Developing. Some claims here are not yet confirmed; they are listed apart from the confirmed facts. A new version replaces this one when the primary evidence changes.

## What happened

Arbitrum DAO opened a constitutional Snapshot proposal to register custom USDS and sUSDS gateways in the canonical router used by the official bridge UI.

## What changed

A concrete governance path opened for routing two Sky assets through token-specific custom gateways instead of default gateway handling in the official UI.

## What did not change

The March proposal did not change router state or authorize execution. The custom bridge contracts were already live, while official UI routing remained disabled pending governance.

## Confirmed

- The proposal identified the Ethereum and Arbitrum custom gateway contracts and USDS and sUSDS token addresses.
- The proposal stated that the router configuration still used default gateways and that official bridge UI access was disabled for these tokens.
- The March Snapshot record opened a governance vote before later execution stages.

## Still open

- Governance approval, payload verification, and execution were not completed during March.
- Independent verification of the final governance payload and router state remained outstanding.
- Registration would not itself establish the suitability or solvency of USDS or sUSDS.

## What it means for an advisor

- Track the proposal because it would add a token-specific custody and upgrade path to the official Arbitrum bridge interface.
- Keep Sky-asset diligence separate from the Arbitrum bridge memo; router registration does not approve either asset.
- Require executed router state and verified gateway controls before treating the UI path as operative.
