# Chain 138 path for deployer gas auto-route: try token-aggregation quote for cUSDT/cUSDC → WETH.
# If no c*→WETH pool exists (current state), output "use genesis/validator only".
# Uses config/deployer-gas-routes.json for 138 entry (tokenAggregationBaseUrl, token addresses).
#
# Usage:
#   ./scripts/deployment/chain138-tokens-to-gas.sh [--dry-run] [--amount-raw WEI]
#   TOKEN_AGGREGATION_URL=https://dbis-api.d-bis.org/api/v1 ./scripts/deployment/chain138-tokens-to-gas.sh
#
# Requires: curl, jq. Optional: RPC_URL_138, PRIVATE_KEY for execute path (not implemented in v1).
