Icon LinkWallets

Wallets serve as a centralized interface for all account-related behaviors. They allow you to:

• Inspect UTXOs: Check available coins for spending.
• Prepare and send transactions: Build, sign, and submit transfers.
• Manage network fees: Pay for transaction execution and contract deployment.

Every wallet requires a provider to communicate with the network.

Icon LinkTypes of Wallets

There are two primary types of wallets available in the SDK:

Icon LinkLocked Wallets

• Purpose: Used for read-only operations.
• Interface: Implements the ViewOnlyAccount trait.
• Use Cases: Checking balances, viewing UTXOs, and monitoring transactions without the ability to sign or submit transactions.

Icon LinkUnlocked Wallets

• Purpose: Supports full account functionality.
• Interface: Implements the ViewOnlyAccount and Account traits.
• Additional Requirement: In addition to a provider, an unlocked wallet must include a signer.
• Use Cases: Transferring funds, signing messages, submitting transactions, and performing state-changing operations.

Icon LinkSigner Options

The SDK offers multiple signing methods to suit different scenarios:

• Private Key Signer:
  Use when you have direct access to your account’s private key.

• AWS KMS Signer: Delegate signing operations to AWS Key Management Service, enhancing key security by offloading cryptographic operations.

• Google KMS Signer:
  Similar to AWS KMS, this option delegates signing to Google’s Key Management Service.

• Fake Signer:
  Generates dummy signatures, which is useful for impersonation while testing. Only possible when using a network that does not enforce signature validation.
