# Web3 Engineering

Canonical: https://gaboesquivel.com/web3

I build the product layer around blockchain systems: wallets, signing, exchanges, trading interfaces, auctions, and the data that keeps them in sync.

My focus is where complex protocols become usable products. People need to understand what they own, what happens when they sign, and the state of a transaction—not the complexity of the infrastructure behind it. My earlier work in financial products, including Wink, still shapes how I approach identity, security, and moving money.

## ZTX

At ZTX, I built wallet connectivity inside a WebGL virtual world. Using MetaMask, Ethers.js, and a custom JavaScript event system, I connected the experience to EVM transactions so users could sign and trade NFTs without leaving the world.

## Trading and financial products

From browser-based signing to onchain trading, these products required complex transactions to feel clear, responsive, and trustworthy.

### Bitcash

I worked on peer-to-peer exchange flows, WebAuthn key management, and QR-based transaction signing directly in the browser.

### Bitlauncher

I built token auction interfaces, wallet interactions, and transaction data integration across EOS EVM and EOS, including Gnosis auction contracts.

### Opyn

I built the trading interface for a perpetuals protocol on Arbitrum, integrating wallet actions and indexed onchain market data.

### RareMint

I integrated WalletConnect into a Polygon collectibles marketplace, enabling participation in auctions and NFT transactions.

## Protocols and infrastructure

My earlier blockchain work was closer to the underlying networks and applications. It gave me a deeper understanding of the systems that later informed my work on wallets, markets, and onchain interfaces.

- [Knowledge](https://gaboesquivel.com/project/knowledge-io): ERC-20 contracts, serverless AWS services, and a React/Web3.js marketplace with a wallet dashboard.

- [EOS Costa Rica](https://gaboesquivel.com/project/eos-costa-rica): EOS mainnet infrastructure, validators, and a private EOSIO network for enterprise transaction workflows.

- [ChainGraph](https://gaboesquivel.com/project/chaingraph): An open-source GraphQL toolkit for querying and streaming EOSIO and Antelope blockchain data.
