VWallet
A non-custodial multi-chain wallet where users could send, swap and use dApps across all supported chains in one place under one keypair. It's empowered by vToken, which represents chain-agnostic purchasing power and backed by equivalent actual assets distributed across chains.

Problem Statement
VWallet is a new type of wallet that focuses on optmization of user's experience while not sacrificing decentralization and non-custodial properties. We uses credit card / ACH and combines multichain native stablecoins like USDC to deliver seamless on/off ramp process. User would mainly interact with vToken, which is just a balance number stored on contract, but users can use the balance to permissionlessly gain access to all defi / nft / literally any dapps on any supported chains, currently the job of maintaining such virtual balance is a contract deployed on Ethereum Goerli, and it's the contract user directly interact with (so user only need to have 1 keypair in total), and the contract checks whether user owns enough virtual balance, if so, use general messaging protocol like Axelar / Hyperlane to relay the transaction to different chains' deployed vault contract, e.g. on Avalanche c-chain, it's called VaultAvax, which already holds the actual assets and thus do the actual jobs. In this way, we minimize the bridging efforts and provide a true bridgeless user experience. 100% hit rate (the rate that there's enough balance on local chain so don't need bridge at all) requires smart rebalancing and cross-chain JIT liquidity provision which is an innovative mechanism that rewards market maker to compete on ability to predict future volume on each chain.
