Smart Contracts & Protocol Protection

styled_divider

Comprehensive blockchain security solutions covering smart contracts, protocols, wallets & exchanges. Prevent exploits & build trust.

Credshieds has extensive experience researching the security of public blockchains such as Bitcoins, Ethereum, Cosmos, and others and has a deep understanding of the security of crucial modules like P2P communication, node security, RPC calls, cryptography, consensus mechanisms, and asset transactions.

Why It Matters

  • $3B+ lost in blockchain exploits in 2023
  • One compromised wallet or bridge can affect the entire ecosystem
  • Exchanges and protocols must meet compliance standards for listings

Our Process

  • Threat modeling of entire blockchain stack
  • Smart contract audits (ERC & custom tokens)
  • Wallet & bridge security validation
  • Governance & DAO security reviews
  • Economic exploit simulations
  • Final audit & certification

Case Study

A cross-chain DeFi project with $1B+ in liquidity relied on CredShields for blockchain security. We discovered flaws in bridge logic that could have led to double-spending, patched pre-launch, preventing catastrophic loss.
