Foundry

Foundry 1.8.5 is the reference toolchain for this documentation: every Getting Started journey is executed with it.

curl -L https://foundry.paradigm.xyz | bash
foundryup --install 1.8.5
forge --version      # forge Version: 1.8.5
foundry.toml
[profile.default]
src = "src"
out = "out"
libs = ["lib"]
solc_version = "0.8.26"     # pinned; matches contracts/studio/compilers.json
evm_version = "cancun"      # chain 77240 runs PUSH0/MCOPY/TSTORE; never use blobhash()/blobbasefee
optimizer = true
optimizer_runs = 200
bytecode_hash = "none"      # no metadata hash: deterministic runtime bytes for byte-for-byte verification
remappings = ["@openzeppelin/contracts/=lib/openzeppelin-contracts/contracts/"]
Task Command
Chain check cast chain-id --rpc-url "$RPC" → 77240
Account cast wallet new keystore dev -p
Balance cast balance <addr> --ether --rpc-url "$RPC"
Send cast send <to> --value 0.01ether --keystore … --password-file … --rpc-url "$RPC"
Deploy forge create src/C.sol:C --broadcast --keystore … --password-file … --rpc-url "$RPC" --constructor-args … (constructor args last)
Raw bytecode deploy cast send --async <wallet opts> --create 0x<bytecode> (options before --create)
Call cast call <addr> "get()(uint256)" --rpc-url "$RPC"
PQWERAI finality cast rpc g4_status --rpc-url "$RPC"
Logs cast logs --from-block N --to-block M --address <addr> "Event(...)" (≤ 5000 blocks)

Notes from testing:

  • cast receipt <tx> status prints true/false.
  • forge lint warnings (e.g. reentrancy-events) are advisory; the tutorials are written to avoid them.
  • Offline builds: FOUNDRY_OFFLINE=true FOUNDRY_SOLC=/path/to/solc-0.8.26.
  • forge script --broadcast works like on any EVM chain; set --chain-id 77240 if you sign offline.
