Where to find opcode and precompile cost behavior for c8ntinuum applications.
CLZ (EIP-7939) are invalid; see Differences from Ethereum. 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.
| Area | Guidance |
|---|---|
| Standard opcodes | Use normal Ethereum tooling and gas estimates; no c8ntinuum-specific opcode repricing is documented here. |
| Contract size | Fixed at the Ethereum limits: 24,576 bytes of deployed code (EIP-170) and 49,152 bytes of initcode (EIP-3860). See Differences from Ethereum. |
| Gas estimation | Use eth_estimateGas and test the final transaction path before submitting. |
| Pre-deployed contracts | Execute as ordinary EVM bytecode with ordinary EVM gas accounting; see Pre-deployed Contracts. |
| Precompile class | Current documented pricing |
|---|---|
| Stateful Cosmos module transactions | 2000 + 30 * input bytes, then SDK execution is metered inside the call |
| Stateful Cosmos module queries | 1000 + 3 * input bytes, then SDK execution is metered inside the call |
SP1 Groth16 verifyProof | 300000 + ceil((publicValuesBytes + proofBytes) / 32) * 16 |
SP1 Plonk verifyProof | 800000 + ceil((publicValuesBytes + proofBytes) / 32) * 16 |
| Variable-length stateless precompiles | base gas + ceil(input bytes / 32) * word gas; use the relevant ABI/source entry for constants |
| P256 | Raw-call precompile; validate packed input shape in caller code |
