INDEX BASKET PROTOCOL·SOLANA DEVNET

One token.
The whole thesis.

Fulcron compiles weighted, leveraged baskets of stocks, ETFs and crypto into single SPL shares. The weights sit on-chain like loads on a beam — every leg exactly where the strategy put it, rebalanced around one fixed point.

The strategy is the token.

ERC-4626 vault shares

Pick two to eight legs — stocks, ETFs, crypto — set the weights in 5% cells, choose a target from 1.0× to 3.0×. The factory compiles them into one SPL vault share: mint it, hold it, transfer it, redeem it. There is no separate claim to sign — the exposure you see is the exposure you hold.

Four moves.
No discretion.

the whole operation set
01 Compose 2–8 legs, Σ|w| = 100%, leverage 1.0×–3.0× — the factory refuses anything outside the bands. $ compose --cells 5% 02 Mint Wrap SOL, deposit WSOL, shares strike at NAV — no lockup, no whitelist, entry 10 bps. $ mint --at NAV 03 Keep A 0.25× drift from target lets anyone rebalance for a bounty; one stale oracle leg halts the whole floor. $ keep --band ±0.25× 04 Redeem Burn any amount at NAV, any time — exit terms declared at mint, only ever improving. $ redeem --at NAV

Leverage has bounds.

synthetic exposure · hard-coded bands

Exposure is synthetic — underwritten by a counterparty pool and measured from NAV and margin on every health check. The bands are hard-coded: drift calls a rebalance, the ceiling calls anyone.

Three seasons.

v0.2 · testnet MVP
LIVEPHASE 01

Testnet MVP

One non-upgradeable Anchor program on Solana Devnet, eight demo baskets, twelve mock feeds on a 300 s heartbeat, permissionless rebalances with bounties.

PHASE 02

Depth

Short weights, liquidation incentives, fuzz and simulation reports published with the paper, Chainlink stock and ETF feeds mapped to the registry.

PHASE 03

Mainnet review

Compliance assessment, audited contracts, position limits ramp — and the $FUL utility evaluated against the checklist before anything ships.

Straight answers.

the rest live on the Paper
Q·01What exactly do I hold?+
An ordinary SPL token — the share token of one basket vault. Minting strikes it at NAV, redeeming burns it at NAV, and in between it is transferable, listable and composable like any token. The weighted, leveraged strategy is the token.
Q·02Where does the leverage come from?+
From a counterparty pool, not from borrowed assets. Exposure is synthetic: the pool underwrites it against margin, and actual leverage is measured from NAV and margin on every health check. A 0.25× drift triggers a permissionless rebalance; 3.25× triggers emergency deleverage — anyone may call either, for a bounty.
Q·03What if an oracle goes stale?+
Every feed must beat a 300-second heartbeat (testnet value). The moment any leg goes stale, the whole floor halts — mints, redeems and rebalances included — until freshness returns. Failure is designed to be loud and total, never partial or quiet.
Q·04Can the terms change after I mint?+
Weights, bands and exit terms are declared at minting and immutable afterwards. Governance can only narrow parameters within hard caps — it can never widen fees, raise leverage past the ceiling, or touch your redemption at NAV.
