Create Account

JavaScript | Java | Go

Creates and funds a new account with the specified starting balance.

Threshold: Medium

Result: CreateAccountResult

Parameters:

Parameter Type Description
Destination account ID Account address that is created and funded.
Starting Balance integer Amount of PMN to send to the newly created account. This PMN comes from the source account.

Possible errors:

Error Code Description
CREATE_ACCOUNT_MALFORMED The destination is invalid.
CREATE_ACCOUNT_UNDERFUNDED The source account performing the command does not have enough funds to give destination the starting balance amount of PMN and still maintain its minimum PMN reserve plus satisfy its PMN selling liabilities.
CREATE_ACCOUNT_LOW_RESERVE This operation would create an account with fewer than the minimum number of PMN an account must hold.
CREATE_ACCOUNT_ALREADY_EXIST The destination account already exists.

Payment

JavaScript | Java | Go

Sends an amount in a specific asset to a destination account.

Threshold: Medium

Result: PaymentResult

Parameters:

Parameters Type Description
Destination account ID Account address that receives the payment.
Asset asset Asset to send to the destination account.
Amount integer Amount of the aforementioned asset to send.

Possible errors:

Error Code Description
PAYMENT_MALFORMED The input to the payment is invalid.
PAYMENT_UNDERFUNDED The source account (sender) does not have enough funds to send amount and still satisfy its selling liabilities. Note that if sending PMN then the sender must additionally maintain its minimum PMN reserve.
PAYMENT_SRC_NO_TRUST The source account does not trust the issuer of the asset it is trying to send.
PAYMENT_SRC_NOT_AUTHORIZED The source account is not authorized to send this payment.
PAYMENT_NO_DESTINATION The receiving account does not exist.
PAYMENT_NO_TRUST The receiver does not trust the issuer of the asset being sent. For more information, see the assets doc.
PAYMENT_NOT_AUTHORIZED The destination account is not authorized by the asset’s issuer to hold the asset.
PAYMENT_LINE_FULL The destination account (receiver) does not have sufficient limits to receive amount and still satisfy its buying liabilities.
PAYMENT_NO_ISSUER The issuer of the asset does not exist.

Path Payment Strict Send

JavaScript | Java | Go

A path payment sends an amount of a specific asset to a destination account through a path of offers. Since the asset sent (e.g., 450 PMN) can be different from the asset received (e.g, 6 BTC), path payments allow for the simultaneous transfer and conversion of currencies.

A Path Payment Strict Send allows a user to specify the amount of the asset to send. The amount received will vary based on offers in the order books. If you would like to instead specify the amount received, use the Path Payment Strict Receive operation.

A few things to note:

  • path payments don’t allow intermediate offers to be from the source account as this would yield a worse exchange rate. You’ll need to either split the path payment into two smaller path payments, or ensure that the source account’s offers are not at the top of the order book.
  • balances are settled at the very end of the operation
    • this is especially important when (Destination, Destination Asset) == (Source, Send Asset) as this provides a functionality equivalent to getting a no interest loan for the duration of the operation.
  • Destination min is a protective measure: it allows you to specify a lower bound for an acceptable conversion. If offers in the order books are not favorable enough for the operation to deliver that amount, the operation will fail.

Threshold: Medium

Result: PathPaymentStrictSendResult

Parameters:

Parameters Type Description
Send asset asset The asset deducted from the sender’s account.
Send amount integer The amount of send asset to deduct (excluding fees).
Destination account ID Account ID of the recipient.
Destination asset asset The asset the destination account receives.
Destination min integer The minimum amount of destination asset the destination account can receive.
Path list of assets The assets (other than send asset and destination asset) involved in the offers the path takes. For example, if you can only find a path from USD to EUR through PMN and BTC, the path would be USD -> PMN-> BTC -> EUR and the path field would contain PMN and BTC.

Possible errors:

Error Code Description
PATH_PAYMENT_STRICT_SEND_MALFORMED The input to this path payment is invalid.
PATH_PAYMENT_STRICT_SEND_UNDERFUNDED The source account (sender) does not have enough funds to send and still satisfy its selling liabilities. Note that if sending PMN then the sender must additionally maintain its minimum PMN reserve.
PATH_PAYMENT_STRICT_SEND_SRC_NO_TRUST The source account does not trust the issuer of the asset it is trying to send.

PATH_PAYMENT_STRICT_SEND_NO_ISSUER The issuer of one of the assets is missing.
PATH_PAYMENT_STRICT_SEND_TOO_FEW_OFFERS -۱۰ There is no path of offers connecting the send asset and destination asset. Kuknos only considers paths of length 5 or shorter.
PATH_PAYMENT_STRICT_SEND_OFFER_CROSS_SELF -۱۱ The payment would cross one of its own offers.
PATH_PAYMENT_STRICT_SEND_UNDER_DESTMIN -۱۲ The paths that could send destination amount of destination asset would fall short of destination min.

