# Tokens on Arc Mainnet Arc supports stablecoins, tokenized assets, and tokens created by applications and their users. **Biscotti Finance** provides a DEX and token launchpad for trading and creating tokens on Arc Mainnet. Use this guide to identify a token by its network and contract address, understand its role, and find the appropriate trading or launch guide. ## Arc Mainnet token addresses These are the assets recorded in Biscotti's [mainnet deployment reference](/developers/addresses). They are a starting list, not a complete directory of every token on Arc. An address in this table does not mean that every pair has liquidity on Biscotti. | Token | Role | Arc Mainnet contract address | | --- | --- | --- | | USDC | US dollar stablecoin and Arc's gas currency | `0x3600000000000000000000000000000000000000` | | EURC | Euro stablecoin | `0xbEf5f6d51CB62b58e6A8f77868681825C6fe21c1` | | USYC | Tokenized fund asset | `0x8a5D989Bbb96929F689B0200f435f53dA42bF490` | | cirBTC | Circle Wrapped Bitcoin | `0x171A4217b86A807A64eB94757Db6849fb4bDbAA0` | Arc's [mainnet launch announcement](https://www.arc.io/blog/arc-economic-os-internet) describes the Circle assets available in the ecosystem. Asset-specific transfer or access rules still apply. ## Check a token before importing it A token symbol is not a unique identifier. Different contracts can use the same name or symbol, and the same symbol can appear on several networks. 1. Confirm that your wallet is on Arc Mainnet, chain ID `5042`. 2. Copy the contract address from the issuer or the relevant deployment record. 3. Look up that address in [Arc Explorer](https://explorer.arc.io) and check the contract and token details. 4. Compare the address with the token selected in Biscotti before approving a transaction. For tokens created through Biscotti, use the token's launch page and the [launchpad contract reference](/launchpad/contracts) to identify its pool and contracts. The [launchpad safety guide](/launchpad/safety) explains the liquidity lock and the limits of that protection. ## How to trade Arc tokens Connect to [Biscotti Finance](https://biscotti.finance), select Arc Mainnet, and choose a pair in **Swap**. The quote depends on the liquidity available for the route and the size of your trade. Review the output amount, price impact, and slippage setting before confirming. Keep some USDC available for gas. See the [Arc Mainnet wallet guide](/arc-mainnet) for setup and the [swap guide](/swap) for how execution works. ## Create your own token on Arc The [Biscotti launchpad](/launchpad) creates a fixed-supply token with a USDC liquidity pool. All one billion tokens enter the launch pool, with no team allocation or presale. The liquidity positions remain locked in the vault. Creators choose between [Standard and Moon curves](/launchpad/curves) and select a [fee mode](/launchpad/fees). The launch flow can include an optional first purchase in the same transaction. ## BSCT, gas tokens, and testnet assets [BSCT](/token) is Biscotti's protocol reward token. It is separate from USDC, which pays for gas, and from the individual tokens created through the launchpad. The current BSCT deployment is on Arc Testnet; its mainnet rollout is tracked on the [Roadmap](/roadmap). Arc Testnet uses chain ID `5042002`. Its test tokens and contract deployments are separate from mainnet. Use the [testnet quick start](/quick-start) to experiment with swaps and rewards. ## Arc token and airdrop questions Finding a token on Arc, using a faucet, or holding BSCT does not establish eligibility for an Arc airdrop. Each reward program needs its own published rules. See [Arc airdrop questions](/arc-airdrop) for official information sources and the rewards documented by Biscotti.
