From Source to Deployment with Tooling

Before your contract can live on VeChainThor, it must be turned into bytecode and an ABI.​
The solc compiler does this transformation:

solc Learn2Earn.sol \
  --evm-version shanghai \
  --optimize --optimize-runs 200 \
  --bin --bin-runtime --abi --hashes --metadata --asm \
  --overwrite -o

solc Learn2Earn.sol \
  --evm-version shanghai \
  --optimize --optimize-runs 200 \
  --bin --bin-runtime --abi --hashes --metadata --asm \
  --overwrite -o

solc Learn2Earn.sol \
  --evm-version shanghai \
  --optimize --optimize-runs 200 \
  --bin --bin-runtime --abi --hashes --metadata --asm \
  --overwrite -o

The result: a compiled bytecode blob and a JSON ABI that your frontend and SDKs use to interact with the contract.​

To avoid reinventing the wheel, you can import OpenZeppelin contracts—battle‑tested ERC‑20, ERC‑721, access‑control, and governance modules that work on VeChain because it is EVM‑compatible.​
You simply install them in your project, inherit the relevant contract, and configure Hardhat (or similar) to point at VeChain’s RPC endpoints.

Hardhat then becomes your central toolbox:

• Compile contracts.

• Run tests.

• Deploy to VeChain testnet or mainnet.​

Typical VeChainFlow: write Solidity → compile with solc/Hardhat → deploy with Hardhat scripts → interact via VeChain SDKs or VeChain Inspector.​
