Deploy Contracts

Deploy smart contracts to Helix Chain using Foundry.

Bash

curl -L https://foundry.paradigm.xyz | bash
foundryup

# Deploy a contract
# IMPORTANT: Must use --legacy flag (EIP-1559 not supported)
forge create src/MyContract.sol:MyContract \
  --rpc-url https://rpc.thehelixchain.xyz \
  --private-key YOUR_PRIVATE_KEY \
  --legacy \
  --gas-price 1000000000 \
  --broadcast

Warning: EIP-1559 (type 2) transactions are NOT included in blocks. Always use --legacy flag and explicit --gas-price 1000000000.
