deBridge Bug Bounty Program

Details

deBridge is a cross-chain interoperability and liquidity transfer protocol that allows decentralized transfer of data and assets between various blockchains. The deBridge protocol is an infrastructure platform and hooking service for:

• cross-chain composability of smart contracts
• cross-chain swaps
• bridging of any arbitrary asset and data
• interoperability and bridging of NFTs

deBridge bug bounty program is focused on preventing:

• Loss of user funds locked (principal) by freezing or theft
• Loss of governance funds
• Theft of unclaimed assets
• Permanent freezing of unclaimed assets
• Smart contract fails to deliver promised returns
• Unauthorized minting of wrapped assets that will lead them to lose peg

Registration

The registration procedure is straightforward. Bug bounty hunters must first register on Immunefi’s platform in order to be eligible for bounties. They can then submit their bug reports to Immunefi along with the necessary logs and data to receive the reward. Submissions should include the documents and coding needed to reproduce the vulnerabilities, as well as pointers for bug fixes.

Bug Reporting

Participants should be aware that only the first person to report a bug will be eligible for the appropriate reward. They must submit all relevant links, documents, and codes along with the vulnerabilities. For each vulnerability, only one form will be accepted for submission. Bounty hunters, on the other hand, are free to submit multiple forms for multiple vulnerabilities.

Any attempt to publicly disclose the vulnerability before resolving it will result in the reward being canceled. deBridge and Immunefi reserve the right to disqualify anyone who does not follow the bounty program’s rules and regulations. Finally, deBridge will never negotiate for payment under any threat or coercion. 

Rewards

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 and smart contracts/blockchains, encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit.

In addition to Immunefi’s Vulnerability Severity Classification System, deBridge classifies the following vulnerabilities as follows. In case of discrepancy, the one below will be followed.

Critical

More than 5% of the loss of TVL or an unauthorized minting of deAssets in an amount that leads to substantial loss of the peg of the wrapped asset (Total supply of deAsset exceeds amount of underlying collateral locked for more than 5%)

High

Up to 5% of the loss of TVL or an unauthorized minting of deAssets in an amount that leads to substantial loss of the peg of the wrapped asset (Total supply of deAsset is on up to 5% exceeds the amount of underlying collateral locked)

Rewards by Threat Level

1. Critical: USD $200,000 and unique deBridge NFT
2. High: USD $40,000
3. Medium: USD $5,000

The following vulnerabilities/problems are not eligible for a reward:

• Default bridging functionality doesn’t support non-standard assets (e.g. rebase assets, assets with elastic supply or tokens with fees during transfer)
• If a user sets an incorrect receiver or fallback address he won’t be able to claim his transfer in the destination chain and funds might be locked forever
• If user passes ​​REVERT_IF_EXTERNAL_FAIL flag and specifies "data" and "receiver address" params that will lead to tx being constantly reverted
• Framework used by the deBridge node exploitation of which requires knowledge of IP address unless information about IP address was obtained during the attack
• Problem with the callProxy smart contract when gas limit specified by claimer is not enough for the proper execution of the externalCall that leads to externalCall being reverted even though transaction itself is completed

Payouts are handled by the deBridge team directly and are denominated in USD. However, payouts are done in USDT and USDC, with the choice of the ratio at the discretion of the team.
