 ## Project Overview
 
-**What**: Rust execution client for Berachain using Reth SDK  
-**Status**: In development, not production ready  
+**What**: Rust execution client for Berachain using Reth SDK (git tag `v2.4.0` across all reth-* deps; reth node crates are not on crates.io)  
+**Status**: Production (runs Berachain mainnet)  
+**Toolchain**: MSRV 1.95, edition 2024; `make pr` uses nightly for fmt/clippy  
 **Architecture**: Standard Ethereum execution with Berachain-specific chain configuration  
-**Key Difference**: Prague1 hardfork activated at genesis (time: 0) for 1 gwei minimum base fee
+**Key Differences**: Berachain fork ladder (Prague1–4, Osaka1), PoL system transaction (type 0x7E), custom header with `prevProposerPubkey`, 1 gwei minimum base fee from genesis
