Radiant Capital
HackedDeFi · born 2022 · ✝ 2024
A lending protocol re-hacked via compromised hardware wallets.
Radiant Capital was a cross-chain lending protocol on Arbitrum and BNB Chain. In October 2024 it lost ~$50M when attackers compromised multiple core-team hardware wallets — the same attack vector that hit WazirX months earlier.

☠️ Cause of death
Malware on signer devices and a deceptive UI let attackers push malicious contract upgrades through Radiant's multisig. The team took full accountability, unlike the custody finger-pointing seen elsewhere.
📓 Lessons left behind
- —Hardware wallets don't help if the screen lies.
- —Multisig teams are a single phishing campaign away from ruin.
- —DeFi 'decentralization' often hides a small signer set.
🌱 The idea that survived
Signer hygiene & timelocks
Protocols adopted mandatory timelocks, hardware isolation, and transaction-decoder tooling after the Radiant/WazirX pattern became undeniable.
