Beam

Beam was a Solana-compatible stablecoin Payment Service Provider (PSP) that gave businesses a single API to move money across cryptocurrency rails and traditional banking networks simultaneously — eliminating the need for separate integrations for crypto and fiat. The company was founded in October 2022, processed over 350 million dollars in global payments, and was acquired by payments infrastructure company Modern Treasury in October 2025. It no longer operates as an independent product.

The Problem Beam Addressed

Businesses that wanted to accept or disburse stablecoins faced a fragmented landscape: ACH, wires, real-time payments networks, and on-chain settlement all required separate vendor relationships, reconciliation workflows, and engineering overhead. For companies operating across borders — particularly those serving users in markets underserved by traditional banking — stablecoins offered a faster and cheaper path, but plugging into both crypto and fiat worlds at once was technically complex.

Beam's thesis was that a unified PSP layer, purpose-built for stablecoin and fiat orchestration, could collapse this complexity into one integration and one API contract.

Core Mechanism

Beam's platform provided a single API covering both fiat and digital-asset payment rails:

• Stablecoin settlement: Businesses could accept and disburse USDC and other stablecoins directly to and from on-chain wallets.
• Solana SPL token support: Beam explicitly supported SPL tokens on Solana, enabling businesses and end users to convert Solana-native assets — including Solana USDC — to USD in a single step, bridging Solana's fast, low-cost settlement layer to fiat bank accounts without routing through cross-chain bridges.
• Traditional payment rails: ACH, wire transfers, RTP (Real-Time Payments), FedNow, and Push-to-Card were all accessible through the same API, meaning a business did not have to choose between crypto and fiat — Beam handled both sides.
• Compliance layer: Onboarding included KYC identity verification and on-chain wallet screening, embedding regulatory compliance directly into the payment flow rather than leaving it to the integrating business to construct independently.

The architecture mirrored what a conventional PSP provides for card acceptance, but extended it to blockchain-settled value. Beam positioned itself explicitly as "the first stablecoin-based PSP."

Products and Features

Beam's primary offering was its Payments API, aimed at software companies, fintech applications, and enterprises. Key capabilities included:

• Crypto-to-fiat off-ramp: End users or businesses could send supported crypto assets — including Solana SPL tokens and USDC — to a Beam-generated address; Beam converted them and deposited the fiat equivalent to a linked bank account or debit card.
• Stablecoin disbursement: Outbound payment flows such as payroll, vendor payments, and cross-border remittances could be settled on-chain rather than through slower ACH batch processing.
• Beam Hub: A dashboard for managing payment flows, reconciliation, and reporting across all connected rails.

A notable customer was Sling Money, a global remittance application that used Beam's Payments API to expand its cross-border payment capabilities and reach a wider user base. This illustrated Beam's B2B model: it sold infrastructure to product companies rather than serving consumers directly.

Solana Ecosystem Fit

Solana's role in Beam's stack was as the settlement layer for SPL token flows. With sub-second finality and low per-transaction costs, Solana was a natural fit for a payment service trying to undercut the economics of traditional payment networks and enable near-instant cross-border settlement. Beam's explicit support for SPL assets meant that Solana-native USDC and other SPL tokens could be accepted, cleared to fiat, and deposited to bank accounts without requiring the end user or integrating business to navigate cross-chain wrapping or bridge mechanics.

Within Solana's payments ecosystem — alongside projects such as Sphere and CODE — Beam occupied an enterprise-facing position: a compliant, API-first off-ramp layer that product companies could integrate without deep blockchain engineering expertise.

Team and Background

Beam was founded by Dan Mottice, who previously led Visa's crypto settlement products and the Visa Direct Payouts division. His background positioned Beam at the intersection of institutional payments and emerging crypto infrastructure, shaping the company's focus on compliance-forward design and enterprise API architecture rather than consumer-facing crypto wallets.

Funding

Beam raised 14 million dollars in total capital. The final independent funding round, announced in May 2025, was 7 million dollars led by Castle Island Ventures, with participation from Archetype, Arca, A*, and Soma. At that point the company had processed over 275 million dollars in cumulative payment volume. Its pre-acquisition valuation was approximately 44 million dollars according to Pitchbook data.

Acquisition by Modern Treasury and Current Status

On October 22, 2025, Modern Treasury — a payments infrastructure company valued at approximately 2.1 billion dollars — announced it had acquired Beam in an all-stock transaction valued at approximately 40 million dollars. Modern Treasury's CEO described the deal as combining their "fiat DNA" with Beam's "stablecoin DNA," reflecting the strategic fit between Modern Treasury's existing bank-connected payment platform and Beam's stablecoin orchestration layer.

Dan Mottice joined Modern Treasury as Head of Stablecoins following the acquisition. Existing Beam customers, including Sling Money, experienced no service interruption; their integrations were migrated into Modern Treasury's expanded platform, which now offers unified fiat and stablecoin payment capabilities — including Solana stablecoin off-ramps — through a single API.

The getbeam.cash domain now redirects to moderntreasury.com, and the @beam_cash X account carries the label "beam (acq Modern Treasury)." Beam no longer exists as a standalone company or independent product offering.

Security and Audits

No third-party smart contract audits or on-chain security reports were publicly documented by Beam for its Solana integration. The compliance framework Beam described was regulatory in nature — KYC, AML, and wallet screening — reflecting its position as an off-chain payment service that settled through on-chain rails rather than operating autonomous smart contracts holding user funds.
