Publication number: 20220391982Abstract: A decentralized investment fund operates according to consensus code on a shared ledger and raises capital by issuing ownership tokens on the shared ledger. The decentralized investment fund may hold digital assets in the consensus code and distribute profits to the token owners according to each owner's dividend preference. A token owner's dividend preference can include digital assets tracked by a different shared ledger, stabletoken digital assets pegged to the value of a digital asset, and cross-chain digital asset swaps. Token issuance may include a proof of accreditation requirement based on cryptographic proof on a shared ledger. The decentralized investment fund may distribute fund documents to the token holders by encrypting the document, first with a symmetric key common to all token holders, and second with an asymmetric key unique to each token holders and based on the token's holder's known public address on the shared ledger.Type: ApplicationFiled: August 15, 2022Publication date: December 8, 2022Inventors: Matthew Hill, Gregory Bell, Shawn Owen

Publication number: 20220366491Abstract: A multisig digital asset wallet stores collateral for a loan between a borrower and a lender. The borrower and lender agree to loan terms including collateralization requirements. Over the course of the loan repayment period, a Loan-to-Value (LTV) ratio between the digital asset collateral and the loan principal balance will change due to fluctuations in the market exchange value of the digital asset and a declining loan principal balance due to regular loan repayments by the borrower. If the LTV exceeds the collateral requirements by an overage amount, then the borrower may sign a transaction and request signatures from other participants to withdraw funds from the multisig collateral wallet. If the LTV fails to satisfy the collateral requirements, participants may spend funds from the multisig collateral wallet to improve the LTV, catch up after a missed payment by the borrower, or pay down the loan principal.Type: ApplicationFiled: March 29, 2022Publication date: November 17, 2022Inventors: Matthew Hill, Gregory Lloyd Bell, Shawn Owen

Publication number: 20190114706Abstract: A blockchain oracle manages loans collateralized by a digital asset. Lenders and borrowers agree to loan terms that include digital asset collateral held in a multisig wallet for which various parties hold private keys. If collateral requirements are not met by the loan such as when a Loan-to-Value ratio satisfies a margin call condition, the oracle may transmit warnings to loan participants and may initiate liquidation of the digital asset collateral to remove the margin call condition. The oracle may exist on a blockchain initialized with loan agreement information. The oracle may determine whether margin call and liquidation conditions are satisfied by updating an internal state by obtaining and/or receiving information regarding the status of the loan, the digital asset collateral, and liquidation locations on-chain, by receiving status transactions, and/or by requesting the information directly.Type: ApplicationFiled: October 17, 2018Publication date: April 18, 2019Applicant: SALT Lending Holdings, Inc.Inventors: Gregg Bell, Matthew Hill, Shawn Owen
