RWA & Tokenization

Crossyield

Crossyield is an MIT-licensed cross-chain RWA integration scaffold comprising a web dashboard, Ethereum Solidity contracts, and an Anchor-compatible Solana vault program. Its described flow locks allowlisted ERC-20 assets on Ethereum, records NAV from Chainlink, publishes a Wormhole-attested deposit, and credits a vault position on Solana. The program also includes harvest and redemption paths.

Practical overview

When it fits

Use it when exploring or developing an integration scaffold for tokenized-asset deposits from Ethereum to Solana, including VAA handling and vault-share accounting.

Who it is for

  • Developers examining or adapting an Ethereum-to-Solana tokenized-asset deposit flow.
  • Vault builders working with cross-chain attestations, share accounting, and yield-harvesting interfaces.

Documented uses

  • Inspect how an Ethereum deposit is represented in a Wormhole payload and credited to a Solana vault position.
  • Review dashboard fields for NAV, share price, and pending VAAs.
  • Run the documented EVM and Solana local test commands.
  • Study the scaffold's harvest, redemption, and duplicate-message handling interfaces.
Before you choose

Requirements & limits

The repository is public and identifies an MIT license. Its README says keys stay in `.env` and the default path does not perform live signing.

  • Ethereum-side deposits use an allowlisted asset and a Chainlink NAV feed.
  • Solana deposits require a verified Wormhole PostedVAA; the program records processed messages to prevent duplicate sequences.
  • The dashboard is a separate web component, while deposit, harvest, and redemption logic resides in contracts and the Solana program.
  • The README says production use requires a production Wormhole core-bridge program and relayer; the described cut is an integration scaffold and is not audited.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Run the documented local checks

Run the repository's EVM contract tests and Solana program unit checks.

Before you start

  • A local clone of the public CrossYield repository.
  • Foundry for the EVM test command and Cargo for the Solana program test command.

Steps

  1. In the repository, change to packages/evm-contracts and run forge test -vv.

  2. Change to programs/crossyield-vault and run the command below.

    Documented command
    cargo test

Expected outcome

The documented local test commands are run for the EVM contracts and Solana program.

Guide limitations

  • These are documented local checks, not evidence of production deployment or security auditing.
  • The default path is paper or dry-run only and does not perform live signing.
