Connect every venue, watch positions move in real time, and keep the data on infrastructure you actually control. No tracking pixels, no SaaS lock-in.
Live price feeds and valuations streamed in — no polling, no stale numbers. Every position updates the instant a trade settles.
API keys live behind AES-256-GCM authenticated encryption with per-user key derivation. Nothing readable on disk, ever.
Exchanges, wallets, and cold storage merged into a single position table. One source of truth across every venue.
One binary. One config. Run it on a Pi at home or a VPS at the edge. Your data never crosses a network you don't own.
Per-position cost basis, realized vs unrealized P&L, time-weighted return. The math you'd actually use to make decisions — not vanity metrics.
Revolut X is live today. Major centralized exchanges and self-custody wallets are landing through this quarter.
OAuth-based read access to balances and order history. Two-way sync ready.
Spot, margin and earn balances. Read-only API keys with IP allow-listing.
Advanced Trade API. Portfolio, transactions, and staking positions.
Spot, futures, and staking. WebSocket feed for tick-level updates.
Read xPubs over the Ledger Live API for read-only cold-wallet tracking.
xPub import flow for Bitcoin, Ethereum and ERC-20s. No seed exposure.
Watch any wallet address across Ethereum, Polygon, Base, and Arbitrum.
For everything we don't speak yet. Map columns once, re-use the profile.
Nucleus is built so the people who write it can't read what you store in it.
A short, opinionated list. We'd rather finish four things than start ten.
OAuth flow, holdings sync, transaction history. Available today on the main branch.
Spot, earn, and staking balances. Optional IP allow-list per credential.
Ledger, Trezor, and arbitrary xPubs. Bitcoin first, EVM chains next.
FIFO / LIFO / HIFO. Per-jurisdiction CSV exports for end-of-year filing.
A small read-only companion app for checking positions on the train.
One binary. One config. Five minutes from clone to first sync. Your data stays on your machine.
