Deployed contracts

FX’s V6 revision 6 contracts are deployed on Arc mainnet, chain ID 5042. Use this page to identify the release and connect to its onchain interfaces.

The public app and indexed market API are not hosted yet. At the latest release check, new launches were paused and official FX was not registered. Direct contract reads are available.

Network

Setting	Value
Network	Arc mainnet
Chain ID	`5042`
Public RPC	`https://rpc.mainnet.arc.io`
Explorer	Arc Explorer
Native gas asset	USDC
Release ID	`arc-mainnet-r6-f66530bb`
Deployment start block	`21239186`

See Arc’s network setup for wallet configuration. Arc exposes native USDC at 18-decimal precision and its ERC-20 interface at 6 decimals. They represent the same balance; do not count them as separate assets.

Core contracts

Component	Arc mainnet address
Uniswap v4 PoolManager	`0x8366a39CC670B4001A1121B8F6A443A643e40951`
Currency-pool registry	`0x214c9023034b1e31D024c8084AF0e4151E659Bf2`
Token factory	`0x95067766eF16f7849942185AD12de1816d3c3C2C`
FX hook	`0xc555d361dEe2062A0560678D3f663784887265Cc`
Canonical positions	`0x5580191B3F867Fb5B5EDdA52cb3FE8010a48949F`
Launch deployer	`0x02D1a2387f97CD124D8e7f7Fb3c0eD58Bb3E76f8`
Router	`0x36A99B29dE4B186Ca8fC70ca95c3CB45596ACBE4`
Quoter	`0x04B9d79AEaB5d3a5a568994122317c9753C1d627`
Market lens	`0xce3Cfd35c59eF9C3c2F68c3eF4E3Cf9123B9a935`

The router is the spending target for the documented trading flow. The quoter simulates execution; it does not hold a spending allowance. Use the matching R6 ABI and check quote and settle before constructing an order.

Revenue and policy

Component	Arc mainnet address
Revenue vault	`0xc89d0a58b4DaA9aAd99315A3D8C8dcB83e875A56`
Revenue collector	`0x92a66BDFa306E16db38E65976d4a6d9F4fd67f88`
Conversion registry	`0x04284F8713426867Ea3ea7F2556ba5DB994bc447`
Buyback executor	`0xe84aA2B1Ca63749C6569adAf368AB642c08ABf80`
Liquidity observations	`0x3914e82Ed6fdbb7DccFDad0310278575340e7b44`
Release policy	`0x9828DadEa3D438D2566fCeb85F245089C1E6C39c`

See architecture for each component’s role and production settings for the installed policy.

Currencies and pair

Asset	ERC-20 decimals	Arc mainnet address
USDC	6	`0x3600000000000000000000000000000000000000`
EURC	6	`0xbEf5f6d51CB62b58e6A8f77868681825C6fe21c1`

Both quote assets and the EURC/USDC relationship were enabled at the documented snapshot. New launches remain subject to the separate global pause and current admission checks. The registry’s pair ID is:

0xec255c898470f77aaf513f8f692d75de66b4bc973fcb01907b9d24b1562d53d4

The admitted external currency pool uses this PoolKey on the PoolManager above. Its fee value is in parts per million: 500 means 0.05%.

{
  "currency0": "0x3600000000000000000000000000000000000000",
  "currency1": "0xbEf5f6d51CB62b58e6A8f77868681825C6fe21c1",
  "fee": 500,
  "tickSpacing": 10,
  "hooks": "0x0000000000000000000000000000000000000000"
}

The relationship is discovered through the registry. An empty pairs array in the deployment manifest is intentional when registryDiscovery is enabled; it does not mean the registry has no admitted pair.

Read the current state

This example uses viem and makes read-only requests to the public Arc RPC. It does not need a wallet.

import { createPublicClient, http, parseAbi } from 'viem';

const client = createPublicClient({
  transport: http('https://rpc.mainnet.arc.io'),
});

if (await client.getChainId() !== 5042) {
  throw new Error('Expected Arc mainnet');
}

const registry = '0x214c9023034b1e31D024c8084AF0e4151E659Bf2';
const factory = '0x95067766eF16f7849942185AD12de1816d3c3C2C';
const blockNumber = await client.getBlockNumber();

const abi = parseAbi([
  'function launchesPaused() view returns (bool)',
  'function protocolToken() view returns (address)',
  'function count() view returns (uint256)',
]);

const [launchesPaused, protocolToken, tokenCount] = await Promise.all([
  client.readContract({
    address: registry, abi, functionName: 'launchesPaused', blockNumber,
  }),
  client.readContract({
    address: factory, abi, functionName: 'protocolToken', blockNumber,
  }),
  client.readContract({
    address: factory, abi, functionName: 'count', blockNumber,
  }),
]);

console.log({
  block: blockNumber.toString(),
  launchesPaused,
  protocolToken,
  tokenCount: tokenCount.toString(),
});

A zero protocolToken address means official FX has not been registered. Read the factory again after registration; a token’s name or symbol does not establish official status. The live FX proxy at https://fx.meme/api/rpc accepts approved JSON-RPC read requests. It is a read service, not a signing or transaction-submission endpoint.

Release manifest

All 15 contract code hashes below matched the mainnet bytecode at block 21,240,866. Explorer links identify the contract accounts; source-code verification by an explorer is a separate property. The fingerprint is Keccak-256 of the UTF-8 compact JSON serialization of the release object, with object keys sorted recursively and array order preserved. Pin the expected fingerprint independently of responses that supply market data.

For the documented snapshot, the release policy’s onchain policyHash() was:

0xb5acf5711c9e76b4851f46074c42c4ad25ddb7a3c50405e1fd4b72fea4bf5378

The release fingerprint covers the manifest. The policy hash covers the constructor-selected opening and buyback settings. They identify different data and should not be interchanged.
