getTransactionReceipt

▸ getTransactionReceipt(txHash, iteration?): any

Given a transaction hash, it returns the transaction receipt. If this function is called before the transaction is mined, it will iterate a few times in order to wait for the transaction to be mined.

Parameters

Name	Type	Default value	Description
`txHash`	`0x${string}`	`undefined`	the transaction hash
`iteration`	`number`	`1`	the iteration number

Returns

any

the transaction receipt

loadContract

▸ loadContract(contractAddress, abi): Promise<{ abi: Abi ; address: `0x${string}` ; createEventFilter: {} ; estimateGas: {} & {} ; getEvents: {} ; read: {} ; simulate: {} ; watchEvent: {} ; write: {} }>

Given an already deployed contract address and the ABI, it returns the contract instance.

Parameters

Name	Type	Description
`contractAddress`	`string`	the contract address
`abi`	`Abi`	the contract artifact

Returns

Promise<{ abi: Abi ; address: `0x${string}` ; createEventFilter: {} ; estimateGas: {} & {} ; getEvents: {} ; read: {} ; simulate: {} ; watchEvent: {} ; write: {} }>
