IBC Connect: The easiest way for appchains to request managed relayer connections


IBC Connect: verify existing relayers and easily set up new relayer connections

The promise of IBC is that sovereign blockchains can speak the same language, building a web of interconnected chains and applications that can send any type of data. But how are these connections actually set up and maintained?

This is where IBC Connect from TFM comes in: a tool for interchain L1 teams to set up relayer connections between their appchain and as many other Cosmos SDK chains as required.

Through an intuitive user interface, appchain teams can request new connections as well as have TFM provide redundancy for existing connections. TFM have already set up multiple relayers for existing connections, helping to revert transactions that had got stuck.

Who is IBC Connect for?

IBC Connect is targeted at Cosmos SDK chain core teams. TFM aims to provide high quality relayer services, increasing connectivity throughout the interchain. Any Cosmos SDK chain can request TFM to set up new relayers or provide redundancy for existing connections.

What problem does IBC Connect solve?

Cosmos SDK chain teams often need to establish and manage relationships with a broad set of relayers or run relayers in-house. The resource constraints this process necessitates can become a drag on even the most robust team. TFM has launched IBC Connect as a way to improve the day-to-day experience of relayer management for appchain teams.

Since the launch of IBC Bridge, the precursor to IBC Swap & IBC Transfer, on March 17th 2023, TFM has learned that relayer reliability is fundamental to successful cross chain interactions. TFM manages the front end, back end and smart contracts. Managing the relayer connections as well makes practical sense by bringing more of the process under direct control of TFM — meaning they can have more of an influence on each step of the process, and users can experience improved cross-chain transaction flow.

How long until the relayers are active?

When a verified member of an interchain appchain submits a relayer request, TFM is able to set up the relayers within 1 hour of confirming receipt of the configuration file, generated on the IBC Connect dapp. A team member known to TFM should submit the configuration link via Telegram.


How IBC Connect works

– Select the appropriate appchain

– On the left, there is a drop down menu showing existing connections to other appchains

– On the right, appchain teams can select additional connections to other appchains as well as additional relayers for existing connections. Once the appropriate appchains have been selected, simply turn on the Enable TFM IBC-Connect toggle to generate a configuration link. Discussion with TFM, via Telegram, is necessary to confirm the authenticity of the request, and that’s it. Within an hour, all the requested relayer connections will be available.

IBC Connect makes it easy to outsource IBC relayer connections, meaning appchains can focus on their core mission. With more relayers running, the interchain will continue to become more robust, helping to provide a more seamless experience for users.

Simplifying cross-chain UX: Meet TFM’s Widget, SDK and API for interchain app developers


From stkATOM on Persistence to ASTRO on Neutron in 1-click

Appchains are great. The interchain is home to over 50+ purpose-specific application chains, each of which attempts to provide the best functionality and user experience for their specific use-case.

What’s not great, is the user experience (UX) for navigating across these chains. While the interchain’s IBC protocol ensures transferring tokens are fast, secure and cheap, the process of actually moving and swapping tokens across chains is not seamless.

To solve this interchain UX problem, TFM introduced IBC Swap last month — a single, simple interface that allows users to transfer and swap their tokens across 4 different chains — with just 1 click!

This was great. TFM.com users now had a simpler way to use the interchain. But we weren’t happy with that.

And so, today, we unveil 3 ways for every dApp, chain and user interface developers in the interchain to deploy this new seamless user experience easily.

The TFM IBC Widget, SDK, and API together form a cohesive suite of tools that equip developers with everything they need to build groundbreaking decentralized applications. Whether you prefer a ready-made widget, a feature-rich SDK, or a versatile API, TFM offers a solution tailored to your needs.

IBC Swap — simplifying swaps and transfers across the interchain


IBC Swap — simplifying swaps and transfers across the interchain

Introducing IBC Swap — a solution by TFM to significantly simplify the process of cross-chain swaps in the interchain, making it easier and more efficient for users to move and use their tokens across different chains.

The interchain is a fast-growing ecosystem with over 50 IBC connected chains, made up of both Cosmos-SDK appchains and now, Polkadot chains too. While it is commendable that IBC connects these chains for secure cross-chain token transfers, the user journey for actually swapping and transferring tokens between chains is kinda “broken”.

IBC Swap benefits users by abstracting away the complexity of moving tokens around the interchain. Instead of initiating multiple transactions on multiple dApps, IBC Swap helps users swap tokens from anywhere, to anywhere, in one seamless interface.

For example, currently, if a user wants to use ATOM they hold on the Persistence chain to buy an NFT with STARS on Stargaze, there are four steps that must completed:

  1. Persistence: Transfer ATOM from Persistence to Cosmos Hub
  2. Osmosis: Deposit ATOM from Cosmos Hub into Osmosis
  3. Osmosis: Swap ATOM for STARS on Osmosis
  4. Osmosis: Withdraw STARS from Osmosis to Stargaze
IBC Swap

For experienced users, the flow is understood, it just takes the user time to conduct the transactions. For newer users, this process is overwhelming.

This user journey is not the fit for the mass adoption that the interchain is gearing up for.

What is TFM’s IBC Swap?

IBC Swap combines cross-chain swaps and transfers into a single interface. The flow for users is much simpler than making separate transactions for each step in a cross chain swap.

The four steps above can be combined into a single process on the IBC Swap Terminal.

  • IBC Swap will transfer the $ATOM from Persistence -> Cosmos Hub -> Osmosis
  • Perform the token swap from $ATOM to $STARS, with no additional fees
  • Then transfer the $STARS from Osmosis -> Stargaze
  • All, in just 2 clicks!

At TFM, we spent a lot of time working to simplify the interchain journey. Our team integrated Axelar’s Asset Transfer module, Packet Forward Middleware, and utilized IBC Hooks to reduce the number of transactions required to be signed in wallet.

Of course, we would like to further reduce the number of wallet-prompts the user receives, but despite this, the ability to perform cross-chain swaps and transfers from a single interface already greatly simplifies the process for the end user.

What might the future hold for IBC Swap?

Perhaps instead of using IBC Swap to move tokens and then shop on TFM’s interchain NFT Aggregator, users can go straight to the NFT Aggregator, find an NFT they want to purchase and then select a payment token from any network within the interchain.

The whole IBC Swap side of things could become obfuscated so users simply don’t need to worry about transferring tokens. IBC Swap works in the background, abstracting away the complexity of cross-chain swaps, making it easier, and helping to onboard the next wave of users to the interchain.

So, how do you use IBC Swap?

Here is a step-by-step guide to using IBC Swap — on https://tfm.com

Empty IBC Swap box

Visitors to TFM IBC Swap are presented with this swap box. Users must select From Network and Token as well as To Network and Token.

When they click on one of the drop-downs above, they are presented with the following model window. Continuing with the example above, we simply select From Persistence ATOM, To Stargaze STARS. Then press Save & Close.
