Multi-chain portfolio

Any wallet's priced holdings — native coins and ERC-20s — across Ethereum, Base, Arbitrum, Optimism, and Polygon, with a total and a per-chain breakdown.

Norien's native data is Robinhood Chain. The portfolio widens that: paste any address and get its full picture across the major EVM chains in one view — net worth, what it holds on each chain, native balances, and every priced token. Spam and sub-cent dust are filtered out automatically.

In the app

Open Portfolio in the sidebar, paste a 0x… address, and hit View portfolio. You get:

Net worth — the total USD value across all five chains.
By chain — a bar breakdown of value per chain.
Native balances — ETH / POL held on each chain, priced.
Tokens — every priced ERC-20, with balance, price, and value.

Note —A direct link works too: https://app.norien.live/portfolio/0x… jumps straight to an address.

From the API

One public, unauthenticated endpoint. Every value is USD; the response carries its usual sources / degraded envelope.

Chains covered

Ethereum, Base, Arbitrum, Optimism, and Polygon. Only positions with a real USD price are shown, so the list stays meaningful rather than flooded with airdrop spam.

Careful —A wallet with thousands of tokens may not show every ERC-20 — the priced, non-dust holdings come first. Native balances and the total are always complete.
