Why Solana Multisig Addresses Are Hard
Solana accounts must be created before they exist. See why that makes a multisig wallet address hard, and how Bitcoin and Ethereum sidestep it.
This series unpacks the multisig program the SSP team designed and built for Solana support: why a wallet address on Solana is harder than it looks, and how SSP makes the address the member set itself. It compares the design to Squads V4 and shows how durable nonces let two devices co-sign minutes apart.

Solana accounts must be created before they exist. See why that makes a multisig wallet address hard, and how Bitcoin and Ethereum sidestep it.

How SSP built a self-initiating Solana multisig wallet where the address itself is the member set, pre-fundable and permissionless to register.

An honest comparison of two Solana multisig designs — SSP's deterministic primitive and Squads V4's audited governance platform.

Why a Solana blockhash expires before your phone can approve, how durable nonces fix it, and how SSP derives the nonce account so you never store it.
