SecureRPC has now started accepting bundles from external parties. These are not bundles for OpenMEV, rather these are external searchers sending bundles through our base RPC infrastructure (SecureRPC is what this is called). Submitting transactions through this does not get processed through OpenMEV arbitrage logic: it gets sent to multiple aggregated downstream endpoints including Eden Network, Flashbots, Ethermine, etc.
Improvements to the OpenMEV integration are pending approval for Sushiswap: see github.com/sushiswap/sushiswap-interface/pull/719
New SDK that is completely re-written in a functional-style approach is being planned see preliminary outline at github.com/manifoldfinance/libmev
This next release includes the following breaking changes.
OpenMEV Integration for Sushiswap will be changed going forward to 'Sushi Guard'. OpenMEV continues to be the underlying platform for this. Protocol integrations are encouraged to brand the solution to make it relevant and consistent with their branding identity.
eth_sendPrivateTransactionis slated for the next release of SecureRPC/OpenMEV
eth_sendMevBlockis slated for the next release of OpenMEV
Transaction States are now classified under the following scheme - UNCHECKED -> Tx status has not been checked and there's no information about it. - PROCESSING -> Tx checks are in place until a resolution happens: OK, INDETERMINATE, ERROR. - OK -> Relay received the Tx && all downstream miners accepted without complains && tx mined successfully - INDETERMINATE -> Relay received correctly the Tx && at least one miner accepted the TX && TX potentially mineable - ERROR -> Relay haven't received the TX || none of the miners accepted the Tx || Tx was not mined successfully see more at githubgithub.com/manifoldfinance/libmev/blob/master/src/SecureRpc/OpenMevState.ts
Bug fixes and improvements
Fair amount of sandwiches made it on-chain over the weekend
We are hitting nonce collisions for multiple bundles per block (good problem)
Multi DEX arbitrage are now being submitted. We are investigating if they were all relayed as there seems to be no signed bundle topic
Filling now and the new relayed_v2 topic now passing our simulator.
You can track the account now at this address etherscan.io/address/0x4F680254517617C175e223b37C8e40c473623647
NOTE: This does not yet utilize the new OpenMEV Router contract, we expect testing this weekend to start in earnest
NOTE: Addresses will be changing soon, we will maintain the list of addresses through our new ChainLog service which is being tested now on Goerli test network. ee github.com/manifoldfinance/dslog
ETH2 Staking Service
- Finalized ETH2 Network Topology
attnetsattribute is a property of SSZ ENR
This crawls the devp2p layer, until it finds a node with
attnets attribute. This indicates that it found a node which is alive and there is an
attnets attribute in its
ENR. In addition, we record the value of the
attnets attribute. The value of the
attnets attribute is a bitvector showing what subnet the node is subscribed to. We look for a the distribution of numbers of nodes to
attnets they are subscribed to, to get the number of nodes subscribed to the subnet as % of all alive nodes as recorded in scanning. This in essence provides us with the intersection of most reliable Eth2 Validators for connectivity.
FOLD Staking v2
- EIP-4626: Tokenized Vault Standard is moved to Final in the Ethereum Improvement Proposal process. This means its now recognized as a standard. This standard is key as it will enable trading of your staked position/hedging of lent assets.
- GitHub Statics Overview can now be found on the main page for our organization. Below is an example.
