Lambdaplex completes security audit of Hedera core contracts

softstack completed an independent review of Lambdaplex’s Hedera core contracts ahead of mainnet, covering the Vault, Orders and Settlement layers. The audit found 22 issues, all of which were addressed as Lambdaplex prepares a non-custodial trading protocol for launch. Why it matters: - The audit is a key pre-mainnet check for Lambdaplex’s non-custodial trading protocol on Hedera. - Security review focused on the contract logic that handles user custody, order execution and settlement. - The work is aimed at reducing operational and smart contract risk before launch. What happened: - softstack completed an independent security assessment of the Lambdaplex Core Contracts. - The review covered three contract suites: the Vault, the Orders and the Settlement layer. - The audit examined signed-order authorization, share accounting, inventory rebalancing, oracle proof verification with Supra, IOC/FOK execution semantics in the Order Hook and atomic settlement through the Hedera Token Service via cryptoTransfer. - The engagement identified 22 issues. - Lambdaplex and softstack addressed all findings during the review. The details: - The assessment combined manual expert review with automated security testing. - Every contract in scope was checked against Lambdaplex security claims. - The review included reentrancy protection, access control, replay protection and oracle integrity. - Lambdaplex says the protocol enables high-performance, non-custodial spot trading with advanced order functionality at the account level. - Lambdaplex embeds trading intent and execution rules into user accounts rather than centralized smart contracts. - Limit, market, stop-loss and take-profit orders are expressed as deterministic constraints enforced by the hook. - Custody remains with the user. - The settlement layer finalizes trades atomically through HTS, with replay protection on signed orders and settlement hashes. - Lambdaplex described the audit as helping harden the Core Contracts before mainnet. - softstack CEO Yannik Heinze said the team implemented every actionable fix quickly. Between the lines: - The audit suggests Lambdaplex is prioritizing security architecture before trying to scale trading activity. - A multi-layer review is especially important for a protocol that combines account-level execution rules, oracle data and atomic settlement. - The fact that all findings were addressed lowers, but does not eliminate, the risk of launch-time contract issues. What’s next: - Lambdaplex is preparing to go to mainnet. - The company says the audit gave it the assurance needed to go to market. - More information is available on Lambdaplex’s website. The bottom line: - Lambdaplex has cleared a major security milestone ahead of launch, with softstack’s review covering the protocol’s core trading, oracle and settlement contracts.
