The PartnerAccountService creates sub-account profiles linked to the authenticated partner. It requires HMAC authentication with the account_creation scope.

​
Access

use limitless_exchange_rust_sdk::{Client, HmacCredentials};

let http = Client::builder()
    .hmac_credentials(HmacCredentials {
        token_id: token_id.to_string(),
        secret: secret.to_string(),
    })
    .build()?;

let client = Client::from_http_client(http)?;

// Use client.partner_accounts.*

​
Server wallet mode

Set create_server_wallet to create a managed wallet for the sub-account. This enables delegated signing: 
use limitless_exchange_rust_sdk::CreatePartnerAccountInput;

let account = client
    .partner_accounts
    .create_account(
        &CreatePartnerAccountInput {
            display_name: Some("user-alice".to_string()),
            create_server_wallet: Some(true),
        },
        None,
    )
    .await?;

println!("{}", account.profile_id);
println!("{}", account.account);
New server wallets often need a short backend provisioning window before the first delegated trade. A delay of a few seconds is normal.

​
EOA mode

For externally-owned accounts, pass ownership-verification headers: 
use limitless_exchange_rust_sdk::{
    CreatePartnerAccountEoaHeaders, CreatePartnerAccountInput,
};

let account = client
    .partner_accounts
    .create_account(
        &CreatePartnerAccountInput {
            display_name: Some("user-bob".to_string()),
            create_server_wallet: Some(false),
        },
        Some(&CreatePartnerAccountEoaHeaders {
            account: "0x5aAeb6053F3E94C9b9A09f33669435E7Ef1BeAed".to_string(),
            signing_message: "0x...".to_string(),
            signature: "0x...".to_string(),
        }),
    )
    .await?;

​
Validation

  • display_name is optional and capped at 44 characters
  • when create_server_wallet is not Some(true), EOA headers are required
  • the SDK validates display_name length locally before sending the request
  • 409 Conflict is returned if a profile already exists for the target address
Server-wallet sub-accounts and EOA sub-accounts use different signing models. Use server-wallet mode for delegated signing, and EOA mode when the end user will sign orders themselves.
