About

I'm Tsolmondorj Natsagdorj, an engineer working where cross-chain infrastructure, smart-contract security, and AI agents meet. I build bridges, audit them, and write the agents that trade across them.

Now

I run Zero 1 Labs, a personal holding company for my ventures and research. Its flagship is Suwappu — an agent-native cross-chain DEX with a post-quantum bridge I designed and audited end-to-end. The custody layer is gated by on-chain attestations (ML-DSA-65 on the home chain); I proved the supply and double-spend invariants with Foundry stateful fuzzing, Slither and Halmos, and shipped every fix with a revert-fails regression so the test goes red again if the fix is removed.

Open source

• alloy-rs/coremerged — EIP-712 self-referential struct canonicalization in dyn-abi. alloy underpins Foundry and Reth.
• uutils/coreutilsmerged — date timezone handling in the Rust rewrite of GNU coreutils.
• Open contributions to HuggingFace candle (a causal-mask prefill fix), polars (non-UTF8 CSV encoding), and Apple's mlx-lm.

Before

I co-founded Blockchain at Mason (2016–2017), a student-run, faculty-supported organization I grew to 90+ members; we helped launch one of the first university blockchain minor programs in the US. I studied Economics & Computer Science at George Mason University, leaving in 2017 to work on this full-time.
