What is multisig, and why it matters
Plain-English intro to multi-signature wallets — what m-of-n really means, how it differs from a single-key seed backup, and when it's worth the friction.

Multisig Deep Dive
A seven-part series turning the existing 2-of-2 explainer into a full multisig cluster: what multisig is and why it matters, when m-of-n configurations beat the alternative, the BIP48 derivation path that lives under SSP, what Schnorr aggregation changes, social recovery vs. multisig, the single-signer UX, and the failure modes a serious multisig wallet has to handle.

2-of-2 vs 2-of-3 vs m-of-n multisig: picking the right threshold
Multisig threshold guide for solo, joint and team setups: when 2-of-2 suffices, when 2-of-3 starts to pay for itself, when teams need 3-of-5.

BIP48 explained: the derivation path behind SSP
How BIP48 standardises multisig wallet construction, why SSP follows it, and what that means for recoverability outside SSP.

Schnorr signatures and multisig aggregation
How Schnorr's linearity lets multisig become a single on-chain signature, what MuSig2 does, and what aggregation changes for SSP fees and privacy.

Social recovery vs multisig: two answers to losing a key
Multisig protects against theft; social recovery protects against loss. Side-by-side comparison of when each wins for solo, joint and team setups.

Single-signer multisig: how SSP makes two devices feel like one wallet
How SSP collapses 2-of-2 multisig into single-signer UX, what is hidden, where it breaks, and why the friction you see is the security.

Multisig failure modes and how SSP mitigates them
Five multisig failure modes: lost device, lost seed, key compromise, server outage, total destruction — and the recovery path for each in SSP.
