Operation

public class Operation : @unchecked Sendable

Base class for all Stellar operations.

Operations are the building blocks of Stellar transactions. Each operation represents a specific action on the Stellar network such as sending payments, creating accounts, or managing offers. Operations are grouped into transactions and submitted to the network.

You should never instantiate this class directly. Instead, use one of its subclasses that represent specific operation types. Each operation can optionally specify a source account that differs from the transaction’s source account.

Common operation types:

• PaymentOperation: Send assets between accounts
• CreateAccountOperation: Create and fund new accounts
• ChangeTrustOperation: Establish trustlines for assets
• ManageSellOfferOperation: Create or modify sell offers
• ManageBuyOfferOperation: Create or modify buy offers
• SetOptionsOperation: Configure account settings
• And many more…

Operation-level source accounts: When an operation specifies a source account, that account will be used as the source for that specific operation instead of the transaction’s source account. This is useful for multi-signature transactions or channel accounts.

Example:

// Payment operation using transaction source account
let payment1 = try PaymentOperation(
    sourceAccountId: nil,
    destinationAccountId: "GDEST...",
    asset: Asset(type: AssetType.ASSET_TYPE_NATIVE),
    amount: 100.0
)

// Payment operation using different source account
let payment2 = try PaymentOperation(
    sourceAccountId: "GSOURCE...",
    destinationAccountId: "GDEST...",
    asset: Asset(type: AssetType.ASSET_TYPE_NATIVE),
    amount: 50.0
)
