Our enhanced 20-word backup standard ensures a more robust process for backing up and recovering your wallet compared to the legacy standard. With an upgraded, user-friendly wordlist and seamless transition to Multi-share Backup, SLIP39 offers superior security with no single point of failure.
In 2013, SatoshiLabs created the BIP-39 standard, widely adopted by wallets today. As the next iteration in self-custody security, we are moving towards SLIP-39 as the default wallet backup standard in Trezor. We are offering a Bounty Program to onboard early adopters of SLIP-39 and the multi-share backup feature.
Participants will receive comprehensive support from Trezor, including access to technical guidance, development resources, and consultations with our experts. Our team is committed to assisting you at every step to ensure successful implementation. Upon completion, chosen applicants will receive a bounty ranging from $2,000 to $6,000, depending on the complexity and depth of SLIP-39 integration achieved.
We are currently accepting applications on an ongoing basis. The review process will assess each proposal’s alignment with SLIP-39 standards, implementation timeline, and education plan for users. Submissions are evaluated as they come in, and selected projects will receive the necessary development resources and support to complete the integration.
We strongly believe this enhanced 20 word standard is an evolution of the previous standard with many significant improvements to wallet backup and recovery. It offers more variability in creating backups, ensuring safer and more reliable self-custody for everyone.
Users can seamlessly upgrade from a standard Single-share Backup to an advanced Multi-share Backup, obtaining distributed security with no single point of failure for backup.
Additionally, it comes with an upgraded wordlist, with carefully selected words that are easily distinguishable from each other compared to the old standard. In case of one mistake in the backup, users can identify which word is incorrect. In the case of 2 or 3 mistakes, they can identify how many words are incorrect.
At the moment this enhanced backup is supported by Trezor and three software wallets - Rabby, Electrum and BlueWallet. Other market players such as Wasabi, Sparrow, MEW/Enkrypt, Ambire and NuFi intend to integrate their support by the end of this year (2024).
Furthermore we actively encourage enhanced backup support integration into software wallets through a bounty program. This initiative extends financial and expertise support to software wallet providers seeking to implement SLIP39.
We were in the same situation back in 2013 with our legacy backup standard, where we were the first who invented it and the rest of the market followed us.

Right now, you should ideally buy a new Trezor hardware wallet and recover it there. Alternatively you can recover access in another hardware wallet, or use available software wallets Rabby, Electrum and BlueWallet for bitcoin, but they possess the risks of every hot wallet. Later on, we are sure more alternatives will emerge in the market.
