Revolut Launches EURR Stablecoin in Partnership with Stripe's Bridge
Revolut has launched EURR, its first Euro-pegged stablecoin, in partnership with Stripe. Although marketed as Revolut Euro, the token is legally issued by Bridge Building S.A., a Luxembourg-licensed e-money institution and subsidiary of Stripe (acquired for $1.1 billion). Revolut Digital Assets Europe Ltd serves as the sole distributor. Initially available to select customers in Denmark, Poland, and Portugal, EURR is slated for expansion across the European Economic Area (EEA) later this year. Compliant with EU MiCA regulations, each token is backed 1:1 by Euro reserves. The token currently operates on Ethereum and Polygon, with support for other networks like Solana and Arbitrum planned for the future.
Revolut Launches EURR Stablecoin; Callstack Acquires Margelo for €20M
This digest covers two major developments in fintech and mobile engineering. First, Revolut is launching its first euro-backed stablecoin, EURR, initially available in Denmark, Poland, and Portugal, with plans to expand across the European Economic Area. The stablecoin is issued by Luxembourg-based Bridge, a subsidiary of Stripe, while Revolut acts as the distributor. Second, Polish software firm Callstack is acquiring Vienna-based React Native engineering company Margelo in a deal valuing Margelo at over 20 million euros. Margelo is highly regarded for its open-source libraries, including Nitro Modules and VisionCamera, used by major platforms like Discord and Coinbase. Callstack, backed by Viking Global Investors, intends to integrate Margelo's performance technology to support its enterprise clients as AI agent technology shifts software development toward native architecture and performance optimization.
FinTech Shift: Agentic Trading and Stablecoin Rails Expand
Three fintech developments highlight a shift toward agentic AI and stablecoin-native payment infrastructure. Revolut engineers connected Anthropic’s Claude to a Revolut X API using the Model Context Protocol (MCP) and ran a working market‑making workflow (inventory, quoting, sizing, execution, monitoring) in roughly 30 minutes. Major card networks and payments players are moving stablecoins from pilots to production: Stripe’s Bridge (acquired for $1.1B) is expanding a Visa-backed stablecoin card program globally, and SoFiUSD will become a settlement option across Mastercard via Galileo’s 130 million white-label accounts. Meta is testing stablecoin payments across its apps (possible H2 2026 rollout) and is pursuing distribution rather than issuing a proprietary token. Collectively these moves shift the competition toward payment and API infrastructure, and raise regulatory and permissioning questions for agent-driven finance.
