Pumper Wallet

A wallet that reads every transaction and signature before you sign it, and blocks drainers.

Pumper Wallet is a self-custody wallet for the Stable network (and Base) built around one job: making sure you know exactly what you sign. Before any transaction or signature reaches your keys, Pumper Wallet: - Simulates it and shows what you give and what you get - Decodes approvals, permits, Permit2, marketplace orders, batches and smart-account delegations - Explains the risk in plain words and blocks known drainer patterns: unlimited approvals to unknown wallets, free NFT listings, blind signatures, hidden approvals and account takeovers - Warns about look-alike addresses (address poisoning) and look-alike websites - Recognises every official Pumper contract, and lets you trust contracts of apps you use Security - Keys are encrypted on your device with your password (scrypt + AES-256-GCM) - Optional two-factor authentication: your wallet can only be decrypted with your password AND a code from your authenticator app, so a copied wallet file and a stolen password are not enough - Codes are also required for sensitive actions: exporting a key, sending to a new address, approving unknown spenders - Auto-lock, and Ledger hardware wallet support Wallet - Balances and USD value of all your tokens - Staked, locked and liquidity positions - Send to addresses, .stable names or contacts - Receive with QR code - Transaction history - Address book Built on Stable. Pumper never sees your keys or recovery phrase.
