### Example Contract Installation on Local Network

Source: https://github.com/casper-network/docs-redux/blob/dev/docs/developers/cli/installing-contracts.md

This example demonstrates how to install a contract named 'counter-installer.wasm' to a local NCTL network. It specifies the node address, chain name, secret key path, gas tolerance, pricing mode, and the path to the Wasm file.

```bash
casper-client put-transaction session \
--node-address http://localhost:11101 \
--chain-name casper-net-1 \
--secret-key ~/casper/casper-nctl/assets/net-1/users/user-1/secret_key.pem \
--gas-price-tolerance 10 \
--pricing-mode fixed \
--transaction-path ~/test_contracts/counter_installer.wasm \
--session-entry-point call \
--category 'install-upgrade'

### Install Contract using Casper-Client (Rust)

Source: https://github.com/casper-network/docs-redux/blob/dev/docs/developers/dapps/sdk/client-library-usage.md

This Rust example demonstrates installing a contract using the casper-client library. It requires specifying the node address, secret key path, chain name, session arguments, and payment amount. The `put_deploy` function sends the deploy to the network.

```rust
extern crate casper_client;
async fn put_deploy(){
    let maybe_rpc: &str = "";
    let verbosity: u64 = 1;
    let node_address: &str = "http://135.181.216.142:7777";
    let deploy_params: casper_client::DeployStrParams = casper_client::DeployStrParams{
        secret_key:"./sk_testnet.pem",
        timestamp:"",
        ttl:"50s",
        gas_price:"1000000000",
        chain_name:"casper", // or "casper-test"
        dependencies: Vec::new(),
        session_account: "01daad67ebbcb725e02a1955a6617512b311435a21ca6d523085aa015d2d1b473a"

    };
    // Without session args:
    // let session_args: Vec<&str> = Vec::new();
    // With session args:
    let mut session_args: Vec<&str> = Vec::new();
    session_args.push("argument:String='hello world'");
    let session_params: casper_client::SessionStrParams = casper_client::SessionStrParams::with_path("./contract.wasm", session_args, "");
    let payment_params: casper_client::PaymentStrParams = casper_client::PaymentStrParams::with_amount("10000000000");
    let result = casper_client::put_deploy(maybe_rpc_id, node_address, verbosity_level, deploy_params, session_params, payment_params).await.unwrap();
    println!("Deploy response: {:?}", result);
}

#[tokio::main]
async fn main(){
    send_transfer().await;
}
```

--------------------------------

### Install Rustup

Source: https://github.com/casper-network/docs-redux/blob/dev/condor/local-setup.md

npm i
```

--------------------------------

### Check CMake Version

Source: https://github.com/casper-network/docs-redux/blob/dev/docs/developers/prerequisites.md

Verify that CMake is installed and check its version. This command is useful after installation or upgrade to confirm the setup.

```bash
cmake --version
```

--------------------------------

### Build and Test Authorization Keys Example

Source: https://github.com/casper-network/docs-redux/blob/dev/docs/resources/advanced/list-auth-keys-tutorial.md

Commands to clone the repository, navigate to the example directory, and build the project's tests. Ensure your Rust environment is prepared.

```

--------------------------------

### Rust: Deploying Entry Point with Installer Authorization

Source: https://github.com/casper-network/docs-redux/blob/dev/docs/resources/advanced/list-auth-keys-tutorial.md

This snippet demonstrates how to construct and execute a deploy item for a contract's entry point. It specifies the contract hash, entry point name, payment, and authorization keys. Use this when the caller needs to be authorized by the installer's keys.

```rust
let contract_hash = builder
    .get_expected_account(*DEFAULT_ACCOUNT_ADDR)
    .named_keys()
    .get(CONTRACT_HASH)
    .expect("must have this entry in named keys")
    .into_hash()
    .map(ContractHash::new)
    .unwrap();

let entry_point_deploy_item = DeployItemBuilder::new()
    .with_empty_payment_bytes(runtime_args! {ARG_AMOUNT => *DEFAULT_PAYMENT})
    .with_authorization_keys(&[account_addr_1])
    .with_address(account_addr_1)
    .with_stored_session_hash(contract_hash, ENTRYPOINT, runtime_args! {})
    .build();

let entry_point_request =
    ExecuteRequestBuilder::from_deploy_item(entry_point_deploy_item).build();

builder.exec(entry_point_request).expect_success().commit();
```

### Rust: Deploying Entry Point with Multiple Authorization Keys

Source: https://github.com/casper-network/docs-redux/blob/dev/docs/resources/advanced/list-auth-keys-tutorial.md

This snippet demonstrates invoking a contract's entry point with multiple authorization keys. It constructs a deploy item specifying the contract hash, entry point, payment, and a list of authorization keys. Use this when the caller's deploy needs to be signed by multiple authorized accounts.

```rust
let entry_point_deploy_item = DeployItemBuilder::new()
    .with_empty_payment_bytes(runtime_args! {ARG_AMOUNT => *DEFAULT_PAYMENT})
    .with_authorization_keys(&[account_addr_1, *DEFAULT_ACCOUNT_ADDR])
    .with_address(account_addr_1)
    .with_stored_session_hash(contract_hash, ENTRYPOINT, runtime_args! {})
    .build();

let entry_point_request =
    ExecuteRequestBuilder::from_deploy_item(entry_point_deploy_item).build();

builder.exec(entry_point_request).expect_success().commit();
```
