# Production deployment
> The deployed Arc mainnet release, current availability, and verified execution settings.
**FX V6 revision 6 is deployed on Arc mainnet.**
The production contracts are onchain. The public app and indexed market API are not hosted yet.
Mainnet addresses, explorer links, the release manifest, and a read-only connection example.
Learn the currency choices, launch fee, allocations, and opening policy.
## Current availability
The onchain state below was verified at **block 21,240,866**, on **September 17, 2026 at 00:14 UTC**. Read the contracts again when preparing an operation; launch controls and token registration can change.
| Area | Verified state |
| --------------------------------- | ------------------------------------------------------------------ |
| Network | Arc mainnet, chain ID **5042** |
| Protocol contracts | V6 revision 6 deployed; all 15 manifest contract code hashes match |
| Quote currencies | USDC and EURC enabled |
| Currency relationship | EURC/USDC admitted through a hookless Uniswap v4 pool |
| New token launches | Paused: `launchesPaused() = true` |
| Tokens created by this factory | 0 |
| Official FX token | Not registered: `protocolToken()` returns the zero address |
| Public app and indexed market API | Not hosted yet |
| FX read-only RPC | Available at `https://fx.meme/api/rpc` |
Currency admission and launch availability are separate. The registry owner opens new launches; the current pause applies to FX-pair, single-currency, and dedicated official-FX launches.
## Deployment identity
| Field | Value |
| ---------------------- | -------------------------------------------------------------------------------------------------------------------------- |
| Release | `arc-mainnet-r6-f66530bb` |
| Factory | [`0x95067766eF16f7849942185AD12de1816d3c3C2C`](https://explorer.arc.io/address/0x95067766eF16f7849942185AD12de1816d3c3C2C) |
| Registry | [`0x214c9023034b1e31D024c8084AF0e4151E659Bf2`](https://explorer.arc.io/address/0x214c9023034b1e31D024c8084AF0e4151E659Bf2) |
| Revenue vault | [`0xc89d0a58b4DaA9aAd99315A3D8C8dcB83e875A56`](https://explorer.arc.io/address/0xc89d0a58b4DaA9aAd99315A3D8C8dcB83e875A56) |
| Deployment start block | [21,239,186](https://explorer.arc.io/block/21239186) |
| Gas asset | USDC |
The completed deployment records 23 successful transactions across blocks 21,239,186–21,239,239. The [contract reference](/developers/contracts) contains the complete manifest, including runtime code hashes and the release fingerprint.
## Deployed execution policy
These settings were read from the deployed `FXReleasePolicy` contract. That contract has no settings setters.
| Buyback setting | Deployed value |
| ---------------------------- | ----------------- |
| Minimum gross purchase | **100 USDC** |
| Fixed per-purchase maximum | None |
| Rolling one-hour spend cap | **1,500 USDC** |
| Rolling one-day spend cap | **6,000 USDC** |
| Minimum cooldown | **60 seconds** |
| Liquidity observation window | **3,600 seconds** |
| Maximum checkpoint age | **60 seconds** |
| Maximum execution impact | **350 bp / 3.5%** |
Reserved funds, remaining spend allowances, current and observed liquidity, execution pauses, and settlement bounds still limit each purchase. These settings do not promise a purchase schedule. Official FX must be registered before a buyback can execute.
The opening surcharge applies to **all launch types**: an initial **99%**, a nominal **500-millisecond half-life**, and expiry after **five seconds**. See [the opening window](/economics/opening-window) for fee bases and the chain-time calculation.
See [fees](/economics/fees) and [FX revenue](/economics/fx-token) for the fixed launch economics and 90/10 accounting.
## Currency and service availability
The deployed registry has USDC and EURC configured, and the admitted currency pool has a **0.05% native LP fee**. Exact identities are listed under [currencies and pair](/developers/contracts#currencies-and-pair).
Other currency-pair examples in these docs describe possible extensions. They are not additional enabled markets.
The live RPC proxy serves approved JSON-RPC reads. It does not provide the indexed `/api/markets` service or accept transaction submission. The [market-data reference](/developers/market-data) documents that separate service in preparation for hosting.
## Verification scope
The deployment record checks transaction receipts, component bindings, ownership, and deployed runtime code. The documentation's mainnet check independently matched all 15 manifest contract code hashes and read the launch gate, token registration, currency configuration, and release policy.
These checks establish the recorded deployment and settings. They are not an independent security audit or a guarantee of favorable market execution.
