The deploy module provides types and functions for deploying contracts, uploading contract code, and managing contract lifecycles.

​
Overview

Contracts are deployed with a deterministic address derived from a deployer address and salt. Access deployment functions through env.deployer() in your contracts.

​
Types

​
Deployer

Provides access to contract deployment functions. 
pub struct Deployer {
    // ...
}
Obtain via env.deployer() in contract code.

​
DeployerWithAddress

A deployer configured with a specific address and salt for deterministic contract deployment. 
pub struct DeployerWithAddress {
    // ...
}

​
DeployerWithAsset

A deployer for Stellar Asset Contracts. 
pub struct DeployerWithAsset {
    // ...
}

​
Deployer Methods

​
with_current_contract

Creates a deployer that derives contract IDs from the current contract and provided salt. 
pub fn with_current_contract(
    &self,
    salt: impl IntoVal<Env, BytesN<32>>
) -> DeployerWithAddress
Example: 
use soroban_sdk::{contract, contractimpl, Env, BytesN};

#[contract]
pub struct Contract;

#[contractimpl]
impl Contract {
    pub fn deploy(env: Env, wasm_hash: BytesN<32>) {
        let salt = [0u8; 32];
        let deployer = env.deployer().with_current_contract(salt);
        let contract_address = deployer.deploy_v2(wasm_hash, ());
    }
}

​
with_address

Creates a deployer that derives contract IDs from a specific address and salt. 
pub fn with_address(
    &self,
    address: Address,
    salt: impl IntoVal<Env, BytesN<32>>
) -> DeployerWithAddress
Note: The deployer address must authorize all deployments.

​
with_stellar_asset

Creates a deployer for a Stellar Asset Contract. 
pub fn with_stellar_asset(
    &self,
    serialized_asset: impl IntoVal<Env, Bytes>
) -> DeployerWithAsset
Parameters:
  • serialized_asset - XDR-serialized Stellar Asset

​
upload_contract_wasm

Uploads contract Wasm code to the network. 
pub fn upload_contract_wasm(
    &self,
    contract_wasm: impl IntoVal<Env, Bytes>
) -> BytesN<32>
Returns: Hash of the uploaded Wasm that can be used for deployment. Example: 
use soroban_sdk::{Env, BytesN};

const WASM: &[u8] = include_bytes!("contract.wasm");

#[test]
fn test() {
    let env = Env::default();
    let wasm_hash = env.deployer().upload_contract_wasm(WASM);
    // Use wasm_hash for deployment
}

​
update_current_contract_wasm

Replaces the current contract’s executable with new Wasm. 
pub fn update_current_contract_wasm(
    &self,
    wasm_hash: impl IntoVal<Env, BytesN<32>>
)
Note: The Wasm must already be uploaded. The update takes effect after the invocation successfully completes.

​
extend_ttl

Extends the TTL (Time To Live) of contract instance and code. 
pub fn extend_ttl(
    &self,
    contract_address: Address,
    threshold: u32,
    extend_to: u32
)
Parameters:
  • contract_address - Contract to extend TTL for
  • threshold - Only extend if current TTL is below this
  • extend_to - New TTL value in ledgers
Extends both instance and code TTL. Either or both may be extended depending on current TTL values.

​
extend_ttl_for_contract_instance

Extends only the contract instance TTL. 
pub fn extend_ttl_for_contract_instance(
    &self,
    contract_address: Address,
    threshold: u32,
    extend_to: u32
)

​
extend_ttl_for_code

Extends only the contract code TTL. 
pub fn extend_ttl_for_code(
    &self,
    contract_address: Address,
    threshold: u32,
    extend_to: u32
)

​
DeployerWithAddress Methods

​
deployed_address

Returns the deterministic address where the contract will be deployed. 
pub fn deployed_address(&self) -> Address
Can be called before or after deployment since addresses are deterministic. Example: 
use soroban_sdk::{contract, contractimpl, Env, Address};

#[contract]
pub struct Contract;

#[contractimpl]
impl Contract {
    pub fn get_deploy_address(env: Env) -> Address {
        let salt = [1u8; 32];
        let deployer = env.deployer().with_current_contract(salt);
        deployer.deployed_address()
    }
}

​
deploy_v2

Deploys a contract with the specified Wasm hash and constructor arguments. 
pub fn deploy_v2<A>(
    &self,
    wasm_hash: impl IntoVal<Env, BytesN<32>>,
    constructor_args: A
) -> Address
where
    A: ConstructorArgs
Parameters:
  • wasm_hash - Hash of uploaded Wasm code
  • constructor_args - Arguments for the contract constructor (use () for none)
Returns: Address of the deployed contract. Example with constructor: 
use soroban_sdk::{contract, contractimpl, Env, BytesN};

#[contract]
pub struct Contract;

#[contractimpl]
impl Contract {
    pub fn deploy_with_args(env: Env, wasm_hash: BytesN<32>) {
        let salt = [1u8; 32];
        let deployer = env.deployer().with_current_contract(salt);
        // Deploy with constructor arguments
        let address = deployer.deploy_v2(wasm_hash, (1_u32, 2_i64));
    }
}

​
deploy (deprecated)

#[deprecated(note = "use deploy_v2")]
pub fn deploy(
    &self,
    wasm_hash: impl IntoVal<Env, BytesN<32>>
) -> Address
Use deploy_v2 instead.

​
DeployerWithAsset Methods

​
deployed_address

Returns the deterministic address for the Stellar Asset Contract. 
pub fn deployed_address(&self) -> Address

​
deploy

Deploys the Stellar Asset Contract. 
pub fn deploy(&self) -> Address

​
Examples

​
Deploy Without Constructor

use soroban_sdk::{contract, contractimpl, BytesN, Env};

const WASM: &[u8] = include_bytes!("contract.wasm");

#[contract]
pub struct Contract;

#[contractimpl]
impl Contract {
    pub fn deploy(env: Env, wasm_hash: BytesN<32>) -> Address {
        let salt = [0u8; 32];
        let deployer = env.deployer().with_current_contract(salt);
        deployer.deploy_v2(wasm_hash, ())
    }
}

​
Deploy With Constructor

use soroban_sdk::{contract, contractimpl, BytesN, Env};

#[contract]
pub struct Contract;

#[contractimpl]
impl Contract {
    pub fn deploy_with_init(
        env: Env,
        wasm_hash: BytesN<32>,
        admin: Address,
        amount: i128
    ) -> Address {
        let salt = [0u8; 32];
        let deployer = env.deployer().with_current_contract(salt);
        deployer.deploy_v2(wasm_hash, (admin, amount))
    }
}

​
Get Address Before Deploying

use soroban_sdk::{contract, contractimpl, Env, Address};

#[contract]
pub struct Contract;

#[contractimpl]
impl Contract {
    pub fn get_address(env: Env) -> Address {
        let salt = [0u8; 32];
        let deployer = env.deployer().with_current_contract(salt);
        // Get address without deploying
        deployer.deployed_address()
    }
}

​
Test Utilities

When the testutils feature is enabled, additional functions are available:

​
get_contract_instance_ttl

Gets the TTL of a contract instance in test environments. 
pub fn get_contract_instance_ttl(&self, contract: &Address) -> u32

​
get_contract_code_ttl

Gets the TTL of contract code in test environments. 
pub fn get_contract_code_ttl(&self, contract: &Address) -> u32
