⛓️ spring-boot × web3

Ship web3 / defi on Spring Boot with sensible defaults.

Spring Boot is a Java workable choice for web3 / defi. GreatCTO auto-detects both — adds the web3 archetype overlay, wires web3-specific gates, and runs 34 specialist agents around your existing Spring Boot workflow.

What changes when GreatCTO joins your Spring Boot project

Detection → overlay → gates → reviewers.

1 · DETECT

Stack + archetype

GreatCTO reads your pom.xml / build.gradle and detects spring-boot + web3 archetype from signals: imports, file structure, env vars, README hints.

2 · OVERLAY

Archetype pack

Attaches the web3 archetype overlay: oracle review, MEV protection, upgradeability (UUPS/Diamond/Beacon) decision, multisig. Override if your specifics differ; the defaults are sensible for Spring Boot-style projects.

3 · GATES

Spring Boot-aware reviewers

qa-engineer runs ./gradlew check / SpotBugs / JaCoCo coverage; security-officer scans for deserialization sinks + Spring SpEL injection; performance-engineer profiles JVM + GC patterns.

4 · MEMORY

Cross-project lessons

Bugs you've hit before in other Spring Boot projects (connection-pool exhaustion, ORM N+1 queries, retry storms) — the agent's Step 0 includes the prior detection order. MTTR drops 94 % on second occurrence (methodology).

First 10 minutes

Concrete walkthrough.

$ cd my-spring-boot-app && npx great-cto init
✓ scanning manifests… found manifest
✓ stack: spring-boot (Java)
✓ archetype: web3
⚠ archetype + stack combo is unusual — review overlay manually
✓ 34 agents ready

$ /start "add multisig vault deposit handler"
▸ architect drafting ARCH-web3.md…
▸ pm decomposing into beads tasks…
⚐ gate:plan — your approval needed

Approve → 3 senior-devs run in parallel worktrees → 5 reviewers fan out in parallel → gate:ship → deploy. One real run walked stage-by-stage: /proof.

⚠ Honest caveat

Spring Boot (Java) is not a typical fit for web3 / defi. The archetype overlay still attaches, but you may want to override defaults more aggressively. Check the web3 archetype page for the typical stack list and decide if your case is the right tool / right archetype.

Architecture

Every step of the pipeline, transparent.

No black-box "AI does it all" loop. GreatCTO is a deterministic state machine — 8 stages, 22 nodes, 2 human gates. Every node maps to a real agent on GitHub. Inspect the state machine →
