Contract Ownership

The initial deployment chains use "Nested" Safe configurations as contract owners, while extension chains are managed through Abacus Works Safes.

The Safe structure enables:

• Enhanced security through multiple signature requirements

• Shared ownership

• Transparent and auditable on-chain operations

The table below provides links to both Nested and AW Safes on each of the oUSDT chains, and indicates which Safe is used.
