Found 1 High severity bug in a cross-chain TITN token contract. A `to != lzEndpoint` exemption in the transfer-lock check created an escape hatch — restricted holders could route tokens through the LayerZero endpoint and bypass the lock entirely. First contest, first finding.

Found 2 High severity bugs in a 128-bit floating-point Solidity library. Key finding: ln(0) did not revert, silently returning an invalid result, violating mathematical invariants and exposing dependent protocols (AMMs, lending rates) to silent precision errors.

Found 1 Medium severity bug in the FERC20 token contract. `burnFrom()` reduced user balances without decrementing `_totalSupply`, permanently inflating the reported circulating supply and breaking the core ERC20 accounting invariant.
