Relays can merge bundles and suggest them for profit switching. Miners can define a list of trusted relay addresses from which megabundles are accepted.
Scoring function does not change between v0.3 and v0.4:
- v0.3 - v0.4
: bundle score used to sort bundles.
: ordered list of transactions in a bundle.
: set of transactions in the mempool.
: gas used by transaction .
: gas price of transaction .
: fee cap per gas of transaction .
: priority fee per gas of transaction .
: effective fee per gas of transaction equal (, BASEFEE + ).
: miner fee per gas of transaction equal - BASEFEE.
: coinbase difference from direct payment.

Flashbots mainnet relay switching to alpha-v0.4
- Miners asked to upgrade to v1.10.8-mev0.4.0
- Miners can update 100% of capacity to this new version
- Miners will need to upgrade to the newest version of mev-proxy or whitelist the RPC call
eth_sendMegabundlefor your specific environment.
- Miners must add a new command line parameter for Megabundle Relays (see below)
Miners must configure a new command line parameter to specify which relays megabundles will be accepted. The parameter is set as follows for a list of 3 relayers.
The default Mega Bundle Relayer is set to the Flashbots Relayer
0x870e2734DdBe2Fba9864f33f3420d59Bc641f2be. If you only want to receive bundles from this default relayer no configuration is necessary. For configurations which allow more relayers, be sure to also include the Flashbots relayer in your configuration.
