Compatibility Matrix

The matrix reflects the current c8ntinuum documentation status. For production wallet policy or protocol compatibility gates, verify EIP-7702 support, precompile behavior, gas formulas, and node release version against the target network.

​
Forward Compatibility

c8ntinuum is forward-compatible with Ethereum:
  • It can run any valid smart contract from Ethereum
  • It can implement features not yet available on standard Ethereum EVM (zk verification, post-quantum signatures, Solana interop)

​
What’s Enhanced

​
Additional Precompiles

Beyond standard Ethereum precompiles (ecrecover, sha256, etc.), c8ntinuum provides:
  • Cross-chain: IBC light clients, ICS-20 transfers, Solana tx parsing, SP1 zk proof verification
  • Cryptography: Ed25519, P-256, Schnorr, Schnorrkel, FROST, ML-DSA, SLH-DSA, VRF
  • Hashing: SHA-3, BLAKE2b, Poseidon, gnark-crypto aligned hashes
  • Cosmos modules: Bank, Staking, Distribution, Governance, Slashing, ERC-20
See Modules for the full catalogue.

​
Pre-deployed Contracts

12 widely-used contracts deployed at genesis (Multicall3, Permit2, WETH9, Safe, CreateX, etc.). See Pre-deployed Contracts.

​
Base Fee Burn

c8ntinuum follows EIP-1559-style base-fee behavior: the base fee is burned, while priority fees are paid according to the chain’s EVM fee-market logic. See Gas on c8ntinuum for configured fee-market parameters.

JSON-RPC Notes

  • Public endpoint method coverage is provider-dependent; see RPC Reference
  • Mining-related methods return stub values (CometBFT consensus)
  • txpool_* methods require compatible node configuration
  • Debug tracing is intended for full archive debug surfaces, not the default public RPC
