Exchange & DEX API Integration
Production integration of one or more trading venues into a client-owned application, with normalized data models, secure credentials and reliable recovery.
Priced for your scope. A short description is enough to start.
What's included
- Venue API and authentication integration
- Market-data and order normalization
- Rate-limit and reconnect handling
- Order-state reconciliation
- Tests, documentation and deployment
Best fit for
- Trading applications
- Portfolio and execution platforms
- Multi-venue dashboards
More than connecting an SDK
Exchange integrations fail at boundaries: partial fills, sequence gaps, expired signatures, duplicate retries and inconsistent instrument identifiers. We build an adapter around those conditions so the rest of the product consumes a stable internal interface.
Supported scope can include Solana DEX routing, Hyperliquid, Polymarket, EVM protocols or centralized exchange APIs, subject to the venue's terms and the client's account permissions.
Delivery and operational boundaries
TierZero provides software engineering, testing, documentation and deployment support. The client controls its infrastructure, accounts, credentials, wallets and product decisions. We do not custody client or end-user assets, transmit funds on a client's behalf, operate customer trading accounts, recommend specific investments or guarantee financial results. Production use remains subject to the client's legal, compliance and risk review.
Technical scope
What we design and verify
A production exchange & dex api integration is more than a working demo. Each major component below is scoped around the target network or platform, expected load, failure conditions and the way your team will operate it after handover.
Venue API and authentication integration
The integration is built around rate limits, timeouts, retries and measurable latency. Where appropriate, fallback providers and health checks are included in the architecture.
Market-data and order normalization
Submission and execution logic includes simulation, configurable limits, explicit failure states and structured logs. Production credentials and signing authority remain separated from application logic.
Rate-limit and reconnect handling
Controls are enforced in code before an action is submitted. Thresholds remain configurable, while rejected actions and triggered safeguards are recorded for later review.
Order-state reconciliation
Submission and execution logic includes simulation, configurable limits, explicit failure states and structured logs. Production credentials and signing authority remain separated from application logic.
Tests, documentation and deployment
The component is verified against agreed scenarios and edge cases. Assumptions, privileged operations and known limitations are documented for the client team.
Definition of done
Before delivery, we validate the agreed happy path, expected failures and operational controls. You receive the applicable source code, configuration reference, deployment instructions and a walkthrough of the system. Any third-party fees, infrastructure subscriptions or external dependencies are identified during scoping.
Delivery
How the engagement works
Technical discovery
We confirm the objective, constraints, integrations and acceptance criteria.
Architecture & scope
You receive milestones, responsibilities, timeline and the final quote.
Build & verification
Implementation is tested against the agreed scenarios with visible progress.
Handover & support
We deploy or hand over the code, documentation and operating instructions.
Built for production
Scope, security and ownership
Delivery model
Application, data and infrastructure components are scoped as independently testable services with clear interfaces.
Security baseline
Secrets, authentication, observability, backups and deployment access are handled with least-privilege defaults.
What we need from you
User flows, integrations, traffic expectations, hosting constraints and existing code or infrastructure.
Questions before you start
How is Exchange & DEX API Integration priced?+
We quote each project after discussing the required features, integrations and deployment. Send a short description; a finished specification is not required. We agree the scope, milestones and price before work begins.
How long does delivery take?+
Timing depends on integrations, testing depth and whether existing code is involved. After a short technical discovery, we provide milestones and a delivery estimate before payment.
Who controls the source code, infrastructure and keys?+
The agreed source code and deployment are handed over to the client. Production wallets, seed phrases and private keys remain client-controlled; we design integrations around scoped credentials and least-privilege access.
How do we verify the result?+
We agree measurable acceptance criteria before implementation, then provide testing evidence, documentation and a handover walkthrough for the delivered scope.
Can you work with our existing code or infrastructure?+
Yes. We can begin with a focused review, identify reusable components and propose the smallest safe implementation path instead of forcing a full rebuild.
