​
Quick Summary

c8ntinuum is a forward-compatible EVM chain. Your existing Solidity contracts, development tools, and workflows work without modification. The enhancements below are additions that don’t break any existing patterns.

What’s Unique to c8ntinuum

​
Precompile Categories

c8ntinuum exposes a curated set of precompiles that go far beyond standard Cosmos EVM: Interoperability & Verification
  • IBC light clients (ics02) and token transfers (ics20)
  • zkVM proof verification — SP1 Groth16/Plonk verifiers and Poseidon hash
  • Solana transaction parsing (solanatx) and Ed25519 signature verification
Advanced Cryptography
  • Post-quantum signatures: ML-DSA, SLH-DSA
  • Partial signatures: FROST
  • Multiple curves: Schnorr, Schnorrkel, P-256
On-Chain Utilities
  • Verifiable randomness (ecvrf)
  • JSON parsing (json)
  • Address compression (addresstable)
  • Bech32/EVM address bridging (bech32)
Cosmos Module Access
  • Bank, Staking, Distribution, Governance, Slashing
  • ERC-20 token surfaces
  • Custom validator rewards

​
Pre-deployed Contracts

c8ntinuum ships with widely-used ecosystem contracts at well-known addresses, removing the bootstrap tax: See Pre-deployed Contracts for the full list.

​
Dual Address System

Every account has two representations:

​
Dual Chain ID

  • Cosmos Chain ID (string): For consensus, IBC, and governance
  • EVM Chain ID (integer): 8 — for EIP-155 transaction signing and wallet configuration

​
Development Tools

Standard Ethereum tools connect through c8ntinuum’s EVM JSON-RPC endpoint:
