Symbiosis
Symbiosis is a cross-chain engine and interchain communication Protocol. Our know-how — any to any token swaps regardless of the blockchain networks, both EVM and non-EVM supported.
PoC required
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 Critical severity 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. In addition, all Critical severity bug reports must also come with a suggestion for a fix to be considered for a reward.
All known issues previously highlighted in the following audit reports are considered out of scope:
Payouts are handled by the Symbiosis team directly and are denominated in USD. However, payouts are done in USDT(ERC20), USDT(BEP20), USDC(ERC20) or USDC(Polygon), at the discretion of the bug report submitter.
Program Overview
Symbiosis is a cross-chain engine and interchain communication Protocol. Our know-how — any to any token swaps regardless of the blockchain networks, both EVM and non-EVM supported.
Besides, Symbiosis has presented an inter-blockchain messaging protocol, i.e. can be used to integrate with AAVE, Cream, and virtually any DeFi protocol. A use-case: instant liquidity provision with any token the user has at her hands.
For seamless integration with third party devs / projects, we have Symbiosis API and SDK.

KYC not required
No KYC information is required for payout processing.
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)
- Any denial of service attacks that are executed against project assets
- 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.
