The program for all derivations is the Squads V4 program ID: ``` SQDS4ep65T869zMMBKyuUq6aD6EgTu8psMjkvj52pCf ``` PDA Account Structure *** ## Multisig The multisig account is the main config for your Squad. Contains threshold, members, config authority, and time-lock settings. ### PDA Derivation ``` ["multisig", "multisig", createKey] ``` The `createKey` is a unique Public Key made specifically to derive the Multisig PDA. ### Account Structure ```rust theme={null} #[account] pub struct Multisig { /// Key that is used to seed the multisig PDA. pub create_key: Pubkey, /// The authority that can change the multisig config. /// This is a very important parameter as this authority can change the members and threshold. /// /// The convention is to set this to `Pubkey::default()`. /// In this case, the multisig becomes autonomous, so every config change goes through /// the normal process of voting by the members. /// /// However, if this parameter is set to any other key, all the config changes for this multisig /// will need to be signed by the `config_authority`. We call such a multisig a "controlled multisig". pub config_authority: Pubkey, /// Threshold for signatures. pub threshold: u16, /// How many seconds must pass between transaction voting settlement and execution. pub time_lock: u32, /// Last transaction index. 0 means no transactions have been created. pub transaction_index: u64, /// Last stale transaction index. All transactions up until this index are stale. /// This index is updated when multisig config (members/threshold/time_lock) changes. pub stale_transaction_index: u64, /// The address where the rent for the accounts related to executed, rejected, or cancelled /// transactions can be reclaimed. If set to `None`, the rent reclamation feature is turned off. pub rent_collector: Option, /// Bump for the multisig PDA seed. pub bump: u8, /// Members of the multisig. pub members: Vec, } ``` *** ## Proposal Tracks votes cast by members for a given transaction. Stores the status and enables execution once threshold is met. ### PDA Derivation ``` ["multisig", multisig_key (as buffer), "transaction", transaction_index, "proposal"] ``` The `transaction_index` is auto-incrementing based on your Multisig's total transactions. ### Account Structure ```rust theme={null} #[account] pub struct Proposal { /// The multisig this belongs to. pub multisig: Pubkey, /// Index of the multisig transaction this proposal is associated with. pub transaction_index: u64, /// The status of the transaction. pub status: ProposalStatus, /// PDA bump. pub bump: u8, /// Keys that have approved/signed. pub approved: Vec, /// Keys that have rejected. pub rejected: Vec, /// Keys that have cancelled (Approved only). pub cancelled: Vec, } ``` *** ## Vault Transaction Stores a transaction message that is voted on via a proposal. ### PDA Derivation ``` ["multisig", multisig_key (as buffer), "transaction", transaction_index] ``` ### Account Structure ```rust theme={null} #[account] pub struct VaultTransaction { /// The multisig this belongs to. pub multisig: Pubkey, /// Member of the Multisig who submitted the transaction. pub creator: Pubkey, /// Index of this transaction within the multisig. pub index: u64, /// bump for the transaction seeds. pub bump: u8, /// Index of the vault this transaction belongs to. pub vault_index: u8, /// Derivation bump of the vault PDA this transaction belongs to. pub vault_bump: u8, /// Derivation bumps for additional signers. /// Some transactions require multiple signers. Often these additional signers are "ephemeral" keypairs /// that are generated on the client with a sole purpose of signing the transaction and be discarded immediately after. /// When wrapping such transactions into multisig ones, we replace these "ephemeral" signing keypairs /// with PDAs derived from the MultisigTransaction's `transaction_index` and controlled by the Multisig Program; /// during execution the program includes the seeds of these PDAs into the `invoke_signed` calls, /// thus "signing" on behalf of these PDAs. pub ephemeral_signer_bumps: Vec, /// data required for executing the transaction. pub message: VaultTransactionMessage, } ``` *** ## Batch Stores a collection of vault transactions for grouped voting and execution. ### PDA Derivation ``` ["multisig", multisig_key (as buffer), "transaction", transaction_index] ``` ### Account Structure ```rust theme={null} #[account] #[derive(InitSpace)] pub struct Batch { /// The multisig this belongs to. pub multisig: Pubkey, /// Member of the Multisig who submitted the batch. pub creator: Pubkey, /// Index of this batch within the multisig transactions. pub index: u64, /// PDA bump. pub bump: u8, /// Index of the vault this batch belongs to. pub vault_index: u8, /// Derivation bump of the vault PDA this batch belongs to. pub vault_bump: u8, /// Number of transactions in the batch. pub size: u32, /// Index of the last executed transaction within the batch. /// 0 means that no transactions have been executed yet. pub executed_transaction_index: u32, } ``` *** ## Config Transaction Similar to vault transaction but deals directly with configuration parameters. Used when there is no set config authority. ### PDA Derivation ``` ["multisig", multisig_key (as buffer), "transaction", transaction_index] ``` ### Account Structure ```rust theme={null} #[account] pub struct ConfigTransaction { /// The multisig this belongs to. pub multisig: Pubkey, /// Member of the Multisig who submitted the transaction. pub creator: Pubkey, /// Index of this transaction within the multisig. pub index: u64, /// bump for the transaction seeds. pub bump: u8, /// Action to be performed on the multisig. pub actions: Vec, } ``` ## See Also * [Multisig Account (SDK)](/developers/typescript-sdk/accounts/multisig) * [Transaction Accounts (SDK)](/developers/typescript-sdk/accounts/transactions) * [Proposal Account (SDK)](/developers/typescript-sdk/accounts/proposal) This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
