SDK Quickstart

This is the shortest path for generating an Anyware proof bundle with anyware-prover.

Install

pnpm add anyware-prover viem

Create a client

import { AnywareClient } from "anyware-prover";

const client = new AnywareClient({
  network: "sepolia-base-sepolia",
});

You can also pass explicit endpoints instead of a named preset:

const client = new AnywareClient({
  ethRpcUrl: process.env.ETH_RPC_URL!,
  beaconApiUrl: process.env.BEACON_API_URL!,
  destinationRpcUrl: process.env.BASE_RPC_URL!,
});

Check your endpoints

Before generating live proofs, run a preflight check:

const report = await client.preflight();

if (!report.overallOk) {
  throw new Error("Anyware endpoints are not ready.");
}

CLI equivalent:

anyware-prover doctor --network sepolia-base-sepolia

Prove a vault lock

The simplest happy path in this repo is a vault lock stored as mapping(address => uint256).

const bundle = await client.proveVaultLock({
  vault: "0xVaultAddress",
  borrower: "0xBorrowerAddress",
});

You can then serialize it for transport:

const envelope = client.toBundleEnvelope(bundle);
console.log(envelope.bundleVersion);
console.log(envelope.bundle.slotKey);

Prove a known storage slot

If you already know the exact slot key:

const bundle = await client.proveStorageSlot({
  account: "0xTargetContract",
  slot: "0xKnownStorageSlot",
});

Prove a mapping value

If you know the mapping slot index and the key address:

const bundle = await client.proveMappingValue({
  account: "0xTargetContract",
  keyAddress: "0xUser",
  mappingSlot: 0n,
});

What you get back

The SDK returns a ProofBundle that includes:

• beacon header fields
• execution payload header fields
• SSZ proof from beacon body to execution payload header
• account proof
• storage proof

That bundle is ready to hand to the Solidity verifier on the destination chain.

Next step

Once you can generate a bundle, move to the Solidity quickstart to verify it onchain.
