@TelcoinTAO has added a swap feature to TELx, its liquidity dashboard, allowing users to trade tokens without leaving the platform. Previously, liquidity providers had to use an external exchange first, then return to TELx to join a pool and earn rewards.

Trades are routed through the 0x Swap API, which charges a 0.15% fee on some pairs. TELx adds no fee of its own. The tool can also convert directly into the eUSD stablecoin and works across Ethereum, Polygon and Base.

What changed for TELx users

According to the project's public code repository, the only swap previously available on TELx was the eUSD vault, which handled native USDC to and from eUSD at a 1:1 rate through the Peg Stability Vault. A development ticket notes that liquidity providers holding other assets, such as ETH, had to swap elsewhere before adding liquidity or using the vault. The ticket cites liquidity provider feedback asking for swap support for other assets.

The new feature closes that gap. Telcoin's code notes that the integration uses the 0x Swap API v2, and that TELx sends no fee parameters of its own with each quote. The interface also offers a link to make the same swap on Uniswap for users who prefer it, according to the project's pull request on fee disclosure.

How the 0x fee works

0x says on its pricing page that, on its standard plan, it charges a 0.15% fee on swaps involving select token pairs. The company states that the list of eligible tokens changes over time and that any fee is detailed in each API response when it applies. This explains why the cost varies by trading pair on TELx.

For users, the practical effect is fewer steps. Swapping, pooling and reward collection can now happen in one place, which reduces the need to move funds between venues before providing liquidity. The 0x Swap API covers 16 EVM networks, according to 0x, so TELx's three-chain support is a subset of what the API can reach.
