Program Overview
Belong is building the world’s first performance-based affiliate network for physical businesses, combining real-world experiences with on-chain technology to transform how venues, promoters, and customers interact. Through its flagship product, Belong CheckIn, venues pay only for verified customer visits and spending, ensuring marketing efforts directly translate to measurable outcomes. The platform rewards promoters with visit bounties and a share of customer spend, all tracked transparently on-chain and paid instantly in LONG tokens. With a seamless Web2.5 approach, Belong eliminates the need for crypto wallets, making blockchain participation accessible to everyone. Beyond CheckIn, the Belong ecosystem enables tokenized venues and events, AI-driven community engagement, location-verified rewards, and on-chain bounty programs that bridge digital and physical interactions. Available on Web, iOS, and Android, Belong is redefining how physical spaces connect with digital communities through trust, transparency, and automation.

Prohibited Activities
- Any testing on mainnet or public testnet deployed code; all testing should be done on local-forks of either public testnet or mainnet
- Any testing with pricing oracles or third-party smart contracts
- Attempting phishing or other social engineering attacks against our employees and/or customers
- Any testing with third-party systems and applications (e.g. browser extensions) as well as websites (e.g. SSO providers, advertising networks)

- Automated testing of services that generates significant amounts of traffic
- Public disclosure of an unpatched vulnerability in an embargoed bounty
- Any other actions prohibited by the Immunefi Rules
Feasibility Limitations
The project may be receiving reports that are valid (the bug and attack vector are real) and cite assets and impacts that are in scope, but there may be obstacles or barriers to executing the attack in the real world. In other words, there is a question about how feasible the attack really is. Conversely, there may also be mitigation measures that projects can take to prevent the impact of the bug, which are not feasible or would require unconventional action and hence, should not be used as reasons for downgrading a bug's severity.
Therefore, Immunefi has developed a set of feasibility limitation standards which by default states what security researchers, as well as projects, can or cannot cite when reviewing a bug report.