  • balances are settled at the very end of the operation
    • this is especially important when (Destination, Destination Asset) == (Source, Send Asset) as this provides a functionality equivalent to getting a no interest loan for the duration of the operation.
  • Send max is a protective measure: it allows you to specify an upper bound for an acceptable conversion. If offers in the order books are not favorable enough for the operation to succeed for less than Send max, the operation will fail.

Create Passive Sell Offer

JavaScript | Java | Go

Creates, updates, or deletes an offer to sell one asset for another, otherwise known as a "ask"
order or "offer" on a traditional orderbook, without taking a reverse offer of equal price.

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
PMN, and you make a passive offer to buy 30 PMN for 5 BTC, your passive offer does not take the
first offer. Passive offers in Kuknos are always expressed as "ask" or "offer" orders in a
traditional orderbook.

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

Passive 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 offers so the two offers don’t
immediately act on each other.

Once the passive offer is created, you can manage it like any other offer using the manage
offer
operation.

Set Options

JavaScript | Java | Go

Sets options for an account, such as setting the inflation destination or adding an additional
signer on an account.

Allows you to set multiple options on an account in a single operation, such as
changing an operation threshold and setting the flags on an account at the same time.

For more information on the options related to signing, see our docs on
multi-sig.

When updating signers or other thresholds, the threshold of this operation is High.

Threshold: Medium or High

Result: SetOptionsResult

Parameters:

Parameters Type Description
Inflation Destination account ID Account of the inflation destination.
Clear flags integer Indicates which flags to clear. For details about the flags, please refer to the accounts doc. The bit mask integer subtracts from the existing flags of the account. This allows for setting specific bits without knowledge of existing flags.
Set flags integer Indicates which flags to set. For details about the flags, please refer to the accounts doc. The bit mask integer adds onto the existing flags of the account. This allows for setting specific bits without knowledge of existing flags.
Master weight integer A number from 0-255 (inclusive) representing the weight of the master key. If the weight of the master key is updated to 0, it is effectively disabled.
Low threshold integer A number from 0-255 (inclusive) representing the threshold this account sets on all operations it performs that have a low threshold.
Medium threshold integer A number from 0-255 (inclusive) representing the threshold this account sets on all operations it performs that have a medium threshold.

Home domain string Sets the home domain of an account. See Federation.
Signer {Public Key, weight} Add, update, or remove a signer from an account. Signer weight is a number from 0-255 (inclusive). The signer is deleted if the weight is 0.

Possible errors:

Error Code Description
SET_OPTIONS_LOW_RESERVE This account does not have enough PMN to satisfy the minimum PMN reserve increase caused by adding a subentry and still satisfy its PMN selling liabilities. For every new signer added to an account, the minimum reserve of PMN that account must hold increases.
SET_OPTIONS_TOO_MANY_SIGNERS ۲۰ is the maximum number of signers an account can have, and adding another signer would exceed that.
SET_OPTIONS_BAD_FLAGS The flags set and/or cleared are invalid by themselves or in combination.
SET_OPTIONS_INVALID_INFLATION The destination account set in the inflation field does not exist.
SET_OPTIONS_CANT_CHANGE This account can no longer change the option it wants to change.

SET_OPTIONS_INVALID_HOME_DOMAIN Home domain is malformed.

Change Trust

JavaScript | Java | Go

Creates, updates, or deletes a trustline. For more on trustlines, please refer to the assets documentation.

To delete an existing trustline, set Line to the asset of the trustline, and Limit to ۰.

Threshold: Medium

Result: ChangeTrustResult

Parameters Type Description
Line asset The asset of the trustline. For example, if a user extends a trustline of up to 200 USD to an anchor, the line is USD:anchor.
Limit integer The limit of the trustline. In the previous example, the limit would be 200.

Possible errors:

Error Code Description
CHANGE_TRUST_MALFORMED The input to this operation is invalid.
CHANGE_TRUST_NO_ISSUER The issuer of the asset cannot be found.
CHANGE_TRUST_INVALID_LIMIT The limit is not sufficient to hold the current balance of the trustline and still satisfy its buying liabilities.

CHANGE_TRUST_SELF_NOT_ALLOWED The source account attempted to create a trustline for itself, which is not allowed.

Allow Trust

JavaScript | Java | Go

Updates the authorized flag of an existing trustline. This can only be called by the issuer of a trustline’s asset, and only when AUTHORIZATION REQUIRED (at the minimum) has been set on the issuer’s account.

The issuer can only clear the authorized flag if the issuer has the AUTH_REVOCABLE_FLAG set. Otherwise, the issuer can only set the authorized flag.

