Repos

This document describes how the Seismic repos are organized.

Stack Overview

Repositories

Repo	Upstream Fork	What It Does
summit	— (original)	Consensus client (Simplex protocol via Commonware)
seismic-reth	paradigmxyz/reth	Full execution client with TEE, encrypted RPC, genesis builder
seismic-foundry	foundry-rs/foundry	sforge/sanvil/scast dev tools
seismic-solidity	ethereum/solidity	Compiler: adds suint, sbool, saddress shielded types
seismic-revm	bluealloy/revm	Mercury EVM: CLOAD/CSTORE, 6 precompiles, flagged storage
seismic-evm	alloy-rs/evm	Seismic block execution layer
seismic-alloy	— (original)	Rust SDK: TxSeismic type, encryption-aware providers
seismic-alloy-core	alloy-rs/core	Shielded types (suint, sbool, saddress), FlaggedStorage primitive
seismic-trie	alloy-rs/trie	Merkle trie encoding for FlaggedStorage values
seismic-enclave	— (original)	ECDH + AES-GCM crypto for tx encryption/decryption
seismic-revm-inspectors	paradigmxyz/revm-inspectors	EVM tracing/debugging with Seismic support
seismic-compilers	foundry-rs/compilers	Compiler integration for sforge
seismic-foundry-fork-db	foundry-rs/foundry-fork-db	Fork DB with FlaggedStorage support
seismic-client	— (original)	TypeScript client (Viem actions + Wagmi hooks)

Fork Management

Every forked repo has:

• A seismic branch as the default branch containing all Seismic modifications

• main/master tracking the upstream original project

• Periodic rebases or merges from upstream to stay current

To see what Seismic has changed in any repo, compare the seismic branch against the upstream base:

https://github.com/SeismicSystems/seismic-reth/compare/main...seismic
https://github.com/SeismicSystems/seismic-revm/compare/main...seismic
https://github.com/SeismicSystems/seismic-foundry/compare/master...seismic

Dependency Flow

Changes flow bottom-up through the stack. A change in a lower layer may require updates in everything above it:

alloy-core change → may require trie, revm, alloy, evm, reth, foundry updates
revm change       → may require evm, reth, foundry updates
alloy change      → may require evm, reth, foundry updates
reth change       → usually isolated

All repos use [patch.crates-io] sections in Cargo.toml to pin specific commits of their dependencies. When updating a dependency, you need to:

1. Make the change in the upstream repo (e.g., seismic-revm)

2. Push and note the commit hash

3. Update the [patch] section in downstream repos (e.g., seismic-reth, seismic-foundry)
