Auctioneer

The top-of-block is valuable in a financial environment because it provides an execution guarantee. Flame uses a trusted top-of-block sequencing rule to designate a trusted operator to conduct a sealed-bid, first-price auction for top-of-block execution, and submit the result for sequencing. The sequencing rule ensures the signed auction result is executed first, provided it is included in the block and signed by the trusted auctioneer.

Auctioneer RPC URL: https://tob.flame.dawn-1.astria.org

Flame’s Auctioneer runs a first price auction for a bundle, restricted to a slot.

Bundles/bids submitted to the Auctioneer are simulated against the latest block to calculate the bid paid to the Auctioneer.

TIP

The current version of the trusted auctioneer supports eth_sendTransaction for submission. Bids are calculated from the tip paid by the transaction as follows:

totalFee = tx.Gas * min(tx.GasTipCap, tx.GasFeeCap - tx.baseFee)

To submit a bid to the auction using cast, set up your env vars:

export ETH_RPC_URL=https://tob.flame.dawn-1.astria.org
export DEST_ADDR=<destination-address>
export PRIV_KEY=<your-private-key>
export BID=<your-bid-value>

Submit your bid:

cast send $DEST_ADDR \
    --value 10000000000000000000 \
    --gas-price $BID \
    --private-key $PRIV_KEY

Bid Submission Demo

Bids are submitted to the auctioneer using the eth_sendTransaction JSON RPC method. See the tool below, which provides an example for a bot that receives an optimistic block, waits a given amount of time, and submits a bid to the auction.
