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
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
