THENA

THENA is the leading ve(3,3) decentralized exchange on BNB Chain, combining the Solidly vote-escrow gauge model with “Fusion” liquidity — a custom dual-pool system offering both classic Solidly-style constant-product pairs and concentrated liquidity positions managed by external managers — backed by the THE governance token and theNFT lock NFTs.

Overview

Launched in January 2023, THENA rapidly became BNB Chain’s dominant Solidly-fork DEX, accumulating hundreds of millions in TVL through aggressive bribe ecosystems and integrations with major BNB Chain protocols. By offering protocols a capital-efficient way to incentivize their own liquidity through THE token emissions, THENA built a deep partner ecosystem that created self-reinforcing demand for THE tokens. The theNFT lock system gives vote-escrow positions NFT form, enabling secondary market trading of locked positions.

THE Token and theNFT

THE Token:

  • Governance and emissions token
  • Locked THE creates veNFTs (theNFT) representing governance power
  • Lock durations from 1 week to 4 years
  • Maximum lock = maximum vote power

theNFT (veNFT):

  • ERC-721 NFTs representing locked THE positions
  • Transferable — locked positions can be sold on NFT marketplaces without unlocking
  • veNFT holders vote weekly on gauge emissions
  • veNFT holders earn 100% of trading fees from pools they vote for plus any bribes paid by protocols

This NFT-based lock system improves on Solidly’s original non-transferable veNFT approach by creating a liquid market for locked positions.

Fusion Liquidity

THENA’s Fusion liquidity system combines two pool types:

Classic Pools (vAMM / sAMM)

  • sAMM — stable AMM using Curve’s StableSwap invariant for correlated/pegged pairs
  • Direct descendant of Solidly’s original pool design

Concentrated Liquidity (CLMM)

  • Managed vaults — users deposit into managed positions and receive vault tokens rather than managing their own V3 ranges
  • Integrated with gauge system — concentrated liquidity pools can receive THE emissions voted by veNFT holders, same as classic pools

The dual system lets THENA serve both passive LP users (classic pools) and capital-efficient concentrated liquidity without requiring users to manage ranges themselves.

Bribe Ecosystem

THENA’s bribe market is central to its business model:

  • Protocol partners — DeFi protocols that want deep liquidity for their tokens pay THE or other tokens as weekly bribes to theNFT holders
  • veNFT voters — vote for pools where they receive the highest combined fee + bribe return
  • Optimal voting — sophisticated veNFT holders (or auto-voting tools) calculate which pools maximize weekly yield from fees + bribes
  • Self-reinforcing — as more protocols pay bribes, THE demand increases (veNFT buyers want bribes); as THE price rises, emissions become more valuable, attracting more protocol partners
