Portals

What are Portals?​

Portals are smart contracts and adapters that take advantage of and build upon the composability of DeFi. They enable anyone to create complex interactions by bundling actions from various platforms together to create atomic transactions. This allows for a wide range of use cases that were not possible before.

With over 20,000 supported tokens across the most popular EVM chains, the combinations are endless!

Gas-free Transactions​

Gas-free transactions are powered by the Galaxy Broadcasting System (GBS). The GBS allows you to execute any transaction without having to worry about gas, failed or stuck transactions, and you do not need to hold the native token of the chain you are using.

The GBS works automatically in the background and allows any token to be used for gas, including LP tokens. In addition, the GBS works with any protocol, including for swaps executed on Curve.fi, Uniswap, or Balancer, or for zaps on protocols like Gearbox or Convex.

Any-to-Any Swaps​

With Portals, you can swap almost any transferrable ERC20 token for another token. For example, you can trade a Yearn Vault token for a Beefy Vault token, or swap a Stargate LP token for a Curve LP token directly.

Swap Example

Single sided liquidity​

Portals also enables you to add or remove liquidity from multi-asset opportunities like Curve pools, Yearn vaults, and more with a single token. For example you can enter a Yearn vault containing the Curve 3EUR LP (agEUR, EURT, and EURS) with WBTC and then exit into USDC before moving onto another opportunity.

Is there a Fee?​

Portals charges a default fee of 0.3% per transaction. API users can adjust the fee to fit their needs between 0-1%. Fees generated from API users are shared between Portals and the API user. Reach out to the Portals team here to learn more about the Partners program.
