Thoughts on DeFi & TradFi engineering, distributed systems, and market structures. Welcome to my digital timed garden 🌿
Inside the architecture of the first white-label stablecoin platform from M0, PayPal, and MoonPay — the PYUSDx base token and its per-earner reward accounting, MultiMint extensions and the Swap Facility, the solver-driven liquidity layer, and versioned beacon upgrades.

A newspaper-style review of twelve months of stablecoin extensions built on M0 — twenty digital dollars across eighteen chains, from MetaMask's wallet dollar to MoneyGram's remittance rail. TVL analytics, per-partner reporting, and money-flow diagrams, with supply figures read live from the M0 protocol API.

Change is the only constant, and the most adaptable survive and thrive. A review of Uniswap's shift toward an institutional future and the RWA space in three major 2026 projects — BUIDL swaps via UniswapX, the DualPool hook with Spark, and Permissioned Pools — and how they actually work.

Two years in, M0 has processed over $1.1B in mints, expanded to Solana and 15+ EVM chains, and become the first white-labeled stablecoin platform. With JMI and new liquidity offerings on the horizon, going back to basics: how and why things were built the way they were.

Simple is way more than simplistic. The story of the algorithm behind staking rewards contracts everywhere — from the 2018 Scalable Reward Distribution whitepaper and SNX's Unipool to Uniswap v3 fee tracking, SushiSwap's MasterChef, and 1inch's ERC20Plugins.

How the M0 Protocol tracks interest accrual on stablecoin issuance through two fundamental concepts: principal amounts and a global interest rate index. A shared index eliminates gas-intensive calculations across all protocol participants while maintaining precise balance tracking.

Co-developed the backend for MoonPay’s self-custodial wallet powering its NFT marketplace.
Implemented BTC-to-ETH atomic swaps for the Bosonic Network, a cross-custodian settlement platform for real-time netting, clearing, and atomic payment-versus-payment settlement that removes counterparty credit and settlement risk.
Implemented core components of Sourcegraph’s code analysis engine, which powered cross-repository go-to-definition, find-references, and semantic code navigation.
Delivered the first implementation of COBOL modernization software for major US logistics and financial infrastructure providers. Formed and led a team of up to 6 engineers.
Contributed to telecom and banking projects after completing a software architecture and system design training program.
First job, combined with university studies. Programmed compilers in functional languages such as Lisp and Haskell.

Hi, my name is An-toni-na and I'm from Kyiv, Ukraine ♥♥. I've spent the last eight years in the US, splitting time between SF and NYC. I love both, but undeniably, I vibe better with the latter.
After moving to the US, I got into blockchain engineering and later found myself in DeFi — finally loving what I do and connecting the dots of my past: a math & physics lyceum, an applied math master's, and systems programming at an undisclosed R&D lab.
When I'm not working or chasing kids around (which is almost never), I like to get out and explore the countless beautiful places in and around NYC.
