcing the IOTA Foundation to shut down the entire IOTA network for 27 days. Trinity was subsequently deprecated in April 2021 following the Chrysalis protocol upgrade, with the Firefly wallet introduced as its replacement.
