The route
The bridge moves FROTH between Flow EVM (chain 747) and Robinhood Chain (chain 4663) over LayerZero V2 as an OFT, lock-and-mint in both directions. Canonical FROTH locks in the adapter on Flow and the Robinhood leg mints; bridging back burns the Robinhood leg and unlocks on Flow. This is the only place the app touches Flow. Everything else lives on Robinhood Chain.
How to bridge
- 1Open /bridge and pick a direction. Your wallet will be prompted to switch to the source chain.
- 2Flow → Robinhood only: approve the bridge adapter to spend your FROTH (one transaction). The return direction burns directly, so no approval is needed.
- 3Enter the amount and confirm. The quote includes the LayerZero message fee, paid in the source chain's gas token.
- 4Track delivery on LayerZeroScan. The app links your transaction as soon as it's sent.
Dust truncation
The OFT uses 6 shared decimals across chains, so amounts are truncated to that granularity before sending. The app does this for you, so what you see sent is exactly what arrives. Sub-dust remainders never leave your wallet.
Timing
Flow → Robinhood usually lands in a few minutes. The return leg takes longer because of extra confirmations. Expect 15 minutes or more, and check the LayerZeroScan link if you want to watch it move.
