Altitude Wallet
Your assets. Your keys. Your control.
Altitude Wallet is a non-custodial browser extension wallet for EVM-compatible blockchains. It gives you full ownership of your crypto — no accounts, no custodians, no middlemen. Your private keys are encrypted on your device and never shared with anyone.
Why Altitude Wallet
- Non-custodial — Only you hold your private keys. No third party can access, freeze, or seize your funds
- Multi-chain — Manage assets across Ethereum, Arbitrum, Optimism, Base, Polygon, BNB Chain, Avalanche, and more from a single interface
- Built for security — Every transaction requires your explicit confirmation. Keys are decrypted only at the moment of signing and cleared from memory immediately after
- Transparent by design — Built on open standards (BIP-39, EIP-1559) with a modern, auditable codebase
What You Can Do
- Create or import wallets and manage multiple accounts across chains
- Send tokens with automatic gas estimation and a confirmation step before anything is signed
- View real-time balances, price charts, and full transaction history
- Audit and revoke token approvals granted to DeFi protocols
- Lock your wallet at any time — keys are wiped from memory instantly
