What KAST does
KAST (legal entity Troia Corp) is a stablecoin-powered financial technology company founded in July 2024 by Raagulan Pathy, the former Singapore CEO of Circle. Headquartered in Singapore with a New York operational base, KAST operates a unified global money app that combines self-custodial on-chain wallets (Privy) with fiat rails (Bridge/Lead Bank, Member FDIC) to issue virtual USD accounts with US routing numbers and EU IBANs, Visa-branded debit cards accepted at 150M+ merchants across 170+ countries, and cross-border payouts in 15+ currencies via PIX, SPEI, ACH, SEPA, and SWIFT. The platform also offers yield-bearing vaults (USD Prime up to 3.3% APY via USDKY on the M0 protocol, and Gauntlet Alpha up to 7% APY on Base), with assets self-custodied via Privy on Solana.
The product surface spans six integrated sub-products — Global Accounts, KAST Earn, Crypto Cards, KAST Pay, Memberships (Standard free, Premium $1,000/year, Private $10,000/year), and KAST Business (waitlisted B2B offering with cloud-bill savings and expense management) — plus co-branded card programs with Pudgy Penguins and Solana. As of March 2026, KAST reported over one million users, ~$5 billion in annualized transaction volume, revenue growth of 15–20% month-over-month, and a 2026 ARR target of approximately $100 million. The company is privately held, has raised $90 million in total ($10M seed led by HSG and Peak XV Partners in December 2024; $80M Series A co-led by QED Investors and Left Lane Capital in March 2026 at a ~$600 million valuation), and counts DST Global Partners among its investors.
KAST monetizes through tiered annual memberships, Visa interchange and FX spread on card transactions, cross-border payout and FX margins on KAST Pay, and an in-app affiliate program (currently passing through 100% of vault yield to users with future fee introduction flagged). Its go-to-market is primarily direct-to-consumer self-serve via iOS, Android, and web, supplemented by community-driven waitlists for co-branded cards and a Y Combinator B2B bundle. The strategic posture is institutional-grade, evidenced by the hire of former SEC senior advisor Stephanie Allen, the appointment of ex-Binance CCO Brad Jaffe, and active membership in The Digital Chamber.

KAST product offering
Product offeringCore offering
KAST is a global money app powered by stablecoins that lets users open virtual USD and EUR accounts, fund them with USDC/USDT/USDe, earn yield on idle balances through treasury-backed and DeFi vaults, send cross-border payouts in 15+ local currencies, and spend at 150M+ merchants via Visa debit cards. The product is delivered through a mobile and web application operated by Troia Corp and is available in 170+ countries with tiered memberships and an emerging B2B waitlist.
Product overview
KAST is a single unified product — a global money app powered by stablecoins — rather than a loosely connected suite of standalone tools. The core app, branded simply "KAST" (operated by Troia Corp), ties together six tightly integrated sub-products: KAST Global Accounts (USD/EUR virtual accounts via Bridge and Lead Bank), KAST Earn (USD Prime Vault and Gauntlet Alpha Vault yield products), KAST Crypto Cards (Visa-branded debit cards with Standard/Premium/Private designs), KAST Pay / Global Payouts (cross-border transfers and Payment Links), KAST Business (waitlisted B2B financial infrastructure), and KAST Memberships (account-level subscription tiers). Two co-branded sub-products extend the card line: the Pengu Card with Pudgy Penguins and the Solana x KAST cards (Solana Card, Illuma, Gold, Solid Gold), the latter also tied to the KAST Validator Solana staking program. Supporting programs — KAST Cloud (stablecoin cloud-bill payments) and the KAST Affiliate Program — round out the platform, with KAST Academy serving as the editorial/education layer.

KAST competitors and assessment
Company assessmentDirect peers
- MoonPay: MoonPay provides crypto on-ramp and payment infrastructure that competes with KAST's stablecoin-funded spending account on the fiat-to-crypto and crypto-to-fiat conversion layer. Both serve global users seeking seamless stablecoin-to-merchant payment flows.
- Crypto.com: Crypto.com operates one of the largest crypto card programs globally, with tiered memberships (similar to KAST Premium/Private), cashback rewards paid in CRO, and a Visa card accepted worldwide. It is a direct competitor in the premium crypto card and stablecoin spending category.
- RedotPay: RedotPay is the leading crypto card issuer by spending volume, holding 61% of cumulative crypto card spending volume as of June 2026 versus KAST's 15%. It competes head-on with KAST on stablecoin-funded Visa cards, global account issuance, and crypto-to-fiat spending for users in emerging markets.
- Bybit Card: Bybit's card program allows users to spend crypto balances at Visa merchants globally with cashback rewards. As a major crypto exchange with a card product, it competes for the same crypto-native spending user base that KAST targets.
- Wirex: Wirex is a long-standing crypto card and payment platform offering multi-currency accounts, debit cards, and crypto earning features across 130+ countries. It overlaps with KAST on crypto-native Visa cards, stablecoin spending, and emerging-market user segments.
- Nexo: Nexo offers a crypto-backed Visa card, yield products on stablecoins, and global account services. Its dual product of yield generation plus card spending directly mirrors KAST's Earn vaults plus Crypto Cards combination.
- Strike: Strike is a Bitcoin and stablecoin payments app offering a debit card, global payments, and yield features. It targets similar use cases of using digital dollars for everyday spending and cross-border transfers, overlapping with KAST's Crypto Cards and KAST Pay products.
- BitPay: BitPay is a long-established crypto payments processor offering prepaid Visa cards, bill pay, and merchant settlement. It overlaps with KAST on the stablecoin-to-Visa spending value proposition for users converting crypto balances to everyday purchases.
Broad incumbents
- Wise: Wise is a leading cross-border payments platform offering multi-currency accounts and low-cost FX transfers. It overlaps with KAST's Global Accounts and KAST Pay on cross-border money movement, but Wise does not specialize in stablecoin-funded accounts or yield-bearing balances.
- Revolut: Revolut is a large, established neobank with 40M+ users offering multi-currency accounts, cards, and crypto features. Blockworks Research places it alongside KAST in defining the stablecoin-native neobank category, but Revolut's product breadth far exceeds KAST's specialized stablecoin focus.
