@strike-options/sdk

Typed TypeScript client for Strike: weekly options vaults (covered calls and cash-secured puts) on Robinhood Chain stock tokens, paid in USDG, run by mandate-bound AI agents. Built on viem. Unaudited, testnet only.

It reads vaults, series, quotes, agents and risk; dry-runs proposals against a vault's mandate with the contract's own previewProposal; and sends deposits, buys, proposals, settlements and agent registration (v2 and v3, including v3's EIP-712 signer consent). The deployed addresses for Robinhood Chain testnet (46630) and Arbitrum Sepolia (421614) are built in.

Inside the Strike repository this package is the workspace package @strike/sdk; on npm it is @strike-options/sdk.

Install

npm install @strike-options/sdk viem

Node 22 or later, ESM only.

Read a vault and a quote (no wallet)

import { createStrikeClient, formatUsdg, formatWad, getStrikeChain } from "@strike-options/sdk";
import { createPublicClient, http } from "viem";

const publicClient = createPublicClient({ chain: getStrikeChain(46630), transport: http() });
const strike = createStrikeClient({ publicClient, chainId: 46630 }); // Robinhood Chain testnet, read-only

const vault = await strike.getVault("0xADFF7900dbe01E8170a750AB88e1f4eA8D9D1D4e"); // TSLA covered call
console.log(vault.symbol, vault.kind, vault.epoch.state, vault.mandate); // sTSLA-CC covered-call Selling {...}
if (vault.series) {
  const quote = await strike.quoteBuy(vault.series.id, 10n ** 18n); // one option
  console.log(`strike $${formatWad(vault.series.strike, 2)}: ${formatUsdg(quote.premium)} USDG per option`);
}

Reads need only a publicClient. Pass a viem walletClient too and the client can write: every write simulates first (a revert surfaces as a decoded custom error such as MarketClosed), approves tokens when needed, sends, and waits for the receipt.

More

• listVaults(), getVault(), getSeries(), quoteBuy(), previewProposeByDelta(), seriesRisk(), agentStats(), claimables()
• deposit, buy, redeemOptions, proposeByDelta, settle, registerAgent, setSigner, postBond, createVault
• Pricing helpers (blackScholes, strikeForDelta, vaultCapacity), mandate checks (mandateProblems, explainMandateReason), settlement-hint discovery, decision-record anchoring (verifyDecisionAnchor) and every contract ABI
• deploymentsFor(chainId) lists every deployment of a chain (v2 and v3 on 46630); createStrikeClient({ deployment }) targets one
• auditMirror({ chainId, symbol? }): the price mirror audit. Every round of the testnet MirrorFeeds is checked against Robinhood Chain mainnet Chainlink (the mainnet round with the same updatedAt must carry the same answer, across proxy phases), with each push's transaction, the deploy-time seed listed apart and the largest gap between pushes; auditSettlement({ chainId, vault }) checks the round each series settled at (or will settle at) and whether it is mainnet's first print after expiry. Read-only, no key; node scripts/verify-mirror.mjs in the repository prints it
• rpcTransportFor(chainId): a viem transport over Alchemy when ALCHEMY_API_KEY is set (the key in a header, never in a URL), then STRIKE_RPC_URL, then the chain's public RPC, falling back down the list; rpcUrlFor(chainId) gives one URL for tools such as cast (print it only through redactRpcUrl)
