StablR: Europe's MiCA-Licensed Stablecoin Issuer on Solana and Ethereum

StablR is a Malta-based electronic money institution (EMI) that issues regulated, fiat-backed stablecoins designed to bridge traditional European finance and blockchain networks. Operating under the European Union's Markets in Crypto-Assets (MiCA) framework, StablR offers two tokens — EURR, pegged to the euro, and USDR, pegged to the US dollar — on both Ethereum and Solana.

The Company and Its Origins

Incorporated in December 2022 through the Dutch holding company Plutus B.V., StablR Ltd. is registered in Birkirkara, Malta. The company was built around a conviction that Europe's regulatory environment, long viewed as a constraint on crypto innovation, could instead become a competitive advantage for institutional-grade stablecoin issuers.

Founder and CEO Gijs op de Weegh brings a background in European fintech infrastructure, having previously co-founded and served as COO of Payvision, a Dutch payment processor. The leadership team includes Corné van der Meijden as Chief Risk and Operations Officer (also a Payvision veteran, where he served as CFO until 2020), Julia Frendo as CFO, and Robin Nijkamp as CTO.

MiCA Authorization

In June 2024, Malta's Financial Services Authority (MFSA) granted StablR an Electronic Money Institution licence under Title IV of MiCA (EU Regulation 2023/1114), authorizing it to issue Electronic Money Tokens (EMTs). This made StablR one of the early EMT issuers formally licensed under MiCA's stablecoin provisions as the regulation came fully into force at the close of 2024.

MiCA's EMT category carries strict requirements: full 1:1 fiat backing, reserves held in segregated accounts at regulated financial institutions, immediate redemption rights for token holders, and ongoing MFSA supervision. EURR launched commercially in July 2024 following authorization, with USDR following as a complementary US dollar-denominated offering.

EURR and USDR: What They Are

EURR (StablR Euro) is a euro-pegged stablecoin collateralized 1:1 against euro reserves held in segregated accounts. USDR (StablR USD) follows the same structure pegged to the US dollar. Both tokens are issued as ERC-20 tokens on Ethereum and as SPL tokens on Solana, enabling seamless transfer to any compatible wallet on either network.

The reserve model keeps fiat backing entirely separate from StablR's operating capital — a structural requirement under MiCA that also offers a layer of protection for token holders distinct from the company's own financial position. By early 2026, EURR had reached a circulating supply of approximately $20 million across both chains.

The tokens target institutional users, payment processors, DeFi protocols, and merchants seeking compliant fiat-on-chain instruments for settlement, treasury management, and cross-border transfers within or into the EU.

Solana Integration

StablR deployed EURR and USDR as Solana Program Library (SPL) tokens, extending MiCA-compliant euro and dollar liquidity into Solana's ecosystem. Solana was chosen alongside Ethereum as an equal first-class deployment target — not a secondary integration — reflecting the network's advantages for payment-adjacent use cases: sub-second transaction finality, low fees, and a dense infrastructure of DEXes, lending protocols, and payment rails.

StablR has announced plans to expand to additional blockchain networks using the Hadron by Tether platform, positioning Solana as the first step in a broader multi-chain rollout.

Tether Investment and Infrastructure

In December 2024, Tether — the world's largest stablecoin issuer by market cap — took a strategic equity stake in StablR. The investment came paired with an infrastructure arrangement: StablR issues and manages its tokens through Hadron by Tether, Tether's tokenization and token-lifecycle platform. In exchange, Tether gains a regulated entry point into the European EMT market through StablR's MFSA-licensed entity.

Paolo Ardoino, Tether's CEO, described the investment as support for "the European digital asset ecosystem" and aligned with promoting compliant stablecoin adoption under MiCA. For StablR, Hadron provides the technical backbone for issuance, reserve attestation workflows, and planned network expansion.

Market Presence

Prior to May 2026, EURR and USDR were listed on more than 15 centralized exchanges, including Kraken, Bitfinex, ByBit, and WhiteBIT — giving the tokens meaningful secondary-market liquidity relative to most MiCA-compliant EMTs in the early post-MiCA period.

May 2026 Security Incident

In May 2026, StablR disclosed a significant cybersecurity incident that affected both EURR and USDR operations. Attackers exploited a critical flaw in StablR's multisignature wallet design: the configuration permitted any single one of three authorized signers to approve transactions unilaterally. An attacker compromised one signer key, escalated their own permissions, removed legitimate signers, and minted approximately 8.35 million USDR and 4.5 million EURR — around $13.5 million in unbacked tokens at face value. After selling into limited secondary-market liquidity, the attacker realized roughly $2.8 million in actual proceeds before StablR could respond.

The incident created an immediate MiCA compliance breach: the outstanding supply of both tokens momentarily exceeded their fiat backing at the required 1:1 ratio. EURR's market price fell as low as $0.548; USDR stabilized near $0.994. At StablR's request, exchanges suspended trading, deposits, and withdrawals for both tokens.

StablR activated its formal Recovery Plan in accordance with EBA guidelines for MiCA-licensed crypto-asset issuers, notified the MFSA, and engaged external cybersecurity forensic specialists. The company confirmed that fiat reserves backing the tokens remained intact and unaffected throughout the incident, segregated in the accounts separate from operational funds.

As of July 2026, minting and redemption services remain suspended pending completion of the forensic investigation, resolution of the reserve deficit, and MFSA sign-off on resumed operations. The incident has become one of the first documented cases of a MiCA-licensed EMT issuer navigating a major operational crisis under the new regulatory framework — an early, unplanned stress test of how the EU's stablecoin rules function in practice.

Ecosystem Position

StablR entered the European stablecoin market at a pivotal moment, securing MiCA authorization during the regulation's initial implementation cycle and launching both a euro and a dollar EMT on Ethereum and Solana simultaneously. The Tether strategic investment added capital and infrastructure, while exchange listings across major venues provided liquidity that few comparable European EMTs had achieved at a similar stage.

The long-term standing of EURR and USDR in the Solana ecosystem will depend on StablR's ability to resolve the post-incident suspension, restore full backing compliance, and retain its MFSA electronic money licence — the foundation on which its entire regulated stablecoin model rests.
