> ## Agent Instructions
> SODAX is mainnet-only (no testnet chains or RPC endpoints exist) with a hub-and-spoke architecture; Sonic is the hub. SODAX is non-custodial protocol/software: it routes and settles; independent solvers on the marketplace fill — never say 'our solver', 'the SODAX solver', that SODAX trades, takes custody, or fills orders. For frontend/React integrations, prefer @sodax/dapp-kit hooks over calling @sodax/sdk directly. SDK operations — the methods that build, submit or await a transaction, and the API/quote calls — return Result<T, E> ({ ok: true, value } or { ok: false, error }): check result.ok, never wrap them in try/catch or branch on error.message; discriminate on the narrow error.code union instead. Synchronous config getters (getPartnerFee, getSupportedSwapTokens, getVault, ...) return their value directly, not a Result.

# Base: Networks & Assets

> What is live on Base today, and the networks and assets your users can reach from it.

Base is a spoke network in the SODAX System. User funds stay on Base; the hub (Sonic) coordinates execution, and solvers settle against deep native liquidity on each network rather than isolated bridge pools.

There are two asset lists to keep straight, and the difference is the point of SODAX:

* **Assets on Base**: the <span data-sodax-config="count" data-metric="chain-swap-tokens" data-chain="0x2105.base">11</span> assets that live on Base itself, ETH and ERC-20 tokens. These are what your users hold, send, and receive on Base; the entry and exit points of any Base-side flow.
* **Assets across the SODAX System**: <span data-sodax-config="count" data-metric="swap-tokens">166</span> assets across all supported networks. Every one of them is a valid swap destination or collateral source for your Base users, because every SODAX action is cross-network by default.

A user holding ETH on Base is not limited to the Base-side list. They can swap it into USDC on Arbitrum, SOL on Solana, or any other listed asset on any network, in one signed transaction. The on-Base assets are simply where those journeys start and end on your side.

Every count and list below is read live from the backend config API, `GET https://api.sodax.com/v2/be/config/all`, so it reflects what the backend serves today rather than what an SDK release has listed.

## Assets on Base

Live for swaps on Base:

<div data-sodax-config="swap-tokens" data-chain="0x2105.base">
  Live token list loads from the config API. If it has not appeared, read `config.swaps.supportedTokens["0x2105.base"]` from [`GET /v2/be/config/all`](https://api.sodax.com/v2/be/config/all), or use the SDK call below.
</div>

Live in the [Money Market](/base/money-market) for supply, borrow, repay, and withdraw:

<div data-sodax-config="money-market-tokens" data-chain="0x2105.base">
  Live token list loads from the config API: `config.moneyMarket.supportedTokens["0x2105.base"]` in [`GET /v2/be/config/all`](https://api.sodax.com/v2/be/config/all).
</div>

ETH uses the zero address. Every other address is the token's ERC-20 contract on Base mainnet, which you can look up on Basescan, the explorer listed in [Connect to Base](https://docs.base.org/get-started/connect-to-base).

Hub vault addresses per asset are listed in [Swaps: Compatible Assets](/developers/deployments/swaps-compatible-assets).

## Assets your users can reach

From a Base-sourced action, users can trade, lend, and borrow across every SODAX-supported network:

<div data-sodax-config="chains">
  Live network list loads from the config API: `config.chains` in [`GET /v2/be/config/all`](https://api.sodax.com/v2/be/config/all).
</div>

Chain identifiers come from `ChainKeys.*` in the SDK (`ChainKeys.BASE_MAINNET` = `'0x2105.base'`), and the live chain list from `sodax.config.getSupportedSpokeChains()`. Prefer the config call over hard-coding: networks are added over time.

## Asset discovery in code

Never hard-code token addresses or asset lists; read them from the SDK config at runtime:

```typescript theme={null}
import { Sodax, ChainKeys } from '@sodax/sdk';

const sodax = new Sodax();

// Swappable assets on Base
const swapTokens = sodax.swaps.getSupportedSwapTokensByChainId(ChainKeys.BASE_MAINNET);

// Money market assets on Base
const mmTokens = sodax.moneyMarket.getSupportedTokensByChainId(ChainKeys.BASE_MAINNET);
```

These lists ship with the SDK package, so a token the backend has added since your SDK release appears in the live tables above before it appears here.
