Glo is a fully backed stablecoin pegged to the US dollar. We're non-profit. Like other stablecoin companies, we earn interest from our reserves. The difference: we give all of it away to reduce extreme poverty. You can generate basic income for people in extreme poverty simply by owning Glo. More Glo adoption means more basic income for more people.

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 High and Critical Smart Contract 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.
Glo requires KYC to be done for all bug bounty hunters submitting a report and wanting a reward. The information needed are name, address, date and full amount you claim, clearly stated on an invoice. The collection of this information will be done by the project team.
Payouts are handled by the Glo team directly and are denominated in USD. However, payouts are done in USDC.
- USD $50,000
- USD $2,500
- USD $1,250
- USD $1,000
Assets in scope
- Smart Contract - ERC1967Proxy for USDGLO on EthereumType
- Smart Contract - current implementation contract of USDGLO on EthereumType
- Smart Contract - ERC1967Proxy for USDGLO on PolygonType

All smart contracts versions of Glo can be found at https://gitlab.com/global-income-coin/usdglo. 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 Global Income Coin 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 impacts.
