Implementations

impl WinterWallet

pub fn new( id: [u8; 32], current_root: [u8; 32], position: SigningPosition, ) -> Self

Build a wallet facade from explicit account state and local position.

pub fn from_account( account: &WinterWalletAccount, position: SigningPosition, ) -> Self

Build a wallet facade from a deserialized on-chain account.

pub fn id(&self) -> &[u8; 32]

Wallet ID committed by the account.

pub fn pda(&self) -> &Address

Wallet PDA.

pub fn current_root(&self) -> &[u8; 32]

Current root loaded from chain.

pub fn position(&self) -> SigningPosition

Local signer position expected for the next signature.

pub fn advance_plan( &self, new_root: &[u8; 32], inner_instructions: &[Instruction], ) -> Result<UnsignedAdvance, Error>

Build an unsigned Advance from arbitrary inner CPI instructions.

pub fn withdraw_plan( &self, receiver: &Address, lamports: u64, new_root: &[u8; 32], ) -> Result<UnsignedAdvance, Error>

Build an unsigned Advance wrapping the built-in lamport withdraw CPI.

pub fn close_plan( &self, receiver: &Address, new_root: &[u8; 32], ) -> Result<UnsignedAdvance, Error>

Build an unsigned Advance wrapping the built-in close CPI: sweeps all lamports to receiver and tears the wallet PDA down.

pub fn transfer_plan( &self, source_token_account: &Address, destination_token_account: &Address, token_program: &Address, amount: u64, new_root: &[u8; 32], ) -> Result<UnsignedAdvance, Error>
