Expand description

API that groups methods that either send EGLD or ESDT, or that call other contracts.

Required methods

Sends EGLD to a given address, directly. Used especially for sending EGLD to regular accounts.

Sends EGLD to an address (optionally) and executes like an async call, but without callback.

Sends ESDT to an address and executes like an async call, but without callback.

Sends ESDT NFT to an address and executes like an async call, but without callback.

Sends an asynchronous call to another contract. Calling this method immediately terminates tx execution. Using it directly is generally discouraged.

The data is expected to be of the form functionName@<arg1-hex>@<arg2-hex>@.... Use a HexCallDataSerializer to prepare this field.

Deploys a new contract in the same shard. Unlike async_call_raw, the deployment is synchronous and tx execution continues afterwards. Also unlike async_call_raw, it uses an argument buffer to pass arguments If the deployment fails, Option::None is returned

Deploys a new contract in the same shard by re-using the code of an already deployed source contract. The deployment is done synchronously and the new contract’s address is returned. If the deployment fails, Option::None is returned

Upgrades a child contract of the currently executing contract. The upgrade is synchronous, and the current transaction will fail if the upgrade fails. The child contract’s new init function will be called with the provided arguments

Same shard, in-line execution of another contract.

Same shard, in-line execution of another contract. Allows the contract to specify which result range to extract as sync call result. This is a workaround to handle nested sync calls. Please do not use this method unless there is absolutely no other option. Will be eliminated after some future Arwen hook redesign. range_closure takes the number of results before, the number of results after, and is expected to return the start index (inclusive) and end index (exclusive).

Used to store data between async call and callback.

Used to store data between async call and callback.

Allows synchronously calling a local function by name. Execution is resumed afterwards. You should never have to call this function directly. Use the other specific methods instead.
