説明

Mantle Cashflow Engine (MCE) is an infrastructure protocol built on Mantle that enables developers to create, manage, and automatically settle tokenized real-world cashflows such as rental income, invoices, service agreements, and subscription-based revenues.

Real-world cashflows follow deterministic rules: funds are locked, time or conditions elapse, and payouts are finalized. MCE abstracts this logic into reusable onchain primitives that handle non-custodial fund custody, settlement timing, and compliant revenue distribution. Mantle serves as the execution and settlement layer where these cashflows are finalized transparently and efficiently.

At its core, MCE provides smart contracts for defining cashflow agreements with parameters such as start and end time, payout amounts, and recipient splits. Funds are held in onchain vaults and released only when settlement conditions are met, ensuring a clear and auditable custody model. Settlement can be triggered automatically based on time or external signals, finalizing the cashflow and distributing funds according to predefined rules.

To support RealFi compliance requirements, MCE models KYC and eligibility checks through onchain abstractions such as allowlists or attestations. This enables compliant distribution flows without embedding full identity systems, keeping the protocol lightweight and infra-focused.

MCE is designed to be composable with DeFi systems. Idle funds locked in vaults can optionally be routed through yield adapters, allowing principal and yield to be accounted for transparently during settlement. Cashflow positions can also be represented as tokens, making them reusable primitives for lending, collateralization, or secondary markets.

Rather than focusing on consumer-facing UX, MCE exposes its functionality through a developer SDK and API. This allows builders to integrate automated cashflow settlement into their own applications while keeping the protocol simple to deploy, test, and extend.

By providing backend infrastructure for tokenized cashflows, Mantle Cashflow Engine demonstrates how Mantle can support scalable RealFi applications with transparent custody, automated settlement, and composable financial logic at the protocol level.

ハッカソンの進行状況

During the hackathon, we designed and implemented the core infrastructure for Mantle Cashflow Engine, focusing on protocol logic rather than UI. We developed and deployed the core smart contracts on Mantle testnet, including cashflow definitions, non-custodial vaults, and an automated settlement engine that finalizes and distributes funds based on predefined rules. The contracts support time-based settlement, recipient split logic, and auditable custody of locked funds. A developer-facing SDK and API were implemented to interact with the protocol, enabling cashflow creation, fund locking, settlement triggering, and inspection of vault balances through scripts and command-line commands. This allowed end-to-end testing and demonstration. We also implemented basic compliance abstractions using allowlists to model KYC-restricted distribution and added support for optional yield routing through a simple adapter interface. Comprehensive tests and logs were used to validate settlement correctness and fund distribution on Mantle.

資金調達の状況

Mantle Cashflow Engine (MCE) is an early-stage hackathon project and has not raised external funding. Development has been self-funded by the core team. The project is currently in the prototype phase, fully developed and tested on Mantle testnet, with plans to explore external funding opportunities after hackathon completion.
