Program Overview

Lido on Polkadot is a liquid staking solution for DOT. Lido lets users earn DOT staking rewards without needing to maintain infrastructure and enables them to trade staked positions, as well as participate in on-chain decentralized finance with their staked assets. Lido on Polkadot gives you:

  • Liquidity through tokenization — no activation delays and the ability to sell your staked tokens or use them in decentralized finance;
  • One-click staking — no complicated steps;
  • Decentralized security and maximized staking performance — assets spread across the best performing validators from the whole network, that are not predefined. That is possible because of an algorithm based on provable data and decentralized oracles. You can learn more here.

Rewards by Threat Level

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.2. This is a simplified 5-level scale, with separate scales for websites/apps, smart contracts, and blockchains/DLTs, focusing on the impact of the vulnerability reported.

All web/app bug reports must come with a PoC with an end-effect impacting an asset-in-scope in order to be considered for a reward. Explanations and statements are not accepted as PoC and code is required.

Smart Contracts Rewards Breakdowns

Assets in scope

All smart contracts of Lido on Polkadot can be found at https://github.com/mixbytes/lido-dot-ksm. However, only those in the Assets in Scope table are considered as in-scope of the bug bounty program.

If an impact can be caused to any other asset managed by Lido on Polkadot that isn’t on this table but for which the impact is in the Impacts in Scope section below, you are encouraged to submit it for the consideration by the project. This applies to only Critical and High impacts.
