Axis SDK

Convenience library for interacting with the Axis protocol.

Quickstart

This library expects react, wagmi, viem and @tanstack/react-query as peer dependencies.

pnpm add @axis-finance/sdk react wagmi viem @tanstack/react-query wagmi

Initialize the SDK

import { createSdk } from "@axis-finance/sdk";

const sdk = createSdk();

Wrap your app with <QueryClientProvider> (if not already)

TanStack Query doesn't know how to serialize bigint queryKeys. Wagmi hashFn serializes bigints for us.

import { hashFn } from "wagmi/query";
import { QueryClient, QueryClientProvider } from "@tanstack/react-query";

const queryClient = new QueryClient({
  defaultOptions: {
    queries: {
      queryKeyHashFn: hashFn,
    },
  },
});

export const App = () => (
  <QueryClientProvider client={queryClient}>
    <>{/* ... */}</>
  </QueryClientProvider>
);

Wrap your app with <WagmiProvider>(if not already)

import { createConfig, WagmiProvider, http } from "wagmi";
import { mantle } from "wagmi/chains";
import { hashFn } from "wagmi/query";
import { QueryClient, QueryClientProvider } from "@tanstack/react-query";

const config = createConfig({
  chains: [mantle],
  transports: { [mantle.id]: http() },
});

const queryClient = new QueryClient({
  defaultOptions: {
    queries: {
      queryKeyHashFn: hashFn,
    },
  },
});

export const App = () => (
  <QueryClientProvider client={queryClient}>
    <WagmiProvider config={config}>
      <>{/* ... */}</>
    </WagmiProvider>
  </QueryClientProvider>
);

Wrap your app with <OriginSdkProvider>

import { createSdk } from "@axis-finance/sdk";
import { OriginSdkProvider } from "@axis-finance/sdk/react";
import { QueryClient, QueryClientProvider } from "@tanstack/react-query";
import { createConfig, WagmiProvider, http } from "wagmi";
import { mantle } from "wagmi/chains";
import { hashFn } from "wagmi/query";

const sdk = createSdk();

const config = createConfig({
  chains: [mantle],
  transports: { [mantle.id]: http() },
});

const queryClient = new QueryClient({
  defaultOptions: {
    queries: {
      queryKeyHashFn: hashFn,
    },
  },
});

export const App = () => (
  <QueryClientProvider client={queryClient}>
    <WagmiProvider config={config}>
      <OriginSdkProvider sdk={sdk}>
        <>{/* ... */}</>
      </OriginSdkProvider>
    </WagmiProvider>
  </QueryClientProvider>
);

Use the SDK

Queries

Queries return the standard @tanstack/react-query useQuery() result type.

import { useLaunchQuery } from "@axis-finance/sdk/react";

export const Launch = () => {
  const {
    data: launch,
    status,
    error,
  } = useLaunchQuery({ chainId: 5000, lotId: 1 });

  if (status === "pending") {
    return <div>Loading launch data...</div>;
  }

  if (status === "error") {
    return <div>Error resolving launch: {error?.message}</div>;
  }

  return (
    <div>
      <h1>{launch.info.name}</h1>
      <p>{launch.info.description}</p>
    </div>
  );
};

Contract calls

Contract calls return a common interface for Axis contract interactions.

import { useBid } from "@axis-finance/sdk/react";

export const Bid = () => {
  import { useBid } from "@axis-finance/sdk/react";
  import type { BidParams } from "@axis-finance/sdk";
  import { formatUnits } from "viem";

  const bidParams: BidParams = {
    chainId: 5000,
    lotId: 1,
    amountIn: 10000000000000000000n,
    amountOut: 20000000000000000000n,
    bidderAddress: "0x123...",
    referrerAddress: "0x456...",
  };

  const { submit, simulation, transaction, receipt, isWaiting, error } =
    useBid(bidParams);

  return (
    <div>
      {isWaiting && <div>Confirming bid transaction...</div>}
      {error && <div>Transaction error: {error.message}</div>}
      You're spending {formatUnits(bidParams.amountIn, 18)}
      <button disabled={isWaiting} onClick={submit}>
        Bid
      </button>
    </div>
  );
};

For Axis protocol integrators

By default, the SDK has default services for the following:

• Cloak: Service for encrypting bids offchain
• Metadata: Service for storing launch metadata offchain (e.g. name, description, image URLs...)
• Subgraph: Service for querying launch graph data (combines onchain data with offchain data)

You can override these services by passing in your own URLs in the SDK config:

import { createSdk } from "@axis-finance/sdk";

export const sdk = createSdk({
  cloak: {
    url: "https://cloak.example.com/api",
  },
  metadata: {
    url: "https://metadata.example.com/api",
  },
  subgraph: {
    1: {
      url: "https://mainnet-subgraph.example.com/api",
    },
    81457: {
      url: "https://blast-subgraph.example.com/api",
    },
  },
});
