BEX (Berachain DEX) is the native, protocol-level decentralized exchange built directly into the Berachain L1 blockchain — functioning as a standard constant-product AMM for swapping Berachain ecosystem tokens, deeply integrated with Berachain’s Proof of Liquidity (PoL) consensus so BEX LP positions in whitelisted pools earn BGT (Bera Governance Token) emissions, making BEX LPs simultaneously liquidity providers and consensus participants.
Overview
Unlike third-party DEXes deployed as smart contracts, BEX is a native Berachain protocol — one of three “native dApps” built directly into the Berachain L1 alongside BEND (lending) and BERPS (perpetuals). BEX’s privileged position as a native protocol means it receives first-class integration with Berachain’s Proof of Liquidity system: the BGT validators earn BGT emissions and “direct” them to designated rewardVaults, and BEX pools are among the first and primary candidates for BGT gauge status. LPs who provide liquidity in BEX whitelisted pools automatically earn BGT — non-transferable governance tokens that represent Berachain’s consensus participation.
Proof of Liquidity Integration
Berachain’s consensus mechanism is Proof of Liquidity (PoL), replacing traditional Proof of Stake:
- Validators stake BERA (Berachain’s gas token) to participate in consensus
- Validators earn BGT (Bera Governance Token) emissions as block rewards
- Validators must direct their BGT emissions to rewardVaults (protocol gauges registered with Berachain)
- BGT directed to a rewardVault is distributed to that vault’s LPs
- BEX pools are whitelisted rewardVaults → BEX LPs receive BGT
BGT Flywheel
- Validator earns BGT → directs to BEX pool rewardVault
- BEX LP receives BGT → holds BGT for governance or burns BGT for BERA
- BGT accumulation gives governance power → vote on which pools get more BGT
- High BGT rewards → more LPs deposit → more liquidity → better trading → more fees → attracts more LPs
This creates Berachain’s core economic loop: DeFi liquidity provision and consensus participation are unified.
BEX AMM Design
BEX uses a constant-product AMM (x × y = k) — similar to Uniswap V2 / SushiSwap:
- Standard token pair pools
- 0.25% default swap fee (governance can adjust per pool)
- Fungible LP tokens (ERC-20) representing pool share
- No concentrated liquidity at the native BEX level (CLMM is provided by third-party protocol Kodiak)
Supported Assets
BEX pools commonly include:
- BERA/HONEY — core pair (Berachain gas token vs native stablecoin)
- BERA/wBTC, BERA/wETH — BTC and ETH bridged to Berachain
- HONEY/USDC — stablecoin pair for HONEY price stabilization
- Ecosystem token pairs as Berachain native projects launch
HONEY Integration
HONEY is Berachain’s native overcollateralized stablecoin (CDP-based, minted via BEND collateral):
- BEX is the primary venue for HONEY ↔ BERA and HONEY ↔ USDC trading
- BEX HONEY pairs are typically among the highest-TVL pools
- HONEY peg maintenance depends partly on BEX arbitrage mechanisms
BGT Gauge Politics
Because BEX pools compete for BGT validator redirections, Berachain DeFi introduces a “gauge politics” layer similar to Curve/Velodrome:
- Validators choose which rewardVaults receive their BGT
- Protocols bribe validators to direct BGT to their pools (similar to ve(3,3) bribes)
- Infrared Finance emerged as a solution: liquid staking BGT (iBGT) and acting as a meta-validator directing BGT to optimal pools
BEX native pools typically receive priority BGT allocation due to their first-mover HONEY/BERA liquidity role in Berachain’s ecosystem health.
