​
Compatibility Matrix

The matrix reflects the current c8ntinuum documentation status. For production wallet policy or protocol compatibility gates, verify 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 Ethereum smart contract that targets the Prague EVM version or earlier. Compile with evmVersion set to prague or lower.
  • It can implement features not yet available on standard Ethereum EVM (zk verification, post-quantum signatures)

​
What’s Enhanced

​
Additional Precompiles

Beyond standard Ethereum precompiles (ecrecover, sha256, etc.), c8ntinuum provides:
  • Cross-chain: IBC light clients, ICS-20 transfers, 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

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

​
Fee Burn

c8ntinuum follows EIP-1559-style fee behavior but burns the whole fee: the base fee and the priority fee are both burned by x/feeburn, so validators receive no fee revenue. The priority fee still sets transaction priority. 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 (eth_mining, eth_hashrate, eth_coinbase, eth_getWork, eth_submitWork, eth_submitHashrate) are not available and return JSON-RPC error -32601 (CometBFT consensus, no mining)
  • txpool_* methods require compatible node configuration
  • Debug tracing is intended for full archive debug surfaces, not the default public RPC
