Contracts on Base
Flowlex opens and manages liquidity positions on Base mainnet, chain ID 8453. The addresses below identify the contracts used in that flow. Each link opens the contract on BaseScan.
To add funds, use the personal wallet address shown in Flowlex. Do not send tokens directly to the position manager, pool, router, token contracts or wallet infrastructure listed here. These are integration addresses, not your deposit address. Your Safe smart account has its own address.
Flowlex position manager
0xe20435ac8160aa58adea4a1fc5641bb5adaed053
Flowlex's BetaLPManager coordinates opening positions, collecting trading fees, closing positions and rebalancing. Tokens can pass through it while an operation executes. The transaction returns unused tokens and proceeds to the calling wallet, while the position NFT belongs to that wallet. It is designed to operate as a transaction helper without retaining customer deposits between operations.
Available balances and position NFTs belong to your Safe smart account. Tokens allocated to an active liquidity position are in the Uniswap pool, represented by the NFT owned by your Safe. See wallets and ownership and the transaction lifecycle.
The contract address and its settings were checked on 24 October 2026, at Base block 53,040,820. At that block, all four Flowlex service-fee settings were 0%, and the manager held no USDC, WETH or Uniswap position NFTs. These are observations at that block, not a continuous balance or fee guarantee. The fees guide explains which other costs may apply.
Address checks are separate from source-code verification. The deployed address and its configuration were checked against the deployment record and blockchain data; the manager's source code was not verified on BaseScan at the time of this review. An explorer link by itself is not an audit or a security certification.
Uniswap position manager
0x03a520b32C04BF3bEEf7BEb72E919cf822Ed34f1
Uniswap V3's NonfungiblePositionManager creates and manages the NFTs that represent liquidity positions. Your Safe owns its position NFTs; the Flowlex manager requests the permissions needed to perform the action you authorize.
Uniswap swap router
0x2626664c2603336E57B271c5C0b26F421741e481
SwapRouter02 performs swaps used to prepare the token balance for a position or convert proceeds. A swap can incur pool fees and price impact even when Flowlex's service fee is zero.
Uniswap pool factory
0x33128a8fC17869897dcE68Ed026d694621f6FDfD
The Uniswap V3 factory creates pools and identifies their addresses for a token pair and fee tier.
Default WETH/USDC pool
0x6c561B446416E1A00E8E93E221854d6eA4171372
The standard Flowlex strategies use this WETH/USDC pool. Its 0.3% fee tier is the pool's trading fee, separate from Flowlex's 0% service fees. It is not an annual return or a fee on the total value of your position. Eligible liquidity can earn a share of trading fees while it is in range.
Flowlex Pro may offer other eligible pools. Check the selected pool and transaction details before confirming; this default-pool address is not a list of every pool available in Pro.
USDC
0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
Circle's native USDC token contract on Base. USDC contracts on other networks have different addresses. This address identifies the token; it is not an address to which you should send a deposit.
WETH
0x4200000000000000000000000000000000000006
Wrapped Ether on Base, the other token in the default pool. WETH is an ERC-20 representation of ETH; a WETH balance and a native ETH balance are distinct.
Smart-account infrastructure
These shared contracts help execute supported Safe account transactions. They are not your personal wallet, and they do not identify the owners or permissions of a particular account. Account configuration can vary; inspect your own Safe for its owners and enabled modules.
Safe 4337 module
0x75cf11467937ce3F2f357CE24ffc3DBF8fD5c226
Safe's account-abstraction module used by the current external-wallet integration. It connects the Safe to the ERC-4337 transaction flow.
EntryPoint
0x0000000071727De22E5E9d8BAf0edAc6f37da032
The EntryPoint contract used by that integration processes ERC-4337 user operations. A bundler submitting an operation does not become the owner of your Safe.
Reference sources
The third-party addresses can also be checked against Uniswap's Base deployment list, Circle's USDC contract list and Safe's published module deployment record.
