Bundle Cancellations

Eden now 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.

Understanding bundle cancellations​

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,
      minTimestamp,
      maxTimestamp,
      revertingTxHashes,
      replacementUuid, // UUIDv4 to uniquely identify submission
    }
  ]
}

Replacing bundles​

To replace a bundle, send the new bundle via eth_sendBundle with the same replacementUuid as the bundle you want to replace.

Canceling bundles​

Canceling a bundle will prevent Eden builders from including it on-chain. To cancel a bundle, call the eth_cancelBundle endpoint, or use the cancelBundle function in your preferred Flashbots library.

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