Syntax

public static class BurnTokenExtensions

Methods

BurnTokenAsync(ConsensusClient, BurnTokenParams, Action<IConsensusContext>?)

Removes Fungible Token coins from the token's Treasury account.

Declaration

public static Task<TokenReceipt> BurnTokenAsync(this ConsensusClient client, BurnTokenParams burnParams, Action<IConsensusContext>? configure = null)

Parameters

Type	Name	Description
ConsensusClient	client	The Consensus Node Client orchestrating the burn.
BurnTokenParams	burnParams	The details identifying the token and amount to burn.
Action<IConsensusContext>	configure	Optional callback method providing an opportunity to modify the execution configuration for just this method call. It is executed prior to submitting the request to the network.

Returns

Type	Description
Task<TokenReceipt>	A transaction receipt indicating a successful operation.

Examples

// Burn 250,000 tokens from the treasury account. Like minting, burning
// requires the supply key signature.
var receipt = await client.BurnTokenAsync(token, 250_000);
Console.WriteLine($"Burn status: {receipt.Status}");
Console.WriteLine($"New circulation: {receipt.Circulation}");

Exceptions

Type	Condition
ArgumentException	If required arguments are missing or invalid.
InvalidOperationException	If required context configuration is missing.
PrecheckException	If the gateway node refused the transaction. Only a code about the transaction itself proves it did not execute; any other code leaves the outcome unknown, so settle it by its transaction id on a mirror node rather than resubmitting it (see PrecheckException).
ConsensusException	If the outcome could not be confirmed: the transaction may have executed, so settle it by its transaction id on a mirror node rather than resubmitting it.
TransactionException	If the network rejected the request as invalid or had missing data.

BurnTokenAsync(ConsensusClient, EntityId, ulong, Action<IConsensusContext>?)

Removes Fungible Token coins from the token's Treasury account.

Declaration

public static Task<TokenReceipt> BurnTokenAsync(this ConsensusClient client, EntityId token, ulong amount, Action<IConsensusContext>? configure = null)

Parameters

Type	Name	Description
ConsensusClient	client	The Consensus Node Client orchestrating the burn.
EntityId	token	The identifier of the Token to remove coins from.
ulong	amount	The amount of coins to remove (specified in the smallest denomination).
Action<IConsensusContext>	configure	Optional callback method providing an opportunity to modify the execution configuration for just this method call. It is executed prior to submitting the request to the network.

Returns

Type	Description
Task<TokenReceipt>	A transaction receipt indicating a successful operation.

Examples

// Burn 250,000 tokens from the treasury account. Like minting, burning
// requires the supply key signature.
var receipt = await client.BurnTokenAsync(token, 250_000);
Console.WriteLine($"Burn status: {receipt.Status}");
Console.WriteLine($"New circulation: {receipt.Circulation}");
