Since the issuance of coins and a series of tariff operations before Trump took office, the cryptocurrency market has been in a volatile downward trend, but against this background, the stablecoin and cross-border payment tracks have been emerging with new projects and worthy of attention. In this article, BlockBeats sorted out the startups related to the cryptocurrency field in the latest program W25 of the well-known incubator Y Combinator, of which four are related to payment or stablecoins, for readers' reference only.
BlindPay
BlindPay is a stablecoin payment interface that helps businesses enable global fund transfers through fiat, stablecoins and multiple blockchain networks. BlindPay handles all the complex compliance and regulatory requirements, allowing businesses to focus on their core business.
BlindPay provides fiat payment gateway integration, allowing developers to integrate it into their applications with minimal code. Its SDK supports multiple programming languages and frameworks, and is supported by developer-friendly REST APIs with public OpenAPI documentation. BlindPay is compatible with multiple blockchains and major stablecoins, and can directly integrate with local payment systems such as SPEI in Mexico, Pix in Brazil, PSE in Colombia and Transfers in Argentina. The platform provides a separate sandbox and production environment, with unique API keys and Webhooks, and supports real-time payment tracking and transaction monitoring.
The founding team includes Bernardo Simonassi, who developed the first stablecoin-based payroll platform and was responsible for instant payment solutions at PicPay; Joao Borges, who founded a large Brazilian blockchain startup and is a contributor to the Nouns DAO ecosystem, selected for the Forbes 30 Under 30 list; Gabriel Lyra, who was responsible for financial infrastructure at LendingClub and infrastructure optimization at AWS; and Gustavo Marinho, who focused on Latin American financial products, was responsible for the lending market and instant payments at PicPay, and founded Dropull.
Infinite
Infinite is a stablecoin payment processing platform that provides turnkey APIs and SDKs for businesses to enable global instant fund transfers at a fraction of the cost of traditional solutions.
Infinite partners with startups and mid-sized companies related to global payments, contractor payments, and financial management, covering multiple verticals. Its services include creator economy payments, helping platforms reduce payment costs and increase payment success rates; global payroll, expanding coverage and optimizing tax compliance; cross-border payments in logistics, accelerating settlement and reducing fees; e-commerce platform payments, providing low-cost payment solutions for global sellers and service providers; stablecoin asset management and global remittances for neobanks and SME banks in emerging markets; and instant local cash-outs for esports and gaming.
The founding team includes Nikhil Srinivasan, co-founder and CEO of Infinite, who was previously a platform product manager at Sardine and Coinbase, and Raj Lad, co-founder and CTO of Infinite, who was previously the head of payment technology at Sardine, leading global stablecoin payments and credit risk flow products.
Karsa
Karsa is a stablecoin digital bank serving emerging markets, where users can deposit funds through local payment methods, purchase US dollar stablecoins, deposit funds into US bank accounts for savings, and spend globally through a Visa card.
From the user's perspective, the experience is similar to a bank - but under the hood, Karsa provides liquidity by integrating with a network of verified peer-to-peer stablecoin traders, with user deposits actually paid to these traders.
The founders are Shahryar Hasnani, who previously served as BD for an Ethereum infrastructure startup, and Dale Wilson, who was previously the lead developer of a Layer 1 AI blockchain protocol.
PAX Markets
PAX is the world's first crypto trading platform to adopt a single-chip architecture instead of a traditional data center. By reducing the distance between trading servers to the nanometer level, PAX achieves unprecedented trading speeds. This technical advantage creates immense value for high-frequency trading clients, while also benefiting all participants through a zero-fee + cashback mechanism on every trade.
The fastest trading platforms currently have a round-trip latency of 30 microseconds, which PAX has compressed to 30 nanoseconds (1000x faster). The λ API allows participants to submit orders in response to market events, including canceling orders due to price level drops after large trades, and placing market orders based on events from different assets using local or remote market data.
PAX co-founders Pete Stevenson and Benjamin Kilimnik have years of high-frequency trading experience across crypto and traditional markets.
Axiom
Axiom is a decentralized finance trading platform that currently offers meme coins, perpetual contracts and yield products. According to official data, the platform has already reached a monthly recurring revenue of $10 million and a monthly net profit of $5 million since its launch.
