LayerZero contributed the following description of OFTAdapter Burn:

Introduce a custom OFT adapter contract that integrates a new IMintSelfBurnToken interface to burn ERC20 tokens when debiting from the source chain and mint the same amount when crediting on the destination chain. This shifts the bridging mechanism from “lock-and-unlock” to burn-and-mint, ensuring a single global supply of ERC20 tokens across chains while preserving OFT semantics.

Zellic conducted a security assessment for LayerZero from June 3rd to June 4th, 2025. During this engagement, Zellic reviewed OFTAdapter Burn's code for security vulnerabilities, design issues, and general weaknesses in security posture.
