Welcome to the official IOTA Wallet Library Software documentation. You can use our documentation to help streamline integrating an IOTA Wallet into your applications. If you want to learn more about the IOTA client libraries, you can check out our blog post on how they work. is a general wallet library written in Rust. It is currently utilized by our wallet software, Firefly, and other software components across the IOTA ecosystem. contains all of the specs to safely build wallets or integrations that require value-based transfers, such as exchanges and pay-as-you-go systems. Additionally, amongst other features, includes account state management and backup, account creation, and transferring tokens. is also based on our official one-source-code-of-truth IOTA Rust library and can be integrated with the Stronghold enclave to achieve a maximum level of security.


You can use Stronghold to store account data of the It integrates the best security practices and is open-source.

With the library, developers no longer need to use a self-generated seed anymore. By default, the security of Stronghold creates and stores the encrypted seed, at rest. Additionally, it is not possible to extract the seed from Stronghold as a security measure.

Stronghold also uses encrypted snapshots that can easily be backed up and securely shared between devices. These snapshots are further secured with a password.
