ABI

Every ABI below is emitted straight from the compiler by foci/backend/ops/scripts/emit-ui-docs.ts, so it matches the deployed bytecode on arc-mainnet (chain 5042). Each file is the bare ABI array — exactly what viem, ethers, wagmi and cast expect.

Everything at once#

foci.json — every contract with its address, the chain id, the factory's start block and the third-party addresses (Uniswap, Permit2, USDC) you need alongside them. One download is enough to build a client.

bash

curl -O https://foci.family/abi/foci.json

import foci from "./foci.json";

const factory = foci.contracts.find((c) => c.name === "FociLaunchFactory")!;
await client.readContract({
  address: factory.address as `0x${string}`,
  abi: factory.abi,
  functionName: "launchFee",
});

Note

FociBondingCurve and FociLauncherToken are deployed once per launch, so they have no fixed address. Read the pair from the factory with getLaunchedToken(token) — see Addresses.

Using one file#

bash

curl -O https://foci.family/abi/FociLaunchFactory.json

import factoryAbi from "./FociLaunchFactory.json";

The JSON is the array itself, not an object wrapping one, so it drops straight into abi: with no unwrapping.
