Immute (IMT) is a bonding-curve reward token on the Sepolia testnet, which is an Ethereum test network. Version 6 LLC develops it. It is community testing only. It is not live on Ethereum mainnet.
The site says 10 percent of every buy and every sell is paid on-chain to holders. The token is non-custodial. The site also has live stats, a portfolio calculator, charts, an audit trail, and notes on the feeder contract.
Do not treat Immute as a mainnet exchange or as a promise of profit. Read the current pages on immute.io before you use the testnet contracts.
