Live on Robinhood Chain Testnet
One Account.
Full-Book Control.
Crypto markets move together. Your margin should too. MetaMargin reads every asset in your wallet as one book, then shocks it before the market does.

Hit the book before the market does
A single-trade view hides the real damage. When ETH drops, it drags the account standing behind everything else. Load a cartridge with keys 1 to 5, or drag any position, and read the whole book at once.
How a reading is made
wallet → core → prices → lens → you
- 01
Wallet
Connect any EVM wallet. Reading your book needs no signature and no approval.
- 02
CORE
MetaMarginCore.book() returns every listed balance at one block, in one call.
- 03
Prices
Coinbase for crypto, Nasdaq and NYSE for stocks, refreshed server-side every 30 seconds.
- 04
LENS + RADAR
MetaMarginLens runs the shocks and the concentration math in fixed-point integers.
- 05
You
The book, the hit and the rank on one screen. Your keys stay in your wallet the whole time.
The terminal
Six instruments, one keyboard
Every instrument has a key. Press it and you are there. CORE reads the book, LENS hits it, RADAR grades it, and the rest keep you close to the market.
CORE
Every listed asset your wallet holds, read in a single call and stamped with the block it came from. The foundation every other instrument stands on.
MetaMarginCore.book(address)
1 eth_call · registry order · block-stamped
LENS
Load a scenario cartridge or drag one position. Watch the whole book answer, then re-run the math on chain.
MetaMarginLens.shock(values, bps)
RADAR
Concentration, class mix and standard stress loss, graded S to D with readouts in plain English.
MetaMarginLens.read(tokens, values)
Markets
Crypto majors next to the stocks behind Robinhood Chain's tokens, with live charts and 24h stats.

Contracts · Robinhood Chain Testnet
Every contract, verified and on chain
Each module is a UUPS implementation behind its own ERC-1967 MetaMarginProxy. The addresses below never change across upgrades, and the source of every one is published on the explorer.
Registry
MetaMarginRegistry
Curated assets and markets, risk parameters and the official $METAMAR address
assets() · markets() · token()
CORE
MetaMarginCore
Portfolio engine that reads every listed asset a wallet holds in one call
book(address)
LENS · RADAR
MetaMarginLens
Fixed-point risk math for scenario shocks, concentration and stress exposure
simulate() · read() · shock()
Upgrade path
Ownable2Step guards every upgrade. Implementations lock their initializers in the constructor, and storage layouts are checked by the OpenZeppelin upgrades plugin before anything ships.

Token
$METAMAR
$METAMAR launches independently on Robinhood Chain. Its address is written to MetaMarginRegistry the moment it goes live, so the only CA that counts is the one the contract says. Copy it from here or read it yourself on the explorer.
