### Retrieving Safe Singleton Deployments (V1) - TypeScript

Source: https://github.com/safe-global/safe-deployments/blob/main/README.md

Demonstrates how to use V1 methods like `getSafeSingletonDeployment` and `getSafeL2SingletonDeployment` to retrieve a single Safe contract deployment. Examples show fetching the latest version, unreleased versions, or versions specific to a network or version number. These methods return a `SingletonDeployment` object or `undefined`.

```TypeScript
const safeSingleton = getSafeSingletonDeployment();

// Returns latest contract version, even if not finally released yet
const safeSingletonNightly = getSafeSingletonDeployment({ released: undefined });

// Returns released contract version for specific network
const safeSingletonGörli = getSafeSingletonDeployment({ network: '5' });

// Returns released contract version for specific version
const safeSingleton100 = getSafeSingletonDeployment({ version: '1.0.0' });

// Version with additional events used on L2 networks
const safeL2Singleton = getSafeL2SingletonDeployment();
```

### Retrieving Handler Deployments (V1) - TypeScript

Source: https://github.com/safe-global/safe-deployments/blob/main/README.md

Provides examples of retrieving handler contract deployments using the V1 methods `getDefaultCallbackHandlerDeployment` and `getCompatibilityFallbackHandlerDeployment`. These functions return a single `SingletonDeployment` object or `undefined`.

```TypeScript
const callbackHandler = getDefaultCallbackHandlerDeployment();

const compatHandler = getCompatibilityFallbackHandlerDeployment();
```

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

### Retrieving Handler Deployments (V2) - TypeScript

Source: https://github.com/safe-global/safe-deployments/blob/main/README.md

Provides examples of retrieving handler contract deployments using the V2 methods `getDefaultCallbackHandlerDeployments` and `getCompatibilityFallbackHandlerDeployments`. These functions return a `SingletonDeployment` object (potentially with multiple network addresses) or `undefined`.

```TypeScript
const callbackHandler = getDefaultCallbackHandlerDeployments();

const compatHandler = getCompatibilityFallbackHandlerDeployments();
```

### Retrieving Safe Singleton Deployments (V2) - TypeScript

Source: https://github.com/safe-global/safe-deployments/blob/main/README.md

Demonstrates how to use V2 methods like `getSafeSingletonDeployments` and `getSafeL2SingletonDeployments` to retrieve Safe contract deployments. These methods return a `SingletonDeployment` object (potentially with multiple network addresses) or `undefined`, supporting options for latest, unreleased, network-specific, or version-specific lookups.

```TypeScript
const safeSingleton = getSafeSingletonDeployments();

// Returns latest contract version, even if not finally released yet
const safeSingletonNightly = getSafeSingletonDeployments({ released: undefined });

// Returns released contract version for specific network
const safeSingletonGörli = getSafeSingletonDeployments({ network: '5' });

// Returns released contract version for specific version
const safeSingleton100 = getSafeSingletonDeployments({ version: '1.0.0' });

// Version with additional events used on L2 networks
const safeL2Singleton = getSafeL2SingletonDeployments();
```

### Retrieving Library Deployments (V2) - TypeScript

Source: https://github.com/safe-global/safe-deployments/blob/main/README.md

Illustrates how to fetch various library contract deployments using their respective V2 getter functions: `getMultiSendDeployments`, `getMultiSendCallOnlyDeployments`, `getCreateCallDeployments`, and `getSignMessageLibDeployments`. Each returns a `SingletonDeployment` object (potentially with multiple network addresses) or `undefined`.

```TypeScript
const multiSendLib = getMultiSendDeployments();

const multiSendCallOnlyLib = getMultiSendCallOnlyDeployments();

const createCallLib = getCreateCallDeployments();

const signMessageLib = getSignMessageLibDeployments();
```

### Retrieving Proxy Factory Deployment (V2) - TypeScript

Source: https://github.com/safe-global/safe-deployments/blob/main/README.md

Shows how to retrieve the Proxy Factory contract deployment using the V2 method `getProxyFactoryDeployments`. This method returns a `SingletonDeployment` object (potentially with multiple network addresses) or `undefined`.

```TypeScript
const proxyFactory = getProxyFactoryDeployments();
```

### SingletonDeployment Interface Definition (V2) - TypeScript

Source: https://github.com/safe-global/safe-deployments/blob/main/README.md

Defines the structure of the SingletonDeployment object returned by V2 methods. Similar to V1, but the `networkAddresses` field is updated to `Record<string, string | string[]>` to accommodate networks where a contract might have multiple valid deployment addresses.

```TypeScript
export interface SingletonDeployment {
  // The default address of the deployment.
  defaultAddress: string;

  // Indicates if the deployment is released.
  released: boolean;

  // The name of the contract.
  contractName: string;

  // The version of the deployment.
  version: string;

  // The address & hash of the contract code, where the key is the deployment type.
  // There could be multiple deployment types: canonical, eip155, zksync
  // Possible addresses per version:
  // 1.0.0: canonical
  // 1.1.1: canonical
  // 1.2.0: canonical
  // 1.3.0: canonical, eip155, zksync
  // 1.4.1: canonical, zksync
  // Ex: deployments: { "canonical": { "codeHash": "0x1234", "address": "0x5678"}}
  deployments: Record<string, { address: string; codeHash: string }>;

  // A record of network addresses, where the key is the network identifier and the value is the address.
  networkAddresses: Record<string, string | string[]>;

  // The ABI (Application Binary Interface) of the contract.
  abi: any[];
}
```

### SingletonDeployment Interface Definition (V1) - TypeScript

Source: https://github.com/safe-global/safe-deployments/blob/main/README.md

Defines the structure of the SingletonDeployment object returned by V1 methods. This object contains details about a specific contract deployment, including its default address, release status, name, version, code hashes per deployment type, network-specific addresses, and ABI. The networkAddresses field in V1 is a simple string-to-string map.

```TypeScript
export interface SingletonDeployment {
  // The default address of the deployment.
  defaultAddress: string;

  // Indicates if the deployment is released.
  released: boolean;

  // The name of the contract.
  contractName: string;

  // The version of the deployment.
  version: string;

  // The address & hash of the contract code, where the key is the deployment type.
  // There could be multiple deployment types: canonical, eip155, zksync
  // Possible addresses per version:
  // 1.0.0: canonical
  // 1.1.1: canonical
  // 1.2.0: canonical
  // 1.3.0: canonical, eip155, zksync
  // 1.4.1: canonical, zksync
  // Ex: deployments: { "canonical": { "codeHash": "0x1234", "address": "0x5678"}}
  deployments: Record<string, { address: string; codeHash: string }>;

  // A record of network addresses, where the key is the network identifier and the value is the address.
  networkAddresses: Record<string, string>;

  // The ABI (Application Binary Interface) of the contract.
  abi: any[];
}
