Overall risk: low
Summary:
This is a well-designed and cleanly executed PR. The introduction of rpcRegistry.ts, the move towards a FallbackProvider, and the cleanup of local address.json requirements vastly improves multi-chain support and reliability. The command lifecycle mutations and per-chain context caching (orderCtxCache) are highly efficient. I have identified a few edge cases: an indefinite hang risk on unresponsive RPCs (missing timeout) and a silent error swallow on malformed DDOs that leads to a deep crash.
Comments:
• [WARNING][performance] Creating a JsonRpcProvider directly from a URL string uses default network timeouts, which can cause the CLI to hang indefinitely (or for several minutes) if the user provides an unresponsive or blackholed RPC endpoint. This occurs on CLI startup or during addChain. Wrapping the URL in a FetchRequest with an explicit timeout resolves this.

- Line 233: Update the chain-routing documentation to distinguish startCompute

without an explicit chain.

- Around line 260-264: Update the RPC registry persistence flow so
environment-derived chain IDs, including the resolved legacy URL ID, are tracked
and excluded from the object serialized by persistConfig. Ensure loadRegistry
records these IDs when merging RPC-derived chains, and clear the tracking state
alongside chainUrls during teardown so stale IDs cannot affect later registry
lifecycles.
- Around line 1-9: Update the scope header comments in rpcRegistry.ts to
accurately describe the implemented multi-chain support, including runtime
addChain, removeChain, and setDefaultChainId operations, rpc.json persistence,
and node-free CLI exposure through cli.ts. Remove the outdated “one active

Exclude RPC-derived chains from persistence.
loadRegistry adds RPC chains to chainUrls, and persistConfig serializes every entry. A later setDefaultChainId, addChain, or removal of another chain can therefore write an env-derived chain to rpc.json. If that chain is later removed from RPC, loadRegistry reads it back because the merge only gives the environment precedence on conflicts. Track env-derived IDs, including the legacy URL after resolution, and skip them in persistConfig. Clear the tracking state with chainUrls during teardown.

Align the displayed default chain with the chain that commands actually use.
listChains marks the default with resolveDefaultChain(nodeChains), which also resolves a unique node∩registry intersection. resolveChainId (line 309) reads only getDefaultChainId(). With two or more configured chains and no persisted default, listChains prints [default] for a chain, and a chain-explicit command still fails with "No chain specified and no default chain is set". Use the same resolution in both places.

The payment amount is converted with the active-chain signer, not the payment-chain signer.
paymentChainId can differ from the chain of signer. Line 1086 calls unitsToAmount(signer, initResp.payment.token, ...), which reads the token decimals through the active chain's provider. On a cross-chain payment the token address does not exist on the active chain, so the conversion returns a wrong amount or throws after initialization already succeeded. Obtain the payment-chain signer (for example through the registry) and use it for this conversion.

addChain can strand an unresolved legacy RPC URL.
With a legacy single-URL RPC, loadRegistry stores the URL in pendingLegacyUrl and leaves chainUrls empty. A following addChain(137, ...) then makes chainUrls.size === 1, so line 475 sets defaultChainId = 137 while pendingLegacyUrl stays set. ensureDefaultChain and getActiveChainId both return early on a defined defaultChainId, so the legacy URL is never probed or registered. Its chain becomes unreachable: hasChain returns false, getProvider throws No RPC configured for chain …, and setDefaultChainId(<legacyChainId>) reports the chain as not configured.
Resolve the legacy URL before registering the new chain, so both chains exist and the pre-existing default is preserved.

In `@test/rpcRegistry.test.ts` around lines 191 - 196, Update the registry test
setup across both sites: in the describe containing the afterEach around lines
191-196, set RPC_CONFIG_FILE to a temporary test file in beforeEach and restore
its original value in afterEach; in the describe at test/rpcRegistry.test.ts
lines 253-253, capture the original CHAIN_ID and restore it after each test
instead of allowing deletion to leak. Keep existing RPC restoration and registry
reset behavior unchanged.

