I want to calculate the fees of a blocktrail transaction with blocktrail SDK, before making the transaction, in order to let the recipient pay fees.
Here is what I tried:
$FEES = $wallet->coinSelection(\Blocktrail\SDK\Wallet::normalizeOutputsStruct(['66f4dec6ab29cd056ce1814c6fdfee05e1524b36' =>'100000']),false,false,\Blocktrail\SDK\Wallet::FEE_STRATEGY_LOW_PRIORITY;
echo "$FEES";
$fee = $FEES['fee'];
echo "$fee";
But this don't work, it says this: Fatal error: Uncaught Blocktrail\SDK\Exceptions\BlocktrailSDKException: Address not recognized
How can I fix this error?
