# Security Audits As with all crypto technology, risk is real whether using a centralized or decentralized bridge. Some of the more novel decentralized bridges are relatively untested and even those that have been tested are still subject to exploits. Brotocol is audited by [CoinFabrik](https://www.coinfabrik.com/) and [Defence](https://thesis.co/defense), covering both the contracts and the backends. * [2022-12 Bridge Endpoints](https://cdn.xlink.network/pdf/ALEX_Audit_bridge_coinfabrik_202212.pdf) * [2023-04 Bridge Backend and Endpoints](https://cdn.xlink.network/pdf/ALEX_Audit_Bridge_2023-04.pdf) * [2023-10 Bitcoin Oracle and Bridge](https://cdn.xlink.network/pdf/ALEX_Audit_202310_Bitcoin_Oracle_and_Bridge.pdf) * [2024-06 BridgeEndpoint, BridgeRegistry and BridgeEndpointWithAxelar](https://cdn.xlink.network/pdf/XLink_Bridge_Endpoint_Audit_2024-06.pdf) * [2024-06 MultisigWallet and BridgeToken](https://cdn.xlink.network/pdf/XLink_MultisigWallet_BridgeToken_2024-06.pdf) * [2024-11 Brotocol Staking Manager](https://cdn.xlink.network/pdf/XLINK_Staking_Audit_2024_11_final.pdf) * [2024-11 Brotocol Peg-out Endpoints](https://cdn.xlink.network/pdf/XLINK_Peg-out_Endpoints_Audit%2011-2024.pdf) * [2024-11 Brotocol Peg-in Endpoints](https://cdn.xlink.network/pdf/XLINK_Peg-in_Endpoints_Audit_11-2024.pdf) * [2025-03 Endpoint Update](https://cdn.brotocol.xyz/pdf/XLink_Endpoits_Update_Audit_2025-03.pdf) * [2025-04 EVM Endpoints](https://cdn.brotocol.xyz/pdf/XLink_EVM_Endpoint_Audit_2025-04.pdf) * [2025-05 Solana Endpoints](https://cdn.brotocol.xyz/pdf/XLINK_Solana_Endpoint_Audit_2025-05.pdf) * [2025-08 EVM BridgeEndpoint](https://cdn.brotocol.xyz/pdf/250825_Defense_by_Thesis_Brotocol_BridgeEndPoint_Smart_Contract.pdf) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
