Brex

Brex is a corporate spend management platform that started as a credit card for startups in 2017 and has since grown into a full-stack financial operating system for businesses. Its core products include corporate cards, expense management, bill pay, business banking, and treasury management, all consolidated in a single dashboard. The platform has always targeted fast-moving companies that find traditional banking too slow, too fragmented, or too rigid.

In September 2025, Brex announced the addition of native stablecoin payments, with Solana chosen as a primary blockchain integration from launch. The Solana Foundation's Head of Stablecoins, Tamar Menteshashvili, confirmed the partnership directly: "Stablecoins are transforming global money movement, and Solana provides the best-in-class infrastructure to power that future. We're excited to see Brex will soon launch stablecoin payments where Solana will be integrated from the start." Brex's own official account stated: "Stablecoin payments are coming to Brex, and @solana will be integrated from the start."

What Brex Stablecoin Payments Does

The product is built around three core functions, all operating within the existing Brex dashboard:

Receive stablecoins as payment. Companies can accept USDC from counterparties and have it automatically converted to USD in their Brex business account. There is no manual reconciliation step and no need for a separate crypto wallet workflow.

Send stablecoins from fiat balances. Businesses with USD in their Brex account can send USDC to any counterparty without first having to acquire crypto elsewhere. Brex handles the conversion and transmission on the backend.

Pay card balances with stablecoins. Brex claims to be the first global corporate card to allow card balance payments in stablecoins, a meaningful operational distinction because it means businesses can settle credit obligations without liquidating crypto through a third-party exchange.

All three functions run on Solana's blockchain infrastructure, using USDC as the initial supported stablecoin. Settlement is instant, operates 24 hours a day including weekends, and requires no intermediaries or correspondent banks for cross-border transfers.

Fee Structure and Conversion

Brex committed to no conversion fees, no hidden costs, and no minimum balances on stablecoin transactions. The conversion rate is 1:1 regardless of transaction size, with the product designed to handle transfers from one thousand to ten million dollars without additional charges. This compares directly to wire transfers, which typically cost between twenty-five and fifty dollars per transaction, take one to several business days, and are unavailable outside banking hours.

Why Solana

The choice of Solana as the blockchain layer reflects the network's characteristics that matter most for payments at institutional scale: sub-second finality, transaction costs that run well under a cent, and throughput that accommodates enterprise volumes without congestion at normal load levels. USDC on Solana has become one of the most liquid stablecoin deployments across any chain, with Circle as issuer and a deep market of crypto-native businesses that already transact in it.

Brex's target customers include companies that hold or receive crypto as part of their normal business: AI firms, blockchain projects, and digital asset companies. These businesses often have USDC on Solana already and have historically needed to convert to fiat, absorb exchange fees and slippage, and wait for settlement before they could pay vendors or card balances denominated in dollars. Brex's integration removes those steps.

Target Users and Early Adopters

Brex positioned the stablecoin product at two audiences. The first is crypto-native companies that run their corporate finances on Brex and want to use their on-chain treasury for operational payments without leaving the Brex platform. The second is traditional businesses newly adopting stablecoins for international payments, who want a bank-grade interface rather than a crypto-exchange workflow.

Three companies joined the initial waitlist and were cited in Brex's launch announcement: Figure, a blockchain-native financial services firm; Solana, the Foundation and ecosystem entity itself; and Alchemy, a web3 developer infrastructure provider. All three run their corporate finances through Brex and signed up to be among the first to use stablecoin payments when they reached general availability.

Technical Context

The stablecoin payments product sits inside Brex's existing financial platform. Users do not need a separate wallet address or a new interface: the stablecoin send and receive functions appear alongside existing banking and card features in the Brex dashboard. Accounting integration is automatic; transactions are categorized in real time, and cash flow visibility is maintained across fiat and stablecoin balances without manual reconciliation. This keeps the product accessible to finance teams that have no crypto expertise and do not want to manage private keys or interact with on-chain infrastructure directly.

Company Background and Acquisition

Brex was founded in 2017 by Pedro Franceschi and Henrique Dubugras, initially as a credit card for venture-backed startups that lacked the credit history to qualify for traditional corporate cards. The company expanded to serve mid-market and enterprise customers over time, adding banking, treasury, and expense automation products. By late 2025 it had reached a customer base spanning AI startups, crypto companies, and large technology enterprises.

In January 2026, Capital One announced the acquisition of Brex in a cash-and-stock transaction valued at approximately five billion dollars. The deal closed in April 2026. Brex continues to operate as a distinct product under Capital One, and its stablecoin payments feature remains listed as an active product on the Brex website as of mid-2026.

Solana Ecosystem Fit

Brex's integration is significant for Solana because it routes institutional business payment volumes through the network. Every time a Brex customer sends a vendor payment in USDC, pays a card balance, or receives revenue from a crypto-native client, that transaction settles on Solana. This is the type of real-world, recurring, utility-driven transaction flow — not speculative trading volume — that tends to embed a blockchain into financial infrastructure over time.

The partnership also reinforces Solana's position in the payments segment. Alongside payment processors, card networks, and remittance platforms that have built on Solana, Brex adds corporate spend management to the mix: a layer of the financial stack that handles the day-to-day operating expenditures of businesses rather than consumer or retail transactions. The Solana Foundation's direct involvement as a quoted integration partner, rather than merely a customer, signals that this is a strategic deployment of Solana for institutional payment infrastructure rather than incidental usage.
