Usual is a DeFi bank deployed across four chains. This article covers where each product lives, what the trade-offs are between chains, and how to pick the right one for your use case.
Supported chains at a glance
Chain | USD0 | bUSD0 | USUAL | USUALx | EUR0 | ETH0 |
Ethereum | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ |
Arbitrum | ✅ | ✅ | — | — | — | — |
Base | ✅ | — | — | — | — | — |
BNB Chain | ✅ | — | — | — | — | — |
Ethereum is the primary deployment — every product is live there. Other chains have a focused subset optimized for cross-chain liquidity and low gas.
Chain-by-chain
Ethereum
Why Ethereum:
Deepest liquidity across every Usual product
Highest security (most decentralized and battle-tested execution layer)
All governance and staking happens here
Widest ecosystem of DeFi integrations
Trade-offs:
Gas fees are the highest among supported chains
Some routine operations (staking, claiming) are more expensive than on L2s
Best for: governance, locking into USUALx, large transactions, and integrations with Ethereum-native protocols.
Arbitrum
Why Arbitrum:
Low gas fees
Large DeFi ecosystem
Strong USD0 liquidity
Trade-offs:
USUAL, USUALx, EUR0, and ETH0 are not native here — they live on Ethereum
Bridging is required to move balances in and out
Best for: USD0 transactions, integrations with Arbitrum-native DeFi apps, and active trading.
Base
Why Base:
Very low gas fees
Coinbase Smart Wallet support (easy on-ramp for new users)
Growing ecosystem
Trade-offs:
Only USD0 is live here
Liquidity is still building
Best for: new users coming from Coinbase, small transactions, early ecosystem participation.
BNB Chain
Why BNB Chain:
Low gas fees
Large user base (Binance ecosystem)
Good stablecoin liquidity
Trade-offs:
Only USD0 is live here
Fewer DeFi integrations than on Ethereum or Arbitrum
Best for: users in the BNB Chain ecosystem, Binance withdrawals directly into USD0.

How to pick a chain for your use case
Your goal | Chain |
Maximum security for large balances | Ethereum |
Governance (voting, staking, locking) | Ethereum |
Low-cost USD0 transactions | Arbitrum, Base, or BNB Chain |
Coming from Coinbase | Base |
Coming from Binance | BNB Chain |
Deepest DeFi integrations | Ethereum |
Multi-chain expansion
Additional chains may be added through governance. New collateral types, new regions, and new products often start on Ethereum and expand later as liquidity builds.
The canonical deployment roadmap is maintained in the docs. When a new chain is approved, it is announced through the usual channels (blog, governance forum, X, Discord).
Note: USUAL, USUALx, EUR0, and ETH0 live only on Ethereum. If you want to stake, vote, or hold euros or ETH0, you need to be on Ethereum.
Technical note (for DeFi users): All Usual deployments are native — no wrapped tokens, no synthetic representations. Cross-chain bridging uses Chainlink CCIP and LayerZero as the technical stack. Each chain's deployment is a separate contract with its own admin structure, coordinated through DAO governance. See the docs for the complete deployment registry.
