03Gravity flow

Liquidity has a destination.

Capital enters on Ethereum, is locked, verified, and lands on Robinhood Chain as a GravFi representation. The diagram is a walkthrough of the mechanism, not a live transaction.
  1. 1
    Ethereum
    Source asset leaves the user's wallet.
  2. 2
    GravFi Vault
    Collateral locked in a single-asset vault.
  3. 3
    Verification
    The messenger delivers the lock proof; the bridge checks eid, nonce and route.
  4. 4
    Robinhood Chain
    The gToken is minted to the recipient, 1:1 with the vault.
  5. 5
    DeFi Liquidity
    The representation trades, pools, and routes on Robinhood Chain.

Real wraps happen in the application, produce on-chain events, and are tracked by contract state — see /app/bridge.

04Proof of Gravity

Every unit should have a home.

Each gToken is compared against the collateral its vault actually holds, read from both chains at a pinned block. When contracts are not deployed, that is what you see.

05Supported assets

Pull assets in.

Stablecoins, bitcoin and gold with canonical Ethereum contracts. A gToken appears only when its vault and token are deployed; nothing is listed as live before that.

06Gravity Router

Route capital.

Pick a source asset and a target gToken; the router quotes the bridge leg and the swap leg from live contracts. It never claims atomicity: two chains means two transactions, and it shows both.

07Liquidity

Backed on-chain.

Pools are enumerated from the configured router's factory and read at one block. USD TVL and volume are shown only when a price source exists — today it does not, so they are omitted.
08Integrators

Verify, don't assume.

Everything the interface knows is readable by anyone: asset registry, contract addresses, ABIs, and a reserve engine you can run yourself.

09Security

Contract architecture.

Role separation, pause switches, rate limits and reentrancy protection across four small contracts. The bridge does not invent a messaging protocol; it plugs into one.
GravVault
  • Single-asset custody
  • BRIDGE_ROLE-only deposit and withdraw
  • Rolling withdrawal limit
  • Pausable · ReentrancyGuard · SafeERC20
GravToken
  • ERC-20 with source decimals
  • Mint and burn only through BRIDGE_ROLE
  • No public mint function
  • Pausable transfers
GravBridge
  • Messenger-agnostic transport
  • Inbound only from the configured messenger
  • Nonce replay protection
  • Route registry per asset
Messenger
  • IGravMessenger boundary
  • LayerZero OApp or native messenger pluggable
  • Not deployed yet — bridge stays inert
  • Fee quoted by the messenger itself

Contracts are experimental until independently audited. · Foundry test suite: 33 tests incl. 3 invariants.
