The latter always goes against the intention of the sender and can be consider as a robbery in secret towards sender.\n\nThe project supports senders to capture MEV under the ERC-4337 framework:\n\n- Senders use special ERC-4337 wallets called `MEVBoostAccount` and send special userOps called `BoostUserOp` which invokes boost methods of `MEVBoostAccount`.\n- Searchers use a special ERC-4337 paymaster called `MEVBoostPaymaster` which refunds maxium MEV to senders by `BoostUserOp` auction and also pays transaction fee for `BoostUserOp`.\n\nThe project mainly has following advantages:\n\n- Improve the current MEV ecosystem and maximize the sender's interests by trustlessly ensuring the maxium MEV capture by the sender.\n- It provides a completely **decentralized** and **permisionless** MEV-Share solution.\n- Considering the existence of MEV, the project promotes the adoption of the ERC-4337 wallet by providing the build-in mev capture features and making transaction cost possibly less expensive than the EOA.\n\n## Value Redirection\n\n### Current MEV Ecosystem\n\n- In the view of the sender\n  - `sender` --[fee to excute tx]--> `validator`\n- The fact goes against the intention of the sender\n  - `sender` --[fee to excute tx]--> `validator`\n  - `sender` --[mev caputured by searcher]--> `searcher`\n  - `searcher` --[share mev with validator]--> `validator`\n\n### MEV Ecosystem with MEVBoostAA\n\nMEVBoostAA captures MEV from searchers to senders based on the framework of ERC-4337. so, senders will be protected.\n\n- `sender` --[mev caputured by searcher]--> `searcher`\n- **`searcher` (as a paymaster) --[fee to excute tx] --> `validator`**\n- **`searcher` --[maxium MEV refund]--> `sender`**\n- `searcher` -- share mev with validator --> `validator`\n\n## SDK\n- [sdk for account](https://github.com/doublespending/mev-boost-aa-account-sdk)\n- [sdk for searcher](https://github.com/doublespending/mev-boost-aa-searcher-sdk)\n\n## Work Flow\n\n![image info](https://github.com/doublespending/MEVBoostAA/raw/main/graphs/interaction.png)\n\nThe sender just need to depoly a ERC-4337 wallet `MEVBoostAccount`, construct a `BoostUserOp` (i.e. a userOp calling the `boostExecute` or `boostExecuteBatch` method) and broadcast it to the ERC-4337 mempool.\n\nThe first parameter of the method `boostExecute` or `boostExecuteBatch` is `MEVConfig` which including `minAmount`(i.e. minium required mev amount) and `selfSponsoredAfter`(i.e. timestamp after which the `BoostUserOp` is executed without `searcher` and `MEVBoostPaymaster`).\n\nSearchers who have deposited fund to `MEVBoostPaymaster` will grab `BoostUserOps` in the ERC-4337 mempool.\n\n- If the `BoostUserOp` is profitable, the searcher will fill `paymasterAndData` to make `BoostUserOp` valid, build a profitable ERC-4337 bundle including that `BoostUserOp` and send it to the bundler. Finally, if `BoostUserOp` is success, the sender will get `minAmount` MEV value from searcher and the `BoostUserOp` is sponsored by the searcher.\n\n- If the `BoostUserOp` is not profitable, the searcher will not fill `paymasterAndData` of the `BoostUserOp`. That `BoostUserOp` in the ERC-4337 mempool will be valid after timestamp `selfSponsoredAfter`. The bundler will regularly bundle and execute that `BoostUserOp`.\n\nBriefly, a `BoostUserOp` is valid when one of the following conditions is met:\n\n- The searcher fills the `paymasterAndData`, pays `minAmount` MEV value to the sender and sponsors that `BoostUserOp`.\n- The `BoostUserOp` is valid after timestamp `selfSponsoredAfter` and sponsored by the sender.", "lastUpdated": 0, "projectGithub": "MEVBoostAA", "projectTwitter": "0xbbbb_eth"}, "recipient": "0xBBbb17A8C1Ce64be28faCd93b22450abB01B5DCA"}}
