Consensus RPC

Advanced
Verifier beacon RPCs (optional)

When set, Helios bootstrap requires the finalized root to come back byte-equal from the primary RPC and every verifier. Defeats single-operator compromise of the bootstrap anchor. Leave empty for today's single-source behavior.

Pinned checkpoint root (optional)

Lock Helios bootstrap to a specific finalized block root that you've independently verified. Skips the live fetch from the consensus RPC entirely. Leave empty to fetch a fresh root on every boot.

## Web3:// dapps (ERC-4804)

Onchain HTML pinned to your local Kubo node. Each entry was fetched via Helios-verified `eth_call` and is served from `<cid>.ipfs.localhost:8080`. Evict an entry to drop the pin and free Kubo storage.

## Gateway interception

Rewrites public ENS gateways to the underlying name/address and resolves locally. Turn off to fall back to the public gateways.

Intercept eth.limo / eth.link links Rewrites `*.eth.limo` / `*.eth.link` to the underlying `.eth` name. Requires a local IPFS node. Intercept w3eth.io links Rewrites `0x<addr>.w3eth.io` to a local ERC-4804 resolution. Requires a local IPFS node.
