Methods

addSigner

▸ addSigner(params: object): Account

Defined in src/Polymesh.ts:745

Adds a new signing key to the SDK instance. This will not change the current signer. For that, you must explicitly call setSigner

Parameters:

▪ params: object

Name	Type	Description
accountSeed	string	hex seed of the account

Returns: Account

▸ addSigner(params: object): Account

Defined in src/Polymesh.ts:753

Adds a new signing key to the SDK instance. This will not change the current signer. For that, you must explicitly call setSigner

Parameters:

▪ params: object

Name	Type	Description
accountMnemonic	string	account mnemonic

Returns: Account

▸ addSigner(params: object): Account

Defined in src/Polymesh.ts:761

Adds a new signing key to the SDK instance. This will not change the current signer. For that, you must explicitly call setSigner

Parameters:

▪ params: object

Name	Type	Description
accountUri	string	account URI

Returns: Account

claimClassicTicker

▸ claimClassicTicker(args: ClaimClassicTickerParams, opts?: ProcedureOpts): Promise‹TransactionQueue‹TickerReservation››

Defined in src/Polymesh.ts:384

Claim a ticker symbol that was reserved in Polymath Classic (Ethereum). The Ethereum account that owns the ticker must sign a special message that contains the DID of the Identity that will own the ticker in Polymesh, and provide the signed data to this call

note this method is of type ProcedureMethod, which means you can call claimClassicTicker.checkAuthorization on it to see whether the Current Account has the required permissions to run it

Parameters:

Name	Type
args	ClaimClassicTickerParams
opts?	ProcedureOpts

Returns: Promise‹TransactionQueue‹TickerReservation››

disconnect

▸ disconnect(): Promise‹void›

Defined in src/Polymesh.ts:735

Disconnect the client and close all open connections and subscriptions

note the SDK will become unusable after this operation. It will throw an error when attempting to access any chain or middleware data. If you wish to continue using the SDK, you must create a new instance by calling connect

Returns: Promise‹void›
