Extend Supply & Borrow incentives on HUSDT, HUSDC and GIGADOT to 15 January 2027

This proposal extends the Supply & Borrow incentive programmes on HUSDT, HUSDC and GIGADOT by 3 months, from 15 October 2026 to 15 January 2027 (14:00 UTC), and halves the GIGADOT reward rate.

Why

The current programmes were activated in #317 and end on 15 October 2026. HUSDT and HUSDC are the main sources of HOLLAR liquidity outside the Omnipool, so their incentives continue at the current rate. Extending them before the end date means suppliers keep earning without interruption.

As part of an overall reduction in the cost of incentives:

• GIGADOT rewards are halved, from 78.33 to 39.17 GDOT per day.
• HEURC rewards are not extended and end as scheduled on 15 October 2026.

Follow-up referenda will trim the Omnipool farm rates by 10% and top the farms up for the same 3 month period.

What this referendum does

A single batch, executed by the money-market admin account through the EmissionManager:

1. Sets the GIGADOT GDOT emission to 39.17 GDOT per day (half the current rate). Rewards accrued up to enactment are credited at the current rate.
2. Sets the end date of the GIGADOT GDOT programme to 15 January 2027.
3. Sets the end date of the HUSDC PRIME programme to 15 January 2027; the rate is unchanged at 275.6 PRIME per day.
4. Sets the end date of the HUSDT PRIME programme to 15 January 2027; the rate is unchanged at 275.6 PRIME per day.

Cost and funding

The 92-day extension costs 50,713 PRIME (~$54K) for HUSDT and HUSDC (551.2 PRIME per day combined), plus 3,603 GDOT (~$4.8K) for GIGADOT.

No additional funding is required. The PRIME still held in the rewards pot and the Treasury's own unclaimed PRIME rewards (~22,715 PRIME) together cover the extended period. A follow-up referendum on the Treasurer track claims the Treasury's rewards and returns them to the pot. The GDOT extension is covered by GDOT already in the pot.

No other incentive programme, market parameter or user position is affected, and no rewards already earned are changed.

Verification

The full call was executed end-to-end on a fork of mainnet at block 15,706,985. All 4 money-market admin calls dispatched successfully with no EVM failures. Afterwards:

• The HUSDC and HUSDT PRIME programmes end at 15 January 2027 14:00 UTC with unchanged emission.
• The GIGADOT GDOT programme ends at the same time at half its previous emission.
• The HEURC PRIME programme still ends on 15 October 2026.
