Rudransh Singh Tomar

Protocol Engineer and Backend Developer specializing in scalable Web3 architecture, quoting infrastructure, and backend pipelines across EVM, Solana, NEAR, and ICP.

• Ladder (Protocol Engineer): Architected core tranching protocols, executing 5 ERC-4626 vault integrations and Monte Carlo simulations modeling CSMM behavior. Built 3 mainnet DeFi integrations (Solidity 0.8.20), successfully clearing external audits.

• Prospective LLC (Smart Contract Auditor & Backend Engineer): Secured mainnet launches on Tron, EVM, Polygon, BSC, and Solana. Built a multichain SubSquid indexer, a custom Tron block poller, and an EIP-712 server flow. Reported 25 audit findings using Slither, Mythril, Echidna, and Halmos.

• NEAR Intents AMM Solver: Built a production AMM solver (TypeScript/Rust) quoting swap intents and settling on NEAR mainnet. Secured the signer in a Phala TEE with replay guards for partial fills.

• StableSwap Pricing & Arbitrage Engine: Wrote a Python pool state engine pricing swaps with zero quote-path RPC calls, cross-validated against Solidity via Foundry fuzz tests.

• TickStream Market Data Pipeline: Engineered an async Kafka/Redis ingest service aggregating exchange WebSockets into 1-minute candles, featuring idempotent UUID upserts and a dead letter queue.

• Rheolly Cross-Chain Execution Service: Routed positions across Ethereum, Base, and Arbitrum under ERC-7579 session keys. Indexed Aave V3/ERC-4626 events via SQD archive gateway for APY computation.

• Trust Protocol (Co-Founder & Lead Developer): Designed an under-collateralized lending mechanism. Deployed UUPS proxies on Base, ported to Sui Move, and served 100+ beta users.

• KaiFoundry (Lead Developer): Built a multi-token CPAMM on ICP (Rust) and designed EVM migration contracts for KILT. Scaled Motoko stable memory from 4GB to 400GB and reduced user fees by 40%.

• Early ICP & Hackathons: Built an NFT POS gateway and the ICP global merch store. Won a $25k grant at the Encode x ICP hackathon for Hush Protocol, an on-chain wallet recovery system using VetKeys BLS encryption.
