WrapfiDocumentation

Bridge

Wrap locks collateral on Ethereum and mints wrapped tokens on Robinhood Chain. Unwrap burns wrapped tokens and releases the original asset back on Ethereum.

Wrap flow

  1. Deposit a supported asset into the Wrapfi adapter vault on Ethereum.
  2. The adapter sends a LayerZero message to the wrapped OFT on Robinhood Chain.
  3. The OFT mints wrapped tokens 1:1 against locked collateral, minus the wrap fee.

Unwrap flow

  1. Burn wrapped tokens on Robinhood Chain through the OFT contract.
  2. LayerZero delivers the release message to the Ethereum adapter.
  3. The adapter returns underlying tokens to your wallet, minus the unwrap fee.

Fees on bridge transactions

  • Wrap fee: 0.1% of the bridged amount
  • Unwrap fee: 0.1% of the bridged amount
  • LayerZero native fee: quoted per transaction in ETH
  • Transfer tax on wrapped tokens: 0%

Security stack

Bridge messages require two active DVNs: LayerZero Labs and Nethermind. An earlier BitGo DVN configuration was replaced because it was dormant on Robinhood Chain and caused stuck messages. See the LayerZero page for troubleshooting guidance.

What the app reads on chain

The Wrap page discovers assets from the Robinhood Chain asset registry. Per asset adapter and OFT addresses are loaded dynamically. Do not hardcode token addresses from older deployments. Use the Contracts page for the current wired set.
