This Bash script calculates the Safe transaction hashes by retrieving transaction details from the Safe transaction service API and computing both the domain and message hashes using the EIP-712 standard.
Multi Meta Transaction on Ethereum with EIP-712 and ERC-2612 Standards
The node module that allows you to control your Ethereum revocation lists & resolve revocation keys.
Reference ERC7518 security token
Privacy-preserving payment protocol. Deposit/claim pool with SBT-gated access, per-transaction EIP-712 fee attestation, and stateless redemption. AGPL-3.0.
Verifiable financial statements from Ethereum wallets. Cryptographically signed. Instantly verifiable. No backend.
Security proxy for AI agents (OpenClaw, LangChain, CrewAI). Protects API keys, enforces spend limits, blocks dangerous endpoints. Local-first Rust binary — your credentials never leave your machine.
Decentralized governance system with proposal lifecycle, three-way voting, checkpoint-based delegation and timelock execution delay
MIT-licensed ERC-20 with no admin mint path. Every claim requires a valid SBT, an advanced activity nonce, and an EIP-712 signature over a cumulative amount. Reference implementation immutably deployed on Arbitrum One.
Decentralized NFT marketplace with EIP-712 signed listings, royalty support and platform fees
A decentralized application demonstrating gas optimization through transaction batching, EIP-712 meta-transactions, and sponsorship pools on Sepolia testnet.
Single-page developer reference: endpoints, contract addresses, order struct, EIP-712, V1 to V2 migration, fees, SDK packages
Hardware-backed Android wallet for x402 payments. Generates secp256k1 seeds on-device, wraps them with a StrongBox-resident AES key, signs transferWithAuthorization per biometric tap, settles USDC on Base Sepolia. Four-step build from Node hello-world to a Pixel app, with companion notes on passkey + smart-wallet evolution.
Pk-less (external-signer) Python reference for Polymarket CLOB V2 — TypedDataSign builder + EIP-7912 augmentation + L2 HMAC. Targets mobile/hardware/smart-contract wallet flows that never custody an EOA private key.
Minimal Python reference for placing orders on Polymarket CLOB V2. Shows EIP-712 signing, order struct, pUSD wrap.
A Solidity implementation of a token airdrop system using Merkle trees for efficient and gas-optimized token distribution.
Intent-Based Sovereign Smart Account — ERC-4337 + 4-layer defense + 126 tests | No blind signing. No long-lived keys. Recoverable identity.
