Connect Extended#

Link your Extended account to Anboto with an API key and a Stark key pair. Extended is a perp-DEX: orders are signed with a Stark key rather than an exchange secret, and your funds sit in a numbered vault. Anboto needs four values — the API key, the Stark private key, the Stark public key, and the Vault number.

Prerequisites#

  • An Extended account with onboarding complete.
  • Funds deposited on Extended.

Create the API key on Extended#

  1. Log in to your Extended account.
  2. Generate a new API key for your account.
  3. Record the API key.
  4. Record the Stark private key and Stark public key — the pair that signs your orders. Store the private key as you would any trading secret; Anboto needs it to sign, and anyone holding it can trade your account.
  5. Record the Vault number of the vault holding your funds on Extended.

Permissions & IP allowlist#

  • The credentials are used for trading only — Anboto never needs the ability to withdraw funds.
  • Extended authenticates by API key and Stark signature; there is no exchange-side IP allowlist to configure for this venue.
  1. Log in to pro.anboto.xyz and open Settings (top right) → Linked Exchanges.
  2. On the Link Perp-DEX tab, select the Extended tile.
  3. Enter the API key, Stark private key, Stark public key, and Vault number, then save.

Anboto validates the credentials as soon as you save and shows an inline error if any value is invalid — check that the Stark key pair matches and the vault number is the one holding your funds.

Sub-accounts

Use Add sub account on the Extended tile to link keys for Extended sub-accounts. Sub-account names must not be main or Main.
