The Challenge
Huma Finance is building the "PayFi" network, a new DeFi category that bridges real-world liquidity for cross-border payments, trade finance, and remittances. To realize this vision, Huma needed to scale from a concept to a high-volume, multi-chain infrastructure capable of processing billions of transactions.
They required a partner who could do more than just write code; they needed a strategic ally to co-develop the core IP, bootstrap the ecosystem, and unlock institutional growth.
The Solution
57Blocks engaged with Huma through a holistic, long-term partnership built on four strategic pillars, ensuring success at every layer of the protocol.
The 4 Pillars of Collaboration:
Product Development (Core Protocol & dApp)We served as the primary engineering arm, partnering with Huma's founders to architect the technical foundation.
Smart Contracts: We built the core credit facility contracts and composable receivables logic, optimizing for extreme gas efficiency to support high-frequency "PayFi" transactions.
Security & Scale: We developed comprehensive invariant tests to ensure the security of on-chain assets, enabling the protocol to scale safely to tens of billions in volume.
Developer Ecosystem: To drive adoption, we built the Huma SDK and Subgraph, providing the critical API layer that allows partners to build applications on top of Huma seamlessly.
Value-Added InvestmentOur commitment extended beyond code. 57Blocks Capital participated in Huma's seed round, providing the resources needed for aggressive early growth. We also acted as an active Liquidity Provider (LP), bootstrapping the protocol's initial pools to ensure immediate liquidity depth for early borrowers.
Ecosystem AccelerationWe actively built and supported partner applications to expand Huma's reach. A key example is Jia Finance, a platform for SMB financing in emerging markets. By helping build Jia, we created a virtuous cycle: increased lending activity on Jia directly drove utilization of Huma's credit pools, benefiting the entire network.
Unlocking PartnershipsLeveraging our industry network, we facilitated critical strategic introductions. We connected Huma with key players like Rain (Web3 corporate cards), leading to the launch of a dedicated credit facility that expanded Huma's utility into corporate spend management and significantly boosted transaction volume.
Business Impact
This full-spectrum partnership accelerated Huma from a seed-stage concept to a market-leading PayFi network. The robust infrastructure built by 57Blocks has enabled Huma to scale massively, now processing tens of billions of loans without a single default. By combining elite engineering with capital and strategic networking, 57Blocks helped establish the foundation for the future of on-chain payments.
Bin and Shan were critical to the success of our core technology. They were also exceptional collaborators for building up our internal team’s smart contract capabilities.”
