Ring Swap Contract Deployments
This is the maintained address directory for Ring Swap, FewFactory, routers, wrappers, and related contracts. Some
partner integrations and older tooling call this deployment family FewV2. The product name in these docs is Ring
Swap (v2).
This page was revised on 2026-08-20. It is a versioned documentation snapshot, not a live registry or a substitute
for onchain verification. Addresses are chain-specific. Select the network before copying an address, check that it has
bytecode, and validate the contract's immutable factory, FewFactory, WETH, or wrapper references where applicable.
Both reference pages cover Ethereum (1), BNB Smart Chain (56), HyperEVM (999), and MegaETH (4326). Pool
addresses and discovery notes are documented separately in Pools by Network.
UniversalRouter rows are published Ring routing endpoints. Do not infer that every Interface, API, or route uses that
address. Select the execution flow first and allow only the router approved for that flow.
Ring-published hook addresses used with external Uniswap v4 infrastructure are documented separately under
Few Hook Contracts.
Addresses are not deposit destinations
Do not transfer assets directly to a Factory, Pair, Router, FewFactory, FewToken, wrapper, hook, or Permit2 contract.
Call the documented function through a reviewed integration. A listed address does not by itself establish an approval
spender, token endorsement, audit result, current liquidity level, or redemption guarantee.
Before a transaction, use the Security and Risk checklist. Verify the chain ID, code, recipient,
raw amount, token path, spender, deadline, price limit, and simulation result.
