What happens if a blockchain node connected to Nodit becomes unhealthy or falls behind the network?

Nodit's routing logic can evaluate whether a node is following the latest chain state rather than only whether the server process is reachable. If a node is lagging or unhealthy, traffic can be routed away before stale state is used downstream. Block Lag metrics can also be exposed so the institution can incorporate the same signal into its own monitoring and alerting.

What data is available for finance, accounting, and external audit teams?

Wallet Node can support historical state queries, reproducible point-in-time valuation workflows, and retained query or processing evidence used to explain how a balance or valuation was derived. The objective is to provide system-generated evidence that can be reconstructed later rather than relying solely on screenshots or manually maintained spreadsheets.

Wallet Node

The Onchain Infrastructure for Institutional Wallet Operations

Q: Who uses Wallet Node?

Banks and fintech platforms, digital asset exchanges, treasury and asset managers, and custodians and B2B infrastructure providers use Wallet Node to run wallet operations without building node infrastructure themselves.

Wallet Node runs execution, monitoring, and reconciliation for your institution's wallet,

across 70+ chains, under one enterprise SLA.

NEEDS

Building a wallet and operating one at scale require different capabilities

Implementation needs speed and validation. Production needs reliable transactions, accurate balances, and audit-ready operations.

	DURING WALLET IMPLEMENTATION	DURING PRODUCTION OPERATIONS
BUSINESS & IT TEAMS	Define supported chains and traffic profiles · Validate architecture · Run load tests · Review internal control requirements	Operate high-volume deposits and withdrawals · Resolve customer issues · Maintain balance integrity · Support close and audit processes
INFRASTRUCTURE	Chain connectivity · Archive/Trace access · Isolated test environments · Region and private-network requirements	Guaranteed capacity · Automatic exclusion of lagging nodes · Failover · Hard-fork readiness · 24×7 monitoring

WHAT WALLET NODE PROVIDES	Validate capabilities · Dedicated institutional clusters · Reference architecture review	Execute · Observe · Reconcile layers, supported by Assure enterprise operations

THE PROBLEM

Wallet Failures Put Trust and Ledger Integrity at Risk

For institutional wallets, an RPC response isn't enough. What matters is finality, accurate balances, and the ability to explain and recover from failures.

Can we identify transactions likely to fail before execution and avoid unnecessary fees and operational loss?

Pre-execution simulation · Expected asset changes · Gas estimation · Revert reason analysis

If a signed transaction stalls, can we explain what happened to customers and operations teams?

Broadcast status · Pending nonce · Failure classification · Duplicate-submission tracking

If a completed transaction is affected by a reorg, can we correct the customer ledger quickly?

Confirmation depth · Block lag · Reorg detection · Correction events

If an onchain deposit occurred but the customer balance was not updated, can we identify where the gap happened?

Native · Token · Internal Transfer detection · Webhooks · Block-level reconciliation

If the internal ledger and onchain balance diverge, can we locate the missing interval and reconcile it?

Point-in-time balances · Multi-address queries · Historical transaction evidence

Can we reproduce historical transactions and valuations for financial close, tax, or external audit?

Archive access · Transaction-time fiat valuation · Retained audit evidence

IT & Infrastructureoutsource node operations while retaining control: Move hard-fork handling, patching, and overnight incident response into a managed service while independently monitoring metrics such as Block Lag
Service Operationsresolve customer inquiries with evidence: Distinguish where a transaction is delayed and why a deposit was not reflected, using observable transaction and event state
Finance & Accountingkeep internal ledgers aligned with onchain balances: Trace ERP-to-chain balance differences and reproduce point-in-time balances and valuations for close, tax, and audit
Compliancerecord review and audit evidence: Use address and transaction data as first-line inputs to internal review workflows and retain query and processing history for audit support

BUSINESS BENEFITS

Shift Infrastructure Risk to Managed Operations with SLAs

Instead of owning every aspect of chain infrastructure, institutions can define an explicit operating scope with Wallet Node and allow internal teams to focus on customer experience, controls, and business operations.

