Fystack vs Fordefi: DeFi Trading Infrastructure vs Payment Settlement

BD & Growth @Fystack
Fystack and Fordefi are fundamentally different products solving different problems. Fordefi is built for DeFi protocols and trading institutions, while Fystack is built for fintechs, payment companies, and on/off ramps.
Fordefi's platform prioritizes protocol risk, smart contract interactions, and on-chain trading complexity. Fystack's platform prioritizes operational risk, AML screening, fund consolidation, and settlement. Below we detail how these priorities shape pricing, deployment, and infrastructure.
Pricing and Access
Fordefi's sales-driven model gates access. No test without talking to sales. No pricing transparency without contract negotiation. This works for institutional trading funds making multi-million-dollar custody decisions.
Fystack's self-serve model removes gatekeeping. Free tier is available with our SaaS plan. Transparent pricing. When ready to discuss commercial terms, one closing call.
Table 1: Pricing & Features
Fordefi's model is built for institutional deals: you need multiple conversations before you can even test. Fystack lets you start building immediately and talk to us when you are ready to scale.
Table 2: How You Get Access
Who Each Platform Serves
Their positioning: "Decentralized finance is revolutionizing our global financial ecosystem. Institutions now find themselves at greater risk, exposed to potential fraud and hacks when leveraging legacy custody solutions that are not equipped to address the complexities of DeFi."
This is exactly right for their audience: traders facing smart contract risk, protocol interactions, institutional volume, and on-chain complexity. Fordefi's strength is DeFi-native security.
Fystack serves fintechs, payment companies, crypto exchanges, and neobanks. The workflow is different: fund consolidation (auto sweep), regulatory screening (AML/KYT), settlement operations, treasury management. Operations and payments.
The free tier targets developers. Pro plan targets early-stage teams validating product-market fit and Growth plan serves scaling teams needing multi-chain support.
Open-Source and Developer Access
Fordefi: Closed Proprietary Platform
Fordefi maintains proprietary control over its codebase. The platform is delivered as SaaS only. There is no option to self-host, fork, or audit the underlying MPC implementation. For teams that need custody to run inside their own infrastructure, Fordefi is not an option.
Fystack: Open-Source, Self-Hosted
mpcium is a deployable MPC node daemon written in Go. It ships with docker-compose, systemd unit files, NATS for inter-node messaging, Consul for service discovery, and client SDKs in TypeScript and Go. A competent engineer can go from cloning the repository to a running three-node MPC cluster in roughly one day.

Deployment and Key Management
Fordefi: AWS Nitro Enclaves, Vendor Lock-In
Fordefi runs server-side key shares in AWS Nitro Secure Enclaves. This means Fordefi controls the infrastructure where your key material is processed. You cannot move to another cloud provider or run the system in your own data center. You are locked into Fordefi's infrastructure decisions.
Fordefi also offers a Wallet-as-a-Service (WaaS) model where platforms embed Fordefi's wallets directly into their applications. This is valuable for platforms that want wallet infrastructure without building it themselves.
Fystack: Self-Hosted, Customer-Controlled Infrastructure
Fystack runs as SaaS or as fully self-hosted deployment via Docker or Kubernetes. Key material is stored in the customer's own AWS KMS, GCP KMS. There is no AWS Nitro lock-in. You own your deployment.
The hybrid mode, where the customer holds one shard, Fystack holds one, and a trusted third party holds one, is in active development and expected in Q4 2026.

Honest Trade-Offs
Fordefi's genuine advantages: $120B+ monthly volume safeguarded, DeFi expertise (protocol interactions, smart contract risk analysis, in-app swaps), production mobile app, institutional exchange connectivity, and Paxos backing (regulated custody integration). If your business is institutional DeFi trading, Fordefi is purpose-built for you.
Fystack's trade-off: open-source (mpcium deployable), self-hosted by default, transparent pricing, operations-focused (auto sweep, AML, settlement). Mobile app still in development. We optimize for fintech and payment infrastructure. If you need to own your custody and operate transparently, Fystack fits.
Which Platform Should You Choose?
Choose Fordefi if your team is an institutional trading fund or DeFi protocol, you need a mobile app for traders, you process high volumes of dApp interactions, or you are building a platform that wants white-label wallet infrastructure via WaaS. Fordefi's $120 billion in monthly transaction volume and Paxos backing (as of November 2025) demonstrate genuine production depth for institutional trading workflows.
Choose Fystack if you are a fintech, payment company, or exchange building custody infrastructure from scratch, you need transparent pricing from day one, you want to self-host and own your infrastructure, or you want the freedom of open-source optionality. The free tier is available at Fystack with no credit card required. mpcium is public at Fystack's GitHub.
