Self-Custody
for Business
M-of-N multisig vaults for your organization. Every signer uses two devices — browser extension and mobile app. No custodians. No MPC. No single point of failure.
The Problem
Businesses holding crypto today face impossible trade-offs
Custodial Solutions
Trust a third party with your keys
- Counterparty risk (FTX, Celsius)
- Account freezes without warning
- Vendor lock-in and high fees
MPC Providers
Key shards on vendor servers
- Vendor shuts down, you scramble
- Cannot verify their infrastructure
- Still a trust dependency
Single Hardware Wallet
One person, one device
- Key person risk
- No team governance
- Lost device = lost funds
How It Works
True self-custody at enterprise scale — no compromises
Create Your Organization
Set up your organization using your SSP Identity — a cryptographic proof derived from your devices, not just an email.
Invite Your Team
Add team members by their SSP Identity. Assign roles: Owner, Admin, Member, or Viewer. Every member needs SSP Wallet + SSP Key.
Create Multisig Vaults
Configure M-of-N vaults for different purposes — operations, treasury, payroll. Choose which signers are required.
Sign Together
Propose transactions through the web app. Each required signer approves with both their browser extension and mobile app. Broadcast when threshold is met.
Signing Architecture
Every signature requires two devices per signer
Enterprise Features
Everything your organization needs for secure crypto management
M-of-N Multisig Vaults
Configure any signing threshold for your team. 2-of-3, 3-of-5, or any combination that fits your governance model.
Role-Based Access
Owner, Admin, Member, and Viewer roles. Control who can propose, sign, or simply observe transactions.
Two-Device Signing
Every signer uses both a browser extension and a mobile app. Two keys per person, M-of-N across your team.
Multi-Chain Support
Bitcoin, Ethereum, Litecoin, Dogecoin, Flux, Polygon, BSC, Base, Avalanche, and more. One platform for all chains.
Transaction Proposals
Propose transactions with full details. Team members review, approve, or reject. Broadcast only when threshold is met.
Complete Audit Trail
Every action logged permanently. Member changes, vault operations, transaction approvals — full accountability.
Transaction Policy Engine
Granular controls that cascade from organization to vault to individual signer. Stricter policy always wins.
Default policies
Override & refine
Individual limits
Policies merge top-down — the stricter limit at any tier is enforced
Spending Limits
Per-transaction, daily, weekly, and monthly limits. Set in USD or native token. Aggregate and per-token controls.
Address Whitelist
Three modes: disabled, warn, or enforce. Label addresses, restrict by chain. Block unknown destinations entirely.
Time-Lock Delays
Configurable waiting period before broadcast. Trigger automatically above a USD threshold. Cancel before execution.
Admin Approval
Require admin sign-off on high-value transactions. Set a USD threshold — anything above it needs explicit approval.
Per-Signer Overrides
Set individual spending limits for each team member. Junior traders get tighter controls, senior execs get higher limits.
Velocity Tracking
Rolling 30-day spending windows per vault, per signer, and per token. Automatic enforcement with TTL-based cleanup.
Emergency Vault Freeze
Instantly freeze any vault with dual-device WK signing. Blocks all proposals until unfrozen. Incident response in seconds.
3-Tier Policy Hierarchy
Organization defaults cascade to vaults and signers. Vault-level overrides refine the rules. Stricter policy always wins.
3-tier policy hierarchy with 14+ configurable controls — included in every plan.
5-Layer Security
Defense in depth — every layer must be compromised for a breach
Layer 1: Device Security
OS-level security, biometric auth, secure enclaves on mobile
Layer 2: Dual-Device 2FA
Browser extension + mobile app required for every signature
Layer 3: On-Chain Multisig
Native Bitcoin multisig and EVM smart contract verification
Layer 4: Business Policies
Spending limits, address whitelists, time-locks, admin approvals, per-signer overrides, velocity tracking — 14+ configurable controls
Layer 5: Audit & Compliance
Immutable logs, login tracking, and compliance reporting
SSP Wallet is open source and audited by Halborn. Verify the code yourself.
