Function call_contract 

pub fn call_contract(
    contract_id: &AccountId,
    calldata: &[u8],
) -> Result<Vec<u8>>

Invokes another contract without transferring value.

This is the legacy cross-contract call mechanism. The called contract executes with the same caller context (the original transaction sender).

Arguments

• contract_id - The 32-byte address of the contract to call
• calldata - Encoded function selector and arguments

Returns

• Ok(Vec<u8>) - The return data from the called contract
• Err(Error) - If the call fails or the contract doesn’t exist

Gas

The called contract shares the remaining gas budget of the current execution.

Example

use truthlinked_sdk::call;

let token_contract = [0x12; 32];
let calldata = encode_balance_of(account);
let balance_bytes = call::call_contract(&token_contract, &calldata)?;
let balance = decode_u128(&balance_bytes);
