Two products, one protocol: decentralised on/off-ramp + institutional net settlement—never custodying funds.

Introducing PayNet — 577,884 obligations settled. Privacy mode: COMMITTED. The FiatRails Settlement Computer is built as six interlocking products on a single sovereign Avalanche L1. Today I'm sharing one of them: PayNet. PayNet is the micro-transaction aggregation layer. High-frequency payment flows — remittances, merchant settlements, mobile money — generate thousands of small obligations that would overwhelm traditional netting windows. PayNet aggregates these into settlement-ready positions before they reach the multilateral netting engine. No system globally performs multilateral netting on micro-transaction flows. Deployed netting infrastructure (CLS, Partior, Fnality) is exclusively wholesale. Remittance and mobile money providers settle gross or simple bilateral. PayNet bridges this gap — on encrypted values. Patent pending. Every obligation is committed using Pedersen cryptographic commitments with Bulletproof range proofs. The netting engine never sees plaintext amounts. What you're looking at: - 6 corridors processing West and East Africa flows - 577,884 obligations settled on-chain - 837,982 AI-powered format translations (legacy MT → ISO 20022 CBPR+) - 503 post-quantum verifications (ML-DSA, FIPS 204) - Compression: 85–95.5% per corridor - Running 24/7 in committed mode Learn more: fiatrails.network/paynet PayNet sits alongside Settlement, RiskNet, Trade, Grid, and Nexus — all sharing one chain, one compliance layer, one privacy stack. This isn't a demo. It's a perpetual soak test running for weeks. Settlement infrastructure should prove itself before it asks for trust. #Settlement #CrossBorder #Avalanche #Blockchain #Fintech

95% netting compression. Proven on testnet. Not a projection. We just closed our largest test cycle on Lagrange (our Avalanche L1 testnet): - $12.13B gross obligations processed - 95% compression — meaning 95 cents of every dollar netted out before settlement - 11 live corridors across USD, AED, NGN, GBP, EUR, KES - 434 cross-corridor netting rounds - 23,000+ obligations through PayNet alone For context, CLS — the $7T/day settlement utility used by the world's largest banks — publishes 92% compression. They serve 75 direct members. We're building for the other 38,000. What does 95% compression actually mean for a bank? A corridor processing $100M/day in gross obligations settles just $5M. The other $95M never moves. No nostro funding required. No trapped capital. No correspondent chain. This isn't theoretical. Every number above comes from our live testnet — real netting windows, real multilateral offset calculations, real settlement instructions generated. The settlement layer works. Next step: institutional pilots under regulatory supervision.

Here's the next question every institution asks: "If I put my settlement data into a shared netting engine, who else can see it?" It's the right question. In a multilateral netting system, the engine needs to see all obligations to compute optimal nets. But your volumes, your counterparties, your growth rate, your corridor mix — that's competitive intelligence. No bank or PSP will put that on a chain where competitors or validators can observe it. CLS solves this by being a trusted black box. You trust CLS because it's regulated and systemically important. That's privacy by policy. We solved it with cryptography. The FiatRails privacy layer — deployed and verified on all 11 testnet corridors: - Pedersen commitments (BN254) for obligation amounts — homomorphic, so the netting engine computes on encrypted values without ever seeing them - Bulletproofs for zero-knowledge range proofs — 70ms proving, no trusted setup - AES-256-SIV for metadata encryption — counterparty addresses, transaction IDs, all encrypted at rest - Shamir's Secret Sharing for master key distribution — no single validator can access the data - Tiered view keys: governance sees everything, central banks see their corridor, participants see only their own data - Participant-sovereign delegation: you control who sees your data, with granular scoping, time limits, and instant on-chain revocation This is not "privacy by policy." It's privacy by mathematics. The first netting system globally where institutions can trust the engine without trusting each other. Built on a sovereign Avalanche L1. Post-quantum authentication (ML-DSA, FIPS 204) already deployed — because settlement records have 20-year retention requirements. Monday: the compression numbers. #CrossBorderPayments #Privacy #ZeroKnowledge #Avalanche #Settlement #Fintech

Here's the problem nobody's solving for 99% of financial institutions. Every day, $4.7 trillion sits trapped in nostro and vostro accounts around the world. That's capital banks park overseas just so they can settle cross-border payments. Not earning. Not deployed. Just sitting there, waiting. CLS — the closest thing to a solution — serves 75 member banks. Seventy-five. There are 38,000+ banks globally, thousands of PSPs, hundreds of fintechs processing cross-border flows. They all settle bilaterally. Slowly. Expensively. With trapped capital on both sides. It gets worse. 83% of African currencies have zero payment-versus-payment settlement coverage. No netting. No compression. Every transaction settles gross. A $10M corridor between two PSPs requires $10M in pre-funded capital — on each side. Multilateral netting changes this. Instead of every party settling every obligation individually, a netting engine calculates the minimum set of payments needed to settle everyone's positions simultaneously. $100M gross becomes $9M net. Capital freed. Risk reduced. Settlement in minutes, not days. This is what CLS does for 75 banks. This is what FiatRails does for everyone else. The Settlement Computer is not a better rail. It's the first netting infrastructure built for the institutions that have been excluded from the existing one. Yesterday I shared what we've built. Tomorrow I'll share how we protect it — cryptographic privacy that lets institutions trust a shared netting engine without exposing their data to competitors. #CrossBorderPayments #Settlement #Fintech #Africa #Blockchain #Avalanche

For the past 10 months, I've been building something that doesn't exist in global finance. FiatRails is a Settlement Computer — a sovereign Avalanche L1 blockchain purpose-built for multilateral netting in cross-border settlement. Not a payments app. Not a stablecoin wrapper. Not a routing layer. The L1 is the application. Settlement logic executes as native precompiles at the consensus layer — not as smart contracts deployed on a general-purpose chain. 1,601 TPS on commodity hardware. Why it matters: $4.7 trillion sits trapped in nostro/vostro accounts every day. CLS — the world's largest settlement system — serves 75 members. The other 38,000+ banks, PSPs, and fintechs settle bilaterally, slowly, expensively. 83% of African currencies have zero payment-versus-payment coverage. What we've built and verified on testnet: - 11 settlement corridors across Africa, Middle East, and Asia - 91.2% netting compression on $12.13B simulated gross volume — $11.10B eliminated (CLS publishes 92%) - 11 consensus-layer precompiles in native Go (10,800+ lines) - Cryptographic privacy: Pedersen commitments, Bulletproofs, zero-knowledge range proofs — the first netting system globally to operate on committed values - Post-quantum authentication deployed (ML-DSA, FIPS 204) - PayNet: micro-transaction aggregation with AI-powered ISO 20022 translation, 23,000+ obligations processed - 5 U.S. patent applications filed (~287 claims) Six products. One chain. Built for the institutions that have been locked out of infrastructure that should have existed a decade ago. We've been heads-down building. Time to share what exists. More this week. #CrossBorderPayments #Avalanche #Settlement #Blockchain #Fintech #Africa
