Resolved blockchain fields.

Fields

rpc_url: String

JSON-RPC endpoint URL.

eth_keystore: PathBuf

Ethereum keystore file path.

keystore_password_file: Option<PathBuf>

Optional path to a file holding the keystore password. CLI/env-only; not surfaced via the TOML schema (passwords don’t belong in config files even by reference). The runtime first consults the DECDN_KEYSTORE_PASSWORD env var, then this file, then prompts on stdin if connected to a TTY. Each source is chosen by presence, so a set-but-empty env var and an empty file both mean an empty password.

payment_pool_address: String

PaymentPool contract address — the shared payment pool this node registers against for buyer and seller flows alike.

capacity_bond_address: String

CapacityBond contract address.

origin_assignment_address: Option<String>

OriginAssignment contract address. Some only when the operator opts into the chain-backed origin directory; None => empty directory, so the FIND_VALUE routing fallback (ADR 022) resolves nothing.

origin_directory_positive_ttl_sec: u64

Positive-hit TTL for the lazy origin directory cache, in seconds: how long a resolved, non-empty getOrigins(namespaceId) set is served before a re-read. Defaults to super::DEFAULT_ORIGIN_DIRECTORY_POSITIVE_TTL_SEC.

origin_directory_negative_ttl_sec: u64

Negative-hit TTL for the lazy origin directory cache, in seconds: how long “this namespace has no origins / does not exist” is cached. Defaults to super::DEFAULT_ORIGIN_DIRECTORY_NEGATIVE_TTL_SEC.

origin_directory_cache_capacity: usize

Max distinct namespaces held in the lazy origin directory cache (LRU eviction). Defaults to super::DEFAULT_ORIGIN_DIRECTORY_CACHE_CAPACITY.

publisher_registry_address: Option<String>

PublisherRegistry contract address. Independent of the origin directory (the publish CLI’s namespace create target); not consumed by the node.

slash_judge_address: String

SlashJudge contract address — the EIP-712 verifyingContract for slash_sig signatures (ADR 014). Required (no default).

content_blacklist_address: Option<String>

Required ContentBlacklist contract address (ADR 011/019/031). Successful node config resolution always produces Some; the runtime rejects None.

content_blacklist_poll_interval_sec: u64

Seconds between the blacklist watcher’s periodic replay + re-scope pass. Defaults to super::DEFAULT_CONTENT_BLACKLIST_POLL_INTERVAL_SEC. Only used when content_blacklist_address is set.

chain_staleness_grace_sec: u64

Seconds the node may go without a successful chain read before the serve and probe paths refuse (ADR 011 § Serving while chain-stale). Defaults to super::DEFAULT_CHAIN_STALENESS_GRACE_SEC. Always evaluated; a large value opts out. Only used when content_blacklist_address is set.

chain_id: u64

EIP-712 chainId for the slash_sig domain separator. Defaults to super::DEFAULT_CHAIN_ID (Arbitrum Sepolia) when unset.

rpc_watchdog_interval_sec: u64

Seconds between RPC connectivity watchdog probes. 0 disables the watchdog entirely; otherwise the resolver enforces a minimum (see MIN_RPC_WATCHDOG_INTERVAL_SEC).

event_poll_interval_ms: u64

Milliseconds between chain-event poll ticks (#1011, #1106). Two unrelated consumers read this one value:

• the MultiplexedPoller’s poll_interval — the eth_getLogs tick cadence shared by every chain watcher’s Route.
• alloy’s pending-transaction receipt heartbeat, applied to every provider via the node’s with_poll_interval (client().set_poll_interval) and consumed by PendingTransactionBuilder::get_receipt when the node awaits a mined settlement / pool tx. This is also what overrides alloy’s localhost-detected 250 ms default.

Defaults to 7000 ms (DEFAULT_EVENT_POLL_INTERVAL_MS); the resolver enforces a minimum (see MIN_EVENT_POLL_INTERVAL_MS).

get_logs_max_block_span: u64

Ceiling on the block span of one chain-watcher eth_getLogs request (the MultiplexedPoller’s window). The poller starts here. When the provider rejects a range, it sets its span to half the rejected window’s length, and it doubles back toward this ceiling after a streak of accepted windows. Defaults to super::DEFAULT_GET_LOGS_MAX_BLOCK_SPAN; always >= 1.

fee_shares_poll_interval_sec: u64

Seconds between authoritative FeeRouter.getShares() re-reads by the fee-shares watcher (ADR 041 / ADR 016 § Tunable Economics). Safety-net cadence alongside the SharesUpdated event subscription. Defaults to 3600s (DEFAULT_FEE_SHARES_POLL_INTERVAL_SEC); the resolver rejects 0.

redeem_threshold_micro_usdc: u64

Per-chunk redemption floor (base units, µUSDC). The seller settlement path submits an on-chain redemption transaction for a chunk of lanes only once the aggregate un-redeemed value across that chunk’s lanes reaches this floor; every lane in a submitted chunk settles. Defaults to 1 USDC (1_000_000 µUSDC) when unset.

redeem_max_vouchers_per_tx: u64

Maximum vouchers per redeemMany transaction (the redemption chunk size). Defaults to 300 (DEFAULT_REDEEM_MAX_VOUCHERS_PER_TX); the resolver rejects 0.

redeem_interval_secs: u64

Seconds between the redeemer self-tick sweeps (#327, #751): the low-frequency backstop that sweeps every lane and redeems the chunks that clear the redemption floor, independent of the advisory per-voucher hints. Defaults to 300s (DEFAULT_REDEEM_INTERVAL_SECS); the resolver rejects 0.

buyer_working_deposit_micro_usdc: u64

Deposit (base units, µUSDC) the buyer path escrows when it opens a pool, and the target every top-up restores the pool balance toward. Defaults to 10 USDC (10_000_000). Guaranteed nonzero (the resolver rejects 0; the pool’s openPool reverts on a zero deposit).

buyer_max_approve: bool

Whether the buyer path issues a one-time max USDC approval for the PaymentPool contract at startup (#744, ADR 003 § Deposit Economics). Defaults to true; set false to manage the allowance out-of-band (e.g. a tighter per-pool approval policy).

pool_min_remaining_deposit_micro_usdc: u64

The node’s refundable floor M (base units, µUSDC), sized per ADR 003 § Sizing (M = k·ρ·B·Δ). The node stops serving a pool once its remaining on-chain balance minus M can no longer cover the next credit window. Defaults to 1 USDC (1_000_000 µUSDC).

pool_floor_signer_live_windows: u64

Per-signer LIVE concurrency cap k, in ramp-start credit windows (ADR 003 § Pool solvency, per-signer floor isolation): the most live un-vouchered floor reservation any one capability signer may hold against a pool, k · one credit window. Lower-clamped to one window at use. Defaults to 8 — see decdn_common::config::DEFAULT_POOL_FLOOR_SIGNER_LIVE_WINDOWS.
