gm

Active17

Terminal Ethereum Wallet for Developers

A TUI-based Ethereum wallet built for developers who live in the terminal. gm provides secure key management, dapp connectivity, and blockchain operations without ever leaving your command line.

Key Features

  • •Secure key storage via Apple Keychain (more backends in progress)
  • •WalletConnect integration — connect to dapps from the terminal
  • •Trustless data verification powered by Helios light client
  • •EIP-1193 provider — no more private keys in .env files
  • •Address book with Blockscout API integration

Proof of Exploit

Archived43

Zero-Knowledge Bug Bounty Proofs

Proof of Exploit enabled security researchers to prove knowledge of smart contract vulnerabilities without revealing the actual bug. Using zero-knowledge proofs built on zkEVM circuits, researchers could demonstrate that an exploit works and share cryptographic proof with bug bounty managers — all without disclosing vulnerability details.

Development discontinued — a core dependency (PSE/zkevm-circuits) is no longer maintained. Previously supported by Privacy and Scaling Explorations (PSE).

Key Features

  • •Write exploit, generate ZK proof, share without revealing the bug
  • •Challenge contract codehash revealed in public inputs; exploit contract stays hidden
  • •CLI with commands: exploit test, exploit prove, exploit verify
  • •Web-based proof verification at proofofexploit (verifier compiled to WASM)
  • •Proof storage via IPFS CIDs

Sleep Fine

Active

Blockchain-Backed Sleep Accountability

An accountability app that incentivizes better sleep habits. Users lock funds in a smart contract as a commitment to sleep on time — miss your target and funds are automatically deducted. Apple Watch integration pulls sleep data directly from HealthKit, with Secure Enclave key generation for data security.

Key Features

  • •Apple Watch integration with HealthKit for sleep tracking
  • •Smart contract-based commitment with automatic penalties
  • •Secure Enclave key generation for data security
  • •AI-powered validator selection via Mech agent

Ultralane

Archived2

Ultrafast Cross-Chain Private Payments

Ultralane enables ultrafast cross-chain private payments by holding advance deposits and using an optimistic approach with create2-based stealth addresses. It abstracts multiple networks into a single token balance, eliminates bridge confirmation delays, and allows privacy-conscious users to transact while peers use standard wallets.

Key Features

  • •Ultrafast payments via advance deposit locking — no bridge delays
  • •Cross-chain abstraction — single balance across multiple networks
  • •Privacy via zero-knowledge proofs with create2-based stealth addresses
  • •Non-custodial — trustless withdrawals at any time
  • •ZK proving optimized from 50s to 7s using Noir's Poseidon2
