# Current status: this template matches the repository's current op-geth-based
# stack. Optimism says op-geth support ends on May 31, 2026 and Glamsterdam
# will require op-reth. op-node is not being deprecated, but this template does
# not yet include an op-reth execution path.
# For long-lived nodes, treat this as the current stack only and plan an
# op-reth migration window now.

# Recommended first run for the current op-geth-based stack: ink-sepolia + full
NETWORK_NAME=ink-sepolia

# "full" starts from an empty datadir. This is the recommended first run.
# "archive" restores from a per-network geth snapshot pointer during
# bedrock-init and needs much more disk. If the snapshot lookup fails, switch
# back to full.
NODE_TYPE=full

# For a quick Sepolia smoke test, these public endpoints worked during docs
# validation:
# - https://ethereum-sepolia-rpc.publicnode.com
# - https://ethereum-sepolia-beacon-api.publicnode.com
# For a long-running node, use a provider with higher rate limits.

# quicknode, and erigon.
OP_NODE__RPC_TYPE=basic

# L2 RPC used by the healthcheck sidecar for comparison.
# The per-network env files provide defaults, and this value overrides them.
