0.15.0

@0xslots/sdk

Type-safe SDK for the 0xSlots protocol — contract reads and writes over viem, with ERC-20 approval handled for you. Full reference: docs.0xslots.org.

Install

pnpm add @0xslots/sdk @0xslots/contracts viem

Usage

import { SlotsClient } from "@0xslots/sdk";
import { slotFactoryAddress } from "@0xslots/contracts";

const client = new SlotsClient({
  publicClient,                                  // viem PublicClient
  walletClient,                                  // viem WalletClient, for writes
  factoryAddress: slotFactoryAddress[chainId],   // only createSlot / collectAll need it
});

const state = await client.slotState(slot);      // one SlotLens.getSlotInfo call

// `account` is who becomes occupant — it need not be the signer.
await client.buy({
  slot,
  account,
  selfAssessedPrice: 5_000_000n,
  depositAmount: 1_000_000n,
});

await client.topUp(slot, 500_000n);
await client.release(slot);
await client.collect(slot);

SlotsClient reads the chain, not the indexer. The indexer endpoints are exported as DEFAULT_API_URL, LOCAL_API_URL, API_URLS and apiUrlFor(env) for querying it directly — see Indexer.

Surface

buy sends the quote it just read as maxPayment, so it pays what it was quoted or reverts; pass maxPayment: 0n to disable the ceiling on purpose. Call simulateBuy first to surface a module's refusal with its own error.

Terms are proposed by presence, and land at the next buy after a one-day delay:

import { NO_MODULE, TERMS } from "@0xslots/sdk";

await client.proposeTerms(slot, { taxRateBps: 200 });
await client.proposeTerms(slot, { moduleTerms: { module, settings } });
await client.proposeTerms(slot, { moduleTerms: NO_MODULE }); // remove the module
await client.cancelTerms(slot, TERMS.MODULE);

CollectionsClient (slot-bound NFT collections) and CollectivesClient (SlotCollective governance, roles in COLLECTIVE_ROLES) ship beside it.

React

import { useSlotAction, useSlotsClient } from "@0xslots/sdk/react";

Requires wagmi, viem and @tanstack/react-query as peer dependencies. useSlotsClient({ factoryAddress?, offerBookAddress?, chainId? }) memoizes a client from wagmi's clients; useSlotAction wraps every write with shared pending and receipt state. useCollectivesClient does the same for collectives.
