Resolving a policy

Policy factories are listed in the order a resolver should try them. Ask each one whether an address is theirs until one says yes:

import { POLICY_FACTORIES } from "@0xslots/contracts";
 
for (const factory of POLICY_FACTORIES[chainId] ?? []) {
  if (await verify(factory, policyAddress)) {
    // genuine policy — read its terms and format them
  }
}

Factories predating IPolicyFactory are deliberately absent from that list. They have no verify(), so slots still pointing at their policies read as unrecognised — the honest answer rather than a guess.

ABIs

import {
  slotAbi,
  slotFactoryAbi,
  metadataModuleAbi,
  minimumTenurePolicyFactoryAbi,
} from "@0xslots/contracts";

Addresses are exported too, so you rarely need to hardcode one:

import { getSlotsHubAddress, POLICY_FACTORIES } from "@0xslots/contracts";
 
const factory = getSlotsHubAddress(8453);
