Transaction lifecycle services
Build submission, status-tracking, and retry logic for on-chain transactions with idempotency so a retried request can't cause a duplicate action.
Web3 Backend Development
The off-chain half of every on-chain product.
Backend services that connect blockchain state to a usable product — transaction status, reconciliation, notifications, and the APIs a frontend actually calls.
Book a discovery callTHE BUSINESS NEED
Start with the problem.
Build what matters.
Almost no useful blockchain product runs entirely on-chain. Someone still needs to answer 'did my transaction go through,' show a history that makes sense, send a notification, and keep an off-chain database in sync with on-chain events — reliably, even when the chain reorganizes or an RPC node has a bad day.
How we approach it
We treat the blockchain as an eventually-consistent, occasionally-unavailable external system rather than a normal database, and design retries, idempotency, and reconciliation around that reality. Node and RPC provider failover, confirmation depth requirements, and reorg handling are explicit design decisions, agreed with you before implementation rather than discovered in production.
CAPABILITY IN DETAIL
What this means in practice.
Specific engineering work, connected to a business need.
Event listening and reconciliation
Process on-chain events into off-chain state with explicit handling for confirmation depth, chain reorganizations, and missed-event recovery.
API and data layer
Expose clean, versioned APIs backed by Go or Node.js services and PostgreSQL, so frontend and partner integrations don't need to talk to a node directly.
Reliability and monitoring
Configure RPC provider failover, alerting on stalled indexers or failed transactions, and dashboards that show real transaction throughput and failure rates.
WHERE IT CAN HELP
Problems worth solving.
Illustrative engagement types, not claims about previous projects.
- A wallet or dApp frontend that needs a real backend instead of talking directly to a public RPC endpoint
- Keeping an internal database synchronized with on-chain balances or contract state
- Adding reliable notifications for transaction confirmation, failure, or specific on-chain events
BEFORE WE BEGIN
Questions, answered.
Do you build the smart contracts as well?
This service covers the backend around existing or newly built contracts. Contract development itself is covered by our smart contract, Ethereum, and Cosmos SDK development services.
How do you handle a chain reorganization?
Reconciliation jobs are designed to detect when a previously indexed block is no longer canonical and to roll back and reprocess the affected state, rather than assuming every confirmation is final.
Can this integrate with our existing backend?
Yes, Web3 backend services are typically built to plug into an existing Go or Node.js system rather than replace it entirely.
