allow wallet and coins object to sign using the BitGo key if the passphrase is not provided during signing Ticket: WCN-217-2
When no walletPassphrase is present in the request body or environment, pass undefined to tradingAccount.signPayload() instead of throwing. The SDK routes passphrase-less signing through KMS internally. Ticket: WCN-215-1

Commit 1: allowing trading wallet transaction signing on Trading Account Objects
make wallet passphrase optional when signing OFC transactions.
if not present, the SDK attempts to sign using the wallet's BitGo key instead.
Commit 2: allowing trading wallet transaction signing on Wallet and Coins object
The following are all of the currently valid methods to create a signature on an OFC wallet's
payloadstringofcToken.signMessage({prv}, message): encrypts the message locally using prvofcToken.signTransaction(params): signs a half signed transaction by calling the above methodwallet.baseCoin.signMessage: see abovewallet.baseCoin.signTransaction: see abovewallet.signTransaction(params): signs a half signed transaction by getting the prv through a wallet passphrase then callingthis.baseCoin.signTransactionwallet.prebuildAndSignTransaction(params): builds and sign a transaction by callingwallet.signTransactionwallet.prebuildAndSignTransaction(e.g. sendMany)wallet.toTradingAccount().signPayload: signs a half signed transaction using the wallet passphraseChanges in commit 1 address path 8 already.
For paths that creates the signature using methods of wallet object (i.e. 5-7), all of them eventually calls
wallet.signTransaction, which pass itselfthisas an argument towallet.baseCoin.signTransaction(see here), allowing us to sign via BitGo key if we add the implementation toofcTokenAs for
ofcToken.signMessage, add overloads to the method to allow SDK user to pass in the wallet object instead, which creates the signature via the BitGo key.Note that the
walletPassphraseis already an optional parameter when calling wallet level methods.
