# Index token contracts > Every Bankr index token contract on Base and Robinhood Chain, with its address and ABI. # Index token contracts Every contract behind Bankr index tokens, on each chain, with its ABI. This page is generated from the deployment records, so it matches what is on chain. [Index tokens for developers](/token-launching/index-tokens-for-developers) shows how to use them. **Machine-readable:** [contracts.json](https://docs.bankr.bot/index-tokens/contracts.json) lists every address below with its ABI's URL and keccak256 hash. ## Base Chain ID `8453`. Deployed at block `52696524` from contracts commit `5bef98481e`. Addresses link to Basescan. ### Contracts | Contract | Address | What it does | ABI | | --------------------------- | ----------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------- | | IndexFactory | [`0x49a3A6D33110425099A9f070d22f576f592b46eB`](https://basescan.org/address/0x49a3A6D33110425099A9f070d22f576f592b46eB) | Creates indexes: checks the basket, clones a vault, registers its two pools and makes the first buy. `IndexCreated` announces each index; `isVault` checks an address. | [IndexFactory.json](https://docs.bankr.bot/index-tokens/abis/IndexFactory.json) | | IndexHook | [`0x2Fd0ba044Faa96A9d1B0f010C0Dac3F696aA2888`](https://basescan.org/address/0x2Fd0ba044Faa96A9d1B0f010C0Dac3F696aA2888) | The Uniswap v4 hook on every index pool.
