Request to create a transaction

POST /1.0/client/create-transaction. Accepts the following parameters:

Parametrs	Description
networkFrom (string, required)	departure network symbol (for example, Ethereum - ETH, Polygon - POL etc.)
networkTo (string, required)	destination network symbol (similar to networkFrom)
cryptoFrom	departure token symbol (for example, Ethereum - ETH, USDT - USDT etc.)
cryptoTo (string, required)	destination token symbol (similar cryptoFrom)
address (string, required)	the address from which tokens are sent in the departure network, as well as the address to which the tokens arrive in the destination network (at the moment, the address is the same, but we plan to separate these parameters)
amount (string, required)	the number of tokens to be sent from the departure network, accepts the amount in the minimum unit (for example, the decimal of Ethereum is 18, so in order to send 1 ETH, you should enter 1000000000000000000; the decimal of USDT is 6, so in order to send 100 USDT you should enter 100000000).

This call creates a new transaction in the system and returns the transfer data.
