ethereum

const ethereum: object

Ethereum mainnet — priority 4 production chain (institutional use cases).

Casper FFG finalises in epochs (~12.8 min). defaultConfirmations of 32 (~6.4 min at ~12 s blocks) gives finalised-grade safety. Do NOT use Polygon’s 4 here — 4 blocks (~48 s) is nowhere near finalised, and would re-open the settle-reorg gap (threat 2.8). The facilitator auto-sizes receiptTimeoutMs from this depth (~10 min), so the default does not time out. JPYC is live at the same address as the other chains.
