What works
This page exists so nobody has to guess. It is written in the same words the interface uses, and it is wrong on purpose in no direction: if something here says it is unfinished, it is.
You can do this
- Read every listed asset with its issuer, contract and decimals, checked against the chain.
- Read US stock prices published by Pyth, each with the time it was published.
- Open a market for a candlestick chart of the stock itself, labelled as delayed.
- Connect a wallet and read your balances over our own connection to Arc Testnet.
- Send any listed asset from the portfolio page, rehearsed against the chain first.
You cannot do this yet
- Swap. Routing needs Uniswap v4 at the addresses we are configured with. On Arc Testnet the check comes back empty, so the panel refuses to quote and the endpoints answer
503with the missing contract names. Nothing is hidden behind that message and nothing can be signed. - Launch a coin. The launchpad is in development.
- Trade a perpetual. Perpetuals are in development.
- Buy a stock. Not here, and not as a share. There are no tokenized stocks on Arc. Where Specie ties a market to a stock, the tie is an oracle price.
The network this build points at
| Network | Arc Testnet |
| Chain id | 5042002 |
| Mode | testnet |
| Quote asset | USDC |
| Listed against it | EURC, USYC |
Circle had not published the mainnet parameters when this build was made. The network, the RPC and the contract addresses all come from configuration, so switching is a config change and not a new release. Until the switch, treat every number on the site as testnet.
What we will not say
No volume, no user count and no liquidity figure appears anywhere on this site, because we have none worth naming. No part of the product is described as working before it works. If you find a sentence that breaks either rule, it is a bug.
