SEP-52 Key Sharing

Allow people to split and share their secret keys in a safe and standard way.

SEP-52 is a standard for splitting secret keys with Shamir Secret Sharing. It is useful for backing up keys and for decentralized management of a key, similar to multisig schemes. Decaf uses this scheme in the background to back up keys, and Ledger and Trezor do too. Today the process is manual and needs a good knowledge of the protocol, so wallets and dApps should offer it directly.

• 01Wallets and dApps offer SEP-52 key splitting and recovery as a built-in option.
• 02A shared standard so splits made in one app can be recovered in another.
• 03SDK support so developers can adopt the scheme without reimplementing it.

Promotes the use of SEPs in general, and this mechanism for sharing and backing up keys in particular.
