Since the signature fields are stripped, the parsing of the transaction fails silently in Alloy. To address this, the extension dynamically adds these fields during deserialization, enabling a pending MEV Blocker transaction to be deserialized into an `alloy_rpc_types_eth::Transaction`.\n\n\n# Why not fix this in Alloy?\nIt is hard to tell who is right here. Alloy has a valid point to require all fields for a valid transaction. For some clients with less strict typing, the parsing of the transaction works. This does not require any workaround and for that reason, the API of MEV Blocker is for many people easy to use. For Alloy, it is not possible to parse the transaction without the signature fields.\n\n# Usage\nSee `subscribe_mev_blocker.rs` in [examples](./examples) for a full usage examples. \n\nExample usage:\n```rust\nlet ws_client = WsConnect::new(MEV_BLOCKER_SEARCHERS_URL);\nlet provider = ProviderBuilder::new().on_ws(ws_client).await?;\n\nlet subscription = provider.subscribe_mev_blocker_pending_transactions().await?;\n```\n\n# Acknowledgements\nMany thanks to the [CoW DAO](https://cow.fi/) to provide such an API. And many thanks to the [alloy-rs](https://github.com/alloy-rs) team.\n\n# License\nThis project is licensed under the [Apache 2.0](./LICENSE-APACHE) or [MIT](./LICENSE-MIT).","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcakevm%2Falloy-mev-blocker-client","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcakevm%2Falloy-mev-blocker-client","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcakevm%2Falloy-mev-blocker-client/lists"}
