LST Token Standards & Metadata Schema

Refract’s pxLST tokens are designed for maximum composability, transparency, and reliability. Every branded token follows SPL standards and includes embedded metadata that maps the token to its origin strategy, validator logic, and platform backend.

SPL-Standard Compliance Each pxLST is implemented as an SPL token, enabling native compatibility across the Solana DeFi ecosystem. This ensures seamless usage in DEXes, LPs, lending markets, vaults, and bridges.

On-Chain Metadata Mapping Every pxLST is linked to a metadata account that includes:

• Strategy ID (on-chain route)

• Backend source (e.g. Jito, Marinade, Blaze)

• Validator group or hash ID

• Mint time / epoch reference

• APY tracking hooks (optional for analytics)

Frontend Display & Verification Frontends and explorers can use these metadata fields to:

• Show yield origin clearly (e.g., "Powered by Jito")

• Display validator or strategy-level performance

• Validate token authenticity (vs spoofed LSTs)

Interoperability Enhancements Refract metadata is designed to be compatible with cross-chain wrappers like LayerZero OFT metadata or Wormhole token descriptors. This ensures pxLSTs maintain traceability and composability when bridged.

Security Checks Tokens include internal reference hashes to detect tampering, invalid routing, or unauthorized minting. Validators and off-chain monitors can reject unregistered or malicious pxLSTs based on the metadata schema.

With standardized metadata, pxLSTs become more than just yield-bearing tokens — they become reliable building blocks for DeFi strategies, composable vaults, and cross-chain staking products.
