Santiago Chopitea

Software engineer · web3 and frontend · Buenos Aires, Argentina

TypeScript JavaScript React Next.js Node.js Solidity Hardhat Ethereum Neovim


I contribute to wallets and dapps, frontend and backend. My work sits at the integration layer, where smart contracts meet the interfaces and services people actually use.

Selected work

Implemented the Privacy Pools SDK in Kohaku Wallet, a fork of Ambire Wallet built at Wonderland — a proof of concept for private, compliant transactions.

ethereum/kohaku-commons
ethereum/kohaku-extension

Co-author of two Ethereum Foundation proposals for interoperable, chain-specific addressing — part of the broader push toward private cross-chain payments.

ERC-7930: Interoperable Addresses
ERC-7828: Interoperable Names

Two accounts, one person

My professional history from 2024 onwards also lives on @Onizuka-wl. GitHub cannot merge accounts, so both stay cross-linked on purpose.
