[0.7.1] – 2022-11-09

New

  • additional logic to detect errors during making/canceling of orders

Fixed

  • optimization for first step of the makeOrder and cancelOrder

[0.7.0] – 2022-11-08

New

  • ABI 2.3 Flex Contracts version was supported.

  • makeOrder and cancelOrder now returns additional status field of type enum MakeOrderStatus representing the processing stage of the request. Can be of [STARTING, FINALIZING, SUCCESS, ERROR].

  • In case of FINALIZING status returned can be proceeded to the final result with waitForMakeOrder and waitForCancelOrder functions. Just pass the result of makeOrder/cancelOrder as the input parameter.

    Attention!!!!

    • ERROR status means the error occurred in the contract system, which means you SHOULD NOT perform retries until you solve the error reason.
    • Network errors are not resolved by makeOrder/cancelOrder methods. Wrap your code in try catch for network errors. In case of network error we suggest you to query trader info from the api to understand your state. See /examples/trader-info.ts sample

Improved

  • Added flex client balance check before trader Index Contract deploy to the deployTrader.

Fixed

  • If non-existing signer was specified then empty error message was printed.
  • make-order did not finish process in case of a full order closure.
