Program Overview

The Eco Currency is intended to serve as a decentralized alternative to fiat currencies. Other cryptocurrencies either fix their monetary policies and admit exchange rate volatility, or attempt to limit volatility and achieve dollar parity through various policies.

Eco does not treat dollar-parity as a proxy for utility. Eco is a free-floating currency designed to achieve its aims through monetary policy transparently established and managed by a representative group of governing “Trustees” who are elected by the community of Eco holders. Trustees have one core mandate: to maximize the wealth held in ECO. As with many other token systems, Eco currency holders are also empowered to vote on community proposals and protocol upgrades.

Eco features two tokens: the variable supply base currency (ECO), and a deflationary supply token (ECOx) intended to incentivize long-term holders and bootstrap an open market signaling expectations for ECO adoption. These tokens, together with the various contracts and components that support them, form the Eco Currency Protocol.

This bug bounty covers the following core components and peripherals:

  • The core Eco Protocol contracts
  • The ECO NFT and ECO Claim contracts
  • All associated dApp
    • ECO ID dApp
    • ECO claim dApp

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. All Smart Contract bug reports require a PoC to be eligible for a reward. Explanations and statements are not accepted as PoC and code is required.

Critical smart contract vulnerabilities are capped at 10% of economic damage, primarily taking into consideration funds at risk, but also PR and branding aspects, at the discretion of the team. However, there is a minimum reward of USD 50 000, unless the bug falls under the “Direct theft of any user funds, whether at-rest or in-motion, other than unclaimed yield or fees/refunds” category, in which case the 10% cap still applies.

High smart contract vulnerabilities are capped at 100% of economic damage, primarily taking into consideration funds at risk, but also PR and branding aspects, at the discretion of the team. However, there is a minimum reward of USD 10 000.

Critical website and application bug reports will be rewarded with USD 100 000 only if the impact leads to a direct loss in funds or a manipulation of the votes or the voting result. All other impacts that would be classified as Critical would be rewarded USD 50 000

The following vulnerabilities are not eligible for a reward:

The Eco Association requires an affidavit that the bug bounty hunter is not from a sanctioned county or a sanctioned entity. The collection of this information will be done by the Eco Association.

Payouts are handled by the Eco Association directly and are denominated in USD. However, payouts are done in USDC.

Assets in scope

All smart contracts of Eco can be found at https://github.com/helix-foundation/currency. All the web/app of Eco can be found at https://github.com/helix-foundation/eco-id-app and https://github.com/helix-foundation/eco-claim-dapp. However, only those in the Assets in Scope table are considered as in-scope of the bug bounty program.

Though only the proxy contracts are listed as in-scope, current implementation and any further updates to the implementation contracts are considered in scope. When reporting a bug, please make sure to select the relevant proxy smart contract as the target.

If an impact can be caused to any other asset managed by Eco 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 only applies to Critical and High impacts.
