What problem does it solve? Building treasury management, account abstraction, or stablecoin payment features on Solana requires deep knowledge of Squads Protocol's three products, their program IDs, PDA derivations, and REST APIs, which are scattered across multiple documentation sources. ## Core Features & Use Cases - Squads V4 Multisig: Create multisigs with member permissions, manage proposals and voting, execute vault transactions, and configure spending limits using the @sqds/multisig SDK. - Smart Account Program: Implement account abstraction with session keys, passkey authentication, spending policies, and direct debits via the REST API. - Grid Payments: Build stablecoin payment flows with standing orders, virtual accounts for fiat rails, KYC tiers, and HMAC-signed webhooks. - Use Case: A team wants to replace a single-owner treasury wallet with 2-of-3 governance. Use this Skill to derive the multisig and vault PDAs, create the multisig with proper permissions, and wire up spending limits for emergency operations. ## Quick Start Ask the assistant to create a Squads V4 multisig with two members and a threshold of two using the @sqds/multisig SDK.
