Threshold Network
Threshold Network powers tBTC, the Bitcoin standard in finance and the most decentralized 1:1 tokenized BTC, enabling Bitcoin liquidity to flow seamlessly across chains without compromising on settlement finality. Built on threshold cryptography and secured by a rotating network of independent node operators, tBTC distributes control of BTC so that no single entity can act unilaterally on funds. This architecture embodies Bitcoin’s core values : trust-minimized, permissionless, and censorship-resistant, while maintaining a direct settlement path back to native Bitcoin. By bridging BTC into DeFi through a system designed to favor math over trust, tBTC establishes the foundation for secure, decentralized Bitcoin utility across multiple ecosystems. This infrastructure enables tBTC to power lending, trading, and yield across major DeFi networks.

- Server-side non-confidential information disclosure, such as IPs, server names, and most stack traces
- Impacts causing only the enumeration or confirmation of the existence of users or tenants
- Impacts caused by vulnerabilities requiring un-prompted, in-app user actions that are not part of the normal app workflows
- Lack of SSL/TLS best practices
- Impacts that only require DDoS
- UX and UI impacts that do not materially disrupt use of the platform

All categories
- Impacts requiring attacks that the reporter has already exploited themselves, leading to damage
- Impacts caused by attacks requiring access to leaked keys/credentials
- Impacts caused by attacks requiring access to privileged addresses (including, but not limited to: governance and strategist contracts) without additional modifications to the privileges attributed
- Impacts relying on attacks involving the depegging of an external stablecoin where the attacker does not directly cause the depegging due to a bug in code
- Mentions of secrets, access tokens, API keys, private keys, etc. in Github will be considered out of scope without proof that they are in-use in production
