Quantum-Safe from Day One
The first EVM-compatible blockchain with native post-quantum cryptography. No migration. No compromise.
Built for the Post-Quantum Era
Every layer — from cryptography to consensus — engineered for a quantum-computing future.
Post-Quantum Signatures
CRYSTALS-Dilithium (ML-DSA) as default, SPHINCS+ as conservative fallback. NIST Level 3 standard — quantum-resistant from day one.
Learn moreEVM Compatible
Cancun-spec EVM. Run your Solidity contracts with Hardhat, ethers.js, and MetaMask — zero migration cost.
Learn moreNative Account Abstraction
Protocol-level smart accounts with 3-layer validation, pq1... Bech32m addresses, key rotation without address changes, and custom validator hooks — no ERC-4337 bundler needed.
Learn morePQ Precompiles
On-chain Dilithium/SPHINCS+ verification, Kyber decapsulation, and STARK proof verification as native precompiles.
Learn morePoA Consensus
Epoch-based Proof-of-Authority with dynamic validator management, finality tracking, and planned decentralization path.
Learn moreFull JSON-RPC
Complete Ethereum-compatible API (eth_*, web3_*, net_*, debug_*) plus Shell-specific endpoints for node and network stats.
Learn moreNative Account Abstraction
Every account is a smart account from day one — post-quantum signatures validated at the protocol layer, not through an overlay contract.
Three-Layer Validation Flow
First-Use Validation
Derive address from (version, algo_id, pubkey) via BLAKE3 and verify PQ signature — account created on first transaction.
Default PQ Validation
Existing accounts verify pubkey_hash + PQ signature. Key rotation changes the key but keeps the same address.
Custom Validator
Delegate validation to account-specific EVM logic — multisig, social recovery, time locks, or any custom policy.
No Bundler Required
Validation is part of the base protocol — no ERC-4337 EntryPoint or separate alt-mempool.
pq1... Addresses
Bech32m encoding with PQ HRP — visually distinct from Ethereum, binds to the signing algorithm.
Key Rotation
Rotate keypair or switch PQ algorithm — your on-chain address and identity stay the same.
Custom Validators
Multisig, social recovery, time locks — deploy your own validation logic as an EVM contract.

Why Shell Chain?
A side-by-side look at how Shell Chain compares to existing blockchains.
| Dimension | Bitcoin | Ethereum | Shell Chain ✦ |
|---|---|---|---|
| Cryptographic Security | ECDSA (vulnerable to quantum) | ECDSA (vulnerable to quantum) | ML-DSA (Dilithium3) — NIST post-quantum standard |
| Account Abstraction | None | ERC-4337 overlay (bundler required) | Native protocol-level AA — no bundler needed |
| Smart Contracts | None (basic Script only) | Full EVM support | Full EVM (Cancun-spec) — zero-cost migration |
| Consensus | PoW (high energy, mining pools) | PoS (stake centralization) | Pluggable PoA → planned decentralization |
| Storage | UTXO slow indexing | LevelDB / MPT hybrid | Custom RocksDB — multi-CF read/write isolation |
