What problem does it solve? AI agents often hallucinate Solana program addresses and use outdated SDK patterns, which can lead to lost funds when building multisig treasury, account abstraction, or stablecoin payment features. This Skill provides verified Squads Protocol program IDs, PDA derivations, and working SDK code for all three Squads products. ## Core Features & Use Cases - Squads V4 Multisig: Create multisigs with thresholds and permissions, manage vaults, proposals, voting, spending limits, batch transactions, and time locks via the @sqds/multisig SDK. - Smart Account Program: Build programmable wallets with session keys, passkeys, and policy-based execution through the Squads developer REST API. - Grid Payments: Integrate stablecoin rails, standing orders, virtual fiat accounts, KYC flows, spending limits, and webhooks using the Grid API. - Use Case: A team wants a 2-of-3 treasury multisig with a daily spending limit for operations. Use this Skill to derive the multisig and vault PDAs, create the multisig, configure the spending limit, and execute a vault transfer through the proposal flow. ## Quick Start Use the squads skill to create a 2-of-3 Squads V4 multisig on Solana devnet and show me how to propose and execute a vault transfer.
