IndexedEx integration (2026-10-19)

Read the repository CLAUDE.md and the relevant Crane/IndexedEx skill before using this topic. Current product law, registry/CREATE3 deployment, production-first tests, build-before-test ordering and configured Foundry profiles override generic examples. This archive-derived guide does not authorize broadcasts, dependency installs, new product integrations or restoration of retired protocol families. Use current deployment artifacts and the pinned frontend/tool versions; archived addresses and API samples are not live verification. Resolve topic names through scripts/codex-skill-catalog.json when they are grouped behind routers.

WETH ops (cast)

Goal

Convert native ETH <-> WETH9.

Prerequisites

WETH address from the current task-selected deployment/registry; see token reference for historical context only.

Safety

Confirm chain and WETH address. Confirm value before deposit.

Inspect

cast call $WETH "balanceOf(address)(uint256)" $USER --rpc-url $ETH_RPC_URL
cast balance $USER --rpc-url $ETH_RPC_URL -e

Execute

cast send $WETH "deposit()" --value 0.01ether \
  --rpc-url $ETH_RPC_URL --private-key $PRIVATE_KEY

AMOUNT=$(cast to-wei 0.01 ether)
cast send $WETH "withdraw(uint256)" $AMOUNT \
  --rpc-url $ETH_RPC_URL --private-key $PRIVATE_KEY

Verify

cast call $WETH "balanceOf(address)(uint256)" $USER --rpc-url $ETH_RPC_URL
cast balance $USER --rpc-url $ETH_RPC_URL -e

Common failures

• Wrong WETH address on L2
• Insufficient ETH for gas + value
