JsonRpcProvider
|
|
===============
|
|
|
|
#### **new ***ethers* . *providers* . **JsonRpcProvider**( [ url [ , aNetworkish ] ] )
|
|
|
|
Connect to a JSON-RPC API located at *url* using the *aNetworkish* network. If *url* is not specified, the default (i.e. `http://localhost:8545`) is used and if no network is specified, it will be determined automatically by querying the node.
|
|
|
|
|
|
#### Note: Connecting to a Local Node
|
|
|
|
Each node implementation is slightly different and may require specific command-line flags, configuration or settings in their UI to enable JSON-RPC, unlock accounts or expose specific APIs. Please consult their documentation.
|
|
|
|
|
|
#### *jsonRpcProvider* . **getSigner**( [ addressOrIndex ] ) => *[JsonRpcSigner](/v5/api/providers/jsonrpc-provider/#JsonRpcSigner)*
|
|
|
|
Returns a [JsonRpcSigner](/v5/api/providers/jsonrpc-provider/#JsonRpcSigner) which is managed by this Ethereum node, at *addressOrIndex*. If no *addressOrIndex* is provided, the first account (account #0) is used.
|
|
|
|
|
|
#### *jsonRpcProvider* . **getUncheckedSigner**( [ addressOrIndex ] ) => *[JsonRpcUncheckedSigner](/v5/api/providers/jsonrpc-provider/#UncheckedJsonRpcSigner)*
|
|
|
|
|
|
|
|
#### *jsonRpcProvider* . **listAccounts**( ) => *Array< string >*
|
|
|
|
Returns a list of all account addresses managed by this provider.
|
|
|
|
|
|
#### *jsonRpcProvider* . **send**( method , params ) => *Promise< any >*
|
|
|
|
Allows sending raw messages to the provider.
|
|
|
|
This can be used for backend-specific calls, such as for debugging or specific account management.

|
|
|
|
#### *signer* . **provider** => *[JsonRpcProvider](/v5/api/providers/jsonrpc-provider/)*
|
|
|
|
The provider this signer was established from.
|
|
|
|
|
|
#### *signer* . **connectUnchecked**( ) => *[JsonRpcUncheckedSigner](/v5/api/providers/jsonrpc-provider/#UncheckedJsonRpcSigner)*
|
|
|
|
Returns a new Signer object which does not perform additional checks when sending a transaction. See [getUncheckedSigner](/v5/api/providers/jsonrpc-provider/#JsonRpcProvider-getUncheckedSigner) for more details.
|
|
|
|
|
|
#### *signer* . **sendUncheckedTransaction**( transaction ) => *Promise< string< [DataHexString](/v5/api/utils/bytes/#DataHexString)< 32 > > >*
|
|
|
|
Sends the *transaction* and returns a Promise which resolves to the opaque transaction hash.
|
|
|
|
|
|
#### *signer* . **unlock**( password ) => *Promise< boolean >*
|
|
|
|
Request the node unlock the account (if locked) using *password*.
