Arbitrum will direct 10% of transaction fees generated on Robinhood Chain and other Arbitrum Layer 2 platforms into its ecosystem, with 8% allocated to the Arbitrum treasury controlled by token holders and 2% funding development initiatives, according to Offchain Labs co-founder Steven Goldfed.
The fee-sharing arrangement establishes a revenue stream for the Arbitrum ecosystem while maintaining incentive alignment with ARB token holders who govern the treasury. By contrast, 100% of fees collected on Arbitrum One, the protocol's primary mainnet, continue flowing directly to the Arbitrum treasury without distribution to other platforms.
The structure underscores Arbitrum's multi-chain strategy, where subsidiary Layer 2 solutions like Robinhood Chain contribute to a shared ecosystem fund rather than operating as entirely independent revenue entities. This approach allows the protocol to expand its deployment footprint while consolidating financial resources for ecosystem growth under token-holder governance.
