# Torinox Protocol deployment and verification reference

Verification date: 2026-09-06 UTC

## Live deployment

- Network: Robinhood Chain mainnet
- Chain ID: `4663`
- Oracle: `0xd8a0680e7699526b57140ed4eafdcc7219dc0a0c`
- Provider: `0x8741b8a825644D9Ef18Faf2DAB5e9b47B900F2b6`
- Exact fee for `getFeeV2(provider, 200000)`: `25000000000000` wei (`0.000025 ETH`)
- Refund delay: `6` L1 blocks
- Provider callback default: `200000` gas
- Registered provider chain end: `500003`; next request sequence observed during verification: `566`
- Runtime code hash: `0x25133ee28778728ac5825c0da67863eaef8d40b6b5306b28c9f70c30b4daa118`
- Blockscout reports the address as a verified, non-proxy `TorinoxEntropy` contract.

## Reproduce a completed result

A completed result can be recomputed with the public contributions using Foundry `cast`:

```bash
USER_CONTRIBUTION=cf20518c5c930094398343eaf8f2692dbe8b1a0a8d142ff32cad69fbcb6828ea
PROVIDER_CONTRIBUTION=cac94c1dc902ce96ca415fc5a70e34fcd661c2092a45e2533e0aa5b1c85dc2f8
ZERO_BLOCKHASH=$(printf "%064d" 0)
cast keccak "0x${USER_CONTRIBUTION}${PROVIDER_CONTRIBUTION}${ZERO_BLOCKHASH}"
```

Expected output:

```text
0x058a22e6c8f170925b26c7c28418d9659801428436616d81f4d66ca0f38fa169
```

This corresponds to:

- Sequence: `565`
- Reveal transaction: `0xb3e0d0e7d6d89b9d668867982314f0036247e340fcb8042a41d67b04d91a3155`
- Formula: `keccak256(abi.encodePacked(userContribution, providerContribution, bytes32(0)))`

## What this proves

- A contract exists at the stated address on chain 4663.
- Blockscout has verified source for that deployed address.
- The checked fee, provider, refund delay, callback default, and provider sequence values were readable onchain on the verification date.
- The selected completed reveal recomputes exactly from its public contributions.

## What this does not prove

- Source verification is not an independent security audit.
- Deployment existence and one reproducible reveal are not a reliability percentage or SLA.
- A refund restores the exact request fee but not transaction gas and does not produce a random result.
- The designated provider can withhold after learning a would-be output. Applications need a defined no-reveal policy.
