Rudransh Singh Tomar

Conducted pre-audit reviews for ERC-404, TRC-404, and Polygon smart contracts in a 34-week$8,000 engagement, identifying and resolving critical vulnerabilities to minimize external audit costs and ensure secure mainnet deployment. Employed 2025 best practices as senior auditor, leveraging Slither, Mythril, Echidna, MythX, and Halmos for static and symbolic analysis, fuzzing, and formal verification.

Conducted manual reviews to detect reentrancy, oracle manipulation, front-running, unchecked calls, and logic flaws in cross-chain contracts.

Architected 3 production ready DeFi protocol integrations ( ̃5,000+ lines of Solidity 0.8.20) featuring ERC-4626 vault wrappers, multi-asset AMM pools, and async state management. Developed a dual-path asset routing system utilizingUniswap V3andChainlinkoracles (Falcon Finance), and an escrow-based request queue for async epoch-based redemptions (Upshift Finance).

Engineered a multi-asset CSMM pool usingStableSwap invariant mathfor low-slippage swaps between tranche tokens and USDC, incorporating custom oracle rate-adjusted pricing. Ensured protocol security via strict CEI patterns and achieved 100% pass rate across 1,500+ lines ofFoundryunit/fork tests, optimizing gas via batch execution.

Co-founded and developed an extensible trust layer for undercollateralized loans, utilizing novel game theory to replicate off-chain trust on-chain usingSolidity. IntegratedENS/Gitcoin Passportfor Sybil resistance andAAVEfor yield generation, boosting user retention by 45% among 100+ active beta members.

Implemented CI/CD pipelines viaGitHub Actions, reducing deployment time by 70% and automating multi-chain testing.

Implemented on-chainDAOs,NFTs, andDeFiapps reducing fees by 40% viaICPoptimization. Designed Stable memory implementation inMotokoto increase storage from 4 GB to 400 GB. Architected anorderbook based perpetual exchangewhich allows users to hold assets in desired chain using Near Intent’sChain Abstractionand then trade and settle onAlgorand.
