Addresses

Everything below is Arc mainnet, chain 5042. The live table on this page is read from the API at request time, so it reflects what is actually deployed rather than what was true when this page was written.

Arc testnet (chain 5042002) still carries an older deployment. None of its addresses are listed here, and they are not interchangeable with the mainnet ones.

Per-launch contracts have no fixed address#

Three of the contracts in the reference are deployed once per launch:

• FociBondingCurve — by the factory
• FociLauncherToken — by the factory
• FociRewardsDistributor — by the rewards factory, only for launches that chose Fees go to: Holders; read it with rewardsFactory.distributorOf(token) (zero otherwise)

There is no address to configure. Read them from the launch record:

const launch = await client.readContract({
  address: FACTORY, abi: factoryAbi, functionName: "getLaunchedToken", args: [token],
});
launch.curve;   // the bonding curve for this launch
launch.exists;  // false for an unknown token — check this first

getLaunchedToken returns a zeroed struct rather than reverting for an address it does not know, so an unchecked read makes an unknown token look like a live curve at phase 0.

Indexing#

FACTORY_START_BLOCK is the block of the deploy broadcast — there is nothing to index before it.

Note that the public Arc RPC and a dedicated provider disagree on eth_getLogs limits: the public node allows a 25,000-block span, QuickNode caps it at 10,000. Pin your range to your provider, and re-measure it if you switch — a range above the cap fails every request rather than degrading.
