By Prism
Prism is a live multichain DeFi hub — swaps, liquidity pools, perpetual futures, prediction markets, yield, and portfolio management — with 6,000+ organic users and $33M+ monthly volume since launching in March 2026. Selected into the Arbitrum Mentorship Program (13 teams from 900+ applicants), Prism is scaling beyond its early-adopter base into a broader consumer financial platform.
To get there, Prism needs what its current EVM stack alone cannot provide: institutional-grade settlement infrastructure, deep stablecoin liquidity, and regulated real-world asset integration. Stellar fills that gap. Its native SDEX, permissionless stablebond issuance by a regulated issuer (Etherfuse), and cross-chain USDC settlement via Circle CCTP V2 give Prism the financial infrastructure layer to offer sovereign bond yield that no EVM chain can replicate — multi-currency exposure (e.g., MXN, BRL, EUR bonds) whose deep liquidity sits on Stellar, not scattered across EVM AMMs.
The integration follows a three-step path:
1. Open cross-chain access
Circle CCTP V2
Cross-chain intents (e.g., NEAR Intents)
NEAR Chain Signatures
2. Integrate yield infrastructure
SDEX
Soroswap Aggregator
Blend
Etherfuse stablebonds
3. Make it feel native
DeFindex
Reflector
SEP-10
Stellar Wallets Kit
Stellar RPC
These twelve Stellar ecosystem components are packaged into two consumer-facing products.
A POC is already live, with the full product interface deployed and a functional Stellar wallet integration on testnet:
https://stellar.prismfi.cc/earn
Product 1 — One-click Stablebond Access
One-click USDC deposit from any EVM wallet into Stellar-native sovereign bond yield.
Flow:
Circle CCTP V2 for USDC settlement
Cross-chain intents for execution
Stablebonds acquired permissionlessly on the SDEX
Larger orders routed through Soroswap Aggregator (SDEX, Soroswap, Aquarius)
Idle USDC deployed on Blend until execution
Stellar acts as the settlement, trading, and asset layer.
Impact
Brings an existing EVM user base onto Stellar rails weeks after CCTP's launch
Unlocks multi-currency sovereign exposure (MXN, BRL, EUR bonds) whose liquidity exists primarily on Stellar
Product 2 — Automated Stablebond Vault
A custom Soroban strategy built on DeFindex's vault framework, aggregating stablebond exposure with automated compounding and open-sourced post-launch.
Stellar acts as the DeFi strategy layer.
Impact
Routes TVL into the SCF-funded composability stack
Leverages DeFindex vaults and Blend liquidity infrastructure
Adds a reusable open-source yield strategy to the ecosystem
Revenue & Sustainability
Prism monetizes through yield-generated fees rather than principal-based fees:
Performance fee on the DeFindex strategy
Blend Fee Vault revenue on idle yield
Fees are intentionally kept low to maintain competitive net returns.
The entire model is implemented through native Stellar frameworks and on-chain mechanisms, requiring no custom billing infrastructure. This allows the module to remain self-sustaining post-grant with near-zero marginal cost while continuously routing new TVL, trading volume, and active users into the Stellar ecosystem.
$124.6K
Prism launched in March 2026 and onboarded 6,000+ users in its first three months with zero paid acquisition. During that period:
Monthly volume grew from $6.95M (March) to $33.3M (May)
TVL peaked at $4M
Monthly revenue reached $10k–15k
Protocol fees grew from $12,984 (March) to $43,523 (May)
Prism was selected into the Arbitrum Mentorship Program, with only 13 teams chosen from more than 900 applicants:

Most funded integrations face a cold-start problem after launch. Prism does not. The Stellar integration will launch to an existing base of 6,000+ users and benefit from immediate amplification through Prism's established distribution network. The award funds the build; the audience already exists.

Brief description
Implement the production deposit flow behind the deployed interface: one-transaction USDC deposit from an EVM wallet to a Stellar account via cross-chain USDC routing, including canonical burn-and-mint routing (e.g. Circle CCTP V2) and cross-chain intents (e.g. NEAR Intents), with backend route selection, error handling, retry logic, and transaction status tracking.
How to measure completion
A user can deposit USDC from an EVM wallet and receive it on a Stellar account from a single signed transaction, demonstrated in staging through a recorded flow over one routing path.
Estimated date of completion
End of August 2026
Budget
$14,200
Deliverable 2 — Stellar wallet connectivity and SEP-10 sessions
Brief description
Add native Stellar wallet support in the Prism interface through standard ecosystem wallet libraries such as Stellar Wallets Kit, with priority support for major wallets such as xBull and Freighter. Implement SEP-10 web authentication to issue persistent sessions tied to Stellar accounts, enabling portfolio access across user sessions.
How to measure completion
Users can connect a supported Stellar wallet, authenticate via SEP-10, view balances, and sign transactions directly from the Prism UI in staging.
Estimated date of completion
End of August 2026
Budget
$8,400
Deliverable 3 — RWA yield position engine
Brief description
Implement position accounting for tokenized sovereign stablebond holdings, such as Etherfuse assets, within Prism's existing portfolio engine. This includes balances, accrued yield through issuer redemption values, multi-currency display using FX feeds such as Reflector, and transaction history.
How to measure completion
A staging user can view a Stellar yield position with accurate balance, accrued value, and transaction history in their Prism portfolio.
Estimated date of completion
Early September 2026
Budget
$4,400
Brief description
Deploy the complete user journey in a test environment, combining Stellar testnet and staging infrastructure for the cross-chain layer. The flow includes EVM USDC deposit, Stellar settlement, permissionless stablebond acquisition on the SDEX (e.g. Etherfuse), and portfolio tracking within Prism.
How to measure completion
External testers can successfully complete the full deposit and earn flow in the test environment. A complete demo is recorded and shared with reviewers.
Estimated date of completion
End of September 2026
Budget
$16,200
Deliverable 2 — Redemption, aggregator routing, and idle yield
Brief description
Implement the full exit path, including stablebond redemption on the SDEX and withdrawals to either a Stellar wallet or an EVM wallet through the routing layer. Integrate large-order routing via the Soroswap Aggregator (across venues such as SDEX, Soroswap, and Aquarius) and an optional idle-yield mechanism supplying pending-allocation USDC to a lending market such as Blend.
How to measure completion
An external tester can execute the complete lifecycle (deposit, earn, redeem, withdraw) within the test environment. Aggregator routing and idle-yield functionality are demonstrated where liquidity is available.
Estimated date of completion
Mid-October 2026
Budget
$16,300
Deliverable 3 — Position history indexer and portfolio integration
Brief description
Build an internal indexing service that captures relevant Stellar ledger events and stores them within Prism's infrastructure, enabling durable position history beyond RPC retention limits. Integrate indexed data into Prism's existing multichain portfolio dashboard.
How to measure completion
Positions, balances, and transaction history display consistently across sessions and accurately reflect on-ledger activity within the test environment.
Estimated date of completion
Mid-October 2026
Budget
$9,200
Brief description
Deploy the Stellar earn module to production within the live Prism application, including deposit, yield generation, portfolio tracking, and redemption functionality. The module will be publicly accessible and available to all Prism users.
