Overview

Stelo Labs builds security tools for crypto wallets — transaction simulation, approval monitoring, and developer APIs that help users understand and block risky signatures before they confirm on-chain. In February 2023, a16z's crypto fund led a $6M seed with First Round, Box Group, and Pear VC participating. Stelo reported protecting more than $100M in wallet value through its browser extension and integrations. The product targets both retail users and wallets embedding Stelo's API for safer signing flows.

Competitive landscape

Edge: Focus on pre-sign simulation and approval hygiene — the exact failure mode in 2022–2024 wallet drain campaigns.

Wallet security is arms-race driven; Stelo must keep pace with new drainer contracts and wallet SDK bundling similar features for free.

  • WalletGuard / ScamSniffer direct

    Browser extensions for scam detection; varying coverage.

  • Fire (formerly Blockaid) direct

    Transaction security API for wallets and dApps.

  • MetaMask built-in alerts incumbent

    Wallet-native warnings; Stelo adds deeper simulation.

Notable stories

  • Stelo raised right after the wallet-drainer epidemic peaked — a16z crypto bet users would pay attention at the signing moment, not after funds were gone (TechCrunch, 2023).
