ZeroDev is a smart account abstraction platform for EVM-compatible blockchains that provides developers with an SDK and infrastructure layer built on ERC-4337 account abstraction standards. The platform abstracts key management, gas fees, transactions, and cross-chain operations to enable gasless and walletless user experiences. Core components include key abstraction for simplified credential management, gas abstraction to eliminate native token requirements for transaction fees, transaction abstraction for flexible execution models, chain abstraction for multi-chain interactions, and smart routing addresses for optimized account addressing. The system functions as developer tooling and infrastructure rather than a consumer-facing wallet or protocol, allowing application builders to reduce user friction by removing the need for private key management or gas token holdings. ZeroDev is developed by Offchain Labs.

ZERT is a cryptocurrency Decentralized Finance (DeFi) system engineered on the principle of trustlessness, aiming to provide a secure environment where users maintain full, autonomous control over their digital assets. The platform distinguishes itself by not requiring users to rely on a third-party intermediary, aligning with the core ethos of decentralized technology. By integrating advanced security protocols and a unified solution architecture, ZERT strives to guarantee the perpetual safety and sovereignty of its users' cryptocurrency holdings. This focus on non-custodial control is central to the platform’s value proposition, ensuring that users have exclusive access to and management of their funds at all times. ZERT's system is therefore positioned to offer a single, reliable point of access for all necessary DeFi functions while rigorously maintaining user security and independence.

Zone21.com is a comparison and risk-assessment platform for Bitcoin-backed lending providers.

Risk assessments are based on custody models, rehypothecation practices, loan-to-value (LTV) ratios, and know-your-customer (KYC) requirements. The platform covers multiple lending providers and presents comparative data including interest rate ranges, liquidation thresholds, and accepted collateral types in structured tables. Users can customize comparisons between providers. The platform generates and publishes provider rankings.
