## What it is
Sea Protocol is a decentralized exchange (DEX) protocol combining order-book and AMM trading, implemented in Move on the Aptos and Sui blockchains, with an EVM version (GridTrade) on chains like BNB Smart Chain. It supports advanced order types such as grid orders that automatically flip between buy and sell as prices fluctuate, plus zero-spread post-only orders for stablecoin swaps.

## Use cases
- run automated grid trading strategies on-chain
- trade any asset on a decentralized order-book DEX
- swap stablecoins with zero spread
- provide AMM liquidity on Aptos and Sui
- query grid orders and trading pairs via REST API
- deploy a decentralized exchange on high-throughput blockchains

## When to choose
- you need on-chain grid trading with automatic order flipping
- you want a DEX on Aptos or Sui leveraging parallel execution
- you need zero-spread stablecoin trading pairs
- you want fully decentralized, non-custodial trading

## When to avoid
- you need a simple token swap without order-book features
- you require chains other than Aptos, Sui, or supported EVM networks
- you need a custodial or centralized exchange solution
- you need guaranteed regulatory compliance or KYC
