# Sky proposes Configurator controls for Spark’s Arbitrum allocation system

> The proposed authorization enables bounded rate-limit changes and a preconfigured emergency CCTP-facet removal without a new spell. Beacon administration is to move from Spark’s executor to the core governance relay.

- Type: Control change
- Stage: Proposed
- Evidence: confirmed
- Materiality: material
- Event date: 2026-10-03

- Affects: Sky (protocol); Spark Liquidity Layer (protocol)

## What happened

Sidestream published the technical scope for attaching predeployed PAS and Configurator contracts to Spark’s Arbitrum Diamond PAU.

## What changed

The proposed authorization enables bounded rate-limit changes and a preconfigured emergency CCTP-facet removal without a new spell. Beacon administration is to move from Spark’s executor to the core governance relay.

## What did not change

Deployment alone does not establish PAU authorization or live allocation operations. The initially paused Timelock prevents delayed operations until a future core spell unpauses it.

## Confirmed

- The scope identifies Configurator 0xd11Dc57F3eF23bb7b3142588a461F68460a7C474.
- The new controller and legacy controller are intended to share the existing Arbitrum ALMProxy.
- The documented growth settings are a 16-hour interval and 1.20 multiplier, subject to required confirmations.
- The scope explicitly requires Configurator authorization on the new PAU’s access controls and rate limits.
- The documented Beacon still requires admin handoff to L2GovernanceRelay.

## Still open

- Risk-parameter and operator-address confirmations.
- Final deployment validation and parallel-controller review.
- Spark Arbitrum spell execution, Configurator authorization and Beacon admin handoff.
- Actual rate-limit values and functioning emergency removal after activation.

## What it means for an advisor

- Review Sky and Spark authority maps for shared custody, local operator powers and emergency facet removal.
- Verify paused-Timelock restrictions before treating the nominal 14-day delay as an active protection.
- Require executed authorization and final deployment review before recording these controls as operative.
