Overview

6Flow Studio is Tokenization Workflow Platform for CRE: a programmable, low-code orchestration layer for the Chainlink Runtime Environment (CRE).

Vision

next-gen IDE for Smart Contract Engineers in Financial Enterprise. It's like an n8n for CRE.

Architecture

Chainlink Usages

We built 6Flow on top of Chainlink Runtime Environment (CRE). Here are where we use CRE:

• Compiler outputs a full CRE project bundle (main.ts, workflow.yaml, project.yaml, secrets.yaml, config, package, tsconfig, .env) in compiler/src/codegen/mod.rs.
• Generated workflow code imports and uses CRE SDK from @chainlink/cre-sdk in compiler/src/codegen/imports.rs.
• Generated workflow structure follows CRE patterns (cre.handler, HTTPClient, EVMClient, runtime.getSecret, runtime.report, Runner.newRunner) in compiler/tests/snapshots/codegen_basic__branching_workflow_main_ts.snap.
• Generated package.json includes CRE dependency and setup (@chainlink/cre-sdk, bun x cre-setup) in compiler/src/codegen/files.rs.
• Generated workflow manifests are CRE-style artifacts (workflow.yaml, project.yaml, secrets.yaml) in compiler/src/codegen/files.rs.
• TUI runs local CRE simulation via CLI command cre workflow simulate ... in tools/tui/internal/tui/cre_cli.go.
• Frontend distributes compiled artifacts as *-cre-bundle.zip in frontend/src/lib/compiler/download-compiled-zip.ts.

In short: 6Flow is a visual builder that compiles workflows into native Chainlink CRE projects and executes/simulates them with the CRE toolchain.

Run Locally

While we encourage you to use 6flow.studio to build your workflow, you can also run it locally.

1. Setup Convex

2. Add in /frontend/.env:

   CONVEX_DEPLOYMENT=
   NEXT_PUBLIC_CONVEX_URL=
   NEXT_PUBLIC_CONVEX_SITE_URL=
   ETHER_SCAN_API_KEY=
   ALCHEMY_API_KEY=
   

3. Use separate terminals for each process.

Frontend (Next.js)

cd frontend
npm run dev

Convex

cd frontend
npx convex dev

TUI (main.go)

cd tools/tui
go run ./cmd/tui/main.go
