Access and swap routes.

Base is the initial external liquidity and routing domain. LESOU/Base and native L3 LESOU are independent assets. A route definition does not mean execution is active. The website does not connect wallets or execute transactions.

Access: Base and LeSou L3

Start on Base. If your assets are on Ethereum, use a supported route to Base first. Check the network and destination before sending.
Obtain LESOU/Base when it exists. The planned entry market is LESOU/Base ↔ USDC. Verify the published token contract and pool identity before trading. LESOU/Base is not deployed.
Use a published route to L3, when one is verified. Native L3 LESOU is not a wrap of LESOU/Base and is not automatically redeemable for it. ETH pays gas on both networks.
Enter a token market on L3. Launched tokens may pair with native L3 LESOU. Review the pool, token restrictions, quote, fees and slippage before confirming.

These are separate transactions. A failed later step does not reverse earlier ones. No founder-funded LESOU pool on Ethereum is planned.

Swap: two Base routes, one LESOU/Base pool

The planned wrapper reaches the same LESOU/Base ↔ USDC pool through either native Base USDC or ETH via existing WETH/USDC liquidity. An L3 trade and a Base swap are separate operations.

Route	Path	Required checks
USDC ↔ LESOU/Base	Native Base USDC ↔ LESOU/USDC	Verified pool, adapter, executor and fresh quote
ETH ↔ LESOU/Base	ETH/WETH ↔ existing WETH/USDC liquidity ↔ LESOU/USDC	The same checks, external liquidity and wrap/unwrap support
Exchange funding	Withdraw USDC on Base to your own wallet, then approve a separate fresh quote	Account and regional support, correct network and Base ETH for gas
L3 LESOU ↔ LESOU/Base	Independent native L3 LESOU ↔ LESOU/Base via a published inventory route	Both contracts, inventory, executor, and fresh quote. Not a wrap or peg. Execution stays off until verified

Fees and safeguards

The optional wrapper is specified to charge 0.25% once, in USDC, at the LESOU/Base pool boundary. For a gross basis of 100 USDC, that is 0.25 USDC. Pool, network and external withdrawal fees are separate. Wallet connection, approval and exchange withdrawal do not incur a LeSou routing fee.

Only exact-input orders are specified. Quotes expire after 60 seconds; default slippage is 0.50% and the maximum is 1%. Quotes with estimated price impact above 10% are rejected. These controls do not guarantee execution or price.

A completed on-chain swap is atomic: a failed leg, fee transfer, refund or ETH delivery reverts it. Gas spent on a failed transaction or earlier approval is not returned. Exchange withdrawals and L3 routes are separate journeys and are not reversed by a failed later swap.

Do not send LESOU directly to an exchange deposit address. No exchange listing, partnership or tested connector is implied. Verify asset identities, and download the complete route specification.
