white paper

Launched on 20/01/2022, by a team based in Singapore, Ruyi wallet aims to bridge the gap between CeFi and DeFi. This is a hybrid one-stop-shop cryptocurrency wallet that can be used for billing, utilities, point of sale, payroll, remittance, messaging, and C2C transactions. It will eliminate the need to do multiple transfers of digital assets which will lessen the transaction fee, avoid potential errors, and block potential security risks. Bid your goodbyes to unnecessary multiple hard-to-use haphazard applications that take up so much of our time. Ruyi solves all of that with a hassle-free, seamless, secure, and easy to use wallet.

Pragma version0.8.11 (#1) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.11 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#178-206):
