Signal hints at or exits Canada, refusing to cooperate with the new surveillance bill

The encrypted messaging app Signal stated that if Canada's Bill C-22 is officially passed and requires platforms to establish "lawful access" monitoring capabilities, the company may choose to exit the Canadian market rather than weaken end-to-end encryption. Signal's Vice President of Strategy and Global Affairs, Udbhav Tiwari, indicated that the bill could force communication services to create technical backdoors, thereby undermining encryption security and making private communications more susceptible to exploitation by hackers and foreign attackers.Bill C-22 was introduced in March 2026 as part of a new round of regulatory measures in Canada, requiring electronic service providers to establish law enforcement monitoring capabilities and retain certain user metadata for up to a year to assist in investigations of crimes such as terrorism and child exploitation. Critics argue that the bill is similar to the EU's previously controversial "chat monitoring" proposal, which could threaten end-to-end encryption and user privacy. Canadian Conservative MP Jacob Mantle stated that nearly all Canadian MPs use Signal precisely because of its privacy and security features, yet the bill could grant the government the ability to read private messages.Tiwari stated, "Signal would rather exit Canada than violate the privacy commitments made to users." In addition to Signal, the VPN provider Windscribe also indicated that if the bill passes in its current form, the company may follow Signal in withdrawing from the Canadian market. Windscribe claimed that the bill could force VPN services to log data that could identify users, violating its core privacy principles.

first_img The Ethereum Foundation launches the Clear Signing open standard to promote the readability of transaction signatures

The Ethereum Foundation officially launched the Clear Signing open standard on Tuesday, aimed at replacing the unreadable hexadecimal strings displayed when wallet users sign transactions with human-readable transaction content.This standard is centered around ERC-7730. When a wallet supports this standard, it will read the descriptor file of the contract and reconstruct the raw transaction data into understandable content, such as displaying a Uniswap V3 swap as sending 1,000 USDC and receiving at least 0.42 WETH. ERC-8176 adds an integrity certification layer on top of this, allowing auditors to publish signature certification confirming the accuracy of the descriptors. Participants include hardware wallets (Ledger, Trezor), software wallets (MetaMask, WalletConnect), security companies (Cyfrin), and infrastructure (Fireblocks), among others.Blind signing has been a significant cause of losses in crypto assets. The $1.5 billion vulnerability at Bybit in February 2025 and the approximately $235 million WazirX incident both involved signers approving transactions that did not reflect the true intent. Ledger initiated this project in 2021, formalized it as ERC-7730 in 2024, and transferred governance to the foundation earlier this year to ensure the neutrality of the standard. The ERC-7730 V2, released in April 2026, has expanded its coverage to cross-chain use cases, software wallets, and confidential token primitives.
