In solidity (ethereum) one needs the contract address to call that contract.
contract KittyInterface {
function getKitty(uint256 _id) external view returns (
bool isGestating,
bool isReady,
uint256 cooldownIndex,
uint256 nextActionAt,
uint256 siringWithId,
uint256 birthTime,
uint256 matronId,
uint256 sireId,
uint256 generation,
uint256 genes
);
}
contract ZombieFeeding is ZombieFactory {
address ckAddress = 0x06012c8cf97BEaD5deAe237070F9587f8E7A266d;
KittyInterface kittyContract = KittyInterface(ckAddress);
Can I do that in near protocol? The examples in near are something different which requires supplying the wasm file. https://github.com/near-examples/rust-high-level-cross-contract
pub fn deploy_status_message(&self, account_id: String, amount: u64) {
Promise::new(account_id)
.create_account()
.transfer(amount as u128)
.add_full_access_key(env::signer_account_pk())
.deploy_contract(
include_bytes!("../status-message-contract/status_message.wasm").to_vec(),
);
}
Also, I am getting errors while using the high level cross contract code. https://gateway.ipfs.io/ipfs/QmPvcjeEE5PJvaJNN2axgKVWGbWVEQCe9q4e95t9NCeGFt/
Take a look at the lockup contract example instead. It uses the following:
ext_whitelist::is_whitelisted(
staking_pool_account_id.clone(),
&self.staking_pool_whitelist_account_id,
NO_DEPOSIT,
gas::whitelist::IS_WHITELISTED,
)
.then(ext_self_owner::on_whitelist_is_whitelisted(
staking_pool_account_id,
&env::current_account_id(),
NO_DEPOSIT,
gas::owner_callbacks::ON_WHITELIST_IS_WHITELISTED,
))
The first call interface is (<arg_0>, <arg_1>, ..., <arg_n>, <ACCOUNT_ID>, <ATTACHED_DEPOSIT>, <ATTACHED_GAS>)
<arg_0>, <arg_1>, ..., <arg_n> - arguments from the interface defined below<ACCOUNT_ID> - the account where the contract to call is deployed<ATTACHED_DEPOSIT> - the amount in yocto-NEAR to attach to the call<ATTACHED_GAS> - the amount of Gas to pass to the callIt later attached a callback to the first promise using .then. The callback is just another async function call.
The high-level interface ext_whitelist is defined like this:
#[ext_contract(ext_whitelist)]
pub trait ExtStakingPoolWhitelist {
fn is_whitelisted(&self, staking_pool_account_id: AccountId) -> bool;
}
