USDI On-Ramp and Off-Ramp Options on CKB?

English
1

Hi everyone,

I’m looking into using USDI as a stablecoin for payments and settlement.

I’d like to understand the current recommended pathways for both:

1. Fiat → USDI

  • Is there any direct fiat on-ramp that supports USDI?

  • If not, what is the standard route?

    • Buy USDC/USDT on a CEX?

    • Bridge to CKB?

    • Swap to USDI on-chain?

  • Which exchanges or bridges are currently reliable and liquid for this flow?

2. USDI → Fiat

  • What is the recommended process for converting USDI back to fiat?

  • Is the typical path:

    • Swap USDI → USDC/USDT

    • Bridge out

    • Send to CEX

    • Withdraw to bank?

  • Are there any integrations or partners that support more direct off-ramp flows?

It would be helpful to know:

  • Supported regions (US / Asia / EU, etc.)

  • Liquidity considerations

  • Any compliance or KYC constraints to be aware of

  • Estimated fees across the full flow

Appreciate any concrete links, tooling recommendations, or production-tested workflows.

Hey @CDEX, good questions!!

I’d like to have more official answers about this kind of things too! Since we are also integrating USDi in CommunityDAO v1.1, it makes sense for potential builders (who gonna potentially request funding to be paid out in USDi) to understand these very details.

From what I know, there are currently two paths for USDI on/off-ramp:
1. For retail-sized swaps, you can use DestBridge to swap between USDI and Ethereum-side USDT:

2. For larger OTC-level demand, you may consider contacting IPN directly to discuss liquidity arrangements:

Glad someone asked, I wasn’t aware of this possibility, thank you @zz_tovarishch!! :hugs:

BTW, it’s pretty funny: given the currently available information, USDi could just be a glorified bridged USDT and we would be none the wiser. That why I still hold hope for (some of) the OP questions being replied publicly here for everyone to read and learn from them.

Love & Peace, Phroi

PS: On a positive note, DestBridge fees are really low compared to the 0.5+% of Rosen Bridge. Also, Rosen Bridge will never support USDT:

Clawback and freeze exclusion: The bridge commingles deposits from many users into shared custody cells. If an issuer froze the bridge address, all bridged representations of that token would become unbacked at once, affecting every holder across every connected chain. Rosen Bridge therefore excludes tokens with issuer-controlled freeze or clawback capabilities as a protocol-level policy.

Any reason why it won’t support USDT?

Hi CDEX, this is ZOE from IPN (the issuer of USDI).

Regarding your question, here’s some information for your reference:

  1. Currently, USDI is only issued through institutions that have undergone KYC and AML procedures. It currently supports USDT and USDC exchange, but not fiat currency exchange.

  2. Similarly, when institutions redeem through IPN, the exchange will be back to USDT or USDC.

If your goal is to enable exchange with fiat currency, you’ll need to utilize other institutions. However, currently, all feasible methods require exchanging for USDT or USDC, which is also a challenge we face; direct exchange with fiat currency is not currently possible.

Of course, with the continued development of the ecosystem, there may be an opportunity to introduce USDI to exchanges, enabling two-way exchange with fiat currency through the exchange’s exchange system.

I hope this information is helpful.

Never expected my hunch to be right, but glad to see more transparency on USDI, keep it up!!

Thank you @IPN & @zz_tovarishch for your services, Phroi
