The signers are part of the SwissBorg ecosystem. \- **`manager`**: **which can pause the bridging.** The manager will be a 3-out-of-5 multisig. The signers are also part of the SwissBorg ecosystem. ### WormholeTransceiver.sol The transceiver can be upgraded and has three roles defined: \- **`owner`**: **which can upgrade the contract and perform administrative actions (like setting relayers).** The owner will be a 5-out-of-7 multisig. The signers are part of the SwissBorg ecosystem. \- **`manager`**: **which can pause the bridging.** The manager will be a 3-out-of-5 multisig. The signers are also part of the SwissBorg ecosystem. \- **`relayer`**: **which can unlock some tokens.** The relayer is the Wormhole bridge. The addresses of all contracts, including the multisigs are on this page: {% content-ref url="/pages/yPbPqMHXc3i37rcJmeV3" %} [Contract Addresses](/bridge/contract-addresses.md) {% endcontent-ref %} --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.swissborg.com/bridge/security.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
