Quant Fusion is what is known as a multi-ledger rollup: a settlement layer that connects several blockchains at once instead of running on a single one. It has been on mainnet since June 2, 2026, and Quant Network states that it links 74 blockchain networks in one shared environment. The heart of the matter is not the number but a promise: a token that today sits in seven copies on seven blockchains is meant to appear in this environment as a single value with a single liquidity pool.
