# POST /v1/yield/execute

> Submit a signed intent envelope for yield operations.

# POST /v1/yield/execute

<Note>**Free** — No payment required.</Note>

Submit a signed intent envelope for yield execution.
Rhaios validates the envelope (chain, merkle root/proofs, signer), runs a preflight simulation when enabled, and relays it to the configured bundler. Returns userOp hash, transaction hash, receipt, and position update.

When preflight simulation is enabled (`enforce` mode), the server creates an ephemeral [test RPC](/concepts/test-rpc) at the latest block, simulates the transaction, and only submits to the bundler if simulation succeeds. This prevents failed transactions from reaching the chain.

Duplicate execution calls for the same successful `intentId` are idempotent:

* First success returns `result: "executed"`.
* Later duplicates return `result: "already_executed"` with the original transaction hash.

## Parameters

<ParamField body="intentEnvelope" type="object" required>
  Signed-intent payload returned by `POST /v1/yield/prepare`, including `chainId`, `userOps`, `merkleRoot`, and `proofs`.
</ParamField>

<ParamField body="intentSignature" type="string" required>
  EIP-712 signature over `intentEnvelope.signing` generated by the same wallet as `intentEnvelope.userOps[0].userOperation.sender`.
</ParamField>

<ParamField body="intentId" type="string" optional>
  Optional alias for correlation. If provided, it must equal `intentEnvelope.merkleRoot`.
</ParamField>

## Example

```bash theme={null}
curl -X POST https://api.staging.rhaios.com/v1/yield/execute \
  -H "Content-Type: application/json" \
  -d '{
    "intentEnvelope": {
      "version": "1",
      "chainId": 8453,
      "userOps": [{ "userOperation": { "sender": "0x...", "nonce": "0x1", "callData": "0x...", "signature": "0x..." } }],
      "merkleRoot": "0x...",
      "proofs": [[]]
    },
    "intentSignature": "0x...",
    "intentId": "0x..."
  }'
```

## Response

```json theme={null}
{
  "executionModel": "erc4337-validator-intent-v1",
  "result": "executed",
  "userOpHash": "0x4f3e5a76d37bcfbfbd29652d4c26f20f39f84db4ec0d038df42f2f72e1e8b8a2",
  "txHash": "0x9c3ec6d6de7b3b4f0f6f19d9d8a73f0f9f77a17f5d5f3ea0c9f234569c0b8e72",
  "chainId": 8453,
  "chain": "base",
  "receipt": {
    "status": "success",
    "gasUsed": "241919",
    "blockNumber": 28430172
  },
  "explorerUrl": "https://basescan.org/tx/0x9c3ec6d6de7b3b4f0f6f19d9d8a73f0f9f77a17f5d5f3ea0c9f234569c0b8e72"
}
```

The `explorerUrl` links directly to the transaction on the block explorer for the chain used.