CRITICAL CAPABILITIES

The Capabilities Institutions Rely on Most in Production

Institutional wallets are not differentiated by API count, but by whether risk is caught before execution and ledgers stay aligned with the chain.

01 · Validate Before Execution

Transaction Simulation

Inspect expected results, revert reasons, gas, and asset changes before submitting — likely failures are filtered and policy checks run before assets move.

Pre-check execution success
Revert reason analysis
Expected gas and fee
Expected asset changes

02 · Real-Time Tracking

Transaction & Deposit Monitoring

Follow a signed transaction from network entry through Pending · Mined · Confirmed to deposit recognition. State stays visible through ledger impact, not just delivery.

Pending nonce and ordering
Stuck
Dropped
Replaced
Internal Transfer deposits
Gap backfill
Dedicated mTLS channels

03 · One operational data layer

Unified Asset & Transaction Data

Portfolio, token transfers, Internal Transactions, and multi-address history in one layer — customer balances, operational tracking, and finance reconciliation read the same onchain data.

Address-level assets
Unified transaction history
Multi-address
multi-chain
Historical state reconstruction
Ledger reconciliation

04 · Financial Value

Native Token Pricing

Retrieve native token prices in USD or KRW to convert onchain balances into fiat value. ETH, SOL, and BTC are evaluated through one workflow across networks.

USD
KRW pricing
Fiat conversion of balances
Customer portfolio value
Treasury reporting
Volume

05 · Counterparty Identification

Address Screening

Enrich addresses and contracts with entity and category data so teams can read a counterparty before funds move. An address surfaces as Exchange or DEX Contract where data is available.

Counterparty identification before transfer
Address-type classification
Entity display in address books
Inputs for allowlist/blocklist policies
Contract inference

06 · State Correction

Reorg Correction

A reorg can change transactions and balances already treated as complete. Wallet Node identifies the affected state and delivers IDs, sequence markers, and dropped-state signals so systems realign with the canonical chain.

Reorg detection
Changed or removed transactions
Correction events
Customer-balance reprocessing

07 · Institutional address scale

Enterprise Address Monitoring

Per-address polling does not scale for exchanges, custodians, and platforms managing hundreds of thousands of addresses. Capacity and topology are designed around address count, event frequency, networks, and peak traffic.

Continuous monitoring of large address sets
Multi-network event processing
High-volume deposit/withdrawal operations
Address-group policies
Dedicated throughput
Dedicated data pipelines

What Institutional Customers Ask Most

Wallet Node is the node and onchain data infrastructure institutions use to execute, observe, and reconcile wallet transactions after signing, across 70+ chains under one enterprise SLA.

You don't need to remove your existing nodes. Nodit can run as an independent second path, since node failures often correlate when they share the same operator, client version, or region. You can keep your nodes as the primary route with Nodit as failover, or split responsibilities, for example internal nodes for submission and Nodit for queries and deposit detection. This also lets you cross-validate node freshness using Nodit's Block Lag metrics. Beyond redundancy, Wallet Node adds the indexing and reconciliation layer, such as reorg correction, deposit detection, and point-in-time valuation, that's costly to build in-house.

The roles are complementary. Your security provider continues to enforce approval policies, protect keys, and produce the signed transaction object. Wallet Node takes over after signing, submitting the transaction to the network, observing its onchain outcome, and returning operational evidence such as execution status, gas consumed, and asset movement. If a system integrator is building the wallet application, Nodit can work with that partner from architecture review through production integration so the key-management, application, node, and data layers are handled as one coordinated project.

Address Screening can help identify the nature of a transaction counterparty before a B2B transfer or withdrawal is approved, and can serve as a first-line input for triage in internal review workflows. More advanced source-of-funds risk scoring, sanctions decisions, and investigation should be handled by a dedicated compliance solution such as Clair or another risk platform, connected to the broader Validate workflow where appropriate.

Production-Ready Architecture for Digital Asset Operations

We assess your target networks, transaction volume, and existing security stack to define the right deployment model. Wallet Node works with your existing KMS, HSM, custody, and SI partners — extending your architecture rather than replacing it.
