# Unified blockchain API for business

## The cost of building it yourself

Every blockchain network has its own protocol, data format, and operational rules. Supporting multiple chains means maintaining a separate integration for each one - with dedicated engineering time for node operations, chain upgrades, data normalization, and edge cases like reorganizations and confirmation delays.

For most teams, this infrastructure work consumes more time than the product features their customers actually need.

| Challenge | What it looks like | What it costs |
|  --- | --- | --- |
| Adding a new chain | Weeks of development, new node infrastructure, testing | Engineering time diverted from product |
| Monitoring deposits | Custom indexer per chain, confirmation tracking, reorg handling | Missed transactions erode user trust |
| Generating wallets | BIP-32/44 implementation, key management, security audits | Cryptographic complexity and liability |
| Tracking balances | Separate queries per chain, format normalization | Slow, inconsistent portfolio views |
| Receiving alerts | Building event infrastructure per network | Delayed responses to on-chain activity |
| Handling reorganizations | Custom detection and rollback logic per chain | Data inconsistencies and accounting errors |


Bottom line
Vilna handles this infrastructure layer so your team can focus on product instead.

## One API, three capabilities

Most blockchain API providers focus on a single problem - node access, data indexing, or custody. Vilna combines the three capabilities that crypto businesses need most into a single platform:

### Monitor addresses and receive events

Register any address on any supported chain and receive notifications when activity occurs - deposits, withdrawals, token transfers, confirmations. Events are delivered with at-least-once guarantees, not best-effort webhook retries.

Guaranteed delivery
Every on-chain event reaches your system. No silent failures, no missed transactions.

### Manage wallets at scale

Generate unique deposit addresses for every customer using HD wallet derivation. The master key stays with you - Vilna never touches private keys. Create thousands of addresses across multiple chains without managing cryptographic infrastructure.

### Track payments automatically

Create payment invoices, monitor incoming transactions in real time, and handle partial payments and overpayments automatically. Customers see a payment page with QR code and live confirmation progress.

## How Vilna fits into your stack

```

Your application talks to one API with one authentication model. Vilna handles everything chain-specific - node protocols, data formats, confirmation rules, reorganization handling - and returns normalized, consistent data regardless of the blockchain.

When Vilna adds support for a new network, it becomes available to your product automatically. No code changes, no new SDKs, no migration.

## Built for companies that serve customers

Unlike developer tools designed for individual projects, Vilna is built for platforms that manage many accounts:

- **Workspace and project isolation.** Each of your customers operates in a dedicated project with isolated data and consistent performance. No cross-tenant data leakage, no noisy-neighbor effects.
- **Granular access control.** Three API key types with scoped permissions per resource. Your team members and systems get exactly the access level they need.
- **Programmatic management.** Create workspaces, manage teams, provision API keys, and organize projects through a dedicated [Management API](/apis/mgmt/) - everything your operations team needs to scale.


Multi-tenancy, role-based access, and project isolation are not afterthoughts bolted onto a developer tool. They are built into the data model from day one.

## Supported blockchains

Vilna supports EVM chains (Ethereum, BSC, Polygon, Arbitrum, Base, and others), Bitcoin-family networks, Solana, TRON, TON, Cosmos, and more. New chains are added regularly - your integration supports them without code changes.

See the [full list of supported chains](/overview#supported-blockchains).

## Fast integration by design

Most blockchain API integrations take weeks because developers spend time reading documentation, figuring out endpoint structures, and debugging parameter mismatches. Vilna cuts this down in two ways:

- **AI-assisted development.** Vilna provides an [MCP server](/guides/mcp) that connects directly to your AI coding assistant (Claude, Cursor, and other MCP-compatible tools). The assistant gets full access to every API endpoint, parameter, and response schema - so it can generate correct integration code without your developers switching between IDE and documentation.
- **Consistent API surface.** Every chain uses the same endpoints, the same authentication, and the same data format. A developer who integrates one chain already knows how to work with all of them.


Result
Your team reaches a working integration in days, not weeks.

## Who uses Vilna

- **Crypto exchanges** need deposit detection, address generation, and balance sweeping across dozens of chains. See the [exchange pattern](/business/use-cases#automated-deposit-detection-for-exchanges).
- **Payment processors** accept crypto with invoice tracking, QR codes, and automatic partial payment handling. See the [payment pattern](/business/use-cases#multi-network-payment-processing).
- **Wallet providers** build multi-chain wallet products with HD derivation and real-time balance monitoring. See the [wallet pattern](/business/use-cases#scalable-wallet-infrastructure-for-crypto-banking).
- **Corporate treasury teams** monitor company wallets, get movement alerts, and simulate transactions before sending. See the [treasury pattern](/business/use-cases#cross-chain-treasury-management).
