ICO Linked to Staking: Configure Caramel + UBE

Overview and Requirements

You can configure an ICO so that purchased tokens are not delivered directly to the contributor. Instead, after the ICO ends, tokens are automatically staked in a UBE staking contract for a defined lock period (e.g., 90 or 180 days).

Important: For this configuration to be effective, the staking contract should have a high penalization (50% or more) for early withdrawals. This discourages ending the stake before the lock period expires.

Prerequisites and constraints:

Both contracts must use the same ERC‑20 token.
The ICO flavor must be Caramel and the staking flavor must be UBE.
The ICO must already be created but the presale must not have started yet.

1Confirm the Linking Conditions

You can link a Caramel ICO to an existing UBE staking contract as long as the same ERC‑20 token is used by both contracts, the ICO has been created, and the presale has not started yet.

2Configure Post‑Delivery and Link Staking

Once your Caramel ICO is created, set the Post‑Delivery option to Manual Post Delivery and click Update to approve the transaction. After that, set the Staking Smart Contract (UBE) field to the previously deployed UBE contract address and click its Update button as well.

With these settings, when a user contributes to the ICO and after the ICO has finalized, the purchased tokens will be automatically staked in the UBE contract, behaving exactly like stakes created via the staking UI (see Chapter 5: Staking Solutions).
