Streaming Payment

Overview

A streaming payment releases or accrues value continuously or in very small time-based increments instead of paying one fixed amount at a single moment. It can support salaries, subscriptions, services, grants, and usage-based compensation.

The implementation may update a ledger continuously, calculate accrued value when queried, use a smart contract , or periodically transfer accumulated amounts. The displayed continuously changing amount may be calculated rather than settled on every increment. Reconciliation should reproduce the accrued amount from the rate and active intervals and connect withdrawals with authoritative transfers. The operating record should preserve the original obligation, participants, amount, currency or asset, authoritative identifiers, timestamps, state history, exceptions, and final financial effect. Important failure modes include duplicate or delayed events, wrong destinations or currencies, stale instructions, unavailable providers, unsupported retries, and customer-facing status that differs from authoritative records.

Streaming Payment should remain distinct from smart contract and Payment Fee, because each can represent a different stage, record, control, or financial outcome.

Smart-contract risk, network fees, clock assumptions, access control, and funding depletion can interrupt the stream. Teams should design for lost or duplicated work, unbounded retries, stale state, dependency failure, weak observability, and unsafe recovery.

The agreement should define start and end times, rate, asset, precision, funding, withdrawal rights, pause and cancellation rules, and treatment of rounding or insufficient balance. Operations must distinguish accrued, claimable, withdrawn, settled, and refunded value. Controls should validate inputs server-side, authenticate external events, make irreversible actions idempotent, and reconcile provider, network, settlement, and ledger evidence. For Streaming Payment, the authoritative record and completion rule should be documented before any irreversible operational, customer, or accounting action is released.
