# Arbitrum One

> Everything a program can name on Arbitrum One, and how a program writes each name.

**Preview chain.** Sauce supports transactions on Ethereum, Base, Arc and Solana, and the testnets Arc Testnet, Base Sepolia, Ethereum Sepolia, Solana Devnet and Solana Testnet only. On Arbitrum One a program
compiles (`sauce compile`) and the reads work (`sauce globals`, `sauce price`, `sauce pools`),
and `sauce simulate` runs wherever the release is deployed on the chain, but the `sauce`
command and the MCP server build and send no transaction: `sauce tx`, `sauce run` and
`sauce pot --deploy` are refused,
naming this chain and the supported chains: the last section shows the refusal and how to
request this chain.

| Fact | Value |
| - | - |
| Support | preview: compile and read; no transaction is built or sent |
| Slug (`--chain`) | `arbitrum`; also `arb` |
| Chain id | 42161 |
| Kind | EVM |
| Name in a program | `Arbitrum` |
| In TypeScript | `import { Arbitrum } from "@eco-incorp/sauce"`: its tokens and protocol namespaces are properties of it |
| Native coin | ETH (Ether), 18 decimals |
| Sauce | the engine, Kitchen and Routers, at the same addresses on every EVM chain: [Deployments](https://docs.eco.com/sauce-sdk/reference/deployments.md) |
| CCTP domain | 3 |

## In a program

Compiled with `--chain arbitrum`, a program names Arbitrum One's tokens and contracts with no
import; the same file compiled for another chain resolves each name there, or fails where the
chain does not have it.

```ts theme={null}
function main() {
  // `USDC` is Arbitrum One's USDC: `0xaf88d065e77c8cC2239327C5EDb3A432268e5831`.
  const held = USDC.balanceOf(pot);
  // `Token(address)` is any other ERC-20, and works for a symbol's address too.
  require(Token(USDC).balanceOf(pot) == held);
  // `AaveV3.Pool` is Arbitrum One's pool: `0x794a61358D6845594F94dc1DB02A252b5b4814aD`.
  require(AaveV3.Pool != 0);
  // The same contract, qualified by the chain's name, from a program on any chain.
  require(Arbitrum.AaveV3.Pool == AaveV3.Pool);
}
```

## Tokens

| Symbol | Address | Decimals |
| - | - | - |
| `USDC` | `0xaf88d065e77c8cC2239327C5EDb3A432268e5831` | 6 |
| `USDT0` | `0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9` | 6 |
| `WETH` | `0x82aF49447D8a07e3bd95BD0d56f35241523fBab1` | 18 |

## Protocols

Every protocol the registry records here, each contract with how a program names it: its
namespace contract, or its ABI imported from `./protocols/<slug>/<Export>.json` and bound to the
address.

## Requesting support

On Arbitrum One, `sauce tx`, `sauce run` and `sauce pot --deploy` exit with status 1 before
they reach an endpoint or read a key. The first line `sauce tx` prints is:

```text theme={null}
sauce tx: building the cook transaction is refused: it involves arbitrum (Arbitrum One, chain id 42161), a preview chain. The sauce command and its MCP server build and send transactions only on Ethereum, Base, Arc and Solana, and the testnets Arc Testnet, Base Sepolia, Ethereum Sepolia, Solana Devnet and Solana Testnet. On a preview chain they build and send none. A program still compiles there and globals, price, pools and pot's prediction still read; simulate runs wherever the release is deployed on the chain, and says so where it is not.
```

To request Arbitrum One, contact Eco through [Support and community](https://docs.eco.com/resources/support.md),
naming the chain and its id (Arbitrum One, 42161) and what you want to run there.

## Next steps

* [Chains](https://docs.eco.com/sauce-sdk/reference/chains.md): every other chain, with its support.
* [Names and registries](https://docs.eco.com/sauce/names.md): how a name in a program becomes an address on the chain it is compiled for.
* [Glossary](https://docs.eco.com/sauce/glossary.md): the words these pages use, in plain terms.
