# Fees & Transaction Costs As transparency is a core principle of Sierra, this section clearly describes all forms of fees and transaction costs that may be encountered while using SIERRA, including: * Gas fees that are required to send transactions on the Ethereum and Avalanche blockchains, where Ethereum's gas fees are denominated in ETH and typically higher than fees in AVAX on Avalanche * Swap fees charged by DEXes and paid to solely to liquidity providers (LPs) of SIERRA. We have set up DEX pools on LFJ charge 10 basis point (bps) fees * Swaps executed via the Swap page on SIERRA's website currently do not charge any additional fees beyond fees paid to LPs of DEXes and gas fees. In the future, an additional Swap fee on the SIERRA website may be charged, where all proceeds go to the SIERRA treasury wallet * OpenTrade, as the service provider that manages all of SIERRA's reserves, charges a platform fee of 25 bps per annum on all yield earned in DeFi yield sources and 50 bps per annum on all yield earned in RWA yield sources. There are no management, withdrawal, deposit or other fees charged by OpenTrade on SIERRA's reserves for the services provided to the Sierra protocol * Currently, the Sierra protocol does not charge any fees on the total yield generated by the portfolio of reserve collateral. In the future, an additional fee on the yield generated by SIERRA's reserves may be charged, where all proceeds go to the SIERRA treasury wallet Any changes to these fees will be transparently communicated across Sierra's official channels. There are no other hidden fees or costs of using SIERRA. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
