I am trying to send 0.52 from my address to address2 and I am passing fees like below
Code:
var tx = bitcore.Transaction();
tx.from(utxos);
tx.to(address2,satoshibits); // 520000
tx.change(address);
tx.fee(fees); // 260000 in satoshi
tx.sign(privateKey);
tx.serialize();
Error:
Fee is too large: expected less than 150000 but got 260000
Anyone have an idea if I want to pass max fees then default
Code:
var tx = bitcore.Transaction();

tx.sign(privateKey);
tx.serialize();

I am using bitcore server https://github.com/bitpay/bitcore and below is the code for making a transaction
Code:
var tx = bitcore.Transaction();
tx.from(utxos);
tx.to(address2,50000);
tx.change(address);
tx.sign(privateKey);
tx.serialize();
How much transaction fees are taken for executing the above transaction.? and I want to check before the transaction goes for the execution.

Re: Private/public key generated by bitcore API issue!!! please help
it is a string "115792089237316195423570985008687907853269984665640564039457584007908834671663" or something else..?
It's the value of the moduli. It is the biggest number in the curve secp256k1 that bitcoin uses.
=2^256-2^32-2^9-2^8-2^7-2^6-2^4-1
If your generated private key is bigger than that, then you have to subtract that number from your generated key as many times as necessary, until it becomes smaller than that number.
The security of bitcoin depends on big numbers. That is the reason why the moduli has to be so big.
https://en.bitcoin.it/wiki/Secp256k1
for example :
Here is my private key ="9c63e8e2f6574c197c0626bad843eb47104adf3f01f2901aad1258936feb007e"
var newprimarykey = (9c63e8e2f6574c197c0626bad843eb47104adf3f01f2901aad1258936feb007e * 36453278) mod 115792089237316195423570985008687907853269984665640564039457584007908834671663 );
console.log('newkey = ',newprimarykey);
If i am executing this one then it'll give error :
var t1 = (9c63e8e2f6574c197c0626bad843eb47104adf3f01f2901aad1258936feb007e * 36453278);

Re: Private/public key generated by bitcore API issue!!! please help
I am a developer and faced below issue in development, so please help me 
How do I create multiple addresses based on same private/public key generated by bitcore API?
How do I create multiple addresses based on same private/public key generated by bitcore API?
You could invent a nice rule on how to generate a new private key from your private key.
Example.
You could take your private key an multiply it by any number (for example: 36453278) to get the next private key then multiply that to get the next one and so on. You can do the multiply as many times as you want to. to generate as many addresses as you need.
Just remember that we are dealing with modular arithmetic, so you need to take a mod from the result, so that it wont get bigger than the maximum allowed value.
eg:
(privkey1*36453278) mod 115792089237316195423570985008687907853269984665640564039457584007908834671663
That is basically what HD wallets do to generate many private keys from one. Except, they use a bit more complicated algorithm and sha256 hash on each result so that even a small change will create a completely different private key.
The advantage of this kind of approach is that you only need to backup your original private key and the multiplier, and not a huge list of different private keys.
it is a string "115792089237316195423570985008687907853269984665640564039457584007908834671663" or something else..?
