Class: ContractFunctionInteraction

contract.ContractFunctionInteraction

This is the class that is returned when calling e.g. contract.methods.myMethod(arg0, arg1). It contains available interactions one can call on a method, including view.

Methods

create

▸ create(opts?): Promise<TxExecutionRequest>

Create a transaction execution request that represents this call, encoded and authenticated by the user's wallet, ready to be simulated.

Parameters

Name	Type	Description
opts?	SendMethodOptions	An optional object containing additional configuration for the transaction.

Returns

Promise<TxExecutionRequest>

A Promise that resolves to a transaction instance.

Overrides

BaseContractInteraction.create

---

estimateGas

▸ estimateGas(opts?): Promise<Pick<GasSettings, "gasLimits" | "teardownGasLimits">>

Estimates gas for a given tx request and returns gas limits for it.

Parameters

Name	Type	Description
opts?	Omit<SendMethodOptions, "estimateGas" | "skipPublicSimulation">	Options.

Returns

Promise<Pick<GasSettings, "gasLimits" | "teardownGasLimits">>

Gas limits.

Inherited from

BaseContractInteraction.estimateGas

---

getFeeOptionsFromEstimatedGas

▸ getFeeOptionsFromEstimatedGas(request): Promise<undefined | { gasSettings: GasSettings ; paymentMethod: FeePaymentMethod }>

Helper method to return fee options based on the user opts, estimating tx gas if needed.

Parameters

Name	Type	Description
request	ExecutionRequestInit	Request to execute for this interaction.

Returns

Promise<undefined | { gasSettings: GasSettings ; paymentMethod: FeePaymentMethod }>

Fee options for the actual transaction.

Inherited from

BaseContractInteraction.getFeeOptionsFromEstimatedGas

---

prove

▸ prove(options?): Promise<ProvenTx>

Proves a transaction execution request and returns a tx object ready to be sent.

Parameters

Name	Type	Description
options	SendMethodOptions	optional arguments to be used in the creation of the transaction

Returns

Promise<ProvenTx>

The resulting transaction

Inherited from

BaseContractInteraction.prove

---

proveInternal

▸ proveInternal(options?): Promise<TxProvingResult>

Creates a transaction execution request, simulates and proves it. Differs from .prove in that its result does not include the wallet nor the composed tx object, but only the proving result. This object can then be used to either create a ProvenTx ready to be sent, or directly send the transaction.

Parameters

Name	Type	Description
options	SendMethodOptions	optional arguments to be used in the creation of the transaction

Returns

Promise<TxProvingResult>

The proving result.

Inherited from

BaseContractInteraction.proveInternal

---

request

▸ request(): FunctionCall

Returns an execution request that represents this operation. Useful as a building block for constructing batch requests.

Returns

FunctionCall

An execution request wrapped in promise.

---

send

▸ send(options?): SentTx

Sends a transaction to the contract function with the specified options. This function throws an error if called on an unconstrained function. It creates and signs the transaction if necessary, and returns a SentTx instance, which can be used to track the transaction status, receipt, and events.

Parameters

Name	Type	Description
options	SendMethodOptions	An optional object containing 'from' property representing the AztecAddress of the sender. If not provided, the default address is used.

Returns

SentTx

A SentTx instance for tracking the transaction status and information.

Inherited from

BaseContractInteraction.send

---

simulate

▸ simulate(options?): Promise<any>

Simulate a transaction and get its return values Differs from prove in a few important ways:

1. It returns the values of the function execution
2. It supports unconstrained, private and public functions

Parameters

Name	Type	Description
options	SimulateMethodOptions	An optional object containing additional configuration for the transaction.

Returns

Promise<any>

The result of the transaction as returned by the contract function.

---

simulateWithProfile

▸ simulateWithProfile(options?): Promise<ProfileResult>

Simulate a transaction and profile the gate count for each function in the transaction.

Parameters

Name	Type	Description
options	SimulateMethodOptions	Same options as simulate.

Returns

Promise<ProfileResult>

An object containing the function return value and profile result.
