What is Vimen?

Permissionless, fully-backed index baskets on Robinhood Chain.

Vimen is the indexing layer of Robinhood Chain (chain id 4663). It lets you own a slice of the market (the Magnificent Seven, the AI buildout, the chain's own native tokens) as one ERC-20 token instead of many.

Each Vimen basket is a mini-ETF built from first principles:

  • A basket token is an ERC-20 fully backed by fixed raw quantities of its constituent tokens, held by its own immutable contract.
  • Mint deposits the constituents in-kind; redeem burns the basket token and returns the constituents in-kind.
  • No oracles in the core. No admin keys over funds. Redeem always works.

The name comes from Latin vimen, the flexible willow twig used for millennia to weave baskets. Each asset is a single twig; woven together they are stronger, and like any hand-woven basket, the weave can always be undone: in-kind redemption is in the name.

Alongside them ships VimenZap, a stateless router that mints or redeems a basket in a single transaction from one asset (native ETH or USDG: an ETH deposit is simply swapped into the constituents inside the same transaction), routing over Uniswap v4 and Rialto. See the zap guide.

Why you can trust it (and where you shouldn't)

Vimen's trust model is deliberately checkable rather than promised:

  • Full backing is a contract invariant. Call isFullyBacked() on any basket, live on Blockscout: the vault holds every constituent 1:1 against supply after any sequence of mints and redeems.
  • Redeem is ungated, forever. No pause, no cap, no guardian power can block a redeem. This is enforced in code and proven by dedicated tests.
  • The admin surface is three functions. The guardian (a Safe) can pause minting, move the supply cap under an immutable ceiling, and change the fee recipient. It cannot withdraw funds, change the recipe, or upgrade anything. Those functions do not exist.

Honesty section

The contracts are unaudited (100% branch coverage, fuzzed, invariant-tested, static-analysis triaged, but unaudited). Deposits are deliberately capped at ≈$100K per basket while the protocol earns trust. The underlying Stock Tokens are debt instruments of Robinhood Assets (Jersey) Ltd and carry issuer risk that Vimen inherits and cannot remove. Read Risks before depositing.
