Choose your integration
Choose Hosted, On my site, or Full Headless based on how much signer interaction and orchestration your product owns.
MultiSig Tools has one authorization core. Choose how much presentation and orchestration your product owns; Request, Intent, signer checks, effects checks, and execution policy remain authoritative in MultiSig Tools.
Hosted
Your service creates and tracks work. MultiSig Tools renders the signer review/signing surface through the returned review URL.
You own: business flow.
MultiSig Tools owns: signer UI.
On my site
Your product owns the signer UI and wallet UX. For Soroban Intents today, the owning Service can issue a short-lived signer/origin/current-plan browser capability and let the browser inspect and contribute AUTH directly.
Native Browser authorization is currently Intent/Soroban-scoped; Hosted remains the universal Human fallback.
Full Headless
Your UI, server, wallet adapters, Agents, webhook consumer, and executor orchestrate stable API operations directly. MultiSig Tools still verifies authority, plan identity, signatures, effects, expiry, and execution evidence.
You take over orchestration, not authority.
