Bundle Cancellations

Eden supports replacing and cancelling bundles by passing a standard UUIDv4 identifier as an optional parameter with your bundles. To use this feature send your bundles to the same RPC endpoint used for normal bundles: https://api.edennetwork.io/v1/bundle using this parameter as described below.

Unique Identifier for Bundles

Bundles can be replaced and canceled using a unique identifier (replacementUuid) assigned to a bundle at the time of submission.

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "eth_sendBundle",
  "params": [
    {
      txs,
      blockNumber,
      replacementUuid, // UUIDv4 to uniquely identify submission
    }
  ]
}

Replace a Bundle

Submit your new replacement bundle with the same replacementUuid value in order to replace a bundle.

• Use the same method eth_sendBundle.
• Use the same value for replacementUuid as the original bundle you wish to replace.

Your original bundle MUST have been sent with a replacementUuid specified.

Cancel a Bundles

Call the method eth_cancelBundle in order to cancel a bundle. Or use the cancelBundle function in your preferred Flashbots library.

Your bundle MUST have been sent with a replacementUuid specified.

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "eth_cancelBundle",
  "params": [
    {
      replacementUuid, // UUIDv4 to uniquely identify submission
    }
  ]
}
