Telegram Bot SDK Upgrade and Bug Fixes
Swaptain is a Telegram-based cryptocurrency swapping bot built with Bun, TypeScript, grammY, and deployed on Fly.io with Prisma for session storage. It uses Swapkit SDK to provide cross-chain swaps. A previous contractor began upgrading the bot from SwapKit v1 → v4 and completed most of the migration work. However, several critical issues remain unresolved, preventing reliable use in production.
Swaptain is seeking a qualified agency or developer to complete the migration, fix the remaining errors, and deliver a fully working and tested Telegram bot.
The prior team completed significant parts of the v4 upgrade but did not finish the task. The main known issues include:
Quotes intermittently not showing
Transactions failing or not executing reliably
Incorrect or missing balance display
Potential state-handling or listener issues in bot scenes
Remaining cleanup related to new SwapKit v4 asset/chain types
General stability/performance issues across flows and improvements to be made.
You will be given full access to the GitHub repo, Fly.io environment, env keys, and deployment logs.
In your proposal, please include:
Experience with Cryptocurrencies
Relevant experience with SwapKit, cross-chain swap frameworks, or similar SDKs
Experience with grammY, Telegram bots, Bun/Node, Fly.io, and Prisma
Estimated timeline to complete the migration & debugging
Pricing model (fixed, hourly, milestone-based)
