Avici: Building Internet Finance with Zerion API

What Is Avici?

Avici is an internet-native finance application: think Revolut, but self-custodial and built on-chain. Available globally and live with the majority of its users across the US, Europe, and the Middle East. The premise is dead simple: if you have the internet, you have access to a self-custodial banking solution.

Avici Business: Your Company's Financial Stack, Rebuilt

Individual accounts are just the beginning. @Avicibiz brings Avici's self-custodial infrastructure to companies, and it's built for the way modern businesses actually operate.

Think Mercury + Ramp + Slash, but built from the ground up for global-native businesses.

Here's what's on the table:

• Self-custodial business wallets: company treasury without counterparty risk. Your funds never sit in someone else's hands.
• Named USD/EUR pass-through accounts: virtual bank accounts tied to your business identity, not a fintech intermediary's.
• Visa business cards: corporate spending, globally, without legacy overhead or approval queues.
• Multiple yield options: stop letting your idle treasury balances collect dust. Put it to work, onchain.
• Seamless on/off-ramps: fiat in, stablecoins out, payroll sent, vendors paid. All self-custodial.
• Collateral / Secured loans: Deposit crypto collateral and borrow money(USDC) against it.
• Unsecured / Non-collateralised loans  (Upcoming): Based on the Trust score, borrow money from anywhere across the world for your business. 
• Others (Upcoming): Invoices, Payroll integrations, collections and payouts etc., 

Whether you're a DAO managing a multi-sig treasury, a remote-first startup paying contractors across multiple countries, or a cross-border e-commerce brand tired of losing 3% on every international transfer or a global native start-up or a freelancer: Avici Business replaces the all the fintech tools you're currently duct-taping together.

The challenge: Onchain data for neobank-like UX

When you're building something that should look like a neobank, users expect to see two things: what they hold and what they've done. Positions and transaction history aren't nice-to-haves, they're table stakes.

For Avici, the challenge was surfacing this onchain data reliably without dealing with Solana RPCs and custom indexing infrastructure. A small team focused on shipping products doesn't have the bandwidth to do blockchain plumbing. Every hour spent on data is an hour not spent on the card experience, the virtual accounts, or features on the roadmap.

Avici needed a way to pull wallet positions and full transaction history through a single API without stitching together multiple providers.

The solution: Zerion API's positions and transactions endpoints

Avici integrated Zerion API to power two core parts of the user experience: portfolio positions and transaction history.

With the positions endpoint, Avici displays each user's tokens and stablecoin balances in real time. Instead of raw amounts, users see their holdings with proper metadata and prices. It’s the kind of clarity a financial product demands.

The transactions endpoint handles the other half: a complete, interpreted, human-readable history of every onchain action. For a product that looks like a neobank, having an accurate transaction trail matters for user trust and operational transparency.

The integration meant Avici could skip the months of work it would take to build and maintain this infrastructure in-house. One API surface, normalized data, no extra vendors.

"Zerion API took a big piece of infrastructure off our plate. Instead of building indexers and stitching together data, we plugged in one API and got exactly what our users needed: clear positions and complete transaction history. It let us stay focused on our product vision." — Abhisek Tiwari, CTO at Avici

What's on the roadmap

Avici is just getting started. Here's what's coming:

Privacy-preserving transactions: shielded activity that stays compliant. Built to work on any chain, with view keys available to regulators on request. Privacy and compliance aren't trade-offs: Avici is building them as the same thing.

Onchain yield: your stablecoins shouldn't just sit there. Earn directly from your wallet, no third-party platform required.

Onchain credit scores: FICO-style lending comes to crypto. No traditional bank in the loop. A white paper on the lending model is dropping soon.

Avici Business expansion: full-stack financial infrastructure for companies of every size, on every continent.
