## Summary

SailFish Finance is the first native veDEX on EDUCHAIN, allocating 100% of protocol fees to its community and supplying liquidity for EduFi. It combines vote-escrow (ve) mechanics and (3,3) game theory with concentrated liquidity and a smart split router.

SailFish Finance operates as a decentralized exchange (DEX) on EDUCHAIN that merges vote-escrow (ve) mechanics with (3,3) game theory to bolster decentralized finance (DeFi) activity. The protocol focuses on delivering liquidity specifically for EduFi use cases on EDUCHAIN.

## Overview

The platform is built to advance DeFi through concentrated liquidity provision, adaptive fee structures, and governance led by the community. As a veDEX, SailFish channels 100% of protocol fees back to its users and token holders. It supports farming targeted at concentrated liquidity pools and employs a smart split router intended to lower price impact during trades.

Departing from many conventional veDEX approaches that mandate extended token locks, SailFish permits holders to exchange $SAIL for $veSAIL without requiring a lock-up period. This model seeks to broaden participation and strengthen community-led governance. The design draws on Curve’s vote-escrow principles and OlympusDAO’s (3,3) game theory to pursue a sustainable, user-focused exchange on EDUCHAIN.

SailFish implements a "Singleton Vault" architecture that lets participants combine various actions—such as swaps, liquidity pool (LP) adjustments, voting, and reward claims—into a single atomic transaction. Allocation of $SAIL emissions to liquidity pools is decided by the community through $veSAIL-based governance.

## Key Features

SailFish integrates a set of core capabilities aimed at improving efficiency and user outcomes:

- Native Batch Transactions: Enables users to group multiple operations into one transaction to cut gas costs and streamline interaction.
- Fee-Sharing Rewards: Allocates 100% of protocol fees, inclusive of bribes, to participants on the SailFish platform.
- Smart Split Router: Acts as a DEX aggregator, splitting swaps across different routes to lower price impact and reduce trading fees.
- Fair Fungible Vote Token: Provides fungible voting tokens to maintain uniform lock conditions and permits immediate liquidation via the $SAIL/veSAIL pool.
- Concentrated Liquidity Pools: Supports farming specifically designed for concentrated liquidity pools.

## Technology

The technical stack behind SailFish combines established ve mechanics, cooperative incentive design, and routing and vault innovations:

- Vote-escrow (ve) Mechanics: Promotes locking tokens to obtain voting influence, share in fees, and receive stronger liquidity incentives.
- (3,3) Game Theory: Encourages cooperative behavior where staking and holding tokens together amplifies rewards and helps stabilize the protocol.
- Singleton Vault: Provides a construct that permits bundling several actions into one atomic transaction.
- Smart Split Router: Operates as a DEX aggregator that partitions swaps across multiple routes to reduce price impact.

## Tokenomics

SailFish employs a two-token model:

Holders are able to swap $SAIL for $veSAIL at any time without a lock-up requirement, and $veSAIL can be liquidated via the $SAIL/veSAIL pair on SailFish.

- $SAIL: An ERC-20 utility token used for rewards and liquidity incentives.
- $veSAIL: An ERC-20 governance token that enables voting on emissions and protocol adjustments.

## Use Cases

SailFish supports EDUCHAIN’s objective of bringing educational services on-chain by furnishing liquidity for EduFi projects, allowing EDUCHAIN applications to tap into on-chain liquidity to tackle education-related needs.
