CopperX

CopperX (spelled Copperx by the company) is a stablecoin payments and banking app for firms and freelancers outside the US. It is not Copper, the crypto custodian. With CopperX you can take crypto payments, get US dollar and euro account details without a US company, pay contractors abroad and spend with a Visa card. It runs on Solana and the main Ethereum-style chains. Tarun Mangukiya founded it in 2022, and it works from the UAE and India. Since June 2026 its app for freelancers has been moving to a new brand, KOSH. Its website says it is "not a bank or a money services business". Licensed partners handle the cash side.

How CopperX works

CopperX has two layers. The first is a crypto payment gateway. Merchants accept stablecoins and other tokens, and the money goes straight to their own wallet. The docs FAQ says: "Copperx does not hold or manage your funds at any point." Card payments run through a merchant's own Stripe account.

The second layer is accounts. A customer gets named US account details. When a client pays by ACH or wire, CopperX turns the dollars into USDC and credits the balance. That balance can fund a Visa card, pay other people or be cashed out to a local bank.

CopperX is a Circle Alliance partner. It uses Circle USDC$0.9990.0%'s USDC, Programmable Wallets, Paymaster and its cross-chain transfer protocol (CCTP).

CopperX payment gateway: crypto checkout, invoices and API

The gateway offers payment links, hosted checkout pages, invoices, subscriptions and promo codes. Developers get an API and webhooks. Others can use payment links with no code at all. The docs list plugins for WooCommerce, Zapier, Stripe, BigCommerce and Magento. Shopify is in private beta, per the homepage.

According to its payment methods page, the gateway takes payments on these chains:

• Solana: SOL, USDC, USDT and several bridged tokens
• EVM chains: Ethereum, Polygon, BNB Smart Chain, Base, Arbitrum and Optimism
• Tron: USDT only

Bitcoin and Binance Pay are still "coming soon". On Ethereum, merchants pay gas of up to $25 a payment, and up to $10 on Tron. They can pass that cost on to the buyer.

CopperX business account and virtual USD/EUR accounts

The virtual USD account is for non-US founders, freelancers and small firms with US clients. CopperX says sign-up takes about five minutes. You then get US account and routing numbers to share. Wires land the same day, and ACH takes one to three business days. Dollars that come in turn into USDC on their own. Business accounts also come in euros and UAE dirhams, with as many virtual team cards as you need.

Payments from people other than the account holder are checked by CopperX before they are accepted. CopperX's pricing page puts these third-party payments at $199 a year.

CopperX payouts and offramp to 90+ countries

The payouts product sends USDC or USDT in bulk to contractors and suppliers. It checks each recipient's identity (KYC) for you. Stablecoin payouts settle within minutes of on-chain confirmation. Payouts to a bank account usually arrive in two to three business days.

CopperX's own pages disagree on reach. The payouts page says 90+ countries. The pricing page says "local rails in 50+ countries", plus wire and SWIFT. Check your country before you rely on it. The pricing page puts bank withdrawals at about 0.5% for customers moving $50,000 or more a month. Indian users can buy the bank certificate that proves foreign income (a FIRC) for $9.

CopperX card and personal account

The personal account is for people paid in dollars from abroad, such as Upwork and Fiverr freelancers or remote staff paid through Deel or Remote. It includes:

• USD and EUR account details
• A Visa card that works with Apple Pay and Google Pay
• 4-5% APY on idle stablecoins, paid daily with no lock-up
• Local offramps in India, Indonesia, the UAE, the EU, the UK and Latin America

KOSH Money: the CopperX rebrand for freelancers

CopperX announced KOSH at Solana Breakpoint on December 12, 2025 (Crypto Economy). It was pitched as a Solana bank for freelancers and small firms. In Tarun Mangukiya's Breakpoint 2025 keynote, he promised US account details in five minutes and a stablecoin card. He also promised a "pay later" option that would let you borrow against your SOL.

KOSH Money went live on Product Hunt on June 12, 2026. Its tagline was "USD account & credit cards for freelancers & creators", aimed at Asia. The KOSH site still sends new users to sign up at Copperx.io. It says their accounts will move to KOSH later. The SOL loan feature is not on either site today, so treat it as a promise, not a product.

A QuickNode case study shows how KOSH accounts work. Each user gets a smart contract wallet. On Solana it is a Squads wallet, and on other chains it is a Safe wallet. KOSH watches more than 110,000 wallet addresses across five chains.

Who CopperX is for

CopperX suits people and firms outside the US who bill in dollars or euros but can't easily get a US bank. Think of an Indian agency with US clients, a crypto company paying contractors in many countries, or a freelancer paid through Upwork. Its homepage lists customers such as FanTV, Router, NodeOps and Hadron.

It is a poor fit in three cases. You need a regulated bank account with deposit insurance. You take most payments on Ethereum, where gas fees add to each payment. Or you need Bitcoin checkout now. US firms that already bank with Mercury or similar gain less from it.

Is CopperX safe? Custody, licensing and risks

Who holds your money depends on the product. The gateway never holds funds: payments go straight to the merchant's wallet. Account balances are different. The USD account page says CopperX uses "institutional custody for stablecoin balances". KOSH gives each user a smart contract wallet. Read the terms for the product you use. Don't assume it is all self-custody.

Other risks:

• No bank behind it. CopperX is a technology company, not a bank or money services business. Fiat accounts, cards and offramps depend on unnamed licensed partners, so a partner leaving could cut off a service. Stablecoin balances are not deposit-insured.
• No public audits. We found no published security audit and no on-chain programs listed for CopperX. The safety of smart contract wallets rests on Safe and Squads, not on CopperX code.
• Brand change. Personal customers are being moved from CopperX to KOSH. Expect changes to account terms and support channels during the move.
• Mixed messages in its own materials. The country count (50+ or 90+) varies by page. Fees are not all published, and a September 2026 RFP.wiki review found little public detail on compliance tooling.
• Little public information. We found no public funding figures. The @CopperxHQ X account had no posts in the 60 days to October 22, 2026.

CopperX alternatives

• Wise and Payoneer: the traditional options for freelancers. KOSH's launch pitch says they often limit or delay receiving USD in many Asian countries.
• KAST and RedotPay: stablecoin cards for people who mainly want to spend crypto, not run business payments.
• BVNK and Request Finance: stablecoin payment and invoicing tools for businesses that RFP.wiki lists as direct competitors.

Next to these, CopperX's draw is breadth. Crypto checkout, dollar accounts, payouts and cards all sit in one place.
