描述
NetFold is a covered USDG clearing workspace for stablecoin-native businesses on Arbitrum.
Businesses can owe each other money in both directions. Paying every obligation independently makes each gross payment compete for liquidity even when much of the economic exposure offsets.
NetFold lets participants record USDG obligations, requires each named debtor to explicitly accept what they owe, freezes the accepted batch, calculates final net debit and credit positions, and requires complete funding of the residual debit before settlement.
In the canonical example, Studio owes Auditor 100 USDG, Auditor owes Infrastructure 60 USDG, and Infrastructure owes Studio 40 USDG. That is 200 USDG of gross obligations, but after netting only 60 USDG of settlement liquidity is required, producing 70% gross-to-net compression.
The protocol is deployed on Arbitrum Sepolia using canonical Paxos test USDG. Settlement is blocked until a run is fully covered, settlement executes atomically, and a settled run cannot execute twice.
The public application supports the complete browser workflow: create a clearing run, propose obligations, collect debtor acceptance, close the batch, approve and fund the exact residual position, settle, expire, and claim eligible refunds.
Run #001 provides the canonical protocol and accounting proof. Run #002 was created, accepted, funded, and settled through the deployed public frontend using real test wallets, proving the complete product workflow.
NetFold is testnet software, unaudited, and does not provide credit, default mutualization, KYC/KYB, or a legal-netting opinion.

PROGRESS DURING HACKATHON
NetFold was built into a complete working product during the hackathon.
We designed and implemented the NetFoldClearing smart contract with debtor acceptance, batch finalization, net-position calculation, exact residual funding, atomic settlement, expiry, and debtor refunds.
The contract was deployed to Arbitrum Sepolia using canonical Paxos test USDG and independently source-verified. The contract suite now has 40 passing tests, including fuzz and invariant testing.
We built a Next.js production frontend with wallet connection, run creation, obligation proposal and acceptance, role-aware actions, exact USDG approval and funding, settlement, expiry/refund flows, live contract reads, evidence pages, failure simulations, and technical documentation.
Run #001 proved the canonical 200 USDG → 60 USDG → 70% clearing lifecycle.
Run #002 then validated the full production-browser workflow with three wallets. It processed a 10/6/4 USDG obligation cycle, calculated a 6 USDG residual debit, funded exactly 6 USDG, paid 4 USDG to Bob and 2 USDG to Carol, and completed with zero remaining accounted liability.
The public product, documentation, source verification, transaction evidence, demo video, and judge-facing proof pages are all live.
FUNDRAISING STATUS
NetFold has not raised external funding. The project is currently a hackathon-stage testnet prototype focused on validating the product, protocol design, and real user workflow before pursuing further development or fundraising.
