MetaFlux 0.8.0 — Testnet relaunched from a fresh genesis, with stricter liquidation and oracle safeguards

Fresh genesis — Chain ID 114514, live from 2026-07-26 21:15 UTC. This release relaunches the MetaFlux testnet from a new genesis, so all previous chain data is discarded: balances, positions, orders and history do not carry over. Claim test USDC and MTF from the faucet to start again.

Risk and liquidation — Liquidation now cancels every resting order that could increase an account's exposure, on all liquidation tiers. Previously only post-only orders were cancelled, so a resting limit order could fill mid-liquidation and move the very position the engine was closing. Reduce-only orders are kept through a liquidation, so an account never loses its own exit. Position mode can no longer be switched while a TWAP parent is live — the switch used to leave the parent to fail slice by slice.

Markets and open interest — Open-interest ceilings now apply to native markets; a governance-set cap previously enforced nothing outside builder-deployed markets. An order at the cap that can only reduce a position is always admitted, so a cap never blocks an exit. Orders for markets that do not exist are rejected, where they previously created a permanent empty order book.

Oracle — Self-priced markets now require real two-sided depth before their book mid may set an index price. A market that does not meet the requirement is marked stale, and margin, funding and liquidation defer for it rather than acting on an untrustworthy price. The depth, band and move-limit values are governance-tunable.

Transfers — Core-to-EVM transfers reject any asset the EVM side cannot credit as its own token, and both transfer entry points now apply the same rule.

Self-trade prevention — A parent account and its sub-accounts share one self-trade-prevention group on the order book, matching the behaviour already applied to RFQ and auction orders.

Consensus — A node restarting from its write-ahead log no longer re-releases a vote for a block it did not originally sign.

Markets at launch — Five markets, each available as a perpetual, as a spot pair quoted in USDC, and on margin: BTC and ETH at 100x, SOL at 50x, MTF at 25x, and PUMP at 10x. Those figures are the base ceiling — position size tiers may require more margin than the headline leverage suggests.

Deposits — USDC deposits go through MetaBridge on Base Sepolia and Arbitrum Sepolia. Both a contract deposit and a plain USDC transfer to the custody address credit the sender. Deposit tracking starts from the current chain head, so transfers sent before launch are not picked up.
