When deploying one contract from different private keys, they have the same address

Rust SDK
1

Hello guys, I have an issue again.
Yesterday I tried to deploy 5 tokens using rust-sdk. First, I deployed them one by one from one account, but I noticed that the addresses of the tokens are the same, it’s logical :disguised_face:

Created 5 accounts, minted them using a facet on a token to pay the network commission, collected a config and began to deploy each token from a new account

Below is the script with which I deployed, and its output. As you can see, different tokens from different accounts still have the same address.
Maybe I don’t understand something, please explain how I can deploy 5 contract instances with different addresses.

ContractIds on Fuel are deterministic. They do not depend on the nonce of the deploying address. So a contract’s ID will always be the same regardless of who deploys it or when it is deployed.

There are times when you want your contract to have a different address; this is what the salt is for.

if you want multiple instances of the same contract then use deploy_with_parameters and set the salt parameter.

In practice, it looks like this:

let contract_id_2 = Contract::deploy_with_parameters(
            "../../packages/fuels/tests/contracts/contract_test/out/debug/contract_test.bin",
            &wallet,
            TxParameters::default(),
            StorageConfiguration::default(),
            Salt::from(salt),
        )
        .await?;
