What is XDEFI Wallet?
XDEFI Wallet was a self-custodial, multichain cryptocurrency wallet built as a browser extension. It enabled users to store, transfer, and swap digital assets across non-EVM and EVM ecosystems, supporting over 2,500 networks and 10,000 tokens before it rebranded to Ctrl Wallet and ceased operations.
Team and background
Founded in 2020 in London, United Kingdom, XDEFI Wallet was led by chief executive officer Emile Dubié. The project developed non-custodial wallet infrastructure aimed at unifying fragmented blockchain networks into a single interface. In April 2026, Cardano commercial arm EMURGO acquired the underlying technology infrastructure of Ctrl Wallet, leaving the CTRL token out of the transaction.
Network connectivity and mechanics
The application was an externally owned account (EOA) wallet where users held their own private keys and seed phrases. Onboarding required no identity verification. The wallet supported major chains including Bitcoin, Ethereum, THORChain, Avalanche, Arbitrum, Polygon, Dogecoin, Litecoin, and BNB Smart Chain. Cross-chain trading was handled through integrations such as THORChain, executing decentralized swaps without additional wallet markups.
Audits and security shutdown
Kudelski Security audited the wallet codebase in July 2021, and the team made the client extension source code public under the Apache-2.0 license. The wallet had approximately 650,000 monthly active users. Between June 21 and June 23, 2026, a cryptographic exploit hit the Cardano integration layer on shared EMURGO infrastructure, resulting in the theft of 16.1 million ADA. Because the vulnerability compromised core shared systems, operations permanently ceased on August 3, 2026.
Current status and risks
Active wallet services are offline. Users cannot send funds, receive assets, swap tokens, or connect to decentralized applications through the software. The only functional feature remaining is recovery-phrase export. Former users can retrieve their seed phrases and migrate funds to other self-custodial wallets.

Our review
2.7/5
Weak
XDEFI Wallet offered broad multichain connectivity and native THORChain swaps, but permanently ceased operations in August 2026 following a security exploit on shared infrastructure.
XDEFI Wallet, founded in London in 2020 by Emile Dubié and later rebranded as Ctrl Wallet in July 2024, operated as a self-custodial browser extension and mobile wallet. At its peak, the platform served roughly 650,000 monthly active users and supported over 2,500 blockchain networks. The extension connected directly to decentralized applications across Bitcoin, Ethereum, Avalanche, Arbitrum, Polygon, BNB Chain, and THORChain.
Key strengths included broad asset coverage and integrated trading. NFTs from distinct ecosystems appeared in a unified gallery, while native THORChain swaps were available without supplemental wallet fees. The client codebase was made available under the Apache-2.0 open-source license, and Kudelski Security completed an audit in July 2021.
- In June 2026, a cryptographic exploit hit Cardano infrastructure managed by parent company EMURGO, which acquired Ctrl Wallet's core tech stack earlier that year, draining roughly 16.1 million ADA.
- Operations ceased permanently on August 3, 2026, disabling transfers, network connectivity, swaps, and dApp integrations.
- The application was subsequently removed from app stores.
Users who previously stored funds in XDEFI or Ctrl Wallet can no longer conduct transactions within the interface and must export their recovery phrases into alternative non-custodial software such as MetaMask or Phantom. The wallet can no longer be used for active trading or transfers.
