# Base and Robinhood Chain

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

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

Feel.cash brings supported markets into one cash-native experience. The market can live on another chain while Cash and payouts use USDC on Base.

## Base

Base is Feel.cash's settlement layer.

| Property              | Value                             |
| --------------------- | --------------------------------- |
| Chain ID              | `8453`                            |
| Explorer              | [BaseScan](https://basescan.org/) |
| Cash and payout asset | USDC on Base                      |
| Opening FDV target    | Approximately $10,000             |
| Default pool pairing  | WETH                              |

Launch payments, Creator Fees, Referral Fees, deposits, and withdrawals settle through Base USDC. Feel.cash handles the necessary routing so users can work from one Cash balance.

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.

For X launches, [pairing, chain requests, and account eligibility determine the network](/launch/x-launcher.md#what-if-i-do-not-name-a-chain).

## 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                                                      |
| Cash and payouts     | USDC on Base                                                         |
| 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.

## Solana

Solana launches are coming soon. Portfolio or indexed-token support does not mean new Solana launches are available today.

For the difference between a Solana stock representation, its issuer, and an available market, read [tokenized stocks on Solana explained](/stocks/solana-tokenized-stocks.md).
