Scope: Summarize base-layer assumptions and constraints for the Hub rollup.

Known foundations

  • The Hub is an Arbitrum Orbit rollup (Rollup mode) that serves as a neutral entity registry and coordination layer, settling to Ethereum.
  • DCHUB is the native token used for gas and protocol governance, and for protocol-level fees where enabled.
  • Entities operate primarily in stablecoins; USDC on Ethereum bridged to the Hub is the baseline operating currency.
  • Canonical bridge gateways are the primary interoperability surface; no single external bridge is a dependency of kernel truth.
  • Optional modules extend the Hub; private execution zones are out of scope for Orbit v1.

Operating currency and asset conventions

  • Stablecoins on the Hub are canonical bridged ERC-20 contracts from Ethereum with a single canonical address recorded in the asset registry.
  • Reference interfaces should use mainstream symbols (USDC, USDT, DAI) and disclose bridge and issuer risk.
  • Protocol-level fees are DCHUB-denominated; applications may sponsor fees or charge separate off-protocol service fees in stablecoins.
