Jito-Solana
Jito-Solana is standing on the shoulders of giants — Solana Labs.
We've modified the Solana Labs validator client to allow validators to efficiently collect and distribute MEV to their stakers.
The validator client supports lists of transactions (bundles) which gives searchers and high frequency traders the flexibility in expressing transaction ordering. It tightly integrates with the relayer and third party block engines to improve the network performance for all.
Setting it up is as simple as downloading our validator client and passing the closest Block Engine URL on the command line.
Relayer
The relayer provides a layer of protection between your validator's transaction processing unit and spam from the network. The relayer works seamlessly with QUIC and allows one to separate receiving and verification of packets from the transaction processing inside your validator.
Run your own or use our hosted version.
Tip Payment & Distribution
The tip payment and distribution smart contracts are responsible for enabling and distributing validator tips.
Re-Staking / Vault
Jito (Re)staking is a multi-asset staking protocol for node consensus networks. The system is made of two programs: the restaking program and the vault program.
The restaking program acts as a node consensus network and operator registry. The program leverages a flexible system of admins so NCNs can customize the operators and vaults supported and operators can customize the NCNs they stake to and vaults they can receive delegations from.
The vault program manages the minting and burning of vault receipt tokens (VRTs). VRTs are SPL tokens that represent a pro-rata stake of assets in the vault. VRTs provide enhanced liquidity, composability, and interoperability with other Solana programs. The program also leverages a flexible system of admins so vaults can customize the capacity, operators that can receive delegations from the vault, the NCNs supported by the vault, and the fee structure for staking and unstaking.
Interceptor
Interceptor is a program designed to help SPL Stake Pool LSTs avoid the impacts of toxic decentralized exchange flow resulting from socialized liquidity.

Jito provides rewards in JTO on Solana, denominated in USD.
Blockchain/DLT
| Severity | Maximum | Minimum |
|---|---|---|
| Critical | $250,000 | $100,000 |
| High | $100,000 | $25,000 |
| Medium | $25,000 | $5,000 |
| Low | $5,000 | $1,000 |
Smart Contract
| Severity | Maximum | Minimum |
|---|---|---|
| Critical | $250,000 | $100,000 |
| High | $100,000 | $25,000 |
| Medium | $25,000 | $5,000 |
For critical Blockchain/DLT bugs, the reward amount is 10% of the funds directly affected, capped at the maximum critical reward $250,000. However, a minimum reward of USD $100,000 is to be rewarded in order to incentivize security researchers against withholding on a bug report.
For Critical Blockchain/DLT bugs with a non-funds-at risk impact, the reward will be paid out as follows:
For High Blockchain/DLT non-funds-at risk impacts, the reward will be paid out as follows:
For Critical Blockchain/DLT bugs, the reward is dependent on the ratio between the funds at risk, which includes all affected projects on top of the respective Blockchain/DLT, and the market cap according to the 7-day TWAP of JTO, calculated at the time the bug report is submitted.
For mainnet assets, the reward amount is 10% of the funds directly affected up to a maximum of $250,000. The minimum reward to discourage security researchers from withholding a bug report is $100,000.
Payouts are handled by the Jito Foundation directly and reward amounts are denominated in USD. However, payments are done in JTO on Solana.
The calculation of the net amount rewarded is based on the 7-day TWAP of JTO at the time of settlement. No adjustments are made based on liquidity availability.
The submission of KYC information is a requirement for payout processing.
Participants must adhere to the Eligibility Criteria. Employees and/or individuals closely associated with the members of other Solana client teams are also not eligible to participate in this bug bounty program.
Proof of concept is always required for all severities.
Category 3: Approval Required
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.
To ensure fairness and transparency in the bug reporting process, Jito is prohibited from claiming that a bug report is a known or duplicate issue without providing clear and verifiable evidence. This measure is crucial to maintaining the integrity of the bug bounty program. Jito must present specific proof that an issue has been previously reported and acknowledged even if not disclosed publicly or privately as a known issue. Without such evidence, the bug report will be considered valid and eligible for the appropriate reward as per the bug bounty program terms.
Jito Foundation's completed audit reports can be found at https://jito-foundation.gitbook.io/mev/resources/audits. Any unfixed vulnerabilities mentioned in these reports are not eligible for a reward.
By adhering to Immunefi's best practice recommendations, Jito has satisfied the requirements for the Immunefi Standard Badge.
