Nexus Mutual is an alternative crypto insurance provider running on the Ethereum blockchain. It was launched on May 30, 2019, with the main goal to offer protection from various risks for DeFi protocols. It is a legal foundation based in London, England. It enables members to share a critical risk directly with each other while all members’ funds are held in smart contracts run entirely on the public chain. Nexus Mutual is fully governed by its members, whose decisions are recorded and enforced by smart contracts on the Ethereum public blockchain.
On June 7, 2020, Nexus Mutual merged with Beyond Bank, as it did not have enough assets to keep up with the demand for smart-contract cover. Members with Nexus Mutual accounts were transferred over to the Beyond Bank Core Banking System.
Anyone can become a member of the Nexus platform by verifying the identity through the Know-Your-Customer (KYC) procedure, connecting the Ethereum wallet, and paying a nominal 0.002ETH fee. Being a member gives you the ability to buy, hold and swap NXM token (the native Nexus coin), buy and manage covers, participate in the network, and earn rewards. The Nexus Mutual platform is mobile compatible.
Soon after the Nexus’ launch, its first product, Smart Contract cover, was presented. It was developed to address security problems and protect funds from hacks. This product is designed to pay out claims when unintended code usage happens. It enables users to protect themselves against smart contracts bugs, thus preventing funds’ loss, while also allowing developers to deploy contracts with greater confidence.
The product is fully customizable, which means buyers can choose any smart contract verified by Etherscan, the cover amount in ETH that will be paid out, and coverage duration. The cover is priced in NXM, but the platform allows payment in ETH or DAI, which it exchanges for NXM. 90% of the cover price is burnt, and 10% is left for deposits to ensure an ongoing stake in the mutual. The surplus margin from Smart Contract Cover is about 30%.
Custody cover protects users who put funds into centralized exchanges and custodians. When a Smart Contract cover is purchased, the members' contributions flow into the Capital Pool, which improves the funding position of the mutual. The surplus generated from purchases is also added and then shared between all NXM holders.
Nexus Mutual reward system
The platform suggests different ways of getting rewards: by assessing claims, staking on projects, and voting in governance. Shield mining campaigns allow users to earn extra rewards every week by staking on projects sponsored by the community. They are available on the Rewards page. Participants can stake their deposits up to ten times in any projects they think are secure. Pending stakes are not appropriate for rewards.
Members can also receive bounties by becoming Nexus Mutual Claims Assessors. They need to stake NXM for at least 14 days to acquire verdict power and rewards, which are proportional to the stake. The participation in voting on governance proposals allows deciding the future of the protocol and earning additional NXM coins.
Nexus Mutual Token
NXM is the Nexus Mutual platform’s native utility token. NXM token is used to represent the membership rights and grant users the proportional power in the mutual.
NXM can only be purchased with ETH on the Nexus platform but its price varies. It rises when the Capital Pool, the amount of money the mutual holds, has sufficient funds and the insurance obligations are well-covered. When the mutual lacks funds, the price drops to encourage new investors to join. All funds raised from token purchases belong to members.
Only Nexus Mutual participants can buy, hold, and use NXM inside the Nexus Mutual platform. By purchasing NXM tokens users add liquidity (in ETH) to a shared pool of funds. Tokens can be used to purchase cover, vote for protocol modifications, and assess fair claims and risks. For risk assessment, members can stake NXM on a specific smart contract to show confidence in its security. If the cover is bought for that contract, the participants get rewards, but if the contract is deemed unsafe, the rate can be reduced. For claims assessment, members get rewards by staking NXM in support of a legal claim. 90% of NXM used to purchase cover is burned, and the remaining 10% is retained by the participants and can be used as a deposit when submitting claims. To lower the cover price NXM can be staked against any smart contract. When the cover is purchased the staker earns NXM. The consensus voting also earns NXM, while the non-consensus one blocks the stake for longer periods.
New tokens are minted as rewards for claims assessment making up about 3% of the cover price. Risk Assessment gives 20% of cover price minted in new NXM as a reward. Also, NXM token Custody cover service allows members to protect their funds in centralized custodians and exchanges.
NXM token can be wrapped to become freely transferable and tradable on decentralized exchanges or stored on Ethereum wallets. Wrapped NXM (WNXM) can be swapped against NXM with a 1:1 ratio. Only Nexus Mutual members who have completed their KYC procedures have the right to wrap or unwrap NXM tokens.
