Prism Earn · preview POC

Stablebond yield from one Prism deposit

This page previews the target Earn experience. The deposit, bridge, and allocation flows are not live yet — scroll to the Stellar sandbox below for the working testnet integration (wallet, balances, payments).

Stellar-native product

Built on Stellar mechanics, not just Stellar branding

Prism Earn is designed around Stellar account reserves, trustlines, issued assets, path payments, and sponsorship. The integration demonstrates each layer with live Horizon reads and real transaction building.

Architecture doc

Stellar accounts, not opaque custody

Each user maps to a real Stellar account with issued-asset balances. Prism can sponsor reserves and fees so users never manage XLM manually.

Native Circle USDC settlement

Bridged deposits settle as Circle USDC on Stellar — the same settlement asset Etherfuse and Stellar DeFi expect.

Etherfuse stablebonds on Stellar

USTRY and future markets are Stellar issued assets with trustlines. V1 avoids custom Soroban bond contracts.

Path payments for allocation

USDC → USTRY allocation uses Stellar path payments and/or Etherfuse ramp orders, surfaced as a simple Earn market.

Step 1

Deposit USDC

Start from the user's regular Prism EVM wallet. Native Stellar wallet connect remains available for Stellar-native users.

Step 2

Bridge to Stellar

Route EVM USDC into Stellar settlement through CCTP V2 where possible, or NEAR Intents for broader chain and asset coverage.

Step 3

Allocate to stablebonds

Swap Stellar USDC into Etherfuse stablebonds and show the resulting position inside Prism Earn.

Etherfuse bond selection

Choose your stablebond market

Prism Earn surfaces Etherfuse stablebonds as simple yield markets, starting with USTRY and expanding into multi-currency sovereign exposure.

No paths returned for this amount. Try a different USDC input.

Production allocation combines this Stellar path payment model with Etherfuse ramp orders where needed. The demo proves we are building against real Stellar liquidity paths, not mock yield numbers.

EVM-first access

Use Prism without installing a Stellar wallet

The target flow uses the user's existing Prism EVM wallet while NEAR Chain Signatures enables non-custodial Stellar execution behind the scenes. Users should not need Freighter or xBull for the mainstream Earn path.

Account model WIP

NEAR Chain Signatures inspector

Engineering surface for the EVM-first path: derive a stable Stellar Ed25519 account path, hash unsigned XDR, and prepare the MPC signature payload NEAR Chain Signatures will sign.

Paste a valid unsigned testnet XDR to inspect the Chain Signatures signing payload.

Strategy layer

DeFindex strategies

DeFindex aggregation can sit on top of the stablebond route once the core Stellar settlement and Etherfuse allocation flow is live.
