Settlement is the completion of the obligations created by a transaction.
The essentials
Settlement is the completion of the obligations created by a transaction. On-chain finality, legal finality and recognition in an institution’s ledger are related but distinct. A block explorer showing success does not establish that every contractual obligation has been discharged.
How it works
Track an instruction through approval, signing, broadcast, inclusion, the applicable finality policy and accounting. Reconciliation compares expected and observed amounts, assets, networks, fees and identifiers. Differences may arise from reorganisation, token decimals, fee deductions, delayed crediting or incorrect network selection.
What to watch
Delivery-versus-payment links delivery of an asset with its payment to reduce principal risk. Two independent transfers are not automatically DvP. A cross-chain transfer or off-chain cash leg needs an explicit coordination mechanism and failure procedure. Define cut-offs, unresolved-item ownership and escalation rather than treating a transaction hash as final evidence of completion.
Understand the details
A trade can be agreed before assets move. Settlement completes the relevant delivery and payment obligations under the arrangement. A blockchain transfer provides technical evidence, but the legal effect depends on the asset, participants and governing rules. A token transfer and an off-chain cash payment can complete at different times.
Boundaries and common mistakes
Delivery-versus-payment aims to link the two legs so one is not finally delivered without the other. Atomic code can help within its execution boundary, but cannot automatically control an external bank ledger. Timeouts, failed legs, reversals and reconciliation must therefore be specified for the complete arrangement.

- 04Reconcile both obligations
Read these as connected concepts, not necessarily consecutive steps.
Read the explanation
A trade can be agreed before assets move. Settlement completes the relevant delivery and payment obligations under the arrangement. A blockchain transfer provides technical evidence, but the legal effect depends on the asset, participants and governing rules. A token transfer and an off-chain cash payment can complete at different times.
Put the mechanism into context
A token delivery is confirmed while the corresponding bank transfer is still pending. Draw separate status tracks for trade agreement, token delivery and cash payment. Identify when the seller is exposed to an unpaid delivery.

Atomic code can help within its execution boundary, but cannot automatically control an external bank ledger. Timeouts, failed legs, reversals and reconciliation must therefore be specified for the complete arrangement.
The distinction that changes the analysis
A transfer can reach the required technical status while an institution still waits for reconciliation or a contractual condition. Use separate timestamps and owners for these stages. A single “done” field hides which condition was actually satisfied.
Explain it yourself
Revisit the case above. Name what is established, what remains to be checked and the evidence needed to conclude. A strong answer addresses both sides of the diagram.
Apply the lesson to a case
A token delivery is confirmed while the corresponding bank transfer is still pending. Draw separate status tracks for trade agreement, token delivery and cash payment. Identify when the seller is exposed to an unpaid delivery.
The two ledgers have independent completion mechanisms unless a specific coordination arrangement links them. A blockchain transaction’s atomicity does not extend automatically to the bank transfer. Specify the dependency, failure response and legal completion point for each leg.
Terms in this lesson
- Hash
- A fixed-length fingerprint computed from data by a hash function. It checks consistency, not truth.
- Finality
- The confidence or protocol guarantee that an accepted history will not be reversed, under stated assumptions.
