Addresses

Everything below is Arc testnet, chain 5042002. 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.

Per-launch contracts have no fixed address#

Two of the contracts in the reference are deployed once per launch by the factory:

• FociV2BondingCurve
• FociV2LauncherToken

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.
