what's TAT Protocol?

TAT Protocol is a Bitcoin-native standard for memecoin launches and trading, developed by Saturn Terminal. Tokens are created with an OP_RETURN genesis transaction on Bitcoin mainnet. Trading occurs via a custodial constant-product automated market maker (CPAMM) layer denominated in satoshis, enabling instant swaps with virtual initial liquidity (e.g., 0.3 BTC + 1.073B tokens). A flat 1% fee applies with zero creator tax; trade receipts and balances are Merkle-anchored to Bitcoin for full auditability. Successful tokens graduate to native Bitcoin Runes protocol upon reaching 0.5 BTC market cap threshold. Integrated into Saturn Terminal's trading platform (supporting BNB, Solana, Bitcoin), it brings memecoin functionality to Bitcoin without requiring sidechains or L2s, leveraging OP_RETURN for on-chain permanence and off-chain execution for speed.
