StableSwap (deprecated)

Deprecated Saddle-style stableswap pools

Status: deprecated. No longer surfaced in the dApp's primary UI.

Last updated: July 6, 2026.

What it was

StableSwap was Alien Base's deployment of Saddle-style (Curve-derived) stablecoin AMM pools, listed as a separate protocol on DefiLlama. It was designed for low-slippage swaps between same-asset variants (e.g., stablecoin↔stablecoin, ETH↔cbETH, BTC↔cbBTC).

It launched as one of several attempts to specialize liquidity for tightly-pegged assets without forcing them through a generic V2 or V3 pool. In practice, it never gained meaningful TVL — Alien Base V3 supports dedicated low fee tiers (0.01% / 0.02% for stables, 0.03% / 0.04% for LSDs and very-blue-chip volatile pairs, 0.075% for ETH/BTC) which serve the same use case more efficiently and with better composability.

Why it was deprecated

  • TVL never grew to a level that justified maintenance overhead.

  • V3 with the 0.01% / 0.02% / 0.03% / 0.04% / 0.075% fee tiers handles the same pairs more efficiently.

  • DefiLlama still lists "Alien Base StableSwap" as a separate protocol entry, but the pools have minimal current activity and aren't featured in Alien Base's UI.

Contracts

The Saddle-style SwapFlashLoan pool contract is at 0x927860…bb27 — see the Contracts — Deprecated section.

If you have funds in StableSwap

Pools remain on-chain and remain functional. To withdraw:

  1. Identify the specific StableSwap pool you deposited into.

  2. Call removeLiquidity(...) (or remove_liquidity_one_coin for single-asset withdrawal in Saddle-style pools) on the pool contract directly via Basescan.

  3. If your LP is staked, withdraw(...) from the gauge / farm first.

If you can't figure it out, post in Discord — the team can walk you through it.
