RebelFi

RebelFi is a programmable stablecoin infrastructure provider aimed at the B2B payments layer. Rather than targeting retail crypto users, it builds the infrastructure that payment companies, neobanks, payroll platforms, and enterprises need to deploy idle stablecoin balances into yield-bearing DeFi positions — all without handing custody to a third party. The platform describes its core proposition as turning settlement float — the funds sitting between initiation and final settlement in any payment workflow — into a productive asset.

How It Works

RebelFi exposes its functionality through a TypeScript SDK and a REST API. The architecture is non-custodial by design: RebelFi constructs unsigned transactions and returns them to the caller; the client signs and broadcasts using its own key management infrastructure. The API never touches private keys or holds signing authority at any point.

The integration workflow follows four steps:

1. Discover — Query available yield venues with current APYs to see where capital can be deployed.
2. Plan — Request a supply or unwind operation; RebelFi returns an unsigned transaction ready for signing.
3. Sign — The client signs using its own custody solution or wallet.
4. Submit and track — Submit the transaction hash for confirmation monitoring; Solana positions confirm in under 10 seconds.

Withdrawals are available on demand for standard positions, with no enforced lock-up periods. This matters for fintechs that need to preserve liquidity for settlement obligations.

Yield Architecture

RebelFi routes stablecoin deposits across four DeFi protocols selected by enforcing minimum TVL thresholds, a minimum 18-month protocol history, and dual independent security audits:

• Aave v3 — Overcollateralized lending on Ethereum and Base; described by the team as having processed over a trillion dollars in cumulative lending volume with no lender principal losses recorded.
• Morpho — Isolated market architecture reduces cross-market contagion risk; $4 billion-plus TVL at time of writing.
• Kamino — Solana-native lending protocol with $1.7 billion-plus TVL; the primary venue for Solana-based yield.
• Compound — Operating since 2018; the longest-running lending protocol in the set.

Yield is structured in two tiers. The standard tier, using overcollateralized lending via Aave, Morpho, and Kamino, targets 4–7% APY on USDC and USDT. The managed tier adds delta-neutral strategies and targets 7–11% APY. A Yield Router component queries live protocol rates, applies risk filters, and ranks options before any deployment.

A position monitor watches on-chain allocations and surfaces alerts when rates shift materially. An emergency exit procedure allows full portfolio withdrawal in a single transaction.

Programmable Payments and Smart Escrow

Beyond yield generation, RebelFi offers a Secure Transfers protocol for payment workflows that require more than a simple send. Funds can be locked into programmable escrow with conditional release logic: milestone-based triggers using verified external events, cancellation windows allowing senders to reverse before a recipient claims, and staged releases tied to delivery confirmation or other oracle-reported conditions.

This infrastructure targets B2B use cases including supplier invoice payments, trade finance, e-commerce buyer protection, and marketplace payment rails. Funds in escrow continue to earn yield while awaiting release conditions, which the team frames as a structural advantage over traditional escrow or wire-based payment flows.

Supported Assets and Chains

RebelFi supports USDC and USDT as primary assets. The platform operates across four networks: Solana, Ethereum, Polygon, and Base. Cross-chain orchestration is handled internally, allowing operators to accept deposits on any supported chain while RebelFi routes capital to the most favorable yield venues — which the documentation indicates is predominantly Solana-based through Kamino given speed and cost advantages.

Solana is highlighted explicitly for its transaction throughput and sub-cent transaction fees, which the team argues makes it viable for the high-frequency, small-denomination use cases common in payment infrastructure. A sandbox environment using Ethereum Sepolia testnet and simulated Kamino on Solana devnet is available for integration testing.

Target Customers

RebelFi is positioned squarely at institutional operators rather than individual users. Its stated sweet spot is fintechs with $5 million to $500 million per month in stablecoin volume — large enough to benefit from yield on float, but below the scale where direct DeFi integration becomes cost-justified. The fee model charges approximately 15% of gross yield generated (for example, $90,000 on $600,000 annual yield at $10 million deployed), with enterprise pricing available above $50 million in average deployed float.

The comparison against competitors — Ondo tokenized T-bills, Zero Hash custody and settlement infrastructure, and direct Aave integration — positions RebelFi on a combination of yield level and implementation speed. The platform claims a 2–4 week integration timeline versus 3–6 months for direct protocol integration.

Security Model

The security posture rests on several layers. Non-custodial design means the highest-risk component — private key management — remains entirely with the operator. Protocol selection enforces a minimum TVL threshold, an 18-month protocol age requirement, and dual independent security audits before a venue is made available through the router. Allocation limits cap exposure to any single protocol. For Solana-specific deployments, Kamino's $1.7 billion TVL and its native architecture on a high-throughput chain are cited as the primary justification.

No first-party audit of RebelFi's own smart contracts or SDK infrastructure was identified in available sources. The security framing in public documentation focuses on the underlying protocols rather than any audit of RebelFi's own code.

Team

No named founders or executive team are publicly disclosed on the RebelFi website or in its documentation. The project was founded in 2025 and presents as a developer-infrastructure business targeting institutional operators. An onboarding contact named "Alek" appears in Calendly scheduling links referenced in the documentation.

Solana Fit

RebelFi treats Solana as the primary yield execution layer. Kamino is the main Solana venue, and the documentation uses Solana-specific capabilities — sub-second confirmation, sub-cent transaction costs — as the core argument for why fintechs building stablecoin infrastructure should route through it rather than EVM chains. Solana devnet is part of the sandbox environment, and Solana mainnet is a live production deployment target alongside Ethereum, Base, and Polygon.
