Nexus by Biconomy: ERC-7579 Modular Smart Account for Enhanced Account Abstraction
Anonymous Multi-Sig Smart Account Module
ERC-4337 smart contract wallet focused on UX and security: passkeys, account abstraction, modular architecture, and on-chain social recovery.
ERC-4337 utilities for sending user operations with ethers.js
AgentPay — high-frequency agent-to-agent settlement layer on Monad. x402 + ERC-7579 modular accounts cut AI billing costs ~96% with 0.8s finality and session-sharded parallelism for 10,000+ concurrent payments.
A modular ERC-7579 smart account (ERC-4337) secured by passkeys (WebAuthn), with pluggable validator, executor, fallback, and hook modules — open for anyone to build and contribute their own.
zkML-powered liquidation protection for Aave V3 using Halo2, EZKL, and ERC-7579 smart accounts.
Quantum-safe treasury accounts for Arbitrum: NIST post-quantum signatures verified by Stylus, a capped classical hot key, and an on-chain Q-Day tripwire.
A payment address on Robinhood Chain that invests part of every payment. USDG arrives, your rule splits it, and the equity share buys Stock Tokens into your own smart account. Every split writes a receipt anyone can recompute.
Wallet safety & scheduled transfers on Safe (ERC-7579). Built at ETHGlobal Brussels 2024.
Subscription Permissions Standard for Monad — draft MIP and Foundry reference implementation
Open infrastructure for onchain agent accounts, authorization and payments.
Modular ERC-4337 v0.8 / ERC-7579 smart account built from first principles with Foundry — a learning and portfolio project
ERC-7579 hook module: a fail-closed on-chain pre-execution gate that admits a smart-account call only if an independent, recomputable invinoveritas /review verdict binds (by on-chain recompute) to that exact action.
Zero custody AI firewall for autonomous trading agents. ERC-7579 module with ERC-7715 session keys (SmartSessions). Agents get scoped on-chain ETH budgets and session keys, never private keys. Every trade intent is forensically audited by a Chainlink CRE oracle running dual-model AI consensus (GPT-4o + Llama-3) before capital moves.
Biconomy — independent third-party profile of a public API surface, by API Evangelist. Biconomy's open-source ERC-4337 TypeScript Bundler. Implements eth_sendUserOperation, eth_estimateUserOperationGas, eth_getUserOperationByHash, eth_getUserOperationReceipt, and eth_supportedEntryPoints across both EntryPoint v0.6.0 and v0.7.0.
