OpenGDP Network

OpenGDP is a fully EVM-compatible Layer 1 blockchain. All protocol extensions are additive; no existing EVM opcodes or execution semantics are modified.

Design Philosophy

Protocol features are delivered through two extension mechanisms:

Precompiles: Fixed-address contracts that implement protocol logic (fee management, orderbook, token factory, etc.) at native speed.
Transaction type extensions: New tx types (0x76 for AA, 0x4a for encrypted) that carry additional fields while remaining compatible with existing RPC infrastructure.

This means any Solidity/Vyper contract that compiles against a standard EVM target will deploy and execute on OpenGDP without modification.

Tooling Compatibility

Tool	Status	Notes
Foundry (`forge`, `cast`, `anvil`)	Supported	Standard deployment and testing workflows.
Hardhat / Ethers.js	Supported	Connect via JSON-RPC as with any EVM chain.
Viem / Wagmi	Supported	Custom transport for AA and encrypted tx types available in the OpenGDP SDK.
Block Explorers	Compatible	Standard receipt and log formats.

Example: Deploying a Contract

Deploying is identical to any EVM chain:

# Using Foundry
forge create src/MyContract.sol:MyContract \
  --rpc-url $OPENGDP_RPC \
  --private-key $DEPLOYER_KEY

The only difference from Ethereum Mainnet is that the deployer pays gas fees in a stablecoin rather than in a native token.
