Side's usage scenarios are similar to banks. With lending as the core, it unlocks the full financial potential of Bitcoin and is also known as Bitcoin's "on-chain bank".
Side's lending product is a self-hosted liquidity lending protocol. The core DLC of its infrastructure is a Bitcoin smart contract framework based on an oracle.
DLC allows conditional payments to be executed based on off-chain events without the need for third-party custody of funds. DLC uses cryptographic techniques such as multi-signature transactions, hashed time lock contracts (HTLCs), Schnorr signatures, and Adaptor signatures to ensure user rights while achieving security and non-custodial nature.
