Send Bundle

Introduction

This API is used to receive bundles, with the method name eth_sendBundle.

The block construction algorithm of BlockRazor Builder favors bundles that transfer more native tokens (BNB) to BlockRazor Builder EOA of which address is 0x1266C6bE60392A8Ff346E8d5ECCd3E69dD9c5F20 currently.

The gas price for transactions within the bundle must be at least the minimum standard required by BSC Validators (Currently at 1 gwei). For Tier 1 / Tier 2 users, 0 gwei transactions can be included in the bundle, but the average gasPrice of transactions(excluding those from the public mempool) which meets the demand of the Validator in the bundle must still be no less than 1 gwei.

Rate Limit

	Tier 3	Tier 2 / Tier 1
BPS	Unlimited	Unlimited
Maximum number of bundles accepted per block	Unlimited	Unlimited
0 gwei transaction in bundle	Not Supported	Supported

eth_sendBundle only implements auth restrictions for advanced features (such as 0 gwei transaction in bundle). If you need to use advanced features, please first set Authentication (auth token, which can be obtained on the console after registering BlockRazor) in the HTTPS request. The request example is as follows:

curl https://rpc.blockrazor.builders
    -X POST \json
    -H "Content-Type: application/json" \
    -H "Authorization: M2ZiZj……JhODA1" \
    -d '{
         "jsonrpc": "2.0",
         "id": "1", 
         "method": "", 
         "params": {
          }
        }'

minTimestamp	Optional	uint64	1710229370	Expected minimum Unix timestamp (in seconds) for the bundle to be valid
maxTimestamp	Optional	uint64	1710829390	Expected maximum Unix timestamp (in seconds) for the bundle to be valid
