Welcome to the official documentation portal for SiO2 Finance
SiO2 Finance, adapted from Aave v2 with veToken mechanism embedded, is the 1st multi-VM lending hub in Astar and Polkadot ecosystem, supporting both EVM and WASM runtime and native assets


SiO2 Finance is the multi-VM lending hub on Astar for Polkadot. Silicon dioxide (SiO2) is an oxide of Silicon and the major component of crystal, the purest gem in the natural world.
SiO2 Finance is designed to serve the Astar/Polkadot community with the best user experience, easy-to-use one-click features, and transparent governance.
SiO2 Features:
  • Lending/borrowing: allow users to use multiple assets as collateral and borrow other assets
  • Depositing: allow users to deposit multiple assets and earn passive income from interests
  • veStaking: incentivize long-term token holders over short-term holders with $SIO2
  • One-click flashloan: allow users to use flashloan for position migration (e.g., move position from one protocol to another in seconds) and arbitrages without coding
  • One-click short position: allow users to short an asset with only one click
  • Multi-VM support: both EVM and WASM will be supported on one frontend.
We aim to build multiple one-click solutions and become the most user-friendly lending product on Astar for Polkadot.

What is SiO2

SiO2 is a protocol for users to quickly and easily deposit and borrow assets on Astar Network. Depositors can provide liquidity to earn interest as a stable passive income, while borrowers can leverage their assets without selling them out.
It is a public, decentralized marketplace of assets that can be accessed not only by a user but also by bots and other DeFi protocols. In addition, SiO2 provides a comprehensive set of lending features, with a focus on the assets handled on Astar.
