what is sat protocol
Sat Protocol is a permissionless token launchpad on Ethereum. Anyone can deploy a new ERC-20 token with a Uniswap V4 pool in a single transaction. No coding required. Every launched token is recorded on-chain in the factory contract and gets its own trading interface automatically.
one-click deployment
Launching a token requires only a name, symbol, and an optional starting price tier. The factory deploys the token, creates a Uniswap V4 pool, seeds it with a one-sided liquidity position, locks the LP NFT, and mints a protocol agent NFT — all in one transaction.
fixed supply
Every token has a fixed supply of 1,000,000,000 (one billion) tokens. 100% of supply goes directly into the liquidity position. There is no team allocation, no pre-mine, and no reserved tokens.
uniswap v4 pool
Each token gets its own Uniswap V4 pool with a 1% fee tier. Liquidity is concentrated in a fixed tick range. The pool is initialized with a one-sided position — only tokens, no paired asset — so price starts at the chosen starting tick.
locked lp
The liquidity position NFT is transferred to the SatLocker contract at deploy time and locked for 2 years. This guarantees liquidity remains in the pool during the lock period. No rug pulls, no early liquidity removal.
protocol agent nft
Each deployment mints one protocol agent NFT. The holder of this NFT is entitled to receive 50% of all LP fees collected by that token's pool. The other 50% goes to the protocol. The agent NFT is freely transferable.
dev buy
When deploying, you can optionally send ETH above the deployment fee. The factory wraps the ETH and swaps it through the newly created pool, purchasing tokens for you at the starting price before any other buyers can act.
permissionless & immutable
Once a token is deployed, its contracts are immutable. No admin key, no upgrade proxy, no pause mechanism. The factory owner can only set the deployment fee and configure which paired tokens and price tiers are available.