Closes #171
Multiple-RPC & multi-chain support (fallback provider, runtime chain management, multi-chain compute)
Turns the CLI from one chain / one RPC endpoint into a runtime RPC registry: multi-URL
failover per chain, a JSON-map
RPCenv, runtime commands to add/remove/switch chains (persisted),and true per-asset multi-chain compute. Backwards compatible — every existing single-URL invocation,
test, and CI job behaves byte-for-byte as before.
Shipped as the three phases of the multi-RPC plan, each independently green.
Phase 1 — RPC foundation: fallback provider + config cleanup
src/rpcRegistry.ts— the single in-process source of truth for RPC endpoints, providers,signers and per-chain contract config (mirrors
nodeConnection.ts): seeded from env, memoized,torn down on exit.
RPCaccepts either form: the legacy single URL (unchanged) or a JSON map keyed by chainIdwhose values are a URL or an ordered list of URLs, e.g.
{"1":"https://eth","8453":["https://a","https://b"]}.A chain with ≥2 URLs is served by an ethers v6
FallbackProviderbuilt the right way:quorum:1(default would require agreement, the opposite of failover),priority = declaration order, a per-backendstallTimeout, and astaticNetworkon every inner provider. The declaredchain is verified once, lazily, on first use (
eth_chainId): confirmed mismatches are droppedwith a warning, an endpoint merely unreachable-now is kept for runtime failover, and it hard-errors
only if every endpoint is on the wrong chain. Malformed
RPCfails fast increateCLI()with anexample; the unset message stays the test-asserted
"Have you forgot to set env RPC?".getConfigByChainId. Contract addresses now come from ocean.jsConfigHelperviagetConfigFor(chainId)(memoized,ADDRESS_FILEelse the bundled multi-chainset), using the lib's lowercase field names (
escrow/oceanTokenAddress/accessListFactory).This is why escrow/mint/access-list now work off-Barge.
mintOceanresolves its token as--token→config.oceanTokenAddress→ clear bail (some chains, e.g. Base, ship no Ocean token).destroyProviders()wired into theindex.tsexit path next tostopP2P()/flushOutput()(providers hold timers that keep the event loop alive).
Phase 2 — Multi-chain plumbing + runtime chain commands
Five node-free runtime commands (grouped under "Chains & RPC" in help; in
NODE_FREE_COMMANDS):addChain <chainId> <rpcUrl...>addRpcremoveChain <chainId>removeRpclistChainsgetRpcs,chainssetChain <chainId>useChaingetChaincurrentChainPersistence to
~/.ocean/cli/rpc.json(overrideRPC_CONFIG_FILE) — same JSON-map shape asRPCplus adefaultChainId, so runtime-added chains survive a restart. Load order: envRPCfirst, then merge the file, env wins (CI/env runs stay deterministic). All persistence I/O is
defensive — a missing/locked file never breaks a command whose blockchain work already succeeded.
Default-chain resolution:
setChain/CHAIN_ID→ the sole configured chain → the single chainboth the node serves and the registry knows → none.
Per-command chain routing (one flag everywhere:
--chainId):publish/publishAlgo/editAsset/allowAlgo/downloadroute tothe DDO's own
chainId(also fixes the old bug wherepublishignored the DDO's chainId).mintOcean, all escrow, all access-list, and the escrow-paidstartService/extendServicetake--chainId(flag → default → error). Services aresingle-chain:
--chainIdis the sole chain and must be one the env prices on.getNodenow flags any chain the node serves for which no RPC is configured.Phase 3 — Multi-chain compute (per-asset ordering + two-chain payment)
--chainIdonstartCompute/startFreeCompute= the payment/escrow chain, independent ofwhere the assets live.
per-chain, per-call memoized
orderCtxFor(chainId)→{signer, config, Datatoken}, replacing thesingle
Datatokenon the signer's one chain. Escrow,verifyFundsForEscrowPayment,deposit/authorize and
ProviderInstance.initializeCompute/computeStartall run on the paymentchain (
signerFor(paymentChainId)). A job may mix asset chains and pay on another. In thecommon single-chain case this is equivalent to before.
ensureComputeChainsRegistered): every chain the job touches (payment +each asset chain) must have a registered RPC and an ocean.js config, errored before any paid
order so a config-less chain can't crash the job after the algorithm is already paid. The
computeEnv.feescheck is now keyed on the payment chain (must be in bothenv.feesand theregistry).
getComputeEnvironmentsnow prints, per env, the fee chains and their accepted tokens (free vspaid), so
--chainId/--paymentTokenare choosable without reading raw JSON.Review fixes (from an adversarial code-review pass)
A high-effort review flagged unguarded null
Config(ocean.jsConfigHelperreturnsnullfor achain it doesn't bundle). Fixed:
configForand theCommandsconstructor now throw a clear,actionable error instead of an opaque
TypeError; the compute pre-flight requires a config forevery chain up front (no partial-payment crash);
parseRpcEnvnow shape-validates the legacysingle-URL too (fail-fast as documented);
removeChainwarns when removing an env-provided chain.v5 DDO routing fix (from CI). Category-(b) routing read the DDO's chainId from the top level,
which is correct for 4.1.0 DDOs but
undefinedfor v5 DDOs (they carry it undercredentialSubject.chainId), so publishing a v5 metadata file bailed with "no valid chainId". Ashared version-aware
getDdoChainId()helper reads whichever location is present, used at everyrouteToAssetChainsite (publish/publishAlgo/editAsset/allowAlgo/disallowAlgo/download)and in the compute path (
computeJobChainIds+ per-assetorderCtxFor), so both DDO versionsroute and order correctly.
Second review round.
FetchRequestwith an explicit 5 stimeout, so an unresponsive/blackholed RPC fails fast instead of hanging the CLI on startup or
addChain.ensureDefaultChainnow routes its legacy-URL probe through the samemockable, timeout-protected
chainProbe(previously a bespokeJsonRpcProvider.getNetwork()thatbypassed both the test mock and the timeout).
computeJobChainIdsnow throws with a labelled message on a non-nullDDO with no resolvable chainId instead of silently dropping it — which previously bypassed the
up-front chain validation and crashed later as
orderCtxFor(NaN).ensureComputeChainsRegisteredcatches it and bails cleanly.
