## Key Token Addresses

| Token                        | Address                                      | Standard |
| ---------------------------- | -------------------------------------------- | -------- |
| **USDC** (Native on Base)    | `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` | ERC-20   |
| **Conditional Tokens (CTF)** | `0xC9c98965297Bc527861c898329Ee280632B76e18` | ERC-1155 |

## Conditional Tokens

Limitless uses the [Gnosis Conditional Tokens Framework (CTF)](https://docs.gnosis.io/conditionaltokens/) — an ERC-1155 token standard that enables the creation of conditional outcome tokens for any future event. When a market is created, the CTF contract mints Yes and No tokens representing each outcome. These tokens are freely tradeable and composable with other DeFi protocols.

The CTF is the underlying primitive that powers all market mechanics on Limitless, including share merging/splitting, Negrisk conversions, and market resolution payouts.
