Built for those who refuse to ask permission.
SE1 — the sovereign way to exchange — is a non-custodial swap and bridge interface aggregating the best routes across decentralised markets on every supported blockchain — EVM networks, Solana, native Bitcoin and the XRP Ledger — with a clear gold standard for fees and transparency.
Your keys, your trade. SE1 never custodies funds.
Aggregated price discovery across the deepest liquidity on every supported chain.
Add chains, tokens, and integrations without friction.
How SE1 works
Five simple steps from wallet to settlement.
Connect using:
- MetaMask
- WalletConnect compatible wallets
- Coinbase Wallet
- Trust Wallet
- Rabby Wallet
- Other supported Web3 wallets
You always remain in control of your funds.
Select the blockchain network you want to use, including:
- Base
- Ethereum
- Polygon
- Arbitrum
- BNB Chain
- Solana
- Bitcoin (native BTC — send & receive)
- XRP Ledger (native XRP — send & receive)
Additional networks may be added over time.
Choose the assets you wish to exchange.
SE1 automatically searches available liquidity sources to find competitive pricing and routes for your trade.
Move supported assets between different blockchain networks without using a centralized exchange.
Examples:
- Base → Polygon
- Ethereum → Base
- Arbitrum → BNB Chain
- Base ⇄ Solana
- Ethereum ⇄ Solana
- Ethereum / Base / Polygon / Arbitrum / BNB → native Bitcoin
- Ethereum / Base / BNB ⇄ native XRP (XRP Ledger)
Cross-chain transfers allow you to access opportunities across multiple ecosystems while keeping control of your assets.
SE1 is a non-custodial platform.
Your assets remain in your wallet at all times.
SE1 never takes custody of user funds.
Bitcoin support
SE1 supports Wrapped Bitcoin (WBTC) on supported blockchain networks.
WBTC is designed to track the value of Bitcoin and allows Bitcoin exposure across smart contract networks.
Users can swap into WBTC and bridge supported wrapped Bitcoin assets between supported chains.
Additional Bitcoin-related integrations may be added in future updates.
Why use bridging?
Bridging allows assets to move between blockchain networks.
Examples:
- USDC on Base → USDC on Polygon
- ETH on Ethereum → ETH on Base
Benefits include:
- Accessing different ecosystems
- Lower transaction costs
- Additional liquidity opportunities
- Cross-chain flexibility
