# Chains

Understand Base, Robinhood Chain, Arc, and Solana in Feel.cash, including launch pairings, supported markets, and settlement in Cash.

**Cash first. Chains behind the scenes.**

Feel.cash brings supported markets into one cash-native experience. The market can live on another chain while payouts arrive in your Cash balance.

## Base

Base is Feel.cash's primary launch and trading network.

| Property             | Value                             |
| -------------------- | --------------------------------- |
| Chain ID             | `8453`                            |
| Explorer             | [BaseScan](https://basescan.org/) |
| Payouts              | Your Cash balance                 |
| Opening FDV target   | Approximately $10,000             |
| Default pool pairing | WETH                              |

Launch payments, Creator Fees, Referral Fees, deposits, and withdrawals all use one Cash balance. Feel.cash handles the necessary routing.

Base launches default to WETH. Creators can select USDC when they prefer a dollar-denominated pair. Feel.cash recommends WETH for creators seeking more price movement; USDC removes movements in ETH/USD from the pairing. The final choice is visible before signing and becomes immutable at launch.

Base also supports tokenized-stock pairings, including Apple (`AAPLc`) and NVIDIA (`NVDAc`). See the [company catalog](/stocks/catalog.md) for current choices.

## Robinhood Chain

Feel.cash also supports markets on Robinhood Chain.

| Property             | Value                                                                |
| -------------------- | -------------------------------------------------------------------- |
| Chain ID             | `4663`                                                               |
| Explorer             | [Robinhood Chain Blockscout](https://robinhoodchain.blockscout.com/) |
| Market               | Robinhood Chain                                                      |
| Payouts              | Your Cash balance                                                    |
| Opening FDV target   | Approximately $10,000                                                |
| Default pool pairing | WETH                                                                 |

Cross-chain trades can take longer than Base-only trades. Feel.cash routes supported buys from Cash into the market and supported sells back to Cash.

### Stock pairings

Robinhood Chain launches default to WETH. They can also be paired with a tokenized stock when that option appears in the launch form. A pairing is hidden when its price feed or settlement route is not healthy enough for a new market.

A tokenized stock pairing is an onchain asset, not the underlying share itself. Availability and executable quotes can change with market hours, price-data freshness, paused assets, and route conditions. Review the asset and issuer information shown in the launch or trade flow before signing.

## Arc

Feel.cash also supports markets on Arc, Circle's chain.

| Property             | Value                                                             |
| -------------------- | ----------------------------------------------------------------- |
| Chain ID             | `5042`                                                            |
| Explorer             | [Arc Explorer](https://explorer.arc.io/)                          |
| Market               | Arc                                                               |
| Payouts              | Your Cash balance; EURC and cirBTC pairings can pay in that asset |
| Opening FDV target   | Approximately $10,000                                             |
| Default pool pairing | USDC                                                              |

You launch and trade Arc coins from your Cash balance, as on Robinhood Chain. Feel.cash routes supported buys from Cash into the market and supported sells back to Cash, and cross-chain trades can take longer than Base-only trades.

### Arc pairings

Arc launches default to USDC. Creators can select EURC (a euro stablecoin) or cirBTC (bitcoin) instead. Arc has no WETH or tokenized-stock pairings. The final choice is visible before signing and becomes immutable at launch.

| Who earns                   | USDC pairing | EURC or cirBTC pairing    |
| --------------------------- | ------------ | ------------------------- |
| Me, or a selected X account | Cash         | Cash, or the paired asset |
| Holders                     | USDC         | The paired asset          |

EURC and cirBTC you earn appear in your portfolio, where you can sell them for Cash. A dev buy is available with the USDC pairing.

## Solana

Feel.cash also launches coins on Solana.

| Property             | Value                          |
| -------------------- | ------------------------------ |
| Explorer             | [Solscan](https://solscan.io/) |
| Market               | Raydium                        |
| Opening market cap   | Worth about 28 SOL             |
| Default pool pairing | SOL                            |

A Solana coin starts on a bonding curve and then moves to a standard liquidity pool. It can be paired with SOL, USDC, or a tokenized stock.
