Extended Requirements

If your provider fulfills the extended requirements below, it may be eligible to receive the listed property. We regularly screen signal providers in bifrost-wallet.providerlist.json for eligibility. If your provider has been eligible for more than 30 days without receiving the listed property or you think a mistake has been made, you may open an issue and provide data supporting your claim.

Trustworthy

• The team developing and running the signal provider is known to other signal providers
• The on-chain address is referenced on the signal provider's website (enforced 2023-03-31)

Resilient

• The team is only running one signal provider attracting vote power per network
• The provider uses a private node to submit prices

Independent

• The team has no legal, development or operational ties to other signal providers
• The provider uses an algorithm developed in-house or an open-source alternative

Available

• The provider has enough voting power to participate in the FTSO system
• The provider has at least 95% uptime, measured over the last 30 days

Recommendations for Developers

If you're a wallet or dapp developer using bifrost-wallet.providerlist.json in your software, we recommend that you:

1. Hide all providers missing the listed property from contexts where users choose between different providers, such as in searchable signal provider lists.
2. Show all providers in contexts where a choice has already been made, such as in confirmation views and transaction details.
