HEIR - Estate Guardian

Self-custody multi-chain wallet and Estate Guardian: web3 on 182 chains, proof-of-life monitoring, and one-click estate check-ins.

HEIR is a self-custody crypto wallet that is also your inheritance guardian. NEW IN THIS VERSION - Dock the wallet into Chrome's side panel and keep it open beside whatever you are doing — balances, approvals and estate check-ins stay visible while you use a dapp, instead of vanishing every time you click away. The toolbar popup still works exactly as before; the side panel is one click from it. - Refreshed look, matching heir.es. WALLET - Create or import a wallet from a BIP-39 recovery phrase. Your keys are generated in your browser and encrypted on your device with AES-256-GCM under a PBKDF2-SHA-256 key (600,000 iterations). HEIR's servers never receive your recovery phrase or private keys. - Connect to dapps like any wallet: HEIR announces a standard Ethereum provider (EIP-1193 / EIP-6963) and a Solana Wallet Standard provider, so it appears in connect dialogs automatically without fighting other wallets. - 182 EVM chains with automatic RPC failover — when an endpoint is unreachable the next one is tried, so there is no manual RPC setup for the networks HEIR already knows. - Send and receive the native coin and ERC-20 tokens, and add any token by address. Your Solana accounts are derived from the same recovery phrase and can sign and send through connected dapps. - Review every signature and transaction before you approve it, and manage which sites are connected. - Export your recovery phrase, root extended private key (xprv) and per-account private keys whenever you want, to import into another wallet. You are never locked in. ESTATE GUARDIAN - One-click check-in: if you have deployed an on-chain inheritance estate with HEIR, the wallet resets its dead-man's-switch timer and shows a countdown to your next deadline. The reset is a real on-chain transaction that you approve. - Deadline reminders: notifications as a check-in deadline approaches, so a missed deadline is a decision rather than an accident. - Inheritance view: see the estates you are named a beneficiary of, and claim on-chain once a claim becomes available. - Activity signal: HEIR can record that your extension is active to your HEIR account. This is activity telemetry — on its own it does not prove you are alive, and no inheritance decision is made from it. SECURITY - Self-custody: no HEIR-held key can decrypt your secrets. - The wallet locks when you restart your browser, and again after a period of inactivity (30 minutes by default, configurable). - Per-site permissions, and blind signing is refused — eth_sign and eth_signTransaction are rejected outright, so you are never asked to approve an opaque payload. - No remotely hosted code. Everything runs from the reviewed package. HEIR is free to install. The wallet works on its own; an optional HEIR account connects the Estate Guardian features to your estate plan.
