Overview
Crypto finance platforms need to handle the complexity of multiple blockchains while offering a simple user experience. Rely unifies asset management across Ethereum, Tron, Bitcoin, and Binance Smart Chain in a single interface.
The system automatically generates addresses for each blockchain when a user registers, monitors on-chain balances in real-time, and allows transfers both between platform users and to external wallets.

Staking system
We implemented two staking modes: fixed with configurable lock period offering higher APR, and flexible allowing withdrawals at any time. Rewards are automatically calculated based on lock days.
The system tracks each staking position individually, allowing partial unstaking and claiming of accumulated rewards. Blockchain listeners automatically detect deposits and credit them to the corresponding accounts.
Multi-layer security
Authentication combines JWT with TOTP-based 2FA. The KYC process requires uploading identity documents that are stored securely. Wallet private keys are encrypted with crypto-js before persisting.
Each withdrawal goes through network-specific blockchain address validations, verifying format and checksum before processing the transaction.
