What is Pay Protocol?
Pay Protocol is the first open-source, self-custodial crypto acquiring protocol.
We provide retail businesses, fintechs, financial institutions, and Web3 companies a self-custodial crypto acquiring infrastructure, enabling their customers to pay, deposit, and withdraw cryptos seamlessly.
How does Pay Protocol work?
Pay Protocol is a decentralized digital asset payment system that allows businesses to securely process, deposit, and withdraw cryptocurrencies without relying on third-party custodians. Through the use of smart contracts, Pay Protocol ensures that every transaction is transparent, secure, and fully controlled by the clients.
Unlike traditional payment systems, Pay Protocol eliminates the need for private keys and centralized management. Instead, it offers a keyless system that enables businesses and customers to retain complete ownership of their assets, greatly reducing the risk of theft or mismanagement.
The platform uses advanced techniques to optimize transaction costs, reducing gas fees by up to 95%. Additionally, Pay Protocol integrates multi-signature security, ensuring that critical actions like fund transfers require approval from multiple trusted parties, further safeguarding assets.
Businesses can easily integrate Pay Protocol into their existing systems via APIs, making it simple to accept cryptocurrency payments across different blockchain networks. This flexibility and efficiency make Pay Protocol an ideal solution for any business looking to adopt crypto payments securely and cost-effectively.
What is the difference between the Pay Protocol solution and the MPC solution?
The Pay Protocol solution utilizes a keyless, pure smart contract solution, meaning that no customer private key information is stored or indirectly managed in the system services provided. It offers peer-to-peer network services for users with decentralization and security equivalent to that of Layer 1 public blockchains.
The MPC solution, on the other hand, uses private key sharding technology and mathematical encryption principles to secure servers and reduce the risk of private key loss. The downside is the need for server maintenance and ensuring the security of all server nodes, as well as the reliability of the encryption scheme.
Pay Protocol does not require server security. Even in the extreme case where the Pay Protocol payment server is compromised, user funds remain secure. However, currently, Pay Protocol only supports a keyless solution within EVM-compatible environments.
What is the difference between Pay Protocol's multi-signature and traditional wallet's
multi-signature?
Pay Protocol's multi-signature solution is a system-wide multi-signature approach, which is more suitable for serving B2B clients compared to traditional wallet multi-signature solutions.
The system multi-signature involves multiple super admins who collectively manage the permissions of multiple smart contracts. This is more complex than the single wallet multi-signature management solution and requires the configuration of more system business parameters to adapt to different B2B scenarios.
For this purpose, Pay Protocol's backend management system includes a system multi-signature configuration module, which not only manages wallet security but also includes system security policy configurations (such as financial personnel allocation, setting the hot wallet addresses, and defining the amount transferred daily from cold contracts to hot wallets). This offers more practical and personalized configuration options for Web3 payment business scenarios.
How does Pay Protocol reduce gas costs for fund consolidations?
In EVM environments, gas fees are closely tied to the amount of data stored on the blockchain. By optimizing the storage structure and utilizing data compression technologies, Pay Protocol is able to reduce the amount of data stored in contracts, thus lowering gas consumption.
While most of Pay Protocol's regular business contracts are developed using Solidity, the core transaction parts are developed using lower-level assembly language. Additionally, the use of contract mapping technology and off-chain computation dramatically reduces gas costs when the results are finalized on-chain.
