Chain
An Arbitrum Orbit L2 where tokenized US stocks are native assets with real Uniswap v3 pools.
The network
| Chain ID | 4663 (0x1237) |
| Stack | Arbitrum Orbit, settling to Ethereum |
| Gas token | ETH |
| Block time | around 100 ms |
| RPC | https://rpc.mainnet.chain.robinhood.com |
| Explorer | https://robinhoodchain.blockscout.com |
Any standard EVM wallet works. The app offers to add the network for you the first time you connect.
USDG
Pricing runs through USDG, the Global Dollar stablecoin issued by Paxos. It has six decimals, not eighteen — worth knowing if you are reading raw contract values rather than the interface.
Where the buying happens
Legs execute on the canonical Uniswap v3 deployment on this chain, across the 0.01%, 0.05%, 0.3% and 1% fee tiers. The app quotes every candidate route and takes the best one; it does not hold a fixed opinion about which pool is deepest, because that changes.
Clones exist. Several contracts on this chain imitate the Uniswap deployment. The addresses below are the canonical ones, all from the same deployer. Check them against the explorer rather than against a search result.

These tokens are issued by a third party, not by Crumble. We list what has a working pool and delist what stops having one; what that token is worth, and who stands behind it, is not ours to guarantee. See Risks.
