Program Overview

BT.Finance is a multi-chain smart DeFi yield aggregator that targets the best and sustainable yield for tokens.

The Vaults are divided into 3 pools as Stable Profits Pool, High Yield Pool, and Smart Hybrid Pool to all users with various risk tolerances. The BT Vault V1 is to earn $CRV $SUSHI $PICKLE $BAS from other excellent DeFi yield aggregators and platforms, thanks for their innovative products and hard work. BT Vault V2 will develop smart hybrid strategies and launch it on BSC, Heco and other chains.

The bug bounty program covers all its smart contracts and the prevention of loss of user funds.

Rewards by Threat Level

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System. This is a simplified 5-level scale, with separate scales for websites/apps and smart contracts/blockchains, encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit.

Payouts are handled by the BT Finance team directly and are denominated in USD. Payouts are done in USDC or BT.

This bug bounty program has a maximum amount of USD 100 000 for all bug/vulnerability findings. Because of this, if there are valid bug reports covering different vulnerabilities submitted where the total reward amount is greater than the remaining bounty pool amount, the appropriate reward levels will be provided on a first-come-first-served basis, and the total bounty pool will be used to reward reports on this priority system until exhausted. This amount will be updated as rewards are paid out and rewards will adjust accordingly.
