Explore the platform
Use it the way you work.
Web, mobile, or straight through the API.
Web app. The full platform in your browser — policies, ledger, reporting and approvals, nothing to install.
Mobile app. Review and approve on the move. Signers see the amount, recipient and reason, and sign off from their phone.
API. Build it into your own systems. Every action available over a REST API, with the same rules enforced.
Built to be trusted.

Signing Uptime
Ledger. Every movement, accounted for.
Double-entry. Every movement recorded as at least two linked postings—every change has a matching side.
Reserved funds. Amounts are locked in Reserved before approval and external broadcast.
Historical balances. Reconstruct any position as of a chosen point in time.
Retry-safe. A repeated request returns the existing result—never a duplicate payment.
Every number explained. From an aggregated balance down to the account, posting and source operation.
See the ledger. From a single posting to the full position across your custody structure.
Integrate V3 Custody. One custody layer for every asset.
Programmable.
REST APIs and SDKs, live in days.
Multi-chain.
Dozens of networks, one integration.
Sovereign.
Self-hosted in your own environment.
Secure.
Threshold MPC on audited cryptography.
Reporting. Every number, explained.
Counterparty statements. All addresses of one counterparty in a single report—turnover, net flow, and activity.
Account statements. Opening balance, movements, adjustments, closing balance—reconciled against the ledger.
Assets and addresses. Separate reports per asset, address, or folder—identified by network and contract.
Approvals. Who initiated, which policy applied, who signed off, and how long it took.
Immutable snapshots. Fixed data cutoff and hash. The same report returns the same numbers, any time.
See reporting. From a single operation to a consolidated statement across the whole Vault.
Control before anything is signed.
Rules, limits, and approvals that decide who may move money.
Rules and limits. Set spend limits, allowlists and time locks — enforced at signing time, not after.
Multi-party approvals. Configurable m-of-n quorums. Value moves only when the right people sign off.
Per-user, per-scenario. Different rules for different users and flows — least-privilege by default
FAQ. Everything you need to know about self-hosted custody.
Multi-party computation splits a private key into shares held separately, so the full key is never assembled and there's no single point of failure. Unlike on-chain multisig, it's chain-agnostic and invisible to the blockchain; unlike cold storage, it stays fast and programmable.
Yes. Key generation, signing, the policy engine, and approvals all run in your own cloud, VPC, or data center. Your keys and data never leave your environment, and there's no external signer in the transaction path.
You define rules in the policy engine—spend limits, allowlists, time locks—and approval quorums (m-of-n). Every transaction is checked against your policies and must collect the required approvals before any key share signs. Every step is logged.
V3 Custody supports 20+ chains and thousands of tokens across major L1s, L2s, and EVM / non-EVM networks, with new networks added regularly. (replace with your actual coverage)
Institutions can deploy the full stack as a turnkey custody solution; teams can integrate the same infrastructure into their own product through APIs and SDKs. Same security model, two ways to adopt.
