Move permissioned assets,
keep the permissions.
Escrow an ERC-3643 asset on Ethereum, mint a permissioned twin on Starknet. Eligibility travels with the tokens — and expires if it goes stale.
Compliance crosses too
The twin runs the full ERC-3643 gate against a mirror of the source registry, not a copy made once at launch.
Fails closed
If the mirror goes stale, transfers stop until someone refreshes it. Anyone can — it only forwards what the source already says.
Nothing is stranded
A transfer that arrives for an ineligible holder is quarantined and claimable later, never rejected back into the void.
