c8ntinuum supports standard EVM bytecode execution, including all standard opcodes. For application developers, opcode-level behavior should be treated as Ethereum-compatible unless a c8ntinuum-specific page documents an exception. Use eth_estimateGas against the target network before submitting production transactions.

​
EVM opcodes

AreaGuidance
Standard opcodesUse normal Ethereum tooling and gas estimates; no c8ntinuum-specific opcode repricing is documented here.
Contract sizec8ntinuum’s maximum contract size is configurable. See Differences from Ethereum.
Gas estimationUse eth_estimateGas and test the final transaction path before submitting.
Pre-deployed contractsExecute as ordinary EVM bytecode with ordinary EVM gas accounting; see Pre-deployed Contracts.

Precompile costs

c8ntinuum adds native precompile surfaces beyond the standard Ethereum set. Source-backed formulas are summarized in Precompile ABI Reference.
Precompile classCurrent documented pricing
Stateful Cosmos module transactions2000 + 30 * input bytes, then SDK execution is metered inside the call
