Web3 & Blockchain DDoS Protection

Full-chain protection for nodes, RPCs and bridges. A stability-first plan built for decentralized infrastructure.

Why Web3 infrastructure is a prime target

Decentralized infrastructure has three traits that make it a high-value DDoS target:

  • Publicly exposed RPC ports—most nodes serve RPC openly, so attackers can overwhelm them with concurrent requests without any intrusion, taking every dApp down with them.
  • Offline validators get slashed—if a PoS validator drops due to a network outage, the protocol slashes it. A DDoS therefore becomes a direct economic attack.
  • Bridges are a single point of failure—bridge contracts depend on a few relay nodes; knock them out and cross-chain assets freeze, far beyond a single chain.

The attacks Web3 services face most

Attack typeMethodConsequence
RPC FloodMass concurrent requests saturate node RPCNode stops responding, dApps and wallets go down
Direct node IP hitBypass front protection, hit origin IPValidator offline and slashed
Mempool spamLow-cost junk transactions flood the mempoolLegitimate transactions can't get packed
Bridge relay attackVolumetric hits on bridge relay nodesCross-chain assets frozen, bridge offline

AwayDDoS Web3 protection plan

1. RPC gateway scrubbing

All RPC requests pass through protection nodes first; rate limiting and behavior fingerprints precisely filter malicious requests while normal calls and block queries stay unaffected.

2. Validator IP concealment

Nodes only accept traffic from scrubbing-center IPs; the origin IP is never exposed, so attackers cannot bypass the front line and hit it directly—eliminating the slashing risk at its root.

3. Mempool and transaction rate limiting

Transaction broadcasts are checked against frequency and signature baselines; junk and duplicate submissions are dropped so legitimate transactions get packed in time.

4. L2 and cross-chain bridge protection

Rollup sequencers and cross-chain relay nodes get tunnel protection, preventing a single point of failure from freezing assets and keeping cross-chain services continuously available.

Why Web3 teams choose us

  • Low-latency origin routing—block finality is latency-sensitive; intelligent routing keeps node sync fast and avoids missed blocks.
  • Non-standard ports and P2P supported—full coverage of node P2P and RPC protocols, not limited to HTTP.
  • Never blackhole—we don't shut down your nodes during attacks, so on-chain services stay up. See What Is DDoS Blackholing?
  • 7×24 expert operations—when an attack hits at 3 a.m., someone is on it with you.
  • Flat pricing—a bill that grows with how hard you're hit is unacceptable for blockchain businesses too.

Recommended deployment

Most Web3 teams combine DNS diversion at the entry point + GRE/BGP tunnels to protect core nodes and cross-chain relays: the former takes effect in minutes with zero ops, the latter brings the whole subnet under protection. Full comparison of the three modes is in Protection Solution.
