Fin-Core
Developer-first financial infrastructure

The operational core for transaction-driven products.

Fin-Core gives builders, operators, and evaluation teams a serious path from first integration to adoption-ready financial workflows.

Manual approvals, expiring activation links, and tenant-scoped onboarding keep the path credible from demo to production hardening.
Financial infrastructure for builders

Build operationally credible financial products faster.

Fin-Core is the developer-first operational core for teams building wallets, ledgers, transaction orchestration, and regulated-style financial workflows. It gives you a serious platform to integrate, evaluate, and grow on top of.

What Fin-Core is

Infrastructure for teams that need product-facing financial capabilities, approval-aware onboarding, and integration paths that feel credible with both builders and stakeholders.

Who it is for
  • Infrastructure for builders and operators, not just a demo surface.
  • Tenant-aware services, approval-led onboarding, and serious integration controls.
  • Built for hackathons, pilots, and future production hardening.
Start in 3 steps

Get access, run one command, see your transaction.

The first five minutes should prove the loop: activation creates credentials, the CLI creates a transaction, and the console shows what happened.

1. Get access

Request access, open your activation link, and reveal the development API key when you are ready to store it.

2. Run this command

Install the CLI with npm, then run `fincore demo` from PowerShell, Terminal, or any Node-ready shell.

3. See your transaction

Open `/console/transactions` from the dashboard link printed by the CLI and inspect the request, response, and metadata.

Run your first real transaction

Execute on local Anvil without wallet setup.

Run the demo, then submit a real local deposit. Open the dashboard to see your transaction.

What Fin-Core is

A product and infrastructure layer for transaction-driven systems.

Fin-Core is designed for teams building real financial software, not just pitching a concept. It sits between product ambition and operational reality.

Operational core

Fin-Core gives teams a hardened control layer for transaction flows, approvals, tenant boundaries, and product-facing financial operations.

Real integration surface

Use SDKs, APIs, and structured onboarding to move from evaluation to working implementation without inventing the operating model yourself.

Adoption-ready path

Start in a workshop or pilot, then keep the same platform concepts as your product matures toward stricter controls and broader rollout.

Who it is for

Built for teams that need serious financial building blocks.

Whether you are shipping a prototype, validating a pilot, or evaluating infrastructure, Fin-Core meets technical and operational users where they are.

Developers and hackathon builders

Ship credible prototypes quickly with clear onboarding, smoke-test paths, and infrastructure that already speaks in product and operator terms.

Startups and technical founders

Stand up wallets, ledgers, treasury logic, or transaction orchestration without building every operational surface from scratch.

Institutions and operators

Evaluate whether the platform can support serious product workflows, integrations, and governed client activation before deeper adoption.

Developer path

See the integration shape early.

The first developer path is short on purpose: get approved, activate, verify health, then expand into your own product flow.

TypeScript SDK starting point
import { FinCoreClient } from "@fincore/sdk";

const client = new FinCoreClient({
  baseUrl: process.env.FINCORE_BASE_URL!,
  apiKey: process.env.FINCORE_API_KEY!,
});

await client.health.get();
await client.bootstrap.get();
await client.usage.getSummary();
What you can build with it

Use Fin-Core as the foundation for financial products and internal operations tooling.

Why teams choose it

Credibility, clarity, and product-minded infrastructure.

The difference is not only what Fin-Core exposes technically. It is also how the platform frames onboarding, security, and operator trust from the start.

Clear trust model

Manual approvals, expiring activation links, and controlled credential reveal make the hosted path feel official from the first touchpoint.

Developer-ready interfaces

SDK, CLI, docs, and first-request flows are shaped for people who want to build immediately without losing operational context.

Tenant-scoped execution

Isolation, predictable request handling, and operational guardrails help teams build on top of a platform that behaves consistently.

Serious messaging

Fin-Core positions itself as infrastructure for product teams, operators, and evaluators who care about credibility, not empty hype.

How onboarding works

A trustworthy activation flow for real product evaluation.

Fin-Core keeps onboarding human-reviewed and activation time-bound so the path feels deliberate, secure, and ready for responsible evaluation.

Step 01
Request access

Submit your project, team context, and expected operating profile through the hosted onboarding form.

Step 02
Review and approval

Fin-Core reviews the request for fit, readiness, and integration expectations before activation is issued.

Step 03
Activate securely

Approved teams receive an expiring activation link that reveals development credentials only when the user is ready.

Step 04
Run the developer path

Store credentials, run smoke checks, and move into docs, usage views, and integration work with the same product context.

Call to action

Start with the infrastructure path you can actually grow on.

Use Fin-Core to validate product direction, run a serious pilot, or give your developers a cleaner path into financial operations infrastructure.
