Reduce Your Exposure to Crypto Market Risks
Decentralized Parametric Insurance

Neptune Mutual Protocol offers a couple of different flavors of decentralized parametric insurances.

Dedicated Covers

Created by projects, for their communities. These are tailor made cover policies designed to protect a specific community from security risk.

Diversified Covers

Created to enable liquidity providers to diversify the risk of their capital across a portfolio of projects. This enables the Neptune Mutual marketplace to offer cover policies to a wider variety of projects in DeFi, CeFi and Metaverse.

Let's #buidl

Don't let your users ever leave your DeFi app. With a few lines of code, enable your users to access all cover features. Supply liquidity, purchase covers, and interact with your decentralized cover pool directly within your own DeFi app, frontend, or backend.

  import { ChainId, liquidity } from '@neptunemutual/sdk'

  const add = async () => {
    const amount = 150_000 * 1e18

    // First approve the Policy contract to spend your DAI
    await liquidity.approve(ChainId.Ethereum, key, { amount })

    const response = await liquidity.add(ChainId.Ethereum, key, amount)

  [info] {
    status: 'Success',
    result: {
      nonce: 1,
      gasPrice: BigNumber { _hex: '0x06fc23ac00', _isBigNumber: true },
      wait: [Function (anonymous)]
