Uniwire (CryptoChill)

Uniwire is an enterprise-grade cryptocurrency payment gateway and wallets-as-a-service platform that enables businesses to accept, convert, pay out, and store digital assets across multiple blockchains, including native support for Solana.

Background and Rebrand

The company launched in 2018 under the name CryptoChill. Its founding team also created CryptoPanic, a widely used cryptocurrency news aggregator, giving the founders a clear view into payment friction across the industry before building their own infrastructure solution.

On April 21, 2025, CryptoChill formally rebranded to Uniwire, citing growth beyond its original scope and a broadened mission to serve global digital finance markets. The rebrand was a corporate name and domain migration only; existing services, APIs, and integrations were preserved with automatic URL redirects from cryptochill.com to uniwire.com. The new name was chosen to reflect the company's role as a connector across markets and blockchain networks.

Uniwire operates through multiple legal entities: Uniwire AG, incorporated in Zug, Switzerland; Uniwire SVG LLC, based in St. Vincent and the Grenadines; and a planned presence in El Salvador as crypto-friendly regulation there matures.

What It Does

Uniwire gives businesses a full-stack infrastructure for accepting cryptocurrency payments. Unlike simpler payment buttons that redirect to a third-party checkout, Uniwire provides non-custodial and custodial options with dedicated wallet addresses per customer, automated consolidation of small balances, and real-time transaction detection.

The platform processes payments across Bitcoin (including Lightning Network), Ethereum, Litecoin, Solana, Polygon, Tron, XRP, TON, and major stablecoins. Solana support covers SOL (native), USDT-SOL, USDC-SOL, Wrapped SOL (WSOL), BONK, and the Official Trump token, with additional SPL tokens available on request. Clients can request integration of other Solana-based assets.

Target verticals include iGaming and online casinos, forex and CFD brokerage, prop trading firms, crypto exchanges, real estate, ecommerce, escrow services, and luxury brands. Supported CRM and cashier integrations include PaymentIQ, BridgerPay, and Praxis, which are standard infrastructure in regulated online gambling and financial services.

How It Works

Businesses integrate via one of several methods:

• A hosted dashboard for manual management
• A full REST API and SDK for automated payment flows
• A WooCommerce WordPress plugin for retail merchants
• Third-party cashier service integrations for operators already running existing payment stacks

The platform generates unlimited, non-expiring wallet addresses, meaning each customer or invoice can have a unique deposit address without the address recycling that leads to attribution problems. Incoming transactions are detected in real time, and small incoming amounts are automatically consolidated to reduce on-chain fragmentation.

Manual and automatic coin conversion and payout options allow operators to sweep incoming crypto to stablecoins or fiat-equivalent equivalents on their own schedule. Payouts carry no fee under Uniwire's pricing model; charges apply only to incoming transactions and conversion operations.

For Solana specifically, the integration leverages the network's throughput of thousands of transactions per second and sub-cent transaction fees, which materially reduces overhead compared to processing the same payment volume on Ethereum mainnet.

White-label deployment is available, letting businesses brand the payment experience as their own without building custody or compliance infrastructure from scratch.

Security

Uniwire's wallet infrastructure is built on Multi-Party Computation (MPC) technology, which distributes private key control across multiple independent parties rather than storing a complete key in any one location. This eliminates single points of failure that have historically led to exchange and payment processor thefts.

The MPC wallet implementation was independently audited by Kudelski Security, a Swiss cybersecurity firm with a track record in cryptographic and blockchain security assessments. Kudelski's validation covers the key management and signing protocols underlying Uniwire's wallet-as-a-service offering.

The platform reports 99.997% uptime, and offers live technical support around the clock for enterprise clients.

Scale and Track Record

By its own figures at the time of the rebrand, Uniwire had processed over $7 billion in total incoming volume with average daily flows in the range of $5–10 million. The company states it has been processing live transactions since 2018, giving it a longer operating history than most crypto payment startups that emerged during the 2020–2021 cycle.

Solana Fit

Solana's combination of high throughput, near-instant finality, and minimal fees makes it practical for the high-frequency, high-volume payment scenarios Uniwire's clients operate. iGaming platforms and prop trading firms frequently process large numbers of small-to-medium transactions where Ethereum gas costs would erode margins or make micro-deposits uneconomical. Solana's fee structure removes that constraint.

Stablecoin support (USDT-SOL and USDC-SOL) is particularly relevant because operators typically want price-stable settlement rather than SOL price exposure. Both assets are liquid and have deep on-chain markets on Solana, and Uniwire's conversion features allow operators to configure automatic sweeps out of SOL into stablecoin positions.

The inclusion of BONK and the Official Trump token indicates Uniwire is tracking demand from clients whose users hold popular Solana meme assets, a market segment that skews heavily toward the iGaming and entertainment verticals Uniwire already serves.
