+### SEP-0007 - URI Scheme to Facilitate Delegated Signing
+
+Defines the standard URI scheme that can be used to generate a URI that will serve as a request to sign a transaction. With this SEP’s guidance, non-wallet applications can have their their users sign a transaction without seeing the wallet user's secret key in any form since the URI (request) will typically be signed by the user’s trusted wallet where the secret keys are stored.
+
+This SEP defines a standard protocol enabling the following features within a wallet or other Stellar client:
+
+- Deeplinks payments (online)
+- QR code payments (online and offline)
+- Point of sale transactions (offline)
+- Peer to peer payments (online and offline)
+
+**Used by wallets and other applications.**

 ### SEP-0010 - Stellar Authentication
 
 Defines a standard way for clients (such as wallets or exchanges) to create authenticated web sessions for users holding a Stellar account. This SEP also supports authenticating users of shared or pooled Stellar accounts. Clients can use muxed accounts to distinguish users or sub-accounts of shared accounts.

+### SEP-0030 - Account Recovery: Multi-Party Recovery of Stellar Accounts
+
+Defines the standard API that enables an individual (e.g., a user or wallet) to regain access to a Stellar account that it owns after the individual has lost its private key without providing any third-party control of the account. Using this protocol, the user or wallet will preregister the account and a phone number, email, or other form of authentication with one or more servers implementing the protocol and add those servers as signers of the account. If two or more servers are used with appropriate signer configuration no individual server will have control of the account, but collectively, they may help the individual recover access to the account.
+
+The protocol also enables individuals to pass control of a Stellar account to another individual.
+
+This SEP enables the following use cases for a user:
+
+- Recover: Recover access to Stellar accounts for which they may have lost keys.
+- Share: Gain access to Stellar accounts that another user intends to share with them.
+
+**Used by wallets and other applications.**

 ### SEP-0031 - Cross-Border Payment API
 
 Defines the protocol for two financial accounts that exist outside the Stellar network (anchors) to interact with each other.