If the issuer clears the authorized flag, all offers owned by the trustor that are either selling type or buying type will be deleted. (Protocol v10 and above)

Threshold: Low

Result: AllowTrustResult

Parameters Type Description
Trustor account ID The account of the recipient of the trustline.
Type asset code The 4 or 12 character-maximum asset code of the trustline the source account is authorizing. For example, if an issuing account wants to allow another account to hold its USD credit, the type is USD.
Authorize boolean Flag indicating whether the trustline is authorized.

Possible errors:

Error Code Description
ALLOW_TRUST_MALFORMED The asset specified in type is invalid. In addition, this error happens when the native asset is specified.
ALLOW_TRUST_NO_TRUST_LINE The trustor does not have a trustline with the issuer performing this operation.
ALLOW_TRUST_TRUST_NOT_REQUIRED The source account (issuer performing this operation) does not require trust. In other words, it does not have the flag AUTH_REQUIRED_FLAG set.
ALLOW_TRUST_CANT_REVOKE The source account is trying to revoke the trustline of the trustor, but it cannot do so.
ALLOW_TRUST_SELF_NOT_ALLOWED The source account attempted to allow a trustline for itself, which is not allowed because an account cannot create a trustline with itself.

Account Merge

JavaScript | Java | Go

Transfers the native balance (the amount of PMN an account holds) to another account and removes the source account from the ledger.

Threshold: High

Result: AccountMergeResult

Parameters Type Description
Destination account ID The account that receives the remaining PMN balance of the source account.

Possible errors:

Error Code Description
ACCOUNT_MERGE_MALFORMED The operation is malformed because the source account cannot merge with itself. The destination must be a different account.
ACCOUNT_MERGE_NO_ACCOUNT The destination account does not exist.
ACCOUNT_MERGE_IMMUTABLE_SET The source account has AUTH_IMMUTABLE flag set.
ACCOUNT_MERGE_HAS_SUB_ENTRIES The source account has trust lines/offers.
ACCOUNT_MERGE_SEQNUM_TOO_FAR Source’s account sequence number is too high. It must be less than (ledgerSeq << 32) = (ledgerSeq * 0x100000000). (protocol version 10 and above)
ACCOUNT_MERGE_DEST_FULL The destination account cannot receive the balance of the source account and still satisfy its paymon buying liabilities. (protocol version 10 and above)

Inflation

JavaScript | Java | Go

Runs the inflation process for the entire Kuknos network.

Anyone can submit the Inflation operation that triggers the inflation process on the Kuknos
Network. Because it can only be run once a week, this operation will fail if the network has
already had inflation processed within the past week.

Threshold: Low

Result: InflationResult

Possible errors:

Error Code Description
INFLATION_NOT_TIME Inflation only runs once a week. This failure means it is not time for a new inflation round yet.

Manage Data

JavaScript | Java | Go

Sets, modifies, or deletes a data entry (name/value pair) that is attached to a particular account.

An account can have a large amount of data entries attached to it (subject to sub-entry limits for
an account). Each data entry increases the minimum balance (via the base reserve) needed to be held
by the account.

Data entries can be used for storing application-specific data on the Kuknos Network. They are not
used by the core Kuknos Protocol.

Threshold: Medium

Result: ManageDataResult

Parameters Type Description
Name string String up to 64 bytes long. If this is a new Name it will add the given name/value pair to the account. If this Name is already present then the associated value will be modified.
Value binary data (optional) If not present then the existing Name will be deleted. If present then this value will be set in the DataEntry. Up to 64 bytes long.

Possible errors:

Error Code Description
MANAGE_DATA_NOT_SUPPORTED_YET The network hasn’t moved to this protocol change yet. This failure means the network doesn’t support this feature yet.
MANAGE_DATA_NAME_NOT_FOUND Trying to remove a Data Entry that isn’t there. This will happen if Name is set (and Value isn’t) but the Account doesn’t have a DataEntry with that Name.
MANAGE_DATA_LOW_RESERVE This account does not have enough PMN to satisfy the minimum PMN reserve increase caused by adding a subentry and still satisfy its PMN selling liabilities. For every new DataEntry added to an account, the minimum reserve of PMN that account must hold increases.
MANAGE_DATA_INVALID_NAME Name not a valid string.

Bump Sequence

JavaScript | Java | Go

Only available in Kuknos Protocol >= v10

Bumps forward the sequence number of the source account to the given sequence number.

This operation invalidates any transactions with a smaller sequence number, and is
often utilized in complex contracting scenarios.

If the specified bumpTo sequence number is greater than the source account’s sequence number,
the account’s sequence number is updated with that value, otherwise it’s not modified.

Threshold: Low

Result: BumpSequenceResult

Parameters Type Description
bumpTo SequenceNumber desired value for the operation’s source account sequence number.

Possible errors:

Error Code Description
BUMP_SEQUENCE_BAD_SEQ The specified bumpTo sequence number is not a valid sequence number. It must be between 0 and INT64_MAX (۹۲۲۳۳۷۲۰۳۶۸۵۴۷۷۵۸۰۷ or 0x7fffffffffffffff).
