Key benefits
- One integration layer for Ethereum, Polygon, Base, Arbitrum, Optimism and Solana.
- Idempotent webhooks with retry and replay — no double-crediting, no silent drops.
- Ledger reconciliation jobs that catch drift between chain state and your database daily.
- Multisig and Fireblocks signing flows with four-eye approval and full audit trail.
How we integrate chains
We map your systems first: where money or assets are recorded, who approves movement, and what must never happen twice. Then we build the seam — managed RPC with failover, event listeners with cursor checkpoints, webhook delivery with signatures and retries, and reconciliation reports that finance can read. Bridging and custodial versus non-custodial rails are chosen per flow, not per fashion.
Failover is drilled, not documented-and-hoped: provider outages, reorgs and stuck transactions all get rehearsed.
What is included
- Integration blueprint and RPC strategy
- Event listeners with checkpointed cursors
- Signed webhooks with retry, replay and dead-letter handling
- Reconciliation jobs and finance-readable reports
- Multisig runbooks and monitoring dashboards
Map the money, then build the seam
Systems mapping
Ledger, approvals and never-twice rules captured with finance and ops.
Integration sprints
Listeners, webhooks and reconciliation built against staging chains.
Stack
Alchemy, QuickNode, Fireblocks, IPFS with provider failover.
Drills
Outage, reorg and stuck-transaction rehearsals before handover.
Proof: institutional custody rails
Zero missed webhooks in six months of vault operations.
Signing policy plus reconciliation your examiners accept.
Yes — integrations land inside your stack with signed webhooks and reconciliation jobs, not a parallel system to babysit.
Managed providers with failover, cursor-checkpointed listeners and replayable delivery, all drilled before handover.
Integration scopes start from $12,000 / ₹9,90,000 for a 4–8 week build. Fixed price follows systems mapping.
