Account

class stellar_sdk.account.Account(account, sequence, raw_data=None)[source]

The Account object represents a single account on the Stellar network and its sequence number.

Account tracks the sequence number as it is used by TransactionBuilder.

Normally, you can get an Account instance through stellar_sdk.server.Server.load_account() or stellar_sdk.server_async.ServerAsync.load_account().

An example:

from stellar_sdk import Keypair, Server

server = Server(horizon_url="https://horizon-testnet.stellar.org")
source = Keypair.from_secret("SBFZCHU5645DOKRWYBXVOXY2ELGJKFRX6VGGPRYUWHQ7PMXXJNDZFMKD")
# `account` can also be a muxed account
source_account = server.load_account(account=source.public_key)

See Accounts for more information.

Parameters

account (Union[str, MuxedAccount]) – Account Id of the account (ex. "GB3KJPLFUYN5VL6R3GU3EGCGVCKFDSD7BEDX42HWG5BWFKB3KQGJJRMA") or muxed account (ex. "MBZSQ3YZMZEWL5ZRCEQ5CCSOTXCFCMKDGFFP4IEQN2KN6LCHCLI46AAAAAAAAAAE2L2QE")
sequence (int) – Current sequence number of the account.

The Operation object, which represents an operation on Stellar’s network.

An operation is an individual command that mutates Stellar’s ledger. It is typically rolled up into a transaction (a transaction is a list of operations with additional metadata).

Operations are executed on behalf of the source account specified in the transaction, unless there is an override defined for the operation.

For more on operations, see Stellar’s documentation on operations as well as Stellar’s List of Operations, which includes information such as the security necessary for a given operation, as well as information about when validity checks occur on the network.

The Operation class is typically not used, but rather one of its subclasses is typically included in transactions.

Parameters: source (Union[MuxedAccount, str, None]) – The source account for the operation. Defaults to the transaction’s source account.

Returns: The source account from account the operation xdr object.

static to_xdr_amount(value)[source]

Converts an amount to the appropriate value to send over the network as a part of an XDR object.

Each asset amount is encoded as a signed 64-bit integer in the XDR structures. An asset amount unit (that which is seen by end users) is scaled down by a factor of ten million (10,000,000) to arrive at the native 64-bit integer representation. For example, the integer amount value 25,123,456 equals 2.5123456 units of the asset. This scaling allows for seven decimal places of precision in human-friendly amount units.

This static method correctly multiplies the value by the scaling factor in order to come to the integer value used in XDR structures.

See Stellar’s documentation on Asset Precision for more information.

CreatePassiveSellOffer

class stellar_sdk.operation.CreatePassiveSellOffer(selling, buying, amount, price, source=None)[source]

The CreatePassiveSellOffer object, which represents a CreatePassiveSellOffer operation on Stellar’s network.

A passive sell offer is an offer that does not act on and take a reverse offer of equal price. Instead, they only take offers of lesser price. For example, if an offer exists to buy 5 BTC for 30 XLM, and you make a passive sell offer to buy 30 XLM for 5 BTC, your passive sell offer does not take the first offer.

Note that regular offers made later than your passive sell offer can act on and take your passive sell offer, even if the regular offer is of the same price as your passive sell offer.

Passive sell offers allow market makers to have zero spread. If you want to trade EUR for USD at 1:1 price and USD for EUR also at 1:1, you can create two passive sell offers so the two offers don’t immediately act on each other.

Once the passive sell offer is created, you can manage it like any other offer using the manage offer operation - see ManageBuyOffer for more details.
