Precompiles

| Precompile | Address | Purpose | |------------|---------|---------| | DASigners | 0x...1000 | Data availability signatures | | Wrapped0GBase | 0x...1002 | Wrapped 0G token operations |

Architecture

Modular design: consensus (CometBFT) separated from execution (EVM)
11,000 TPS per shard, sub-second finality
EVM-compatible (Pectra & Cancun-Deneb support)
VRF-based validator selection
Roadmap: DAG-based consensus, shared security model

Important Notes

Always use --evm-version cancun when compiling
0G Chain is fully EVM-compatible — existing Solidity code works without changes
Testnet faucet: 0.1 0G per wallet per day
