Contracts and events

Every deployed contract on Arc mainnet, and the events to index launches and swaps.

All addresses below are also committed to the repo as deploy artifacts, and the app builds from the same registry, so this page and the running product cannot silently disagree. Explorer: explorer.arc.io.

Arc mainnet (chain id 5042)

Deployment block 12226732. Start your indexer there; nothing of ours exists before it.

v3 on Arc mainnet

v3 tokens run on contracts of their own, deployed at block 26403042; the ones above did not change. Every v3 token mints a fixed 1 billion.

Events worth indexing

These are what our own indexer scans. All pool-scoped events are keyed by the v4 poolId (bytes32).

New coin launched (PositionManager):

event PoolCreated(
  bytes32 indexed _poolId,
  address _memecoin,
  address _memecoinTreasury,
  uint256 _tokenId,
  bool _currencyFlipped,
  uint256 _flaunchFee,
  FlaunchParams _params
);

_currencyFlipped tells you whether the memecoin is currency0 or currency1 in the pool key: when false, USDC is currency0; when true, they are swapped. Always honor it when interpreting amounts.

Every swap (PositionManager):

event PoolSwap(
  bytes32 indexed poolId,
  int256 flAmount0, int256 flAmount1, int256 flFee0, int256 flFee1,
  int256 ispAmount0, int256 ispAmount1, int256 ispFee0, int256 ispFee1,
  int256 uniAmount0, int256 uniAmount1, int256 uniFee0, int256 uniFee1
);

The three amount pairs are the fair launch, internal-swap-pool, and Uniswap legs of one swap; sum the pairs for the user-visible totals.

Price and liquidity updates (PositionManager):

event PoolStateUpdated(bytes32 indexed _poolId, uint160 _sqrtPriceX96, int24 _tick, uint24 _protocolFee, uint24 _swapFee, uint128 _liquidity);

Fair launch lifecycle (FairLaunch): FairLaunchCreated(bytes32 indexed _poolId, uint256 _tokens, uint256 _startsAt, uint256 _endsAt) and FairLaunchEnded(bytes32 indexed _poolId, uint256 _revenue, uint256 _supply, uint256 _endedAt).

Referrer earnings (ReferralEscrow): TokensAssigned(bytes32 indexed _poolId, address indexed _user, address indexed _token, uint256 _amount) when your share accrues, TokensClaimed(address indexed _user, address _recipient, address indexed _token, uint256 _amount) when you claim it.

Creator vaults (since block 24248448): PoolRegistered(bytes32 indexed _poolId, uint256 indexed _tokenId, uint24 _fee) on the HolderShareFeeCalculator when a coin launches with a vault (_fee in basis points, 150 to 500); Harvested(uint256 _received, uint256 _toHolders, uint256 _toCreators), CreatorClaimed(address indexed _recipient, uint256 _amount), Renounced() and TreasuryBoughtBackAndBurned(uint256 _spent, uint256 _burned) on each coin’s vault; DividendsDistributed(address indexed _sender, uint256 _amount) and DividendWithdrawn(address indexed _holder, uint256 _amount) on the coin itself. A coin’s vault is the owner of its Flaunch NFT; read memecoin() on it to confirm the pairing.

Holder pool payouts (UniversalRewardsDistributor): Claimed(address indexed account, address indexed reward, uint256 amount). See Verify the payouts.

If you would rather not run an indexer, the REST data API serves the same data.
