SSP Enterprise Overview

SSP Enterprise is multi-party crypto custody for teams. Your organization holds the keys, your team co-signs transactions, and the platform handles the coordination — proposals, approvals, audit trail, and policy enforcement.

It runs on the same two-device security model as SSP Wallet (browser extension + mobile app), but instead of one person controlling one wallet, your team collectively controls organizational vaults.

What you actually get

  • Vaults that are real on-chain multisigs. Not a custodian. Not MPC with a vendor share. Native Bitcoin multisig and EVM smart contract multisig, derived from your signers' xpubs.

  • Pick your threshold. 2-of-3 for a small team. 3-of-5 for a treasury council. 5-of-9 for a board. Whatever matches how your team actually makes decisions.

  • Two devices per signer (default). In the default Dual Signing mode, a compromised laptop alone can't sign and a compromised phone alone can't sign — both are required on every signature, for every signer. Optional Key Only / Wallet Only signing modes trade this two-device protection for more signers per vault (each signer signs with a single device) — see Creating Multisig Vaults.

  • One platform, twelve chains. BTC, ETH, LTC, DOGE, BCH, ZEC, RVN, FLUX, MATIC, BNB, AVAX, BASE — without juggling tools.

  • A policy engine that's actually configurable from the UI. Spending limits, address whitelists, time-locks, admin approvals, per-signer overrides. No Solidity. No modules to deploy.

  • An audit log you can hand to an auditor. Every member change, vault op, proposal, and signature, attributed and timestamped.

  • Open source. SSP Wallet and SSP Key are public. The cryptography is verifiable.

How the pieces fit

  • WK Identity is your unique cryptographic identity, derived from a 2-of-2 multisig of your SSP Wallet + SSP Key public keys. No password. No email required for first login. You sign in by signing a challenge with both devices.

  • Organizations group your team. One owner, several admins, members, viewers.

  • Vaults are the M-of-N multisig wallets where funds live. One organization can have many vaults across different chains.

  • Proposals are transactions waiting on signers. Each designated signer approves with their wallet + key. Threshold met → broadcast.

What you need before signing in

Every team member who'll be on a vault needs to be set up as an SSP Wallet user first:

  1. SSP Wallet browser extension — Chrome or Firefox

  2. SSP Key mobile app — iOS or Android

  3. Wallet + Key paired and synced — see the SSP Wallet first-time setup

Once that works as a normal personal wallet, you can sign in to SSP Enterprise.
