Developers — building on exchange8

The single-repo story​

Clone any exchange8 service and build — the platform SDK and the exchange8 SDK arrive as pinned git dependencies; committed .sqlx caches mean no live database is needed to compile:

git clone https://github.com/Exchange8-dev/exchange8-me.git
cd exchange8-me
cargo build
cargo test     # offline

The vertical lifecycle​

make infra-up        # platform TLS-only PG 18 + Valkey
sentin8-cli db bootstrap
vertical init        # creates the exchange8 database + per-service schemas
vertical enroll      # registers services, scopes, admin UIs, triggers
make start           # captain spawns the fleet

No migration code exists — greenfield: schema changes rewrite the init SQL and re-run vertical init.

Integration surface​

  • Rust: the exchange8-sdk shared plane (FIX/OUCH/ITCH codecs, Price-Qty math, event contracts) — see the SDK page
  • FIX/OUCH members: connect sessions through Exchange8:Gateway
  • App/API clients: BFF-proxied REST/WebSocket order shapes
  • Events: the venue flow over Sentin8:Bus

Deep dive​

Every service's full docs live in its reference section — harvested from the public repositories at build time.
