SODAX for Robinhood Chain

No new contracts. SODAX’s Robinhood Chain spoke contracts are already live; your entire integration is TypeScript. Your users sign ordinary EVM transactions on Robinhood Chain, and SODAX coordinates cross-network execution, routing, and recovery behind the scenes.

You keep shipping on Robinhood Chain. SODAX absorbs the cross-network execution layer, so your product can offer trading and lending against every asset in the SODAX System, 166 across all supported networks, without leaving your stack. Integration happens in TypeScript, at the SDK or React layer. There is nothing to deploy, audit, or maintain on-chain. Using SODAX is free. Trades carry a fixed 0.1% base fee taken by the protocol, and you set your own platform fee on top. That part is fully yours, both the rate and the revenue. See Monetize SDK.

What to know on Robinhood Chain

Robinhood Chain is an Arbitrum Layer 2 with ETH as its gas token, and to the SDK a standard EVM network: the same EvmWalletProvider, ERC-20 approvals, and intent flow as any other EVM network. Four details are yours to know about:

Stock Tokens are swap-only. The live config lists Robinhood Stock Tokens, Robinhood’s tokenized stocks and ETFs, for swaps on Robinhood Chain. None of them is in the money market list. See Stock Tokens.
SDK 2.1.0 covers part of what is live. In @sodax/sdk 2.1.0, Robinhood Chain’s swap list holds only ETH, bnUSD, SODA, and USDG, and its money market list is empty. The SDK rejects Stock Token swaps and Robinhood Chain money market actions until the next release, which adds both; they are already on main.
Bring the chain definition for your own viem setup. The viem version SODAX pins has no Robinhood Chain entry, so @sodax/wallet-sdk-core exports one as robinhoodChain (chain ID 4663). @sodax/wallet-sdk-react already includes it.
The public RPC is rate-limited. The SODAX config uses https://rpc.mainnet.chain.robinhood.com, which Robinhood marks as rate-limited and not recommended for production. Pass a provider endpoint through rpcUrl.

What you can build

Two SODAX modules are relevant to Robinhood Chain builders:

Swaps

Intent-based cross-network swaps. Users swap between ETH or Robinhood Chain tokens and assets on any supported network with one signed transaction on Robinhood Chain. Solvers fill; SODAX routes and settles.

Money Market

Cross-network lending and borrowing. Supply from Robinhood Chain, borrow to Robinhood Chain or any other supported network. Needs the SDK release after 2.1.0.

Scope and build with AI

Point your AI coding assistant at the SODAX Builders MCP and it gains live access to the whole SODAX System: supported chains and tokens, real swap quotes, money market rates, intent history, and these docs. It works in Claude, Cursor, VS Code, Windsurf, and any other MCP-capable client.

Use it to scope before you commit: your assistant can read your own codebase, pull real quotes and token lists, and map exactly where SODAX fits in your product. Full tool list and per-client setup at builders.sodax.com.
