Seismic
Seismic is an L1 blockchain capable of encrypting arbitrary smart contracts. Deploying a single Solidity contract is sufficient to launch an encrypted DeFi protocol, no custom infrastructure required.

SP
Self Protocol
Self is an identity wallet that lets users generate privacy-preserving proofs from government-issued IDs such as passports. By scanning the NFC chip in their ID document, users can prove their validity while only revealing specific attributes such as age, nationality or simply humanity. Under the hood, Self uses zk-SNARKs to make sure personal data is redacted, but the document is verified. Use cases unlocked include: - Airdrop protection: Protect a token distribution from bots - Social media: Add humanity checks to user's profiles - Quadratic funding: Prevent farmers from skewing rewards - Wallet recovery: Safeguard assets using IDs as recovery sources - Compliance: Check a user is not part of a sanctioned entity list

Sentinel
Sentinel is a mobile ‘watch only’ wallet that allows you to track the balances and transactions of your offline, cold storage or just about any of your bitcoin wallets. Sentinel tracks all types of addresses or extended public keys and can also generate new addresses to enable you to receive bitcoin into your offline wallets on the move. Sentinel never has access to your private keys, so never has the power to spend your funds. You can however pass Sentinel a pre-signed hex formatted transaction from a device that holds your private keys and then use Sentinel to broadcast to the Bitcoin network.
