Implementations

impl MultisigWallet

pub fn new(signers: Vec<String>, threshold: usize) -> Self

Creates a new MultisigWallet instance.

Arguments

• signers - A list of signer addresses.
• threshold - The minimum number of signatures required to approve a transaction.

Returns

• A new instance of MultisigWallet.

pub fn sign( &mut self, signer: &String, signature: &str, ) -> Result<(), &'static str>

Adds a signature to the wallet if the signer is valid and the signature is verified.

Arguments

• signer - The signer’s address.
• signature - The cryptographic signature of the signer.

Returns

• Ok(()) if the signature is successfully added.
• Err if the signature is invalid or the signer has already signed.

pub fn add_signer(&mut self, signer: String)

Adds a new signer to the wallet.

Arguments

• signer - The new signer’s address to be added.

pub fn remove_signer(&mut self, signer: &String)

Removes a signer from the wallet and updates the signature count if necessary.

Arguments

• signer - The signer’s address to be removed.

pub fn update_threshold( &mut self, new_threshold: usize, ) -> Result<(), &'static str>

Updates the signature threshold and checks if the current signature count is still valid.

Arguments

• new_threshold - The new signature threshold.

Returns

• Ok(()) if the threshold is successfully updated.
• Err if the threshold is invalid or if the current signatures do not meet the new threshold.

pub fn collect_signatures(&self) -> bool

Checks if the number of valid signatures meets or exceeds the threshold.

Returns

• true if the required number of signatures is met.
