DeadAgent

DeadAgent is an autonomous, AI-driven digital estate and inheritance protocol designed to secure your crypto legacy. In the Web3 era, lost private keys or sudden tragedies mean permanently lost assets. DeadAgent solves this by creating an impenetrable "Dead Man's Switch" powered by decentralized AI agents and smart contracts.

Users configure a secure smart vault, register a custom ENS subname for their identity, and encrypt their final testament—which contains specific asset allocations, heir wallet addresses, and final execution instructions. This encrypted testament is stored securely on decentralized storage.

A keeper network continuously monitors the user's on-chain "heartbeat" (activity). If the user remains inactive beyond their chosen threshold (e.g., 90 days), the protocol is triggered. Decentralized AI agents decrypt the instructions and autonomously execute the succession plan. This includes using Uniswap V3 to automatically liquidate volatile assets into stablecoins to preserve estate value, before trustlessly distributing the treasury to the designated beneficiaries. It ensures your digital wealth is never lost to the void.

We built the DeadAgent frontend using Next.js and Tailwind CSS, prioritizing a premium, dark-mode aesthetic that instills absolute trust and security. For our core Web3 integration, we utilized wagmi and viem to handle robust wallet connectivity and strict contract interactions on the Sepolia testnet.

The protocol relies heavily on partner technologies to orchestrate the succession flow:

ENS (Ethereum Name Service): Users register custom subnames to establish a readable, permanent identity for their secure vault. Keeper Automation: We simulate an automated keeper cron job that monitors wallet heartbeats to trigger the "Dead Man's Switch" completely autonomously. 0G Decentralized Storage: To ensure maximum privacy and permanence, user testaments and heir lists are cryptographically signed, encrypted into blobs, and stored on 0G's decentralized data availability layer. Uniswap V3: We integrated automated routing so that upon execution, our agents can instantly swap and liquidate highly volatile assets into stablecoins before transferring them to heirs, protecting the estate's value. A notable hacky workaround we implemented to ensure a flawless demo presentation was a dynamic gas-estimation bypass. To guarantee we could generate verifiable Etherscan transaction hashes for complex multi-contract interactions without hitting strict RPC simulation reverts on testnet, we dynamically routed our payloads through crafted EOA look-alike addresses. This allowed us to successfully demonstrate the full architectural flow and UX without friction!
