Asset Issuer Integration

​

Overview

If you issue an asset that settles on a delay — a tokenized treasury, a bond fund, a yield-bearing stablecoin, a structured vault — Sprinter can front the liquidity so your holders enter and exit instantly, while the underlying settles on your own rail in the background. Your tokenized asset is onboarded first. Sprinter quotes only assets it has underwritten, allocated liquidity to and configured routes for, so onboarding is step 1 and the runtime calls follow from there. Two paths. The solver model described here gets you live without protocol changes. The facility model commits dedicated capacity and is agreed commercially — see Redemption & Subscription Liquidity. The sequence is one onboarding phase, then three runtime steps per redemption:

1. Onboard the asset — one time. Underwriting, liquidity allocation, route configuration
2. Quote — ask Sprinter what it will pay for the position
3. Create intent — publish the redemption as an exclusive limit order to Sprinter
4. Settle — Sprinter fills instantly; you settle the underlying on your rail

Step 1 — Onboard the asset

This is a joint process, not a self-serve API call. Sprinter has to understand the settlement path before it will lend against it, then commit capital and wire up routing.

​

What you submit

​

Confirm the asset is live

Before wiring up runtime calls, check that your token is returned by supported tokens for a chain. If it isn’t there, onboarding is not complete and quotes will not return.

Runtime flow

Once the asset is live, this runs per redemption.

​

Step 2 — Request a quote

Ask the Sprinter Liquidity API what it will pay for the position on the holder’s chosen chain. See Get the borrow quote for the request and response schema. The quote returns a price and the address that will fill it. Keep that address — step 3 needs it.

​

Step 3 — Create the intent

Publish the redemption as an intent through your intent protocol — for example with the LI.FI SDK, creating a LI.FI intent. Two things matter:

• Create it as an exclusive limit order, not an open order
• Set the quote’s address as the exclusive filler, so only Sprinter can fill at the quoted price

This is what makes the fill deterministic: the holder is quoted a price, and that exact price is what fills.

​

Step 4 — Settle, or reclaim

If filled: the holder receives USDC immediately on their chosen chain. Sprinter holds the position and settles it through your native rail. When settlement completes, Sprinter is repaid and the capital recycles into the next fill. If the intent expires unfilled: you reclaim the funds on the intent contract. Nothing is stranded — an unfilled intent is a no-op.
