# Yield Xyz Agentkit Robinhood

> The Robinhood Chain connector for the Yield.xyz AgentKit — adds Robinhood Chain (mainnet, chain ID 4663) configuration, wallet setup, and supported capabilities. Extends the yield-xyz-agentkit skill — that skill discovers yields and builds the unsigned transactions; signing and broadcasting on Robinhood Chain are identical to any other EVM chain. Use when the user wants to set up Robinhood Chain…

## About

# Yield.xyz AgentKit × Robinhood Chain

The **Robinhood Chain connector** for the Yield.xyz AgentKit: it adds the Robinhood Chain (mainnet) configuration the rest of the kit needs, and points your existing EVM signer at the chain. Robinhood Chain is an Arbitrum Orbit L2 (chain ID `4663`) with ETH as its gas token.

`yield-xyz-agentkit` (this skill's base) owns all yield logic — discovery, schemas, validator selection, balances, building `unsignedTransaction` (`actions_enter` / `actions_exit` / `actions_manage`), output formatting, and the MCP tool reference. Use it for all of that; this skill only adds Robinhood Chain configuration and funding guidance.

**Robinhood Chain is an EVM network, so signing and broadcasting are identical to any other EVM chain** — this skill does not hold keys, sign, or broadcast. Bring your own EVM signer (a user's wallet, your agent's custody, or a connector like Privy).

```
Robinhood Chain     → configure chain (RPC + chainId) + fund wallet (bridge ETH + deposit token)
yield-xyz-agentkit  → discover yield + build unsignedTransaction
Your EVM signer     → sign + broadcast (same as any EVM chain)
yield-xyz-agentkit  → submit_hash + poll get_transaction
```

---

## CRITICAL

- **Never modify `unsignedTransaction`** before signing — not addresses, amounts,
  fees, or encoding. If anything looks wrong, have `yield-xyz-agentkit` build a NEW
  action. Modifying it **will result in permanent loss of funds**.
- **Never call the Yield.xyz API directly** (curl/HTTP) — it requires an API key
  and returns `401`. All Yield.xyz access goes through the MCP (handled by the
  `yield-xyz-agentkit` skill).
- **Mainnet.** Robinhood Chain here is mainnet (chain ID `4663`); gas is paid in
  **ETH**. Match yields and balances by the deposit token's contract address, not by
  symbol. See `references/chain-config.md`.

---

## Prerequisites

- **Yield.xyz AgentKit MCP** connected (owned by the `yield-xyz-agentkit` skill).
- **An EVM signer** able to sign and broadcast on Robinhood Chain mainnet.

If the MCP is missing, stop and tell the user. See `references/setup.md` for
connection instructions.

## Full Flow

### Step 1 — Configure Robinhood Chain

Point your signer at Robinhood Chain mainnet using the RPC URL and chain ID in
`references/chain-config.md`, and confirm the network resolves on Yield.xyz. See
`references/setup.md`.

### Step 2 — Fund the deposit token

An enter needs the yield's deposit token in the wallet, plus **ETH** for gas. Bridge
the deposit token and ETH onto the chain (canonical Arbitrum bridge, Robinhood
Wallet, or a supported route). Check the balance first and only bridge what you need.
See `references/chain-config.md`.

### Step 3 — Discover + build (via `yield-xyz-agentkit`)

Hand off to the `yield-xyz-agentkit` skill to discover the yield on Robinhood Chain,
inspect its schema, select a validator if required, and build the action — passing
the signer's wallet address. It returns `transactions[]` ordered by `stepIndex`.

### Step 4 — Sign and broadcast

Execute each transaction in `transactions[]` **sequentially**, in `stepIndex` order —
never in parallel, never out of order. (Step 5 covers when N is done and N+1 may begin.)

### Step 5 — Record the result

After the signer broadcasts each transaction, hand back to `yield-xyz-agentkit` to
record the hash (`submit_hash`, **mandatory**) and poll it to a **terminal status**
before signing the next — terminal-state semantics are defined in the base skill.
Never begin transaction N+1 until the current one resolves.

When all transactions confirm, have `yield-xyz-agentkit` fetch `yields_get_balances`
and show the user their new position.

## Error Handling

| Situation | Action |
|---|---|
| Yield.xyz MCP not connected | Register it — see `references/setup.md` |
| Robinhood Chain not resolving on Yield.xyz | Confirm the network slug (`robinhood`) in `references/chain-config.md` |
| No deposit-token or ETH (gas) balance | Bridge it onto the chain — see `references/chain-config.md` |
| Transaction FAILED | Do not retry automatically — report to user with txHash |

(For Yield.xyz-side errors — wrong arguments, rate limits — see the
`yield-xyz-agentkit` skill.)
