From Mar. 12, 2025 to Mar. 21, 2025, Lombard engaged Veridise to conduct a security assessment of their LBTC Solana Program. Previously, Veridise audited the EVM (Solidity) version of the LBTC contract. This engagement focused on reviewing its Solana counterpart. While the Solana implementation preserves the intended functionality of the EVM version, it has been restructured to align with Solana’s distinct development model and constraints.

Following the initial review, the developers requested an additional assessment of the newly completed Bascule feature. This supplementary review was conducted from Mar. 26, 2025 to Mar. 27, 2025.

Veridise conducted the assessment over 4 person-weeks, with 2 security analysts reviewing the project over 2 weeks. The review strategy involved a tool-assisted analysis of the program source code as well as thorough code review performed by Veridise security analysts.
