Pull Request Overview
This PR introduces major architectural changes to support gas limit estimation throughout the MultiversX SDK, making it a key feature in v15. The PR adds automated gas estimation capabilities and modernizes the transaction building patterns by moving from the old TransactionBuilder pattern to direct Transaction creation with asynchronous factory methods.
- Addition of
GasLimitEstimatorclass for automated gas limit calculation - Conversion of all transaction factory methods from synchronous to asynchronous
- Migration from
TransactionBuilderto directTransactioncreation withBaseFactory

[nitpick] The comment mentions 'Failure to provide this parameter without an estimator may lead to runtime errors' but this is vague. Consider documenting the specific error type or condition that would occur.
| * Failure to provide this parameter without an estimator may lead to runtime errors. | |
| * Failure to provide this parameter without an estimator may result in a transaction failure | |
| * or an out-of-gas error during execution. |

Missing documentation comment explaining when gasLimit is optional and what happens when it's not provided, unlike the smart contracts resources file which includes this information.

The constructor parameter change from individual parameters (url?, kind?, clientName?) to an options object is a breaking change. Consider maintaining backward compatibility or clearly documenting this as a breaking change.

The function return type changed from Code to Uint8Array, but the function name 'loadContractCode' still suggests it returns a Code object. Consider renaming to 'loadContractBytecode' or similar to reflect the actual return type.

[nitpick] The TransactionComputer instance is created multiple times throughout the test file. Consider creating it once at the test suite level to reduce duplication and improve maintainability.
