Challenge

Every bridge has to answer one question: who has to lie for it to fail? For Robinhood Chain the answer is nobody — because there is no separate validator set.

Solution

Withdrawals take a 45,818-block challenge period on Ethereum — about 6.4 days.

Results

Deposits: ~10 minutes, via the Delayed Inbox at 0x1A07cc4B…7a2D.

  • No guardian set, no multisig, no third-party validator.
  • The full flow is executable from any wallet — see /bridge.
  • The chain produces about ten blocks per second, and a block carries about eight transactions.
  • Gas is paid in ETH; the median base fee across the last twelve million blocks was 0.0225 gwei.
