CashCat Chain is a fast, low-cost EVM blockchain where CASHCAT is the money — every transaction fee is paid in CASHCAT, not ETH. It's an Arbitrum Orbit Layer 3 built on Arbitrum Nitro, settling to Robinhood Chain, and fully EVM-compatible.
This repository is the open-source codebase for the chain: the on-chain contracts (CCC bridge, LP staking), the off-chain services that operate them, node-operator configuration, and the canonical list of deployed addresses.

- CCC — the ecosystem token. Native on Robinhood Chain (
0xddeC0170…6615), bridged 1:1 onto CashCat Chain (0xf8bdba72…ed07) by the contracts incontracts/bridge. - CASHCAT — the native gas coin.
WCASHCAT(0x52E816c6…424B) is its ERC-20 wrapper. - DEX — a full Uniswap v2 / v3 / v4 deployment plus a Universal Router. All addresses
are in
deployments/cashcat-2274228.json.
