Bridge Relayer Slashing Executor (Misbehavior)

WHAT IT DOES

Bridge Relayer Slashing Executor (Misbehavior) enables users to submit evidence of bridge relayer misbehavior and execute slashing penalties against malicious or faulty relayers. The tool reads the bridge contract state to verify relayer registration, bond amounts, active status, and misbehavior history. Users can submit evidence of misbehavior types such as double-signing, invalid message delivery, data tampering, or timeout/liveness failures. The tool then executes the slashing transaction, confiscating the relayer's bond and reducing their delegation rewards. Batch slashing is supported for multiple relayers.

This tool is essential for bridge security participants, validators, and DAO members who want to enforce accountability in cross-chain messaging systems. It provides a mechanism to penalize misbehaving relayers, protecting the bridge from malicious or negligent operators.

HOW TO USE

1. Connect your EVM wallet to the network where the bridge is deployed.

2. Enter the bridge contract address and select the misbehavior type.

3. Add relayers by entering their address and an evidence hash (proof of misbehavior) per line.

4. Click "Check Relayer Status" to verify registration, bond, and misbehavior history for each relayer.

5. Review the relayer status table showing active status, bond amount, and misbehavior count.

6. Click "Execute Slashing" to submit the evidence and execute slashing penalties.

7. Track progress via the status bar and confirmation of the transaction hash upon completion.

TECHNICAL MECHANISM

The tool reads the bridge contract using view functions: getRelayerStatus(address) for registration and bond info, getMisbehaviorCount(address) for the number of prior offenses, and getSlashingConditions() for the applicable penalties. For execution, the tool attempts batch slashing via slashBatch(relayers[], evidenceHashes[], misbehaviorType) when available, falling back to sequential slashRelayer(relayer, evidenceHash, misbehaviorType) calls. The misbehavior type is encoded as a uint8: 0 for double-signing, 1 for invalid message, 2 for data tampering, 3 for timeout. Gas estimation applies a 20% buffer, and actual gas costs are calculated from receipt.effectiveGasPrice.

WHAT IT CANNOT SEE

This tool cannot verify the accuracy of off-chain evidence submitted for slashing—it relies on the user to provide valid evidence. It cannot guarantee that the slashing will be executed if the evidence is insufficient or if the bridge contract rejects the evidence. It cannot recover funds if the slashing is incorrectly applied, either due to false evidence or contract bugs. It cannot account for false-positive misbehavior reports that may target innocent relayers. It cannot manage slashing across different bridge protocols with different evidence formats or slashing mechanics; each bridge may have unique requirements. It cannot prove malicious intent versus technical error; the tool executes slashing based on submitted evidence, which may be ambiguous.

PLEASE NOTE

EVM chains only. This tool requires that the bridge contract implements the slashing interface. Not all bridges support slashing—verify that the contract includes slashing functions. Submitting false evidence can have serious consequences; ensure you have valid proof before executing slashing. The tool does not provide legal advice; slashing decisions should be made carefully.
