Returns new () => Web3BatchRequest
Returns Web3BatchRequest
accountProvider
Returns undefined | Web3AccountProvider<Web3BaseWalletAccount>

The blockHeaderTimeout is used over socket-based connections. This option defines the amount seconds it should wait for
'newBlockHeaders'
event before falling back to polling to fetch transaction receipt. Default is10
seconds.Returns number

or both within your contract. This will affect the contracts send, call and estimateGas methods Default isdata
.Returns input | data | both
Will set the contractDataInputFill
Parameters
val: input | data | both
Returns void
currentProvider
Will return the current provider. (The same as
provider
)Returns undefined | Web3BaseProvider<API>
Returns the current provider

Returns undefined | CustomTransactionSchema
Parameters
schema: undefined | CustomTransactionSchema
Returns void
defaultAccount
This default address is used as the default
from
property, if nofrom
property is specified in for the following methods:- web3.eth.sendTransaction()

- myContract.methods.myMethod().send()
Returns undefined | string
Will set the default account.
Parameters
val: undefined | string
Returns void
defaultBlock
The default block is used for certain methods. You can override it by passing in the defaultBlock as last parameter. The default value is

Returns BlockNumberOrTag
Will set the default block.
- A block number
"earliest"
- String: The genesis block"latest"
- String: The latest block (current head of the blockchain)"pending"

- String: (For POS networks) The finalized block is one which has been accepted as canonical by greater than 2/3 of validators"safe"
- String: (For POS networks) The safe head block is one which under normal network conditions, is expected to be included in the canonical chain. Under normal network conditions the safe head and the actual tip of the chain will be equivalent (with safe head trailing only by a few seconds). Safe heads will be less likely to be reorged than the proof of work network's latest blocks.

Extend this class when creating a plugin that makes use of EthExecutionAPI, or depends on other Web3 packages (such as
web3-eth-contract
) that depend on EthExecutionAPI.To add type support for RPC methods to the Web3RequestManager (in addition to EthExecutionAPI), define a Web3APISpec and pass it as a generic to Web3PluginBase like so:
