softstack has concluded an external security audit of Lambdaplex’s core smart contracts. The review uncovered 34 findings: none at the critical severity, 2 high, 11 medium, and 13 low
FLENSBURG, GERMANY, August 16, 2026 /EINPresswire.com/ — softstack has finished an independent security assessment of Lambdaplex’s fundamental contracts. The analysis covered four elements of the Hedera-based protocol: the balanced vault, the order hook, the settlement layer, and the pro rata vault.
The softstack audit team performed a manual code review alongside automated security testing. The assessment identified 34 issues: zero critical, two high, eleven medium, thirteen low, and eight informational. Both high-severity vulnerabilities were remediated. In total, 22 issues were addressed and 12 were formally acknowledged, with no unresolved items remaining at the conclusion of the engagement. A subsequent verification confirmed that the fixes were implemented as designed.
The review examined share-accounting correctness, oracle price validation, signed-order authorization and replay protection, manager-rebalancing boundaries, access control, and reentrancy safeguards. The engagement started with an initial audit early in 2026 and was later broadened to include the settlement layer and the pro rata vault, ending with a final re-check in August.
About Lambdaplex
Lambdaplex is a Hedera-native, non-custodial on-chain trading protocol. It places limit, market, stop-loss, and take-profit order logic at the account level via Hiero Hooks and the Hedera Token Service, so custody remains with the user while brokers, solvers, or matching engines are able to execute open orders. The hook independently validates each transfer against the user’s price limits, slippage bounds, and oracle-based triggers.
Alongside the order hook, Lambdaplex runs a settlement layer for final on-chain trade execution, a balanced vault with an oracle-driven inventory policy, and a pro rata vault whose shares represent a proportional claim on live two-asset inventory without an external price feed. The protocol is designed for professional and institutional trading use cases that require deterministic execution and strong self-custody.
