Specie in one page
Specie is a trading venue on Arc, the network Circle built for stablecoins. Swaps route through Uniswap or Aero, whichever pool pays more, and settle in a single transaction. Stock markets come after, priced by an oracle rather than by a token that does not exist.
How a swap settles
Quote from the pools, rehearsal against the chain, one signature, one transaction.
Prices and charts
Where every number on the screen comes from, and how old it is allowed to be.
API reference
The two public endpoints the interface itself uses, with every field named.
What this venue promises
Three rules hold everywhere in the product, and the rest of these docs is mostly the detail of keeping them.
- Nothing is held. A swap moves value out of your wallet and back into it inside one transaction. There is no deposit, no account and no balance of yours on our side.
- Nothing is signed unrehearsed. Every quote is simulated from your own address at the head block before the button arms, or checked by gas estimate when the simulator is down, and the panel says which. A check that does not come back clean leaves the button off and prints the reason.
- Every number carries its source. A price says where it came from and when it was published. An old number is labelled old rather than shown as current.
The shape of it
| Piece | State | What it does |
|---|---|---|
| Swap | Live | EURC, USYC, cirBTC, and WETH against USDC through Uniswap and Aero, fee 0.25% taken onchain. An asset without a pool says so instead of quoting. |
| Bring USDC | Live | USDC from eight chains to Arc through Circle CCTP, no Specie fee. How it works. |
| Stock prices | Readable | US stock price feeds from Pyth, each printed with its publish time. |
| Perpetuals | In development | Long or short a stock price with USDC margin. |
The interface says the same thing in the same words. If a panel offers something these docs call unfinished, the panel is wrong and we want to hear about it.
Reading these docs
What works is the honest status page: what a wallet can do on Arc right now and what it cannot. Network and assets has the chain parameters and every contract address we list. Risks and limits is the page to read before sending anything anywhere.
