PUBLIC DEMO · BROWSER-ONLY
SXP500 · BROKERLESS SYNTHETIC INDEX

BTC in. SXP out.
Simple as that.

SXP tracks the percentage movement of the S&P 500. No broker buys shares — matched collateral vaults settle gains and losses entirely on Solana, and every position stays fully collateralized on-chain.

What happens under the button

01

Collateral locks in

Test collateral is created in your demo vault. Nothing leaves your browser — every unit is valueless and resets on reload.

BROWSER-ONLY
02

SXP gets minted

SXP is minted only when matching opposing collateral exists. Long and short vaults mirror each other, so the system never prints unbacked exposure.

MATCHED VAULTS
03

Reference moves value

At settlement, the S&P 500 reference moves SXP between vaults via USDC. Winners are paid from the opposing side — no broker, no shares.

⚠ DEMO BOUNDARIES

  • Public demo · browser-only. This button uses valueless demo balances — nothing here has monetary value.
  • No wallet transactions. Connecting a wallet only creates a separate demo profile; no transaction will ever be requested.
  • Testnet only. The Solana synthetic program uses matched long/opposing vaults and does not purchase stocks.
  • No mainnet. SXP500 is a technical demo. The on-chain TEST BTC pool proves the route but is not Bitcoin and has no value.
  • Production path would require a separately reviewed BTC asset, market, bridge, external audit and legal clearance.
