Web3 and Decentralised Application (dApp) Security Testing for Singapore Enterprises

Decentralised applications combine multiple security domains: smart contract security (the immutable on-chain logic — vulnerabilities cannot be patched after deployment), frontend application security (the web interface users interact with), wallet integration security (how the application interacts with user wallets), oracle security (external data feeds that smart contracts depend on), and bridge security (cross-chain communication). Testing must cover the full stack because attacks often exploit the interaction between layers — a secure smart contract can still be exploited through a compromised frontend.
