Subspace EVM Contracts

This repository contains the relevant EVM Contracts that are deployed on Subspace Nova. This could perhaps be considered as a one-stop shop for all the relevant contracts, libraries deployed on Subspace Nova.

Currently, the contracts are deployed on the gemini-3g Nova chain with chain ID 1002.

Usage

Smart Contracts

Build

forge build

Test

Gas Snapshots

forge snapshot

• 1 TSSC = 1e9 Gwei
• Block gas limit = 60,000,000

Example of converting gas usage to TSSC:

gas price = 3.00000002 Gwei
So, 27,177,138 gas would cost:
27,177,138 * 3.00000002 Gwei = 81,531,414.54354276 Gwei * 10^-9 = 0.08153141454354276 TSSC

Deploy

forge script script/Counter.s.sol:CounterScript --rpc-url <your_rpc_url> --private-key <your_private_key>

Generating Rust bindings to the contracts

Before following this, make sure you have the forge CLI installed.

Rust bindings to the contracts can be generated via forge bind, which requires first building your contracts:

# Build the contracts
$ forge build --root ./bindings
# Generate the bindings to the contracts
$ forge bind --bindings-path ./bindings --root ./ --crate-name subspace-evm-bindings

Any follow-on calls to forge bind will check that the generated bindings match the ones under the build files. If you want to re-generate your bindings, pass the --overwrite flag to your forge bind command.
