Interactive Playground

Test pools, quotes, premium preview, and referral flow snippets with @layercover/sdk

Use this playground to test discovery and pricing with the SDK in read-only mode (no wallet connection required).

This page is intentionally read-only. It does not execute purchases. Use the copyable purchase snippet in your product UI where users connect their own wallet.

What You Can Test

Initialize LayerCoverSDK.create(...) with a public RPC provider
Discover pools and fetch active quotes
Preview premium calculations for amount + duration
Attach a referral code for partner attribution
Copy a production purchase snippet for your embedded flow

SDK Playground (Read-Only)

No login required

RPC URL

Mode: read-only discovery and quote preview (API proxied via this docs server)

Upstream API: https://app.layercover.com

Status: Initialize read-only SDK to begin (no wallet needed).

Pool

Loaded quotes: 0

Quotes

Load a pool to view quotes.

Purchase Inputs

Amount (USDC)Duration (weeks)Referral Code (optional)

Referral not set

Purchase execution is intentionally disabled in this docs playground. Use the copied snippet in your app where users connect their own wallet.

Code Snippets (Copy/Paste)

Initialize Read-Only SDK

import { JsonRpcProvider } from 'ethers';
import { LayerCoverSDK } from '@layercover/sdk';

const provider = new JsonRpcProvider('https://sepolia.base.org');

const sdk = await LayerCoverSDK.create(provider, {
  apiBaseUrl: 'https://app.layercover.com',
});

const pools = await sdk.listPools();

Load Active Quotes

const poolId = 1;
const quotes = await sdk.getActiveQuotes(poolId);
const bestQuote = quotes[0] ?? null;

if (!bestQuote) {
  throw new Error('No active quotes for this pool');
}

Preview Premium

import { parseUnits, formatUnits } from 'ethers';

const amount = parseUnits('1000', 6);
const weeks = 4;
const durationSeconds = weeks * 7 * 24 * 60 * 60;

const premium = sdk.calculatePremium(
  amount,
  500,
  durationSeconds
);

console.log('Premium:', formatUnits(premium, 6), 'USDC');

Purchase Flow (Embed In Your App)

import { encodeBytes32String, parseUnits } from 'ethers';

function normalizeReferralCode(value) {
  if (!value) return undefined;
  if (/^0x[a-fA-F0-9]{64}$/.test(value)) return value.toLowerCase();
  return encodeBytes32String(value);
}

const poolId = 1;
const amount = parseUnits('1000', 6);
const weeks = 4;
const maxRateBps = 500;
const referralInput = '';
const referralCode = normalizeReferralCode(referralInput);

const result = await sdk.purchase(poolId, amount, weeks, maxRateBps, referralCode);
console.log('tx:', result.txHash, 'policy:', result.policyId);

Recommended Setup

Use a Base Sepolia RPC URL (default: https://sepolia.base.org)
Select a pool with active quotes for realistic results
Ensure your docs app can reach https://app.layercover.com from server-side proxy routes
