Project description:
"I run an existing cryptocurrency exchange built entirely in PHP and I’m ready to push it to the next level. Right now I need someone who can do two things at once: introduce fresh functionality and resolve a handful of stubborn bugs.

Scope of work
• Wallet integration comes first. You’ll connect hot / cold wallets so deposits, withdrawals, and balance checks operate smoothly and securely.
• Strengthen user account management—registration, KYC flow, and session handling must be airtight.
• Optimise the trading engine for faster order matching and accurate fee calculation.
• Tidy up two specific pages, add a few internal links, and squash any lingering site-wide glitches.

All code is PHP (Laravel base with some custom components). Good grasp of API security, cryptographic libraries, and exchange workflows (order books, balances, confirmations) is essential.

Deliverables
1. Fully functioning wallet integration tested on testnet and mainnet.
2. Updated account-management and trading modules with no regression errors.
3. Refactored pages and new links live in production.
4. Brief deployment notes plus a short video or screenshare proving success of each item.

I’ll supply full repo access, current bug list, and detailed endpoints. Once you review, quote me a single fixed price and timeline. If you have successfully delivered exchange features before, I’d like to see a repo snippet or demo URL when you respond.
Plus, I will need a wallet-to-wallet fiat transfer using my customers name and the account ID" (client-provided description)
