Mainnet is not open yet. SigVault is young software that will handle real money. We publish our threat model, our trust boundaries, and our limitations — read them before you deposit.
Signers can be anywhere.
A hardware wallet on someone's desk, a service signing through the SDK — one session collects from all of them. Partial signatures relay through the coordinator, which can do nothing with them until the threshold is met.

The seller refused. Two of three is still a quorum, so the escrow settles without them — and would not have settled with the arbiter alone.

The private key never leaves the device. SigVault sees the signature, never the key that made it.
Write the rule.
Not the workaround.
A quorum, a recovery path, and a timelock — composed in the builder and compiled straight to a descriptor. Pick a scenario to see the shape it produces.
Any two of the three entities can spend. The CFO and the controller sit in different legal entities, so a single compromised office is never a quorum.
If the operating quorum is lost, four named board members can recover — but only after the timelock, and only three of them together.
tr(unspendable,{multi_a(2,K_cfo,K_controller,K_auditor),and_v(v:older(26280),multi_a(3,K_b1,K_b2,K_b3,K_b4))})
Every path on the left compiles into this one expression. It is what the network checks at spend time — nothing outside it can move the funds, including us.
