Methods
addSigner
▸ addSigner(params: object): Account
Defined in src/Polymesh.ts:711
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:719
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:727
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:353
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:
Returns: Promise‹TransactionQueue‹TickerReservation››
disconnect
▸ disconnect(): Promise‹void›
Defined in src/Polymesh.ts:701
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›
