feat: add --gas override flag to deploy and write by ygd58 · Pull Request #404 · genlayerlabs/genlayer-cli

ygd58 · 2026-08-07T11:32:29Z

Summary

Fixes the CLI-side half of #402: no way to override gas estimation for deploy/write.

On Bradbury, genlayer write used the exact eth_estimateGas result as the outer EVM gas limit for addTransaction. The outer transaction reverted twice before GenVM was ever reached; identical calldata succeeded when replayed with a larger explicit gas limit (1,319,997 estimated & reverted twice; 2,000,000 explicit & finalized).

Change

Adds --gas <gasLimit> to both deploy and write, threaded through to genlayer-js's writeContract/deployContractgas option (see genlayer-js#205, which adds that option and this PR depends on).

Added a parseGasLimit helper next to the existing parseValidUntil in fees.ts, reusing the same parseBigNumberishOption validation (non-negative integer, decimal or 0x-hex) plus a positive-value check specific to gas.

Dependency note: this PR's own tests mock the genlayer-js client, so they pass regardless of merge order. But the --gas flag has no actual runtime effect until genlayer-js#205 ships, since older genlayer-js versions don't read a gas field at all (it's silently ignored — the writeParams/deployParams objects here are any-typed, so nothing breaks, it just won't do anything yet).

Testing

9 new cases across tests/actions/{write,deploy}.test.ts: valid override passed through as a bigint, omitted when not provided, invalid value rejected before the SDK call (via the existing failSpinner error path, not a thrown rejection — matches how every other validation error in this codebase surfaces), zero rejected.
2 new cases in tests/commands/{write,deploy}.test.ts: confirms the --gas CLI flag is actually parsed by commander and reaches the action.
Full suite: 585 passed, 52 files, no regressions.
npx tsc --noEmit: 0 new errors in any file I touched (write.ts, deploy.ts, fees.ts, commands/index.ts). The existing pre-existing errors elsewhere (staking/vesting/keychain) are from this repo's source being ahead of its currently-published genlayer-js npm dependency — unrelated to this change.

Summary by CodeRabbit

New Features
- Added an optional --gas option to contract deployment and write commands.
- Users can specify an explicit gas limit, bypassing automatic gas estimation.
- Gas values are validated and must be positive integers or valid hexadecimal values.
Bug Fixes
- Invalid gas values are rejected with clear error messages before transactions are submitted.

On Bradbury, `genlayer write` used the exact eth_estimateGas result as the outer EVM gas limit, and the transaction reverted twice before GenVM was ever reached; identical calldata succeeded when replayed with a larger explicit gas limit. The CLI exposed no way to override gas estimation for either deploy or write. Adds `--gas <gasLimit>` to both commands, threaded through to genlayer-js's writeContract/deployContract `gas` option (see genlayer-js PR genlayerlabs#205, which this depends on — this PR's tests use a mocked genlayer-js client so they don't need that change merged first, but the flag has no runtime effect against genlayer-js versions that don't understand the `gas` field yet). Added a `parseGasLimit` helper next to the existing `parseValidUntil` in fees.ts, reusing the same `parseBigNumberishOption` validation (non-negative integer, decimal or 0x-hex) plus a positive-value check specific to gas (zero isn't a meaningful gas limit). Tests: 9 new cases across tests/actions/{write,deploy}.test.ts (valid override passed through as bigint, omitted when not provided, invalid value rejected before the SDK call, zero rejected) and tests/commands/{write,deploy}.test.ts (CLI flag parsing reaches the action). Full suite: 585 passed (52 files), no regressions. TypeScript: 0 new errors in any file I touched (`npx tsc --noEmit` shows pre-existing, unrelated errors in staking/vesting/keychain code from genlayer-cli's source being ahead of its published genlayer-js dependency — none in write.ts, deploy.ts, fees.ts, or commands/index.ts).

📝 Walkthrough

Walkthrough

The deploy and write commands now accept an explicit outer EVM gas limit. The shared parser validates and converts the value to bigint, and the actions pass it to deployContract or writeContract without gas estimation.

Changes

Explicit gas limit support

Layer / File(s)	Summary
Gas option contract and validation `src/commands/contracts/fees.ts`, `src/commands/contracts/deploy.ts`, `src/commands/contracts/write.ts`, `src/commands/contracts/index.ts`	Adds the `--gas` option to deploy and write. Validates positive numeric or hexadecimal values and converts them to `bigint`.
Action gas forwarding `src/commands/contracts/deploy.ts`, `src/commands/contracts/write.ts`	Passes the parsed gas limit to `deployContract` and `writeContract` when provided.
Gas option coverage `tests/actions/deploy.test.ts`, `tests/actions/write.test.ts`, `tests/commands/deploy.test.ts`, `tests/commands/write.test.ts`	Tests forwarding, omission, conversion, and rejection of invalid gas values.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk:⚪ Minimal · up to 2da69

Deploy and write now accept validated explicit gas limits and forward them as bigint values, while preserving automatic estimation when omitted. No merge-blocking product risk remains.

Skipping this one: the @/* alias is configured in tsconfig.json but isn't actually used anywhere in this directory — deploy.ts, estimateFees.ts, and all 6 imports in index.ts consistently use relative ./fees-style imports. Switching just this one line to @/commands/contracts/fees would make it the only alias-style import among its siblings, which trades one inconsistency for another. Kept it relative to match the actual, 100%-consistent local convention.
