Banxa

Banxa is a regulated fiat-to-crypto and crypto-to-fiat payment infrastructure provider serving businesses that need compliant, global on-ramp and off-ramp capabilities. It supports Solana (SOL) alongside more than 100 other digital assets, and operates through an API and SDK layer that lets wallets, exchanges, and fintech platforms embed crypto purchasing directly into their products. Clients include Trust Wallet, Kraken, OKX, KuCoin, MetaMask, and Phantom.

Background and founding

Banxa was founded in 2014 by Domenic Carosa, a serial entrepreneur with a background in internet infrastructure and media, and Holger Arians, who discovered Bitcoin in 2013 when his business partner received mining equipment from China. The pair identified a structural problem in early crypto adoption: retail investors had no compliant, easy-to-use path from traditional bank accounts into digital assets. Exchanges at the time relied on risky bank transfers to unregulated offshore venues, and regulators were beginning to scrutinise those flows. Banxa was designed from the outset as a compliance-first gateway that would meet regulatory expectations before the industry was forced to.

The company listed on the TSX Venture Exchange as Banxa Holdings Inc. (BNXA), providing access to public capital markets to fund its licence-acquisition and regional expansion strategy. The product was formally incorporated in 2019 and grew its commercial footprint steadily through the 2021 and 2022 market cycles.

In June 2025, Hong Kong-listed OSL Group — Asia's leading stablecoin trading and payment platform — announced an agreement to acquire all outstanding Banxa shares at C$1.55 per share, valuing the transaction at approximately CAD $85.2 million (roughly USD $62 million). The acquisition received overwhelming shareholder approval (98.3% in favour) and closed on January 2, 2026. Banxa now operates as a wholly owned subsidiary of OSL Group. The combination brings Banxa's 40-plus regulated trading and payment licences under OSL's broader stablecoin and payment network, with an explicit goal of accelerating global compliant payment infrastructure.

Licensing and compliance

Before the acquisition, Banxa held one of the most extensive regulatory footprints of any on-ramp provider, including 37 US Money Transmitter Licences (MTLs) covering individual state requirements, an Australian Digital Currency Exchange licence, a Canadian Money Services Business (MSB) licence, a Lithuanian digital asset licence, a Dutch crypto services registration, and a UK crypto asset service provider registration. Following full implementation of MiCA (EU Regulation 2023/1114) in July 2026, Banxa holds authorisation as a crypto-asset service provider under the MiCA framework, enabling it to serve EU clients across all member states under a single passportable licence without requiring separate VASP registrations in each country.

This regulatory depth is commercially significant: partners integrating Banxa's API inherit the licences and AML/KYC infrastructure rather than having to acquire their own regulatory approvals. Banxa manages document verification, liveness checks, AML screening, and transaction monitoring on behalf of its B2B clients, who are shielded from the compliance overhead of operating a direct crypto payment service.

How the platform works

Banxa offers two primary integration architectures. The hosted checkout model uses a Banxa-branded redirect or embedded iFrame, requires no backend work for core flows, and can be live in a sandbox environment within minutes. The native API is a fully headless solution where the partner's own interface handles all user interactions, with Banxa's HMAC-authenticated server-to-server calls driving the transaction lifecycle invisibly in the background. React Native, iOS, Android, JavaScript, and Python SDKs are available alongside standard REST API documentation. Production deployment timelines range from days to two weeks depending on integration complexity.

On the on-ramp side, a user selects a cryptocurrency and a fiat amount, authenticates their identity, selects a payment method, and provides a wallet address. Banxa routes the payment, handles settlement, and delivers the digital asset. On the off-ramp side, the process is reversed: the user submits cryptocurrency and receives fiat via the payment rail of their choice. Off-ramp requires per-account configuration and must be enabled for a partner's account before sell orders can be created.

Webhook notifications manage the transaction lifecycle asynchronously, informing partner systems of status changes without polling. Large orders — up to USD $500,000 per transaction — are accommodated through Banxa's direct liquidity arrangements, which distinguishes it from consumer-focused on-ramps capped at lower limits.

Supported assets and payment methods

SOL is supported on Banxa for both buy (on-ramp) and sell (off-ramp) transactions with no geographic restrictions listed in documentation. Beyond SOL, Banxa supports a range of Solana ecosystem tokens including JUP (Jupiter), as well as major assets across other chains including BTC, ETH, USDC, USDT, and dozens of altcoins across 100-plus cryptocurrencies in total. The platform covers 30-plus fiat currencies and is listed as an option for buying Solana in over 180 countries.

Payment methods span credit cards, debit cards, bank transfers, Apple Pay, Google Pay, PayPal, Klarna, and local rails such as iDEAL (Netherlands) and SEPA (European Union). Local payment method coverage is a deliberate competitive advantage: markets like India, Brazil, and the United States have localised payment rails that card-first global competitors struggle to access, and Banxa's regional office and licence strategy was built specifically to tap those rails.

Developer and business tools

For B2B clients, Banxa provides virtual accounts, foreign exchange functionality, and treasury management services alongside the core on-ramp and off-ramp products. Smart accounts and wallet management tools extend the platform toward multi-currency asset management. Token listing capabilities let exchanges and protocols expand the set of purchasable assets without building separate payment infrastructure.

The platform is positioned for a range of business types: payment service providers (PSPs), eCommerce platforms, fintech companies, cryptocurrency exchanges, and digital wallet providers. The hosted widget, API, and React Native SDK provide integration paths appropriate for each segment, from merchant-side redirects to deep in-app fiat-to-crypto flows.

Ecosystem integrations and recent expansion

In November 2025, Banxa announced integration with the Polkadot ecosystem, bringing on-ramp and off-ramp access to DOT and ecosystem stablecoins for platforms including Moonbeam, Bifrost, and Hydration. In April 2026, Banxa joined as a launch partner for Kite Mainnet, an infrastructure layer for autonomous AI agents, providing fiat payment rails across more than 180 countries for agent-driven transactions.

As part of OSL Group, Banxa's roadmap is aligned with OSL's USD $200 million capital raise targeting stablecoin and payment network expansion globally — a direction that complements Solana's growing stablecoin infrastructure, including USDC and USDT volumes processed natively on the network.

Solana ecosystem relevance

Solana's low transaction fees and high throughput make it a natural settlement layer for consumer payment applications, but the friction of acquiring SOL or Solana-based stablecoins from fiat remains a barrier for users without existing crypto holdings. Banxa addresses that gap directly: SOL is a natively supported buy and sell asset, and Phantom — Solana's most widely used self-custody wallet — is a listed Banxa client, meaning Phantom users already interact with Banxa's infrastructure when purchasing SOL directly within the wallet.

The combination of Banxa's regulatory standing, broad payment method coverage, and demonstrated Solana ecosystem partnerships makes it a relevant piece of fiat infrastructure for Solana projects requiring compliant on-ramp capability without building a payment licence stack from scratch.

Summary

Banxa is one of the most regulated and geographically broad fiat-to-crypto gateway providers in the market. Founded in 2014, it accumulated an extensive licence portfolio across the US, EU, UK, Canada, and Australia, then was acquired by Hong Kong-listed OSL Group in early 2026. Its B2B API model lets Web3 projects — including Solana wallets and DeFi applications — embed compliant fiat-to-crypto and crypto-to-fiat flows without independent regulatory overhead. SOL is a directly supported asset for both purchase and sale across 180-plus countries through a wide range of local payment methods.
