Overview
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.
Support
Participants will get comprehensive support from Trezor, including technical guidance, development resources, and expert consultations. Our team helps every step of the way to ensure successful implementation. Afterward, selected applicants get a bounty ranging from $2,000 to $6,000, depending on integration complexity and depth of SLIP-39 implementation.
Application Process
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.
Frequently asked questions
Why did you switch from a standard backup to a new format?
We believe this improved 20-word standard builds on our previous one with many important improvements for wallet backup and recovery. It provides more ways to make backups, guaranteeing safer and more reliable self-custody for everyone.
You can seamlessly move from a standard Single-share Backup to an advanced Multi-share Backup for distributed security without a single point of failure.
It also includes a new wordlist, with specially chosen words that are easier to tell apart than before. If you make one mistake in your backup, you’ll know which word is wrong. If you make two or three mistakes, you’ll know how many words are incorrect.

Which wallets support this backup standard?
At present, third-party wallets like Rabby, Electrum, Sparrow, and BlueWallet support the SLIP39 standard. We're working with more wallets to expand compatibility and will share updates as new integrations are completed.
We're also encouraging better backup support in software wallets through a bounty program. This program provides both financial and technical support to wallet providers looking to implement SLIP39.
Back in 2013, we were in the same situation with our legacy backup standard—we invented it first, and then the industry followed.

How can I recover my funds with SLIP39?
Right now, your best option is to buy a new Trezor hardware wallet and recover on it. You can also recover with another hardware wallet or with compatible software wallets like Rabby, Electrum, and BlueWallet for Bitcoin, but remember: software wallets have all the risks of any hot wallet. More options are sure to arrive in the future.
