Introduction

I'm Filipe Venancio. I write smart contracts and build DeFi protocols. Been shipping code since 2008, got into crypto in 2020, and haven't really looked back.

Currently a Techlead at Keyrock, where I work on asset management infra, account abstraction, and cross-chain systems. Before that, I was CTO at Veris Labs building lending protocols and yield vaults.

I care about code that works, systems that don't lose people's money, and keeping things simple. I am open to new opportunities.

Experience

Techlead @ Keyrock 2025 — Present

End-to-end architect of the KAM protocol. Designed the full system (smart contracts, frontend, backend), selected the tech stack, and managed a cross-functional team to build an institutional asset management ecosystem.

CTO @ Veris Labs 2023 — 2025

Architected the full web3 translation for Unlockd (RWA lending) and maxAPY (yield optimizer) to $1M+ TVL. Directed a 7-person engineering team across all stack layers and authored the core smart contracts.

Tech Lead @ Themar Solutions 2022 — 2023

Led deep technical R&D for complex protocol integrations and hands-on smart contract development.

KAM Protocol (Keyrock)

What I'm building at Keyrock — asset management with smart accounts and cross-chain tokens.

KAM / kToken0 [LIVE TESTING] 2026

Custom VaultsBatchingLayerZeroOFT

Custom batched vault with OFT tokens bridging via LayerZero. Built a proprietary batching system to heavily optimize gas for requests and claims.

KAM Core · kToken0

View Architecture & Details

The Genesis: kToken0 is a protocol-specific stablecoin for KAM. The kMinter contract handles minting and burning, creating a 1:1 mapped kToken for every accepted asset (e.g., kBTC, kUSDC).

Architecture & Approach: Instead of relying on standards like ERC-7540, we built our own proprietary vault architecture using a highly optimized batching system. This saves users massive amounts of gas by optimizing deposit requests and claims. For bridging, I chose LayerZero (OFT v2) over CCIP because of the flexibility it offered; we controlled the DVNs entirely, guaranteeing no possibility of hacking the messaging system.

Tech Stack: Solidity, TypeScript (Fullstack), Foundry, Soldeer, Vercel, Cloudflare, Fordefi (Wallets), Elliptic (KYC), Blockaid (Monitoring).

The Outcome: Delivered a highly secure, frictionless cross-chain stablecoin minting vault alongside automated strategy vaults.

Smart Account Infrastructure [LIVE TESTING] 2026

ERC4337ERC1967Account Abstraction

A gas-efficient smart account and factory system. Keeps logic minimal and highly auditable.

Minimal Smart Account · UUPS Factory

View Architecture & Details

The Genesis: Standard wallets were too rigid, and existing factory patterns often contained admin backdoors. We needed a highly efficient, minimal smart wallet infrastructure that could be deployed identically across all chains using CREATE2.

Architecture & Approach: I built `minimal-smart-account` with batch execution and registry-based authorization. I paired it with `minimal-uups-factory`, a factory that deploys ERC-1967 proxies and completely removes itself from the picture afterward, ensuring upgrades only happen via the proxy itself.

Tech Stack: Solidity, Assembly (Solady), Foundry, Soldeer.

The Outcome: A trust-minimized, multi-chain-ready smart account foundation devoid of admin backdoors, delivering massive gas savings and operational security for the protocol.

KAM Ecosystem [LIVE TESTING] Q1 2026

SettlerPaymasterWallet

Settlement engine, gas paymaster, and the wallet that ties it all together.

kam-settler · kam-paymaster · metawallet

View Architecture & Details

The Genesis: The vision was to push everything possible on-chain, drastically simplifying the frontend and backend to deliver the absolute best UX.

Architecture & Approach: A sophisticated trinity. The Paymaster lets users pay gas directly in vault tokens. The Settler handles vault settlements using hardcoded math to ensure absolute security—even a compromised backend can't manipulate values (protected by delta-checks requiring extra signatures). The Wallets handle strategy funds and CEFFU transfers, functioning as ERC-4626s themselves so shares can be transferred natively between vaults without gas-heavy deposit/withdrawals.

Tech Stack: Solidity, TypeScript (Fullstack), Foundry, Soldeer, Vercel, Cloudflare, Fordefi (Wallets), Elliptic (KYC), Blockaid (Monitoring).

The Outcome: A bulletproof, gas-abstracted ecosystem. We steered the codebase through an initial audit with Ginger Security, followed by a rigorous secondary audit with Trail of Bits, and it is now under live testing.

DeFi History

MetaVault [SUNSETTING] 2025

SuperformLI.FICross-chain

The first fully on-chain strategies vault. Pulls yield from strategies across 9 chains.

GitHub

View Architecture & Details

The Genesis: We aimed to build the first fully on-chain strategies vault to generate maximum yield, achieving a verifiable and stable 1% yield PER MONTH on the USDC vault.

Architecture & Approach: We leveraged Superform to deploy funds across strategies, and LI.FI so users could deposit any token from any chain. We built a custom hurdle rate oracle to ensure we only charged fees if our vault's rate beat T-Bills (for USDC) or Lido (for ETH). For valuation, we built a proprietary share-price-oracle that uses LayerZero to bridge exact share and asset prices from strategy chains back to Base. The MetaVault queries this to safely calculate its own share price, with strict invariants (like never returning 0) to prevent manipulation.

Tech Stack: Solidity, TypeScript (Fullstack), Foundry, Soldeer, Cloudflare (Backend), Vercel, Safe Wallets.

The Outcome: A brilliant UX where a specialized strategy index controlled cross-chain flows. The massive success of this protocol directly led to Veris Labs being acquired by Keyrock, where our core team transitioned to build the KAM Protocol.

maxAPY v2 [SUNSETTED] 2024

DeFiYield

Yield aggregator. Routes deposits across major DeFi protocols to chase the best rates.

App

View Architecture & Details

The Genesis: We wanted to tap into the deepest liquidity and highest yields in DeFi by deploying capital across the biggest protocols (Curve, Uniswap, Convex, Yearn).

Architecture & Approach: We built 4 specialized vaults (2 for Polygon, 2 for Mainnet supporting ETH and USDC). For each chain, we built complex custom integrations to route money into diverse strategies.

Tech Stack: Solidity, TypeScript (Fullstack), React, Google Serverless, Foundry, Vercel, Safe Wallets.

The Outcome: maxAPY v2 served as the architectural proving ground that eventually evolved into the cross-chain perfection of MetaVault.

Unlockd v2 [SUNSETTED] 2023

RWASafe

Borrow against RWAs and NFTs via Safe wallets, retaining asset utility.

Website

View Architecture & Details

The Genesis: Users wanted to borrow against RWAs (real estate, gaming assets, stocks, watches) without giving up the utility of those assets. We originally started building this while at Themar Solutions, but the core engineering team transitioned directly to the client (Veris Labs) to see it through to completion.

Architecture & Approach: Users deploy a Safe wallet with us as a co-signer. Our signature acts as a lock/unlock mechanism for the NFTs. The lock prevents transferring the NFT out, but users can still use the wallet to prove ownership, claim airdrops, and vote in governance.

Tech Stack: Solidity, TypeScript (Fullstack), React, AWS Kubernetes, Terraform, Foundry, Vercel, Safe Wallets.

The Outcome: A beautiful, trust-minimized lending protocol. If a user defaults, we initiate an auction or use Reservoir integrations to liquidate the asset, all while the user retains full utility of their collateral until the last moment.
