Fin

Fin is a high-value payments platform built on Solana, designed to replace the slow and expensive wire-transfer infrastructure that global enterprises and financial institutions depend on today. Founded by former Citadel quantitative researchers Ian Krotinsky and Aashiq Dheeraj, the company bills itself as "the OS for cross-border payments"—a single network for sending and receiving large sums internationally, using USDC and USDT stablecoin rails instead of legacy correspondent banking.

From TipLink to Fin

Fin traces its origins to TipLink, a Solana-native tool the same founding team built to let anyone send cryptocurrency through a simple URL link, without requiring the recipient to have a wallet. TipLink earned broad adoption in the Solana ecosystem for its frictionless onboarding approach: funds were embedded in links that could be opened and claimed by anyone, covering gas fees and eliminating the technical barriers that normally accompany on-chain transfers.

In late 2025, the team rebranded to Fin and pivoted the product's focus decisively upmarket. Where TipLink democratized small on-chain payments, Fin targets the opposite end of the spectrum—transactions in the hundreds of thousands or millions of dollars that currently travel through SWIFT, correspondent banking chains, and ACH networks over two to five business days. The Solana foundation remains: Fin's payment infrastructure continues to run on Solana's high-throughput ledger, which can process tens of thousands of transactions per second at a fraction of a cent per transaction.

Product Architecture

Fin describes its offering as a modular payment operating system with six core capabilities:

Pay In lets businesses collect funds globally via bank transfers, wires, and stablecoins through a single integration. Pay Out routes payments to recipients in more than 40 countries and 40+ currencies, with support for bulk and automated disbursement workflows. Crypto Payments enables direct acceptance from leading exchanges and crypto wallets.

International Virtual Accounts provides multi-currency accounts denominated in USD, AED, EUR, and INR, giving businesses a local presence for receiving funds without setting up foreign legal entities. Named USD SWIFT allows companies to send and receive international wires through personal entity accounts. Wallet as a Service exposes the full payments stack as an API or white-labeled mobile experience, letting other fintechs and payment providers embed Fin's rails into their own products.

Under the hood, Fin unifies all payment flows into a single USDC balance and handles bridging, swapping, and gas fees automatically. A user or business can send USDT on Tron, for example, and the recipient can withdraw directly to a bank account in their local currency—without touching the underlying mechanics. Settlement on most corridors completes in under an hour, often within minutes. Fin holds regulatory licenses as a payment services provider, VASP, or bank-sponsored entity across more than 30 countries.

The platform's pricing is transparent: transaction fees range from 0.01% to 0.3% depending on corridor and volume. Fin also earns interest on stablecoin balances held within the platform, creating a second revenue stream.

Founders and Team

Ian Krotinsky, CEO, spent six years at Citadel as a quantitative portfolio manager and trader after earlier work as a programmatic trader at Goldman Sachs. Aashiq Dheeraj, CTO, worked as a Quantitative Researcher at Citadel Securities. Both left Citadel in 2022 to build what would become TipLink, identifying international money movement as a persistent pain point while working on other side projects.

Their financial engineering background shapes how Fin positions itself: not as a crypto product looking for users, but as a payments infrastructure play aimed squarely at displacing legacy systems. Krotinsky has described the opportunity in terms of incumbent inertia: "It's difficult for incumbents to rip out their whole infrastructure and build a proper payments product in the new global stablecoin regime."

Funding and Investors

In December 2025, Fin announced a $17 million Series A round led by Pantera Capital. Sequoia Capital and Samsung Next participated alongside Pantera in the round.

Ryan Barney, a partner at Pantera Capital, framed the investment around the team's track record of making blockchain-native products accessible to mainstream users: "This team has repeatedly shown they can build crypto products that don't feel like crypto—simple, intuitive, and ready for real-world users."

The round funds team expansion, product development, and regulatory coverage in new geographies. At the time of announcement, Fin was entering a pilot phase with businesses in the import and export sector—a segment where high-value, time-sensitive cross-border transfers are routine but poorly served by existing infrastructure.

Target Market and Competition

Fin positions its primary competition as large financial institutions—JPMorgan Chase, Barclays, and similar global banks—rather than consumer payment apps. The thesis is that enterprises and financial institutions moving large sums internationally are underserved by existing alternatives: wire transfers are slow, opaque, and expensive; crypto rails historically required technical sophistication; and stablecoin-based solutions have been fragmented across chains and compliance frameworks.

The platform's design deliberately avoids exposing users to on-chain complexity. Recipients and senders interact with a banking-style interface while the stablecoin and Solana infrastructure operates in the background. Fin supports inbound transfers from any major stablecoin chain, converting to its unified USDC balance, and outbound to bank accounts in local currencies.

Target verticals include fintechs, payment service providers, luxury goods retailers, gaming platforms with international payouts, payroll services, and import/export businesses. The Wallet as a Service offering also positions Fin as a B2B infrastructure provider, enabling other fintechs to white-label its cross-border rails.

Solana Context

Fin's continued reliance on Solana reflects the network's growing role as a preferred settlement layer for institutional payment applications. Solana's throughput, sub-second finality, and near-zero transaction costs make it technically suited to high-volume, high-value payment flows that would be prohibitively expensive on Ethereum mainnet. The network's stablecoin supply—roughly $6.7 billion in USDC alone as of mid-2026, second only to Ethereum—provides the liquidity depth that enterprise payment products require.

For Fin, Solana also provides continuity: TipLink was Solana-native from inception, and the founding team built its technical expertise and early user base within that ecosystem before scaling to the institutional payment market.
