Chains WITHOUT Swap Support

The following chains exist in primitives::Chain but have no swap provider support:

Chain	Notes
Osmosis	Cosmos DEX ecosystem — Osmosis DEX is a major AMM
Fantom (Sonic)	SpookySwap, SpiritSwap; now Sonic with active DEXes
Sonic	Successor to Fantom, growing DeFi ecosystem
Sei	Parallel EVM chain with native DEXes (DragonSwap, Astroport)
Injective	Cosmos-based with Helix DEX, Dojos DEX
Celestia	Modular DA layer — limited DEX activity
Noble	USDC-native Cosmos chain — bridge/transfer focused
Mantle	EVM L2 — Agni Finance, FusionX DEX
Celo	EVM-compatible — Ubeswap, Curve
OpBNB	BSC L2 — nascent DeFi
Algorand	Tinyman, Pact DEXes
Polkadot	HydraDX, Stellaswap on Moonbeam
Abstract	New L2 — early ecosystem
Plasma	Limited DEX activity
XLayer	OKX L2 — emerging
Stable	Unclear DEX landscape

Expansion Opportunities

High Priority (established DEX ecosystems)

• Osmosis: Major Cosmos DEX — large TVL, IBC bridging
• Sei: Fast-growing EVM with DEX activity
• Injective: Active DeFi with Helix orderbook DEX
• Sonic (Fantom): Rebrand with active DeFi (Beethoven X, Shadow Exchange)
• Mantle: EVM L2 with growing DeFi TVL

Medium Priority

• Celo: Established EVM chain, Uniswap V3 deployed
• Algorand: Tinyman DEX has decent volume
• Polkadot: HydraDX omnipool

Provider Expansion for Existing Chains

• Add more Solana DEXes (Raydium, Lifinity)
• Expand Thorchain asset coverage (more ERC-20 tokens)
• Add Osmosis as cross-chain provider for Cosmos ecosystem
• Consider 1inch or 0x aggregator for broader EVM coverage

Asset Coverage Gaps

• More DeFi blue-chip tokens across chains (AAVE, MKR, CRV, LDO)
• Liquid staking tokens (rETH, cbETH, mSOL, bSOL)
• More stablecoin coverage on L2s
